Most malaria models to date assume constant or linear responses of mosquito and parasite life-history traits to temperature, predicting optimal transmission at 31 °C. These models are at odds with field observations of transmission dating back nearly a century. We build a model with more realistic ecological assumptions about the thermal physiology of insects. Our model, which includes empirically derived nonlinear thermal responses, predicts optimal malaria transmission at 25 °C (6 °C lower than previous models). Moreover, the model predicts that transmission decreases dramatically at temperatures > 28 °C, altering predictions about how climate change will affect malaria. A large data set on malaria transmission risk in Africa validates both the 25 °C optimum and the decline above 28 °C. Using these more accurate nonlinear thermal-response models will aid in understanding the effects of current and future temperature regimes on disease transmission.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","publisherLocation":"Hoboken, NJ","doi":"10.1111/ele.12015","usgsCitation":"Mordecai, E., Paaijmans, K.P., Johnson, L., Balzer, C., Ben-Horin, T., de Moor, E., McNally, A., Pawar, S., Ryan, S.J., Smith, T.C., and Lafferty, K.D., 2013, Optimal temperature for malaria transmission is dramatically lower than previously predicted: Ecology Letters, v. 16, no. 1, p. 22-30, https://doi.org/10.1111/ele.12015.","productDescription":"9 p.","startPage":"22","endPage":"30","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":262826,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":294052,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/ele.12015"}],"volume":"16","issue":"1","noUsgsAuthors":false,"publicationDate":"2012-10-11","publicationStatus":"PW","scienceBaseUri":"508ba304e4b0d7f30c14573f","contributors":{"authors":[{"text":"Mordecai, Erin A.","contributorId":9113,"corporation":false,"usgs":true,"family":"Mordecai","given":"Erin A.","affiliations":[],"preferred":false,"id":468459,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Paaijmans, Krijn P.","contributorId":62459,"corporation":false,"usgs":true,"family":"Paaijmans","given":"Krijn","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":468465,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Johnson, Leah R.","contributorId":83382,"corporation":false,"usgs":true,"family":"Johnson","given":"Leah R.","affiliations":[],"preferred":false,"id":468466,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Balzer, Christian","contributorId":41279,"corporation":false,"usgs":true,"family":"Balzer","given":"Christian","email":"","affiliations":[],"preferred":false,"id":468461,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ben-Horin, Tal","contributorId":58137,"corporation":false,"usgs":false,"family":"Ben-Horin","given":"Tal","email":"","affiliations":[],"preferred":false,"id":468464,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"de Moor, Emily","contributorId":48021,"corporation":false,"usgs":true,"family":"de Moor","given":"Emily","email":"","affiliations":[],"preferred":false,"id":468462,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"McNally, Amy","contributorId":53225,"corporation":false,"usgs":true,"family":"McNally","given":"Amy","affiliations":[],"preferred":false,"id":468463,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Pawar, Samraat","contributorId":22622,"corporation":false,"usgs":true,"family":"Pawar","given":"Samraat","email":"","affiliations":[],"preferred":false,"id":468460,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Ryan, Sadie J.","contributorId":102738,"corporation":false,"usgs":true,"family":"Ryan","given":"Sadie","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":468468,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Smith, Thomas C.","contributorId":101139,"corporation":false,"usgs":true,"family":"Smith","given":"Thomas","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":468467,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Lafferty, Kevin D. 0000-0001-7583-4593 klafferty@usgs.gov","orcid":"https://orcid.org/0000-0001-7583-4593","contributorId":1415,"corporation":false,"usgs":true,"family":"Lafferty","given":"Kevin","email":"klafferty@usgs.gov","middleInitial":"D.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":468458,"contributorType":{"id":1,"text":"Authors"},"rank":11}]}} ,{"id":70038186,"text":"70038186 - 2013 - The response of Lake Tahoe to climate change","interactions":[],"lastModifiedDate":"2012-12-18T17:00:57","indexId":"70038186","displayToPublicDate":"2012-11-01T00:00:00","publicationYear":"2013","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1252,"text":"Climatic Change","active":true,"publicationSubtype":{"id":10}},"title":"The response of Lake Tahoe to climate change","docAbstract":"Meteorology is the driving force for lake internal heating, cooling, mixing, and circulation. Thus continued global warming will affect the lake thermal properties, water level, internal nutrient loading, nutrient cycling, food-web characteristics, fish-habitat, aquatic ecosystem, and other important features of lake limnology. Using a 1-D numerical model - the Lake Clarity Model (LCM) - together with the down-scaled climatic data of the two emissions scenarios (B1 and A2) of the Geophysical Fluid Dynamics Laboratory (GFDL) Global Circulation Model, we found that Lake Tahoe will likely cease to mix to the bottom after about 2060 for A2 scenario, with an annual mixing depth of less than 200 m as the most common value. Deep mixing, which currently occurs on average every 3-4 years, will (under the GFDL B1 scenario) occur only four times during 2061 to 2098. When the lake fails to completely mix, the bottom waters are not replenished with dissolved oxygen and eventually dissolved oxygen at these depths will be depleted to zero. When this occurs, soluble reactive phosphorus (SRP) and ammonium-nitrogen (both biostimulatory) are released from the deep sediments and contribute approximately 51 % and 14 % of the total SRP and dissolved inorganic nitrogen load, respectively. The lake model suggests that climate change will drive the lake surface level down below the natural rim after 2085 for the GFDL A2 but not the GFDL B1 scenario. The results indicate that continued climate changes could pose serious threats to the characteristics of the Lake that are most highly valued. Future water quality planning must take these results into account.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Climatic Change","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","publisherLocation":"Amsterdam, Netherlands","doi":"10.1007/s10584-012-0600-8","usgsCitation":"Sahoo, G., Schladow, S., Reuter, J., Coats, R., Dettinger, M., Riverson, J., Wolfe, B., and Costa-Cabral, M., 2013, The response of Lake Tahoe to climate change: Climatic Change, v. 116, no. 1, p. 71-95, https://doi.org/10.1007/s10584-012-0600-8.","productDescription":"25 p.","startPage":"71","endPage":"95","ipdsId":"IP-037468","costCenters":[{"id":148,"text":"Branch of Regional Research-Western Region","active":false,"usgs":true}],"links":[{"id":262876,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":262875,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10584-012-0600-8"}],"country":"United States","state":"California;Nevada","otherGeospatial":"Lake Tahoe","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -120.165109,39.0 ], [ -120.165109,39.26 ], [ -120.0,39.26 ], [ -120.0,39.0 ], [ -120.165109,39.0 ] ] ] } } ] }","volume":"116","issue":"1","noUsgsAuthors":false,"publicationDate":"2012-10-11","publicationStatus":"PW","scienceBaseUri":"5094ec28e4b0e5cfc2acdd15","contributors":{"authors":[{"text":"Sahoo, G.B.","contributorId":49167,"corporation":false,"usgs":true,"family":"Sahoo","given":"G.B.","email":"","affiliations":[],"preferred":false,"id":463614,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schladow, S.G.","contributorId":92791,"corporation":false,"usgs":true,"family":"Schladow","given":"S.G.","email":"","affiliations":[],"preferred":false,"id":463618,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Reuter, J.E.","contributorId":9539,"corporation":false,"usgs":true,"family":"Reuter","given":"J.E.","email":"","affiliations":[],"preferred":false,"id":463612,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Coats, R.","contributorId":9540,"corporation":false,"usgs":true,"family":"Coats","given":"R.","email":"","affiliations":[],"preferred":false,"id":463613,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Dettinger, M. 0000-0002-7509-7332","orcid":"https://orcid.org/0000-0002-7509-7332","contributorId":78909,"corporation":false,"usgs":true,"family":"Dettinger","given":"M.","affiliations":[],"preferred":false,"id":463616,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Riverson, J.","contributorId":63692,"corporation":false,"usgs":true,"family":"Riverson","given":"J.","affiliations":[],"preferred":false,"id":463615,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Wolfe, B.","contributorId":79000,"corporation":false,"usgs":true,"family":"Wolfe","given":"B.","email":"","affiliations":[],"preferred":false,"id":463617,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Costa-Cabral, M.","contributorId":96554,"corporation":false,"usgs":true,"family":"Costa-Cabral","given":"M.","affiliations":[],"preferred":false,"id":463619,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}} ,{"id":70040568,"text":"70040568 - 2013 - Safety of florfenicol administered in feed to tilapia (Oreochromis sp.)","interactions":[],"lastModifiedDate":"2013-05-20T09:27:58","indexId":"70040568","displayToPublicDate":"2012-10-31T00:00:00","publicationYear":"2013","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3607,"text":"Toxicologic Pathology","active":true,"publicationSubtype":{"id":10}},"title":"Safety of florfenicol administered in feed to tilapia (Oreochromis sp.)","docAbstract":"The safety of Aquaflor® (50% w/w florfenicol [FFC]) incorporated in feed then administered to tilapia for 20 days (2x the recommended duration) at 0, 15, 45, or 75 mg/kg body weight/day (0, 1, 3, or 5x the recommended dose of 15 mg FFC/kg BW/d) was investigated. Mortality, behavioral change, feed consumption, body size, and gross and microscopic lesions were determined. Estimated delivered doses were >96.9% of target. Three unscheduled mortalities occurred but were considered incidental since FFC-related findings were not identified. Feed consumption was only affected during the last 10 dosing days when the 45 and 75 mg/kg groups consumed only 62.5% and 55.3% of the feed offered, respectively. There were significant, dose-dependent reductions in body size in the FFC-dose groups relative to the controls. Treatment-related histopathological findings included increased severity of lamellar epithelial hyperplasia, increased incidence of lamellar adhesions, decreased incidence of lamellar telangiectasis in the gills, increased glycogen-type and lipid-type hepatocellular vacuolation in the liver, decreased lymphocytes, increased blast cells, and increased individual cell necrosis in the anterior kidney, and tubular epithelial degeneration and mineralization in the posterior kidney. These changes are likely to be of minimal clinical relevance, given the lack of mortality or morbidity observed.

The recent emergence of white-nose syndrome (WNS), a fungal disease causing unprecedented mortality among hibernating bats of eastern North America, has revealed a knowledge gap regarding fungal communities associated with bats and their hibernacula. We used culture-based techniques to investigate the diversity of fungi in soil samples collected from 24 bat hibernacula in the eastern United States. Ribosomal RNA regions (internal transcribed spacer and partial intergenic spacer) were sequenced to preliminarily characterize isolates. Geomyces species were one of the most abundant and diverse groups cultured, representing approximately 33% of all isolates. Geomyces destructans was isolated from soil samples from three hibernacula in states where WNS is known to occur, and many of the other cultured Geomyces isolates likely represent undescribed taxa. Further characterization of the diversity of fungi that occur in hibernacula will both facilitate an improved understanding of the ecology of G. destructans within this complex fungal community and provide an opportunity to identify characteristics that differentiate G. destructans from non-pathogenic relatives.

ecosystems and water resources of the United States","docAbstract":"

Nearly all freshwaters and coastal zones of the US are degraded from inputs of excess reactive nitrogen (Nr), sources of which are runoff, atmospheric N deposition, and imported food and feed. Some major adverse effects include harmful algal blooms, hypoxia of fresh and coastal waters, ocean acidification, long-term harm to human health, and increased emissions of greenhouse gases. Nitrogen fluxes to coastal areas and emissions of nitrous oxide from waters have increased in response to N inputs. Denitrification and sedimentation of organic N to sediments are important processes that divert N from downstream transport. Aquatic ecosystems are particularly important denitrification hotspots. Carbon storage in sediments is enhanced by Nr, but whether carbon is permanently buried is unknown. The effect of climate change on N transport and processing in fresh and coastal waters will be felt most strongly through changes to the hydrologic cycle, whereas N loading is mostly climate-independent. Alterations in precipitation amount and dynamics will alter runoff, thereby influencing both rates of Nr inputs to aquatic ecosystems and groundwater and the water residence times that affect Nr removal within aquatic systems. Both infrastructure and climate change alter the landscape connectivity and hydrologic residence time that are essential to denitrification. While Nr inputs to and removal rates from aquatic systems are influenced by climate and management, reduction of N inputs from their source will be the most effective means to prevent or to minimize environmental and economic impacts of excess Nr to the nation’s water resources.

In the discontinuous permafrost of Yukon Flats, interior Alaska (USA), these changes have been non-uniform across adjacent watersheds, suggesting local controls on lake water budgets. Mechanisms that could explain the decreasing mass of one lake in Yukon Flats since the early 1980s, Twelvemile Lake, are identified via a scoping analysis that considers plausible changes in snowmelt mass and infiltration, permafrost distribution, and climate warming. Because predicted changes in evaporation (2 cmyr-1) are inadequate to explain the observed 17.5 cmyr-1 reduction in mass balance, other mechanisms are required. The most important potential mechanisms are found to involve: (1) changes in shallow, lateral groundwater flow to the lake possibly facilitated by vertical freeze-thaw migration of the permafrost table in gravel; (2) increased loss of lake water as downward groundwater flow through an open talik to a permeable subpermafrost flowpath; and (3) reduced snow meltwater inputs due to decreased snowpack mass and increased infiltration of snowmelt into, and subsequent evaporation from, fine-grained sediment mantling the permafrost-free lake basin.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hydrogeology Journal","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","publisherLocation":"Amsterdam, Netherlands","doi":"10.1007/s10040-012-0896-5","usgsCitation":"Jepsen, S., Voss, C., Walvoord, M.A., Rose, J., Minsley, B., and Smith, B.D., 2013, Sensitivity analysis of lake mass balance in discontinuous permafrost: the example of disappearing Twelvemile Lake, Yukon Flats, Alaska (USA): Hydrogeology Journal, v. 21, no. 1, p. 185-200, https://doi.org/10.1007/s10040-012-0896-5.","productDescription":"16 p.","startPage":"185","endPage":"200","costCenters":[{"id":148,"text":"Branch of Regional Research-Western Region","active":false,"usgs":true}],"links":[{"id":262685,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":262682,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10040-012-0896-5"}],"country":"United States","state":"Alaska","otherGeospatial":"Twelvemile Lake;Yukon Flats","volume":"21","issue":"1","noUsgsAuthors":false,"publicationDate":"2012-09-07","publicationStatus":"PW","scienceBaseUri":"508018ace4b0a0242ef285dd","contributors":{"authors":[{"text":"Jepsen, S.M.","contributorId":81356,"corporation":false,"usgs":true,"family":"Jepsen","given":"S.M.","email":"","affiliations":[],"preferred":false,"id":468265,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Voss, C.I.","contributorId":79515,"corporation":false,"usgs":true,"family":"Voss","given":"C.I.","email":"","affiliations":[],"preferred":false,"id":468263,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Walvoord, Michelle Ann 0000-0003-4269-8366 walvoord@usgs.gov","orcid":"https://orcid.org/0000-0003-4269-8366","contributorId":147211,"corporation":false,"usgs":true,"family":"Walvoord","given":"Michelle","email":"walvoord@usgs.gov","middleInitial":"Ann","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"preferred":true,"id":468266,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rose, J.R.","contributorId":80137,"corporation":false,"usgs":true,"family":"Rose","given":"J.R.","email":"","affiliations":[],"preferred":false,"id":468264,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Minsley, B.

Stream temperature maxima (Tmax_w) and stream flow minima (Qmin) can create periods of stress for aquatic organisms. In mountainous areas, such as western North America, recent shifts toward an earlier spring peak flow and decreases in low flow during summer/fall have been reported. We hypothesized that an earlier peak flow could be shifting the timing of low flow and leading to a decrease in the interval between Tmax_w and Qmin. We also examined if years with extreme low Qmin were associated with years of extreme high Tmax_w. We tested these hypotheses using long32 term data from 22 minimally human-influenced streams for the period 1950-2010. We found trends toward a shorter time lag between Tmax_w and Qmin over time and a strong negative association between their magnitudes. Our findings show that aquatic biota may be increasingly experiencing narrower time windows to recover or adapt between these extreme events of low flow and high temperature. This study highlights the importance of evaluating multiple environmental drivers to better gauge the effects of the recent climate variability in freshwaters.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hydrobiologia","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","publisherLocation":"Amsterdam, Netherlands","doi":"10.1007/s10750-012-1327-2","usgsCitation":"Arismendi, I., Safeeq, M., Johnson, S.L., Dunham, J., and Haggerty, R., 2013, Increasing synchrony of high temperature and low flow in western North American streams: double trouble for coldwater biota?: Hydrobiologia, v. 712, no. 1, p. 61-70, https://doi.org/10.1007/s10750-012-1327-2.","productDescription":"10 p.","startPage":"61","endPage":"70","numberOfPages":"10","additionalOnlineFiles":"N","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":262686,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":262684,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10750-012-1327-2","linkFileType":{"id":5,"text":"html"}}],"otherGeospatial":"North America","volume":"712","issue":"1","noUsgsAuthors":false,"publicationDate":"2012-09-21","publicationStatus":"PW","scienceBaseUri":"50801866e4b0a0242ef285c1","contributors":{"authors":[{"text":"Arismendi, Ivan","contributorId":70661,"corporation":false,"usgs":true,"family":"Arismendi","given":"Ivan","affiliations":[],"preferred":false,"id":468134,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Safeeq, Mohammad 0000-0003-0529-3925","orcid":"https://orcid.org/0000-0003-0529-3925","contributorId":77814,"corporation":false,"usgs":false,"family":"Safeeq","given":"Mohammad","email":"","affiliations":[{"id":6641,"text":"University of California at Merced","active":true,"usgs":false}],"preferred":false,"id":468135,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Johnson, Sherri L.","contributorId":91757,"corporation":false,"usgs":true,"family":"Johnson","given":"Sherri","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":468136,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dunham, Jason B.","contributorId":64791,"corporation":false,"usgs":true,"family":"Dunham","given":"Jason B.","affiliations":[],"preferred":false,"id":468133,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Haggerty, Roy","contributorId":102631,"corporation":false,"usgs":true,"family":"Haggerty","given":"Roy","affiliations":[],"preferred":false,"id":468137,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}} ,{"id":70038893,"text":"70038893 - 2013 - Ecology of zoonotic infectious diseases in bats: current knowledge and future directions","interactions":[],"lastModifiedDate":"2016-12-14T11:23:57","indexId":"70038893","displayToPublicDate":"2012-10-08T00:00:00","publicationYear":"2013","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3813,"text":"Zoonoses and Public Health","active":true,"publicationSubtype":{"id":10}},"title":"Ecology of zoonotic infectious diseases in bats: current knowledge and future directions","docAbstract":"Bats are hosts to a range of zoonotic and potentially zoonotic pathogens. Human activities that increase exposure to bats will likely increase the opportunity for infections to spill over in the future. Ecological drivers of pathogen spillover and emergence in novel hosts, including humans, involve a complex mixture of processes, and understanding these complexities may aid in predicting spillover. In particular, only once the pathogen and host ecologies are known can the impacts of anthropogenic changes be fully appreciated. Cross-disciplinary approaches are required to understand how host and pathogen ecology interact. Bats differ from other sylvatic disease reservoirs because of their unique and diverse lifestyles, including their ability to fly, often highly gregarious social structures, long lifespans and low fecundity rates. We highlight how these traits may affect infection dynamics and how both host and pathogen traits may interact to affect infection dynamics. We identify key questions relating to the ecology of infectious diseases in bats and propose that a combination of field and laboratory studies are needed to create data-driven mechanistic models to elucidate those aspects of bat ecology that are most critical to the dynamics of emerging bat viruses. If commonalities can be found, then predicting the dynamics of newly emerging diseases may be possible. This modelling approach will be particularly important in scenarios when population surveillance data are unavailable and when it is unclear which aspects of host ecology are driving infection dynamics.","language":"English","publisher":"Blackwell Verlag","doi":"10.1111/zph.12000","usgsCitation":"Hayman, D., Bowen, R.A., Cryan, P., McCracken, G., O'Shea, T., Peel, A., Gilbert, A., Webb, C., and Wood, J., 2013, Ecology of zoonotic infectious diseases in bats: current knowledge and future directions: Zoonoses and Public Health, v. 60, no. 1, p. 2-21, https://doi.org/10.1111/zph.12000.","productDescription":"20 p.","startPage":"2","endPage":"21","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":474068,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/zph.12000","text":"Publisher Index Page"},{"id":262452,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":262451,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/zph.12000"}],"volume":"60","issue":"1","noUsgsAuthors":false,"publicationDate":"2012-09-07","publicationStatus":"PW","scienceBaseUri":"50744f88e4b090654e7b2640","contributors":{"authors":[{"text":"Hayman, D.T.","contributorId":46816,"corporation":false,"usgs":true,"family":"Hayman","given":"D.T.","email":"","affiliations":[],"preferred":false,"id":465185,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bowen, R.

Understanding the environmental factors that regulate fish recruitment is essential for effective management of fisheries. Generally, first-year survival, and therefore recruitment, is inherently less consistent in systems with high intra- and interannual variability. Irrigation reservoirs display sporadic patterns of annual drawdown, which can pose a substantial challenge to recruitment of fishes. We developed species-specific models using an 18-year data set compiled from state and federal agencies to investigate variables that regulate the recruitment of walleye Sander vitreus and white bass Morone chrysops in irrigation reservoirs in south-west Nebraska, USA. The candidate model set for walleye included only abiotic variables (water-level elevation, minimum daily air temperature during winter prior to hatching, annual precipitation, spring warming rate and May reservoir discharge), and the candidate model set for white bass included primarily biotic variables (catch per unit effort (CPUE) of black crappie Pomoxis nigromaculatus, CPUE of age-0 walleye, CPUE of bluegill Lepomis macrochirus and CPUE of age-3 and older white bass), each of which had a greater relative importance than the single abiotic variable (minimum daily air temperature during winter after hatching). Our findings improve the understanding of the recruitment of fishes in irrigation reservoirs and the relative roles of abiotic and biotic factors.

Both of these events resulted in surprisingly high death tolls, casualties and survivors made homeless. In the Mw = 7.0 Haiti earthquake, over 200,000 people perished with more than 300,000 reported injuries and 2 million made homeless. The Mw = 6.9 earthquake in Qinghai resulted in over 2,000 deaths with a further 11,000 people with serious or moderate injuries and 100,000 people have been left homeless in this mountainous region of China. In such events relief efforts can be significantly benefitted by the availability of rapid estimation and mapping of expected casualties. This paper contributes to ongoing global efforts to estimate probable earthquake casualties very rapidly after an earthquake has taken place. The analysis uses the assembled empirical damage and casualty data in the Cambridge Earthquake Impacts Database (CEQID) and explores data by event and across events to test the relationships of building and fatality distributions to the main explanatory variables of building type, building damage level and earthquake intensity. The prototype global casualty estimation model described here uses a semi-empirical approach that estimates damage rates for different classes of buildings present in the local building stock, and then relates fatality rates to the damage rates of each class of buildings. This approach accounts for the effect of the very different types of buildings (by climatic zone, urban or rural location, culture, income level etc), on casualties. The resulting casualty parameters were tested against the overall casualty data from several historical earthquakes in CEQID; a reasonable fit was found.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of Earthquake Engineering","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","publisherLocation":"Amsterdam, Netherlands","doi":"10.1007/s10518-012-9373-8","usgsCitation":"So, E., and Spence, R., 2013, Estimating shaking-induced casualties and building damage for global earthquake events: a proposed modelling approach: Bulletin of Earthquake Engineering, v. 11, no. 1, p. 347-363, https://doi.org/10.1007/s10518-012-9373-8.","productDescription":"17 p.","startPage":"347","endPage":"363","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":262462,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":262460,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10518-012-9373-8"}],"volume":"11","issue":"1","noUsgsAuthors":false,"publicationDate":"2012-08-30","publicationStatus":"PW","scienceBaseUri":"50744fa2e4b090654e7b264c","contributors":{"authors":[{"text":"So, Emily","contributorId":19420,"corporation":false,"usgs":true,"family":"So","given":"Emily","email":"","affiliations":[],"preferred":false,"id":350508,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Spence, Robin","contributorId":97366,"corporation":false,"usgs":true,"family":"Spence","given":"Robin","affiliations":[],"preferred":false,"id":350509,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70039843,"text":"70039843 - 2013 - Effects of linking a soil-water-balance model with a groundwater-flow model","interactions":[],"lastModifiedDate":"2013-07-15T08:57:37","indexId":"70039843","displayToPublicDate":"2012-10-08T00:00:00","publicationYear":"2013","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1862,"text":"Ground Water Journal","active":true,"publicationSubtype":{"id":10}},"title":"Effects of linking a soil-water-balance model with a groundwater-flow model","docAbstract":"A previously published regional groundwater-flow model in north-central Nebraska was sequentially linked with the recently developed soil-water-balance (SWB) model to analyze effects to groundwater-flow model parameters and calibration results. The linked models provided a more detailed spatial and temporal distribution of simulated recharge based on hydrologic processes, improvement of simulated groundwater-level changes and base flows at specific sites in agricultural areas, and a physically based assessment of the relative magnitude of recharge for grassland, nonirrigated cropland, and irrigated cropland areas. Root-mean-squared (RMS) differences between the simulated and estimated or measured target values for the previously published model and linked models were relatively similar and did not improve for all types of calibration targets. However, without any adjustment to the SWB-generated recharge, the RMS difference between simulated and estimated base-flow target values for the groundwater-flow model was slightly smaller than for the previously published model, possibly indicating that the volume of recharge simulated by the SWB code was closer to actual hydrogeologic conditions than the previously published model provided. Groundwater-level and base-flow hydrographs showed that temporal patterns of simulated groundwater levels and base flows were more accurate for the linked models than for the previously published model at several sites, particularly in agricultural areas.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ground Water Journal","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1111/j.1745-6584.2012.01000.x","usgsCitation":"Stanton, J.S., Ryter, D.W., and Peterson, S.M., 2013, Effects of linking a soil-water-balance model with a groundwater-flow model: Ground Water Journal, v. 51, no. 4, p. 613-622, https://doi.org/10.1111/j.1745-6584.2012.01000.x.","productDescription":"10 p.","startPage":"613","endPage":"622","costCenters":[{"id":464,"text":"Nebraska Water Science Center","active":true,"usgs":true}],"links":[{"id":262464,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":262455,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1745-6584.2012.01000.x"}],"country":"United States","state":"Nebraska","volume":"51","issue":"4","noUsgsAuthors":false,"publicationDate":"2012-10-04","publicationStatus":"PW","scienceBaseUri":"50744f90e4b090654e7b2644","contributors":{"authors":[{"text":"Stanton, Jennifer S. 0000-0002-2520-753X jstanton@usgs.gov","orcid":"https://orcid.org/0000-0002-2520-753X","contributorId":830,"corporation":false,"usgs":true,"family":"Stanton","given":"Jennifer","email":"jstanton@usgs.gov","middleInitial":"S.","affiliations":[{"id":464,"text":"Nebraska Water Science Center","active":true,"usgs":true},{"id":376,"text":"Massachusetts Water Science Center","active":true,"usgs":true},{"id":466,"text":"New England Water Science Center","active":true,"usgs":true}],"preferred":true,"id":467036,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ryter, Derek W. 0000-0002-2488-626X dryter@usgs.gov","orcid":"https://orcid.org/0000-0002-2488-626X","contributorId":3395,"corporation":false,"usgs":true,"family":"Ryter","given":"Derek","email":"dryter@usgs.gov","middleInitial":"W.","affiliations":[{"id":516,"text":"Oklahoma Water Science Center","active":true,"usgs":true},{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":467038,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Peterson, Steven M. 0000-0002-9130-1284 speterson@usgs.gov","orcid":"https://orcid.org/0000-0002-9130-1284","contributorId":847,"corporation":false,"usgs":true,"family":"Peterson","given":"Steven","email":"speterson@usgs.gov","middleInitial":"M.","affiliations":[{"id":464,"text":"Nebraska Water Science Center","active":true,"usgs":true}],"preferred":true,"id":467037,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":70039961,"text":"70039961 - 2013 - Using variance components to estimate power in a hierarchically nested sampling design improving monitoring of larval Devils Hole pupfish","interactions":[],"lastModifiedDate":"2013-02-07T18:18:41","indexId":"70039961","displayToPublicDate":"2012-10-06T00:00:00","publicationYear":"2013","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3103,"text":"Population Ecology","active":true,"publicationSubtype":{"id":10}},"title":"Using variance components to estimate power in a hierarchically nested sampling design improving monitoring of larval Devils Hole pupfish","docAbstract":"We used variance components to assess allocation of sampling effort in a hierarchically nested sampling design for ongoing monitoring of early life history stages of the federally endangered Devils Hole pupfish (DHP) (Cyprinodon diabolis).

Salt Creek is fed by an underground spring and is comprised of numerous pools, runs, and marshes that exhibit substantial variability in temperature, salinity, and dissolved oxygen concentrations. In addition, the wetted area of Salt Creek is reduced throughout the summer months due to high rates of evaporation, with some reaches drying completely. Therefore, it seems logical that short- and long-term movement patterns may play an important role in Salt Creek pupfish population dynamics. The objective of this study was to describe coarse-scale movements of Salt Creek pupfish in Salt Creek during their breeding season from March to May. Sex ratios and length–frequency distributions varied spatially within Salt Creek, suggesting population segregation during the breeding season. Long-distance movements were generally rare, although two fish moved more than 1.2 km. Movement in upstream reaches was rare or absent, in contrast to the greater movement observed in downstream reaches (29% of recaptures). Temporal trends and demographic patterns in movement were not observed. Because the two most downstream habitats dry up in the summer, our results indicate that coarse-scale movements that re-populate downstream reaches likely occur during other times of year. Consequently, the importance of small- and large-scale movements is influenced by season. Further assessment of Salt Creek movement patterns conducted during other times of year may better illuminate long-distance movement patterns and source-sink dynamics.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Freshwater Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Taylor & Francis","publisherLocation":"Philadelphia, PA","doi":"10.1080/02705060.2012.718250","usgsCitation":"Dzul, M., Quist, M., Dinsmore, S., Gaines, D., and Bower, M., 2013, Coarse-scale movement patterns of a small-bodied fish inhabiting a desert stream: Journal of Freshwater Ecology, v. 28, no. 1, p. 27-38, https://doi.org/10.1080/02705060.2012.718250.","productDescription":"12 p.","startPage":"27","endPage":"38","costCenters":[{"id":342,"text":"Idaho Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":262431,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":262430,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1080/02705060.2012.718250"}],"country":"United States","state":"California","otherGeospatial":"Death Valley;Salt Creek","volume":"28","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50788c2ee4b0cfc2d59f5a13","contributors":{"authors":[{"text":"Dzul, M.C.","contributorId":48839,"corporation":false,"usgs":true,"family":"Dzul","given":"M.C.","affiliations":[],"preferred":false,"id":465231,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Quist, M.C. 0000-0001-8268-1839","orcid":"https://orcid.org/0000-0001-8268-1839","contributorId":62805,"corporation":false,"usgs":true,"family":"Quist","given":"M.C.","affiliations":[],"preferred":false,"id":465232,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dinsmore, S.J.","contributorId":85114,"corporation":false,"usgs":true,"family":"Dinsmore","given":"S.J.","email":"","affiliations":[],"preferred":false,"id":465233,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gaines, D.B.","contributorId":96166,"corporation":false,"usgs":true,"family":"Gaines","given":"D.B.","email":"","affiliations":[],"preferred":false,"id":465234,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Bower, M.R.","contributorId":14094,"corporation":false,"usgs":true,"family":"Bower","given":"M.R.","email":"","affiliations":[],"preferred":false,"id":465230,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}} ,{"id":70040116,"text":"70040116 - 2013 - Trends and shifts in streamflow in Hawaii, 1913-2008","interactions":[],"lastModifiedDate":"2013-05-06T09:55:48","indexId":"70040116","displayToPublicDate":"2012-10-02T00:00:00","publicationYear":"2013","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1924,"text":"Hydrological Processes","active":true,"publicationSubtype":{"id":10}},"title":"Trends and shifts in streamflow in Hawaii, 1913-2008","docAbstract":"This study addresses a need to document changes in streamflow and base flow (groundwater discharge to streams) in Hawai'i during the past century. Statistically significant long-term (1913-2008) downward trends were detected (using the nonparametric Mann-Kendall test) in low-streamflow and base-flow records. These long-term downward trends are likely related to a statistically significant downward shift around 1943 detected (using the nonparametric Pettitt test) in index records of streamflow and base flow. The downward shift corresponds to a decrease of 22% in median streamflow and a decrease of 23% in median base flow between the periods 1913-1943 and 1943-2008. The shift coincides with other local and regional factors, including a change from a positive to a negative phase in the Pacific Decadal Oscillation, shifts in the direction of the trade winds over Hawai'i, and a reforestation programme. The detected shift and long-term trends reflect region-wide changes in climatic and land-cover factors. A weak pattern of downward trends in base flows during the period 1943-2008 may indicate a continued decrease in base flows after the 1943 shift. Downward trends were detected more commonly in base-flow records than in high-streamflow, peak-flow, and rainfall records. The decrease in base flow is likely related to a decrease in groundwater storage and recharge and therefore is a valuable indicator of decreasing water availability and watershed vulnerability to hydrologic changes. Whether the downward trends will continue is largely uncertain given the uncertainty in climate-change projections and watershed responses to changes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hydrological Processes","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"John Wiley & Sons","doi":"10.1002/hyp.9298","usgsCitation":"Bassiouni, M., and Oki, D.S., 2013, Trends and shifts in streamflow in Hawaii, 1913-2008: Hydrological Processes, v. 27, no. 10, p. 1484-1500, https://doi.org/10.1002/hyp.9298.","productDescription":"17 p.","startPage":"1484","endPage":"1500","costCenters":[{"id":525,"text":"Pacific Islands Water Science Center","active":true,"usgs":true}],"links":[{"id":474070,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"http://infoscience.epfl.ch/record/189096","text":"Publisher Index Page"},{"id":262187,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":262184,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/hyp.9298"}],"country":"United States","state":"Hawai'i","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -162,16.916666666666668 ], [ -162,23 ], [ -154.66666666666666,23 ], [ -154.66666666666666,16.916666666666668 ], [ -162,16.916666666666668 ] ] ] } } ] }","volume":"27","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"506c0202e4b05073318eeadc","contributors":{"authors":[{"text":"Bassiouni, Maoya 0000-0001-5795-9894 mbassiou@usgs.gov","orcid":"https://orcid.org/0000-0001-5795-9894","contributorId":4639,"corporation":false,"usgs":true,"family":"Bassiouni","given":"Maoya","email":"mbassiou@usgs.gov","affiliations":[{"id":525,"text":"Pacific Islands Water Science Center","active":true,"usgs":true}],"preferred":false,"id":467741,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Oki, Delwyn S. 0000-0002-6913-8804 dsoki@usgs.gov","orcid":"https://orcid.org/0000-0002-6913-8804","contributorId":1901,"corporation":false,"usgs":true,"family":"Oki","given":"Delwyn","email":"dsoki@usgs.gov","middleInitial":"S.","affiliations":[{"id":525,"text":"Pacific Islands Water Science Center","active":true,"usgs":true}],"preferred":true,"id":467740,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70040103,"text":"70040103 - 2013 - An 80-year record of sediment quality in the lower Mississippi River","interactions":[],"lastModifiedDate":"2013-07-29T08:40:44","indexId":"70040103","displayToPublicDate":"2012-09-28T00:00:00","publicationYear":"2013","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1924,"text":"Hydrological Processes","active":true,"publicationSubtype":{"id":10}},"title":"An 80-year record of sediment quality in the lower Mississippi River","docAbstract":"In 1937, the US Army Corps of Engineers cut through the \"neck\" of a large meander on the lower Mississippi River (below the confluence with the Ohio River) forming the Caulk Neck cutoff and creating Lake Whittington, a 26-km long oxbow lake, in northern Mississippi. Since 1938, seasonal flooding and a boat channel connecting the lake with the Mississippi River have led to sediment accumulation in the lake, resulting in an 80-year record of sediment quality in the river. On the basis of an age-dated sediment core from the lake, trends in trace metals and hydrophobic organic compounds (except polycyclic aromatic hydrocarbons) follow well-known patterns with upward trends from the 1930s to the ca 1970s, followed by downward trends to the present. Two factors contribute to these patterns: reservoir construction and changes in emissions. The construction of seven large reservoirs on the Missouri River, in particular the closure of the Fort Randall (1953) and Gavins Point (1955) Dams, greatly reduced the load of relatively clean sediment to the Mississippi River, likely contributing to downstream increases in contaminant concentrations in the Mississippi River. Increasing anthropogenic emissions also contributed to upward trends until ca 1970 when major environmental policy actions began resulting in broad decreases in emissions and downward trends in the concentrations of most of the contaminants monitored. Polycyclic aromatic hydrocarbons and phosphorus are partial exceptions to this pattern, with increases to the 1960s and variable concentrations showing no clear trend since. Published 2012.

Concern exists that pesticide and nutrient runoff from surrounding row-crops enters wetlands degrading water quality and adversely affecting birds and wildlife. Frogs may be especially vulnerable. Plains leopard (Lithobates blairi) metamorphs from RWB wetlands with varying concentrations of pesticides were evaluated for a suite of biomarkers of exposure to endocrine active chemicals. Froglets had ovarian dysgenesis, high rates of testicular oocytes, and female-biased sex ratios however, there was no clear statistical association between pesticide concentrations and biomarkers. Data interpretation was hindered because timing and duration of exposures were unknown and due to an incomplete understanding of L. blairi sexual development. Emphasis is on describing the complex developmental biology of closely-related leopard frogs, how this understanding can explain RWB L. blairi anomalies, and the need for sampling at the appropriate life stage.","language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam.

Combining results of this and a previously published multi-basin study, fish Hg correlated strongly with sampled water FMeHg concentration (p = 0.78; p = 0.003) and annual FMeHg basin yield (p = 0.66; p = 0.026). Improved correlation (p = 0.88; p < 0.0001) was achieved with time-weighted mean annual FMeHg concentrations estimated from basin-specific LOADEST models and daily streamflow.

To assess the effects of fire on surface topography, soil roughness, and vegetation, we used terrestrial (ground-based) LiDAR to quantify the differences between burned and unburned surfaces by creating a series of high-resolution vegetation structure and bare-earth surface models for six sample plots in the Grand Canyon-Parashant National Monument, Arizona. We find that 11 years following prescribed burns, mound volumes, plant heights, and soil-surface roughness were significantly lower on burned relative to unburned plots. Results also suggest a linkage between vegetation and soil mounds, either through accretion or erosion mechanisms such as wind and/or water erosion. The biogeomorphic implications of fire-induced changes are significant. Reduced plant cover and altered soil surfaces from fire likely influence seed residence times, inhibit seed germination and plant establishment, and affect other ecohydrological processes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Earth Surface Processes and Landforms","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","publisherLocation":"Hoboken, NJ","doi":"10.1002/esp.3264","usgsCitation":"Soulard, C.E., Esque, T., Bedford, D., and Bond, S., 2013, The role of fire on soil mounds and surface roughness in the Mojave Desert: Earth Surface Processes and Landforms, v. 38, no. 2, p. 111-121, https://doi.org/10.1002/esp.3264.","productDescription":"11 p.","startPage":"111","endPage":"121","costCenters":[{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"links":[{"id":260110,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":260107,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/esp.3264","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Arizona","otherGeospatial":"Mojave Desert","volume":"38","issue":"2","noUsgsAuthors":false,"publicationDate":"2012-05-20","publicationStatus":"PW","scienceBaseUri":"505baf70e4b08c986b3247c5","contributors":{"authors":[{"text":"Soulard, Christopher E. 0000-0002-5777-9516 csoulard@usgs.gov","orcid":"https://orcid.org/0000-0002-5777-9516","contributorId":2642,"corporation":false,"usgs":true,"family":"Soulard","given":"Christopher","email":"csoulard@usgs.gov","middleInitial":"E.","affiliations":[{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"preferred":true,"id":466924,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Esque, Todd C. tesque@usgs.gov","contributorId":3221,"corporation":false,"usgs":true,"family":"Esque","given":"Todd C.","email":"tesque@usgs.gov","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":false,"id":466925,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bedford, David R.","contributorId":26352,"corporation":false,"usgs":true,"family":"Bedford","given":"David R.","affiliations":[],"preferred":false,"id":466927,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bond, Sandra 0000-0003-0522-5287 sbond@usgs.gov","orcid":"https://orcid.org/0000-0003-0522-5287","contributorId":3328,"corporation":false,"usgs":true,"family":"Bond","given":"Sandra","email":"sbond@usgs.gov","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":466926,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70039516,"text":"70039516 - 2013 - Successional stage of biological soil crusts: an accurate indicator of ecohydrological condition","interactions":[],"lastModifiedDate":"2013-06-17T08:47:43","indexId":"70039516","displayToPublicDate":"2012-08-09T00:00:00","publicationYear":"2013","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1447,"text":"Ecohydrology","active":true,"publicationSubtype":{"id":10}},"title":"Successional stage of biological soil crusts: an accurate indicator of ecohydrological condition","docAbstract":"Biological soil crusts are a key component of many dryland ecosystems. Following disturbance, biological soil crusts will recover in stages. Recently, a simple classification of these stages has been developed, largely on the basis of external features of the crusts, which reflects their level of development (LOD). The classification system has six LOD classes, from low (1) to high (6). To determine whether the LOD of a crust is related to its ecohydrological function, we used rainfall simulation to evaluate differences in infiltration, runoff, and erosion among crusts in the various LODs, across a range of soil depths and with different wetting pre-treatments. We found large differences between the lowest and highest LODs, with runoff and erosion being greatest from the lowest LOD. Under dry antecedent conditions, about 50% of the water applied ran off the lowest LOD plots, whereas less than 10% ran off the plots of the two highest LODs. Similarly, sediment loss was 400 g m-2 from the lowest LOD and almost zero from the higher LODs. We scaled up the results from these simulations using the Rangeland Hydrology and Erosion Model. Modelling results indicate that erosion increases dramatically as slope length and gradient increase, especially beyond the threshold values of 10 m for slope length and 10% for slope gradient. Our findings confirm that the LOD classification is a quick, easy, nondestructive, and accurate index of hydrological condition and should be incorporated in field and modelling assessments of ecosystem health.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecohydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"John Wiley and Sons, Ltd.","doi":"10.1002/eco.1281","usgsCitation":"Belnap, J., Wilcox, B.P., Van Scoyoc, M.V., and Phillips, S.L., 2013, Successional stage of biological soil crusts: an accurate indicator of ecohydrological condition: Ecohydrology, v. 6, no. 3, p. 474-482, https://doi.org/10.1002/eco.1281.","productDescription":"9 p.","startPage":"474","endPage":"482","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":259527,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":259524,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/eco.1281","linkFileType":{"id":5,"text":"html"}}],"volume":"6","issue":"3","noUsgsAuthors":false,"publicationDate":"2012-06-11","publicationStatus":"PW","scienceBaseUri":"505b9da9e4b08c986b31d9b4","contributors":{"authors":[{"text":"Belnap, Jayne 0000-0001-7471-2279 jayne_belnap@usgs.gov","orcid":"https://orcid.org/0000-0001-7471-2279","contributorId":1332,"corporation":false,"usgs":true,"family":"Belnap","given":"Jayne","email":"jayne_belnap@usgs.gov","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":466401,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wilcox, Bradford P.","contributorId":55298,"corporation":false,"usgs":true,"family":"Wilcox","given":"Bradford","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":466403,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Van Scoyoc, Matthew V.","contributorId":24651,"corporation":false,"usgs":true,"family":"Van Scoyoc","given":"Matthew","email":"","middleInitial":"V.","affiliations":[],"preferred":false,"id":466402,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Phillips, Susan L.","contributorId":59285,"corporation":false,"usgs":true,"family":"Phillips","given":"Susan","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":466404,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70038464,"text":"70038464 - 2013 - Toxicity of sediment pore water in Puget Sound (Washington, USA): a review of spatial status and temporal trends","interactions":[],"lastModifiedDate":"2016-12-18T17:34:01","indexId":"70038464","displayToPublicDate":"2012-08-01T00:00:00","publicationYear":"2013","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1552,"text":"Environmental Monitoring and Assessment","onlineIssn":"1573-2959","printIssn":"0167-6369","active":true,"publicationSubtype":{"id":10}},"title":"Toxicity of sediment pore water in Puget Sound (Washington, USA): a review of spatial status and temporal trends","docAbstract":"Data from toxicity tests of the pore water extracted from Puget Sound sediments were compiled from surveys conducted from 1997 to 2009. Tests were performed on 664 samples collected throughout all of the eight monitoring regions in the Sound, an area encompassing 2,294.1 km2. Tests were performed with the gametes of the Pacific purple sea urchin, Strongylocentrotus purpuratus, to measure percent fertilization success as an indicator of relative sediment quality. Data were evaluated to determine the incidence, degree of response, geographic patterns, spatial extent, and temporal changes in toxicity. This is the first survey of this kind and magnitude in Puget Sound. In the initial round of surveys of the eight regions, 40 of 381 samples were toxic for an incidence of 10.5 %. Stations classified as toxic represented an estimated total of 107.1 km2, equivalent to 4.7 % of the total area. Percent sea urchin fertilization ranged from >100 % of the nontoxic, negative controls to 0 %. Toxicity was most prevalent and pervasive in the industrialized harbors and lowest in the deep basins. Conditions were intermediate in deep-water passages, urban bays, and rural bays. A second round of testing in four regions and three selected urban bays was completed 5–10 years following the first round. The incidence and spatial extent of toxicity decreased in two of the regions and two of the bays and increased in the other two regions and the third bay; however, only the latter change was statistically significant. Both the incidence and spatial extent of toxicity were lower in the Sound than in most other US estuaries and marine bays.","language":"English","publisher":"Springer Netherlands","publisherLocation":"Amsterdam, Netherlands","doi":"10.1007/s10661-012-2590-4","usgsCitation":"Long, E.R., Carr, R.S., Biedenbach, J.M., Weakland, S., Partridge, V., and Dutch, M., 2013, Toxicity of sediment pore water in Puget Sound (Washington, USA): a review of spatial status and temporal trends: Environmental Monitoring and Assessment, v. 185, no. 1, p. 755-775, https://doi.org/10.1007/s10661-012-2590-4.","productDescription":"21 p.","startPage":"755","endPage":"775","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":259402,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Washington","otherGeospatial":"Puget Sound","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -125.3759765625,\n 46.965259400349275\n ],\n [\n -125.3759765625,\n 49.13859653703879\n ],\n [\n -121.81640624999999,\n 49.13859653703879\n ],\n [\n -121.81640624999999,\n 46.965259400349275\n ],\n [\n -125.3759765625,\n 46.965259400349275\n ]\n ]\n ]\n }\n }\n ]\n}","volume":"185","issue":"1","noUsgsAuthors":false,"publicationDate":"2012-03-06","publicationStatus":"PW","scienceBaseUri":"505bb612e4b08c986b326a47","contributors":{"authors":[{"text":"Long, Edward R.","contributorId":106365,"corporation":false,"usgs":true,"family":"Long","given":"Edward","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":464284,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Carr, R.

Previous studies have shown that hatchery-origin Chinook salmon (Oncorhynchus tshawytscha) released from different acclimation sites return with varying degrees of fidelity to these areas. To investigate the possibility that homing fidelity is associated with aquatic habitat conditions, we quantified physical habitat throughout 165 km in the upper Yakima River basin (Washington, USA) and mapped redd and carcass locations from 2004 to 2008. Principal components analysis identified differences in substrate, cover, stream width, and gradient among reaches surrounding acclimation sites, and canonical correspondence analysis revealed that these differences in habitat characteristics were associated with spatial patterns of spawning (p < 0.01). These analyses indicated that female salmon may forego spawning near their acclimation area if the surrounding habitat is unsuitable. Evaluating the spatial context of acclimation areas in relation to surrounding habitat may provide essential information for effectively managing supplementation programs and prioritizing restoration actions.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Biology of Fishes","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","publisherLocation":"Amsterdam, Netherlands","doi":"10.1007/s10641-012-0026-1","usgsCitation":"Cram, J., Torgersen, C., Klett, R., Pess, G.R., May, D., Pearsons, T., and Dittman, A., 2013, Tradeoffs between homing and habitat quality for spawning site selection by hatchery-origin Chinook salmon: Environmental Biology of Fishes, v. 96, no. 1, p. 109-122, https://doi.org/10.1007/s10641-012-0026-1.","productDescription":"14 p.","startPage":"109","endPage":"122","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":259405,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":259388,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10641-012-0026-1","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Washington","otherGeospatial":"Yakima River","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -121.450093,46.793577 ], [ -121.450093,47.538786 ], [ -119.991264,47.538786 ], [ -119.991264,46.793577 ], [ -121.450093,46.793577 ] ] ] } } ] }","volume":"96","issue":"1","noUsgsAuthors":false,"publicationDate":"2012-05-01","publicationStatus":"PW","scienceBaseUri":"505bb6afe4b08c986b326dff","contributors":{"authors":[{"text":"Cram, Jeremy M.","contributorId":11898,"corporation":false,"usgs":true,"family":"Cram","given":"Jeremy M.","affiliations":[],"preferred":false,"id":464442,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Torgersen, Christian E. 0000-0001-8325-2737","orcid":"https://orcid.org/0000-0001-8325-2737","contributorId":48143,"corporation":false,"usgs":true,"family":"Torgersen","given":"Christian E.","affiliations":[],"preferred":false,"id":464446,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Klett, Ryan S.","contributorId":26938,"corporation":false,"usgs":true,"family":"Klett","given":"Ryan S.","affiliations":[],"preferred":false,"id":464444,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Pess, George R.","contributorId":13501,"corporation":false,"usgs":false,"family":"Pess","given":"George","email":"","middleInitial":"R.","affiliations":[{"id":6578,"text":"National Marine Fisheries Service, Seattle, WA 98112, USA","active":true,"usgs":false}],"preferred":false,"id":464443,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"May, Darran","contributorId":90991,"corporation":false,"usgs":true,"family":"May","given":"Darran","affiliations":[],"preferred":false,"id":464447,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Pearsons, Todd N.","contributorId":95345,"corporation":false,"usgs":true,"family":"Pearsons","given":"Todd N.","affiliations":[],"preferred":false,"id":464448,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Dittman, Andrew H.","contributorId":40482,"corporation":false,"usgs":true,"family":"Dittman","given":"Andrew H.","affiliations":[],"preferred":false,"id":464445,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}} ,{"id":70003725,"text":"70003725 - 2013 - Shovelnose sturgeon spawning in relation to varying discharge treatments in a Missouri River tributary","interactions":[],"lastModifiedDate":"2013-10-23T08:33:19","indexId":"70003725","displayToPublicDate":"2012-08-01T00:00:00","publicationYear":"2013","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3301,"text":"River Research and Applications","active":true,"publicationSubtype":{"id":10}},"title":"Shovelnose sturgeon spawning in relation to varying discharge treatments in a Missouri River tributary","docAbstract":"Many lotic fish species use natural patterns of variation in discharge and temperature as spawning cues, and these natural patterns are often altered by river regulation. The effects of spring discharge and water temperature variation on the spawning of shovelnose sturgeon Scaphirhynchus platorynchus have not been well documented. From 2006 through 2009, we had the opportunity to study the effects of experimental discharge levels on shovelnose sturgeon spawning in the lower Marias River, a regulated tributary to the Missouri River in Montana. In 2006, shovelnose sturgeon spawned in the Marias River in conjunction with the ascending, peak (134 m3/s) and descending portions of the spring hydrograph and water temperatures from 16°C to 19°C. In 2008, shovelnose sturgeon spawned in conjunction with the peak (118 m3/s) and descending portions of the spring hydrograph and during a prolonged period of increased discharge (28–39 m3/s), coupled with water temperatures from 11°C to 23°C in the lower Marias River. No evidence of shovelnose sturgeon spawning was documented in the lower Marias River in 2007 or 2009 when discharge remained low (14 and 20 m3/s) despite water temperatures suitable and optimal (12°C-24°C) for shovelnose sturgeon embryo development. A similar relationship between shovelnose sturgeon spawning and discharge was observed in the Teton River. These data suggest that discharge must reach a threshold level (28 m3/s) and should be coupled with water temperatures suitable (12°C-24°C) or optimal (16°C-20°C) for shovelnose sturgeon embryo development to provide a spawning cue for shovelnose sturgeon in the lower Marias River.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"River Research and Applications","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"John Wiley & Sons, Ltd.","publisherLocation":"Hoboken, NJ","doi":"10.1002/rra.2587","usgsCitation":"Goodman, B., Guy, C., Camp, S., Gardner, W., Kappenman, K., and Webb, M., 2013, Shovelnose sturgeon spawning in relation to varying discharge treatments in a Missouri River tributary: River Research and Applications, v. 29, no. 8, p. 1004-1015, https://doi.org/10.1002/rra.2587.","productDescription":"12 p.","startPage":"1004","endPage":"1015","costCenters":[{"id":398,"text":"Montana Cooperative Fishery Research Unit","active":false,"usgs":true}],"links":[{"id":259392,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":259379,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/rra.2587","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Montana","otherGeospatial":"Marias River","volume":"29","issue":"8","noUsgsAuthors":false,"publicationDate":"2012-06-18","publicationStatus":"PW","scienceBaseUri":"505b8ee8e4b08c986b318c06","contributors":{"authors":[{"text":"Goodman, B.J.","contributorId":25813,"corporation":false,"usgs":true,"family":"Goodman","given":"B.J.","email":"","affiliations":[],"preferred":false,"id":348541,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Guy, C.S.","contributorId":59160,"corporation":false,"usgs":true,"family":"Guy","given":"C.S.","email":"","affiliations":[],"preferred":false,"id":348542,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Camp, S.L.","contributorId":93320,"corporation":false,"usgs":true,"family":"Camp","given":"S.L.","email":"","affiliations":[],"preferred":false,"id":348543,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gardner, W.M.","contributorId":7817,"corporation":false,"usgs":true,"family":"Gardner","given":"W.M.","email":"","affiliations":[],"preferred":false,"id":348539,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Kappenman, K.M.","contributorId":13412,"corporation":false,"usgs":true,"family":"Kappenman","given":"K.M.","affiliations":[],"preferred":false,"id":348540,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Webb, M.A.H.","contributorId":102241,"corporation":false,"usgs":true,"family":"Webb","given":"M.A.H.","affiliations":[],"preferred":false,"id":348544,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}} ,{"id":70038517,"text":"70038517 - 2013 - Sediment redistributed by coastal marsh mosquito ditching in Cape May County, New Jersey, U.S.A.","interactions":[],"lastModifiedDate":"2013-02-07T17:52:33","indexId":"70038517","displayToPublicDate":"2012-07-31T00:00:00","publicationYear":"2013","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2220,"text":"Journal of Coastal Research","active":true,"publicationSubtype":{"id":10}},"title":"Sediment redistributed by coastal marsh mosquito ditching in Cape May County, New Jersey, U.S.A.","docAbstract":"Effects of mosquito ditching on salt marsh sediment budgets have not been quantified for lack of sufficient records, but such information is necessary to provide historical context for current management objectives. We were able to do so in Cape May County New Jersey where Mosquito Extermination Commission records reported 1,493,900 m3 of spoil redistributed through ditching from1902 to 1974. The amount of spoil redistributed rose to 2,240,850 m3–22,987,800 m3 overall when ditch cleaning efforts were included. On a 54 km2 study area, 161,560 m of ditches removed as much as 99,000 m3 of material. If all such sediment stayed in the system and was deposited in open water, it would have added 0.082 mm/yr to those areas. If the sediments had accumulated only in the larger water bodies, it would have been sufficient to add 0.16 mm/yr to those areas. Alternatively, if the material had been deposited only on the marsh surface, the material displaced by mosquito ditching was capable of adding only 0.036 mm/yr. These rates are inconsequential in a system infilling at a rate of 4.4–7.4 mm/yr. Materials released by mosquito ditching thus have added to the sediment budgets of this coastal system, but shoaling of bays and sounds in recent centuries is a consequence of increases in all sediment sources including many of anthropogenic origin. Nonetheless, other consequences of ditching to the marsh (e.g., increased drainage, transport of water, and erosion of ditch banks) are not negligible in consideration of all anthropogenic effects. These data can help parameterize models of salt marsh accretion in the face of climate change.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Coastal Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Coastal Education and Research Foundation (CERF)","publisherLocation":"West Palm Beach, FL","doi":"10.2112/JCOASTRES-D-12-00002.1","usgsCitation":"Kirby, R.E., and Widjeskog, L.E., 2013, Sediment redistributed by coastal marsh mosquito ditching in Cape May County, New Jersey, U.S.A.: Journal of Coastal Research, v. 29, no. 1, p. 86-93, https://doi.org/10.2112/JCOASTRES-D-12-00002.1.","productDescription":"8 p.","startPage":"86","endPage":"93","costCenters":[{"id":501,"text":"Office of Science Quality and Integrity","active":true,"usgs":true}],"links":[{"id":259331,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":264113,"type":{"id":15,"text":"Index Page"},"url":"https://jcronline.org/doi/abs/10.2112/JCOASTRES-D-12-00002.1"},{"id":267143,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2112/JCOASTRES-D-12-00002.1"}],"country":"United States","state":"New Jersey","county":"Cape May County","volume":"29","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b89aee4b08c986b316e69","contributors":{"authors":[{"text":"Kirby, Ronald E. ronald_kirby@usgs.gov","contributorId":195,"corporation":false,"usgs":true,"family":"Kirby","given":"Ronald","email":"ronald_kirby@usgs.gov","middleInitial":"E.","affiliations":[],"preferred":true,"id":464495,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Widjeskog, Lee E.","contributorId":85024,"corporation":false,"usgs":true,"family":"Widjeskog","given":"Lee","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":464496,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70004042,"text":"70004042 - 2013 - Predicted macroinvertebrate response to water diversion from a montane stream using two-dimensional hydrodynamic models and zero flow approximation","interactions":[],"lastModifiedDate":"2013-03-04T20:10:55","indexId":"70004042","displayToPublicDate":"2012-07-30T00:00:00","publicationYear":"2013","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1456,"text":"Ecological Indicators","active":true,"publicationSubtype":{"id":10}},"title":"Predicted macroinvertebrate response to water diversion from a montane stream using two-dimensional hydrodynamic models and zero flow approximation","docAbstract":"We used two-dimensional hydrodynamic models for the assessment of water diversion effects on benthic macroinvertebrates and associated habitat in a montane stream in Yosemite National Park, Sierra Nevada Mountains, CA, USA. We sampled the macroinvertebrate assemblage via Surber sampling, recorded detailed measurements of bed topography and flow, and coupled a two-dimensional hydrodynamic model with macroinvertebrate indicators to assess habitat across a range of low flows in 2010 and representative past years. We also made zero flow approximations to assess response of fauna to extreme conditions. The fauna of this montane reach had a higher percentage of Ephemeroptera, Plecoptera, and Trichoptera (%EPT) than might be expected given the relatively low faunal diversity of the study reach. The modeled responses of wetted area and area-weighted macroinvertebrate metrics to decreasing discharge indicated precipitous declines in metrics as flows approached zero. Changes in area-weighted metrics closely approximated patterns observed for wetted area, i.e., area-weighted invertebrate metrics contributed relatively little additional information above that yielded by wetted area alone. Loss of habitat area in this montane stream appears to be a greater threat than reductions in velocity and depth or changes in substrate, and the modeled patterns observed across years support this conclusion. Our models suggest that step function losses of wetted area may begin when discharge in the Merced falls to 0.02 m3/s; proportionally reducing diversions when this threshold is reached will likely reduce impacts in low flow years.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Indicators","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.ecolind.2012.03.005","usgsCitation":"Holmquist, J.G., and Waddle, T.J., 2013, Predicted macroinvertebrate response to water diversion from a montane stream using two-dimensional hydrodynamic models and zero flow approximation: Ecological Indicators, v. 28, p. 115-124, https://doi.org/10.1016/j.ecolind.2012.03.005.","productDescription":"10 p.","startPage":"115","endPage":"124","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":474072,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://escholarship.org/uc/item/97d660jq","text":"External Repository"},{"id":259272,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":259258,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.ecolind.2012.03.005","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"California","otherGeospatial":"Yosemite National Park;Sierra Nevada Mountains","volume":"28","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a8195e4b0c8380cd7b5e1","contributors":{"authors":[{"text":"Holmquist, Jeffrey G.","contributorId":77786,"corporation":false,"usgs":true,"family":"Holmquist","given":"Jeffrey","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":350285,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Waddle, Terry J.","contributorId":43430,"corporation":false,"usgs":true,"family":"Waddle","given":"Terry","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":350284,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ]}
