The objectives of this study were two-fold: (1) to determine if Coho Salmon Oncorhynchus kisutch were rearing in estuarine habitats, and (2) to characterize and compare the body length, age, condition, and duration and timing of estuarine occupancy of juvenile Coho Salmon between the two contrasting estuaries. We examined use of estuary habitats with analysis of microchemistry and microstructure of sagittal otoliths in two watersheds of south-central Alaska. Juvenile Coho Salmon were classified as estuary residents or nonresidents (recent estuary immigrants) based on otolith Sr : Ca ratios and counts of daily growth increments on otoliths. The estuaries differed in water source (glacial versus snowmelt hydrographs) and in relative estuarine and watershed area. Juvenile Coho Salmon with evidence of estuary rearing were greater in body length and condition than individuals lacking evidence of estuarine rearing. Coho Salmon captured in the glacial estuary had greater variability in body length and condition, and younger age-classes predominated the catch compared with the nearby snowmelt-fed, smaller estuary. Estuary-rearing fish in the glacial estuary arrived later and remained longer (39 versus 24 d of summer growth) during the summer than did fish using the snowmelt estuary. Finally, we observed definitive patterns of overwintering in estuarine and near shore environments in both estuaries. Evidence of estuary rearing and overwintering with differences in fish traits among contrasting estuary types refute the notion that estuaries function as only staging or transitional habitats in the early life history of Coho Salmon.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Transactions of the American Fisheries Society","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Taylor & Francis Online","doi":"10.1080/00028487.2013.815660","usgsCitation":"Hoem Neher, T.D., Rosenberger, A.E., Zimmerman, C.E., Walker, C.M., and Baird, S.J., 2013, Estuarine environments as rearing habitats for juvenile Coho Salmon in contrasting south-central Alaska watersheds: Transactions of the American Fisheries Society, v. 142, no. 6, p. 1481-1494, https://doi.org/10.1080/00028487.2013.815660.","productDescription":"16 p.","startPage":"1481","endPage":"1494","ipdsId":"IP-045003","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":286897,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1080/00028487.2013.815660"},{"id":286902,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Kenai Peninsula","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -152.09,59.16 ], [ -152.09,60.92 ], [ -148.25,60.92 ], [ -148.25,59.16 ], [ -152.09,59.16 ] ] ] } } ] }","volume":"142","issue":"6","noUsgsAuthors":false,"publicationDate":"2013-09-20","publicationStatus":"PW","scienceBaseUri":"5368b2efe4b059f7e8288336","contributors":{"authors":[{"text":"Hoem Neher, Tammy D.","contributorId":48104,"corporation":false,"usgs":true,"family":"Hoem Neher","given":"Tammy","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":477886,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rosenberger, Amanda E. 0000-0002-5520-8349 arosenberger@usgs.gov","orcid":"https://orcid.org/0000-0002-5520-8349","contributorId":5581,"corporation":false,"usgs":true,"family":"Rosenberger","given":"Amanda","email":"arosenberger@usgs.gov","middleInitial":"E.","affiliations":[{"id":396,"text":"Missouri Water Science Center","active":true,"usgs":true},{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"preferred":true,"id":477884,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Zimmerman, Christian E. 0000-0002-3646-0688 czimmerman@usgs.gov","orcid":"https://orcid.org/0000-0002-3646-0688","contributorId":410,"corporation":false,"usgs":true,"family":"Zimmerman","given":"Christian","email":"czimmerman@usgs.gov","middleInitial":"E.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true},{"id":120,"text":"Alaska Science Center Water","active":true,"usgs":true}],"preferred":true,"id":477883,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Walker, Coowe M.","contributorId":96182,"corporation":false,"usgs":false,"family":"Walker","given":"Coowe","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":477887,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Baird, Steven J.","contributorId":12375,"corporation":false,"usgs":false,"family":"Baird","given":"Steven","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":477885,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

A major challenge for local government officials and decision makers is to translate the potential global effects of climate change into actionable and cost-effective adaptation and mitigation strategies at county and municipal scales. A MODFLOW process is used to represent sub-grid scale hydrology in urban settings to help address these issues. Coupled interception, surface water, depression, and unsaturated zone storage are represented. A two-dimensional diffusive wave approximation is used to represent overland flow. Three different options for representing infiltration and recharge are presented. Additional features include structure, barrier, and culvert flow between adjacent cells, specified stage boundaries, critical flow boundaries, source/sink surface-water terms, and the bi-directional runoff to MODFLOW Surface-Water Routing process. Some abilities of the <u>U</u>rban <u>R</u>un<u>O</u>ff (URO) process are demonstrated with a synthetic problem using four land uses and varying cell coverages. Precipitation from a hypothetical storm was applied and cell by cell surface-water depth, groundwater level, infiltration rate, and groundwater recharge rate are shown. Results indicate the URO process has the ability to produce time-varying, water-content dependent infiltration and leakage, and successfully interacts with MODFLOW.","largerWorkTitle":"MODFLOW and More 2013: Translating Science into Practice: Conference Proceedings","conferenceTitle":"MODFLOW and More 2013: Translating Science into Practice","conferenceDate":"2013-06-02T00:00:00","conferenceLocation":"Golden, CO","language":"English","publisher":"Integrated GroundWater Modeling Center, Colorado School of Mines","publisherLocation":"Golden, CO","usgsCitation":"Decker, J.D., and Hughes, J., 2013, Urban runoff (URO) process for MODFLOW 2005: simulation of sub-grid scale urban hydrologic processes in Broward County, FL, p. 216-221.","productDescription":"p. 216-221","numberOfPages":"6","ipdsId":"IP-044959","costCenters":[],"links":[{"id":289445,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Florida","county":"Broward County","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -80.881233,25.95675 ], [ -80.881233,26.334698 ], [ -80.074729,26.334698 ], [ -80.074729,25.95675 ], [ -80.881233,25.95675 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53bbc187e4b084059e8bff08","contributors":{"authors":[{"text":"Decker, Jeremy D. 0000-0002-0700-515X jdecker@usgs.gov","orcid":"https://orcid.org/0000-0002-0700-515X","contributorId":514,"corporation":false,"usgs":true,"family":"Decker","given":"Jeremy","email":"jdecker@usgs.gov","middleInitial":"D.","affiliations":[{"id":269,"text":"FLWSC-Ft.

Each rhyolite is a member of the bimodal basalt-rhyolite assemblage associated with extensional tectonics that produced the Basin and Range province and Rio Grande rift, an evolving pattern of closed drainage basins, and geothermal energy or mineral resources.\n\nResults from the 0.8 Ma Bishop tuff (geothermal) in California, 1.3 to 1.6 Ma Cerro Toledo and Upper Bandelier tephra (geothermal) and 27.9 Ma Taylor Creek rhyolite (Sn) in New Mexico, 21.7 Ma Spor Mountain tuff (Be, U, F) and 24.6 Ma Pine Grove tuff (Mo) in Utah, and 27.6 Ma Hideaway Park tuff (Mo) in Colorado support the following conclusions. Melt inclusions in quartz phenocrysts from rhyolite tuffs associated with hydrothermal deposits of Sn, Mo, and Be are extremely enriched in Li (1,000s of ppm); those from Spor Mountain have the highest Li abundance yet recorded (max 5,200 ppm, median 3,750 ppm). Forty-five to 98% of the Li present in pre-eruptive magma was lost to the environment from these rhyolite tuffs. The amount of Li lost from the small volumes (1–10 km3) of Li-enriched rhyolite deposited in closed basins is sufficient to produce world-class Li brine resources. After each eruption, meteoric water leaches Li from tuff, which drains into playas, where it is concentrated by evaporation. The localized occurrence of Li-enriched rhyolites may explain why brines in arid lacustrine basins seldom have economic concentrations of Li.\n\nConsidering that hydrothermal deposits of Sn, Mo, Be, U, and F may indicate potential for Li brines in nearby basins, we surmise that the world’s largest Li brine resource in the Salar de Uyuni (10 Mt) received Li from nearby rhyolite tuffs in the Bolivian tin belt.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Economic Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Society of Economic Geologists","doi":"10.2113/econgeo.108.7.1691","usgsCitation":"Hofstra, A.H., Todorov, T., Mercer, C., Adams, D., and Marsh, E., 2013, Silicate melt inclusion evidence for extreme pre-eruptive enrichment and post-eruptive depletion of lithium in silicic volcanic rocks of the western United States: implications for the origin of lithium-rich brines: Economic Geology, v. 108, no. 7, p. 1691-1701, https://doi.org/10.2113/econgeo.108.7.1691.","productDescription":"11 p.","startPage":"1691","endPage":"1701","numberOfPages":"11","ipdsId":"IP-045184","costCenters":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"links":[{"id":282037,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":282036,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2113/econgeo.108.7.1691"}],"country":"United States","state":"California;Colorado;New Mexico;Utah","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -124.53,31.31 ], [ -124.53,41.99 ], [ -102.04,41.99 ], [ -102.04,31.31 ], [ -124.53,31.31 ] ] ] } } ] }","volume":"108","issue":"7","noUsgsAuthors":false,"publicationDate":"2013-09-30","publicationStatus":"PW","scienceBaseUri":"53cd72b4e4b0b290851087e4","contributors":{"authors":[{"text":"Hofstra, Albert H. 0000-0002-2450-1593 ahofstra@usgs.gov","orcid":"https://orcid.org/0000-0002-2450-1593","contributorId":1302,"corporation":false,"usgs":true,"family":"Hofstra","given":"Albert","email":"ahofstra@usgs.gov","middleInitial":"H.","affiliations":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":489903,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Todorov, T.I.","contributorId":10995,"corporation":false,"usgs":true,"family":"Todorov","given":"T.I.","email":"","affiliations":[],"preferred":false,"id":489904,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mercer, C.N.","contributorId":55738,"corporation":false,"usgs":true,"family":"Mercer","given":"C.N.","email":"","affiliations":[],"preferred":false,"id":489907,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Adams, D.T.","contributorId":44439,"corporation":false,"usgs":true,"family":"Adams","given":"D.T.","email":"","affiliations":[],"preferred":false,"id":489906,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Marsh, E.E.","contributorId":16628,"corporation":false,"usgs":true,"family":"Marsh","given":"E.E.","email":"","affiliations":[],"preferred":false,"id":489905,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Changes in land use, sediment supply, river flow, storminess, and sea level alter the layout of tidal channels, intertidal flats, and marsh plains; these elements define wetland complexes. Diagnostically, measurements of net sediment fluxes through tidal channels are high-temporal resolution, spatially integrated quantities that indicate (1) whether a complex is stable over seasonal timescales and (2) what mechanisms are leading to that state. We estimated sediment fluxes through tidal channels draining wetland complexes on the Blackwater and Transquaking Rivers, Maryland, USA. While the Blackwater complex has experienced decades of degradation and been largely converted to open water, the Transquaking complex has persisted as an expansive, vegetated marsh. The measured net export at the Blackwater complex (1.0 kg/s or 0.56 kg/m<sup>2</sup>/yr over the landward marsh area) was caused by northwesterly winds, which exported water and sediment on the subtidal timescale; tidally forced net fluxes were weak and precluded landward transport of suspended sediment from potential seaward sources. Though wind forcing also exported sediment at the Transquaking complex, strong tidal forcing and proximity to a turbidity maximum led to an import of sediment (0.031 kg/s or 0.70 kg/m<sup>2</sup>/yr). This resulted in a spatially averaged accretion of 3.9 mm/yr, equaling the regional relative sea level rise. Our results suggest that in areas where seaward sediment supply is dominant, seaward wetlands may be more capable of withstanding sea level rise over the short term than landward wetlands. We propose a conceptual model to determine a complex's tendency toward stability or instability based on sediment source, wetland channel location, and transport mechanisms. Wetlands with a reliable portfolio of sources and transport mechanisms appear better suited to offset natural and anthropogenic loss.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research F: Earth Surface","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Geophysical Union","doi":"10.1002/jgrf.20143","usgsCitation":"Ganju, N., Nidzieko, N.J., and Kirwan, M., 2013, Inferring tidal wetland stability from channel sediment fluxes: observations and a conceptual model: Journal of Geophysical Research F: Earth Surface, v. 118, no. 4, p. 2045-2058, https://doi.org/10.1002/jgrf.20143.","productDescription":"14 p.","startPage":"2045","endPage":"2058","numberOfPages":"14","ipdsId":"IP-049087","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":473411,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://scholarworks.wm.edu/vimsarticles/1405","text":"External Repository"},{"id":286998,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":286992,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/jgrf.20143"}],"country":"United States","state":"Maryl","otherGeospatial":"Blackwater River;Transquaking River","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -76.195,38.323 ], [ -76.195,38.462 ], [ -75.910,38.462 ], [ -75.910,38.323 ], [ -76.195,38.323 ] ] ] } } ] }","volume":"118","issue":"4","noUsgsAuthors":false,"publicationDate":"2013-10-07","publicationStatus":"PW","scienceBaseUri":"536ca76ce4b060efff280db9","contributors":{"authors":[{"text":"Ganju, Neil K. 0000-0002-1096-0465","orcid":"https://orcid.org/0000-0002-1096-0465","contributorId":93543,"corporation":false,"usgs":true,"family":"Ganju","given":"Neil K.","affiliations":[],"preferred":false,"id":493498,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nidzieko, Nicholas J.","contributorId":91018,"corporation":false,"usgs":true,"family":"Nidzieko","given":"Nicholas","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":493497,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kirwan, Matthew L. 0000-0002-0658-3038","orcid":"https://orcid.org/0000-0002-0658-3038","contributorId":84060,"corporation":false,"usgs":true,"family":"Kirwan","given":"Matthew L.","affiliations":[],"preferred":false,"id":493496,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We analyzed five years of soil CO<sub>2</sub> fluxes along a wetland gradient that varied in permafrost and soil moisture conditions. We predicted that communities with permafrost would have reduced ecosystem respiration (ER) but greater temperature sensitivity than communities without permafrost. These predictions were partially supported. The colder communities underlain by shallow permafrost had lower ecosystem respiration (ER) than communities with greater active layer thickness. However, the apparent Q<sub>10</sub> of monthly averaged ER was similar in most of the vegetation communities except the rich fen, which had smaller Q<sub>10</sub> values. Across the gradient there was a negative relationship between water table position and apparent Q<sub>10</sub>, showing that ER was more temperature sensitive under drier soil conditions. We explored whether root respiration could account for differences in ER between two adjacent communities (sedge marsh and rich fen), which corresponded to the highest and lowest ER, respectively. Despite differences in root respiration rates, roots contributed equally (~40%) to ER in both communities. Also, despite similar plant biomass, ER in the rich fen was positively related to root biomass, while ER in the sedge marsh appeared to be related more to vascular green area. Our results suggest that ER across this wetland gradient was temperature-limited, until conditions became so wet that respiration became oxygen-limited and influenced less by temperature.

The master plan proposes a combination of restoration efforts including shoreline protection, marsh creation, sediment diversions, and ridge, barrier island, and hydrological restoration. Coastal restoration projects, particularly the large-scale diversions of fresh water from the Mississippi River, needed to supply sediment to an eroding coast potentially impact oyster populations and oyster habitat. An oyster habitat suitability index model is presented that evaluates the effects of a proposed sediment and freshwater diversion into Lower Breton Sound. Voluminous freshwater, needed to suspend and broadly distribute river sediment, will push optimal salinities for oysters seaward and beyond many of the existing reefs. Implementation and operation of the Lower Breton Sound diversion structure as proposed would render about 6,173 ha of hard bottom immediately east of the Mississippi River unsuitable for the sustained cultivation of oysters. If historical harvests are to be maintained in this region, a massive and unprecedented effort to relocate private leases and restore oyster bottoms would be required. Habitat suitability index model results indicate that the appropriate location for such efforts are to the east and north of the Mississippi River Gulf Outlet.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Shellfish Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"National Shellfisheries Association","doi":"10.2983/035.032.0302","usgsCitation":"Soniat, T.M., Conzelmann, C.P., Byrd, J.D., Roszell, D.P., Bridevaux, J.L., Suir, K.J., and Colley, S.B., 2013, Predicting the effects of proposed Mississippi River diversions on oyster habitat quality; application of an oyster habitat suitability index model: Journal of Shellfish Research, v. 32, no. 3, p. 629-638, https://doi.org/10.2983/035.032.0302.","productDescription":"10 p.","startPage":"629","endPage":"638","numberOfPages":"10","ipdsId":"IP-048870","costCenters":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"links":[{"id":473414,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.2983/035.032.0302","text":"Publisher Index Page"},{"id":280732,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":280731,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2983/035.032.0302"}],"country":"United States","state":"Louisiana","otherGeospatial":"Breton Sound;Mississippi River","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -90.75,29.0 ], [ -90.75,30.75 ], [ -88.25,30.75 ], [ -88.25,29.0 ], [ -90.75,29.0 ] ] ] } } ] }","volume":"32","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd6c66e4b0b290851048ad","contributors":{"authors":[{"text":"Soniat, Thomas M.","contributorId":11109,"corporation":false,"usgs":true,"family":"Soniat","given":"Thomas","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":484437,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Conzelmann, Craig P. 0000-0002-4227-8719","orcid":"https://orcid.org/0000-0002-4227-8719","contributorId":92137,"corporation":false,"usgs":true,"family":"Conzelmann","given":"Craig","email":"","middleInitial":"P.","affiliations":[{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":false,"id":484440,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Byrd, Jason D. byrdj@usgs.gov","contributorId":4893,"corporation":false,"usgs":true,"family":"Byrd","given":"Jason","email":"byrdj@usgs.gov","middleInitial":"D.","affiliations":[],"preferred":true,"id":484435,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Roszell, Dustin P.","contributorId":16311,"corporation":false,"usgs":true,"family":"Roszell","given":"Dustin","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":484438,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Bridevaux, Joshua L.","contributorId":103567,"corporation":false,"usgs":true,"family":"Bridevaux","given":"Joshua","email":"","middleInitial":"L.","affiliations":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"preferred":false,"id":484441,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Suir, Kevin J. 0000-0003-1570-9648 suirk@usgs.gov","orcid":"https://orcid.org/0000-0003-1570-9648","contributorId":4894,"corporation":false,"usgs":true,"family":"Suir","given":"Kevin","email":"suirk@usgs.gov","middleInitial":"J.","affiliations":[{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true},{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"preferred":true,"id":484436,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Colley, Susan B.","contributorId":36844,"corporation":false,"usgs":true,"family":"Colley","given":"Susan","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":484439,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Recreation use was highest from March to April and during weekends throughout the year. Daily use of recreation trails was highest during midday. By comparing habitat use (slope, ruggedness, distance to water, and distance to recreation trails) of female bighorn sheep on weekdays versus weekends, we were able to detect short-term shifts in behavior in response to recreation. In a logistic regression of bighorn sheep locations versus random locations for March and April, female locations at midday (1200 hours) were significantly more distant from recreation trails on weekends compared with weekdays. Our results indicate that within this region of JOTR, moderate to high levels of human recreation activity may temporarily exclude bighorn females from their preferred habitat. However, the relative proximity of females to recreation trails during the weekdays before and after such habitat shifts indicates that these anthropogenic impacts were short-lived. Our results have implications for management of wildlife on public lands where the co-existence of wildlife and recreational use is a major goal.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wildlife Society Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"The Wildlife Society","doi":"10.1002/wsb.349","usgsCitation":"Longshore, K.M., Lowrey, C., and Thompson, D., 2013, Detecting short-term responses to weekend recreation activity: desert bighorn sheep avoidance of hiking trails: Wildlife Society Bulletin, v. 37, no. 4, p. 698-706, https://doi.org/10.1002/wsb.349.","productDescription":"9 p.","startPage":"698","endPage":"706","numberOfPages":"9","ipdsId":"IP-009849","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":499982,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doaj.org/article/e94d64d653cb4dd3ae768a26bbdfd675","text":"External Repository"},{"id":293719,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":293701,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/wsb.349"}],"country":"United States","state":"California","otherGeospatial":"Joshua Tree National Park","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -116.457722,33.670186 ], [ -116.457722,34.129343 ], [ -115.262191,34.129343 ], [ -115.262191,33.670186 ], [ -116.457722,33.670186 ] ] ] } } ] }","volume":"37","issue":"4","noUsgsAuthors":false,"publicationDate":"2013-10-11","publicationStatus":"PW","scienceBaseUri":"5412b9a3e4b0239f1986ba3f","chorus":{"doi":"10.1002/wsb.349","url":"http://dx.doi.org/10.1002/wsb.349","publisher":"Wiley-Blackwell","authors":"Longshore Kathleen, Lowrey Chris, Thompson Daniel B.","journalName":"Wildlife Society Bulletin","publicationDate":"10/11/2013","publiclyAccessibleDate":"10/11/2013"},"contributors":{"authors":[{"text":"Longshore, Kathleen M. 0000-0001-6621-1271 longshore@usgs.gov","orcid":"https://orcid.org/0000-0001-6621-1271","contributorId":2677,"corporation":false,"usgs":true,"family":"Longshore","given":"Kathleen","email":"longshore@usgs.gov","middleInitial":"M.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":false,"id":500707,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lowrey, Chris","contributorId":84282,"corporation":false,"usgs":true,"family":"Lowrey","given":"Chris","affiliations":[],"preferred":false,"id":500708,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Thompson, Daniel B.","contributorId":97829,"corporation":false,"usgs":true,"family":"Thompson","given":"Daniel B.","affiliations":[],"preferred":false,"id":500709,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Populations and the distribution of lesser prairie-chickens in Texas, USA, are thought to be at or near all-time lows. Currently, there is a paucity of data on the wintering ecology of the species. We measured home range, habitat use, and survival of lesser prairie-chickens during the non-breeding seasons (1 Sep-28 Feb) of 2008-2009, 2009-2010, and 2010-2011 in sand shinnery oak (Quercus havardii) landscapes in the West Texas panhandle region. Home range size did not differ among years or between females (503 ha) andmales (489 ha). Over 97% of locations of both male and female prairie-chickens were within 3.2 km of the lek of capture, and 99.9% were within 3.2 km of an available water source (i.e., livestock water tank). Habitat cover types were not used proportional to occurrence within the home ranges; grassland-dominated areas with co-occurring sand shinnery oak were used more than available, but sand sagebrush (Artemisia filifolia)-dominated areas with grassland and sand sagebrush-dominated areas with bare ground were both used less than available. Survival rates during the first 2 non-breeding seasons (&gt;80%) were among the highest reported for the species. However, survival during the third non-breeding season was only 57%, resulting in a 3-year average of 72%. It does not appear that non-breeding season mortality is a strong limiting factor in lesser prairie-chicken persistence in the study area.</p>","language":"English","publisher":"Wildlife Society","publisherLocation":"Washington, D.C.","doi":"10.1002/wsb.354","usgsCitation":"Pirius, N.E., Boal, C.W., Haukos, D.A., and Wallace, M., 2013, Winter habitat use and survival of lesser prairie-chickens in West Texas: Wildlife Society Bulletin, v. 37, no. 4, p. 759-765, https://doi.org/10.1002/wsb.354.","productDescription":"7 p.","startPage":"759","endPage":"765","numberOfPages":"7","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-037557","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"links":[{"id":499988,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doaj.org/article/8bd2278a2b34485da513e457ff581500","text":"External Repository"},{"id":300285,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"37","issue":"4","publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationDate":"2013-11-14","publicationStatus":"PW","scienceBaseUri":"5551d2c1e4b0a92fa7e93c24","contributors":{"authors":[{"text":"Pirius, Nicholas E.","contributorId":57702,"corporation":false,"usgs":true,"family":"Pirius","given":"Nicholas","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":546670,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Boal, Clint W. 0000-0001-6008-8911 cboal@usgs.gov","orcid":"https://orcid.org/0000-0001-6008-8911","contributorId":1909,"corporation":false,"usgs":true,"family":"Boal","given":"Clint","email":"cboal@usgs.gov","middleInitial":"W.","affiliations":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true},{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"preferred":true,"id":546431,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Haukos, David A. 0000-0001-5372-9960 dhaukos@usgs.gov","orcid":"https://orcid.org/0000-0001-5372-9960","contributorId":3664,"corporation":false,"usgs":true,"family":"Haukos","given":"David","email":"dhaukos@usgs.gov","middleInitial":"A.","affiliations":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true},{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"preferred":true,"id":546671,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Wallace, M.C.","contributorId":59162,"corporation":false,"usgs":true,"family":"Wallace","given":"M.C.","email":"","affiliations":[],"preferred":false,"id":546672,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Polyoxyethylene tallow amine (POEA) is a non-ionic surfactant used in many glyphosate formulations, a widely applied herbicide both in agricultural and urban environments. POEA has not been previously well characterized, but has been shown to be toxic to various aquatic organisms. Characterization of technical mixtures using ultra-high performance liquid chromatography (UHPLC) and mass spectrometry shows POEA is a complex combination of homologs of different aliphatic moieties and ranges of ethoxylate units. Tandem mass spectrometry experiments indicate that POEA homologs generate no product ions readily suitable for quantitative analysis due to poor sensitivity. A comparison of multiple high performance liquid chromatography (HPLC) and UHPLC analytical columns indicates that the stationary phase is more important in column selection than other parameters for the separation of POEA. Analysis of several agricultural and household glyphosate formulations confirms that POEA is a common ingredient but ethoxylate distributions among formulations vary.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Chromatography A","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.chroma.2013.10.032","usgsCitation":"Tush, D., Loftin, K.A., and Meyer, M.T., 2013, Characterization of polyoxyethylene tallow amine surfactants in technical mixtures and glyphosate formulations using ultra-high performance liquid chromatography and triple quadrupole mass spectrometry: Journal of Chromatography A, v. 1319, p. 80-87, https://doi.org/10.1016/j.chroma.2013.10.032.","productDescription":"8 p.","startPage":"80","endPage":"87","numberOfPages":"8","ipdsId":"IP-051127","costCenters":[{"id":353,"text":"Kansas Water Science Center","active":false,"usgs":true}],"links":[{"id":280995,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":280994,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.chroma.2013.10.032"}],"volume":"1319","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd50bbe4b0b290850f3824","contributors":{"authors":[{"text":"Tush, Daniel","contributorId":69887,"corporation":false,"usgs":true,"family":"Tush","given":"Daniel","affiliations":[],"preferred":false,"id":483279,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Loftin, Keith A. 0000-0001-5291-876X kloftin@usgs.gov","orcid":"https://orcid.org/0000-0001-5291-876X","contributorId":868,"corporation":false,"usgs":true,"family":"Loftin","given":"Keith","email":"kloftin@usgs.gov","middleInitial":"A.","affiliations":[{"id":353,"text":"Kansas Water Science Center","active":false,"usgs":true}],"preferred":true,"id":483278,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Meyer, Michael T. 0000-0001-6006-7985 mmeyer@usgs.gov","orcid":"https://orcid.org/0000-0001-6006-7985","contributorId":866,"corporation":false,"usgs":true,"family":"Meyer","given":"Michael","email":"mmeyer@usgs.gov","middleInitial":"T.","affiliations":[{"id":353,"text":"Kansas Water Science Center","active":false,"usgs":true}],"preferred":true,"id":483277,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The samples encompass the presumed hydrothermal upwelling zone in the west moat of the caldera, the Casa Diablo geothermal field, and a series of wells defining a nearly linear, ∼16 km long, west-to-east trend along the likely fluid flow path. Fluid samples were analyzed for the isotopes of water, Sr, and Ca, the concentrations of major cations and anions, alkalinity, and total CO<sub>2</sub>. Water isotope data conform to trends documented in earlier studies, interpreted as indicating a single hydrothermal fluid mixing with local groundwater. Sr isotopes show subtle changes along the flow path, which requires rapid fluid flow and minimal reaction between the channelized fluids and the wallrocks. Sr and O isotopes are used to calculate fracture spacing using a dual porosity model. Calculated fracture spacing and temperature data for hydrothermal fluids indicate the system is (approximately) at steady-state. Correlated variations among total CO<sub>2</sub>, and the concentration and isotopic composition of Ca suggest progressive fluid degassing (loss of CO<sub>2</sub>), which drives calcite precipitation as the fluid flows west-to-east and cools. The shifts in Ca isotopes require that calcite precipitated at temperatures of 150–180 °C is fractionated by ca. −0.3‰ to −0.5‰ relative to aqueous species. Our data are the first evidence that Ca isotopes undergo kinetic fractionation at high temperatures (>100 °C) and can be used to trace calcite precipitation along hydrothermal fluid flow paths.","language":"English","publisher":"Elsevier","doi":"10.1016/j.gca.2013.08.011","usgsCitation":"Brown, S.T., Kennedy, B.M., DePaolo, D., Hurwitz, S., and Evans, W.C., 2013, Ca, Sr, O and D isotope approach to defining the chemical evolution of hydrothermal fluids: example from Long Valley, CA, USA: Geochimica et Cosmochimica Acta, v. 122, p. 209-225, https://doi.org/10.1016/j.gca.2013.08.011.","productDescription":"17 p.","startPage":"209","endPage":"225","numberOfPages":"17","ipdsId":"IP-051352","costCenters":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true},{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"links":[{"id":280992,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Long Valley","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -119.34,37.4 ], [ -119.34,37.87 ], [ -118.63,37.87 ], [ -118.63,37.4 ], [ -119.34,37.4 ] ] ] } } ] }","volume":"122","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd4ffde4b0b290850f30f3","contributors":{"authors":[{"text":"Brown, Shaun T.","contributorId":68647,"corporation":false,"usgs":true,"family":"Brown","given":"Shaun","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":483815,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kennedy, B.

The geochemical parameters showed little variations over the 1.5 year study period. The highest metal concentrations found in creek sediments always coincided with the lowest metal concentrations in creek water at the slightly acidic site R3. Sequential extractions of R3 sediment revealed large portions of heavy metals (Ni, Cu, Zn, Pb, U) bound to the iron oxide fraction. Light microscopy of glass slides exposed in creeks detected twisted stalks characteristic of microaerobic FeOB of the family Gallionellaceae at R3 but also at the acidic site R2. Sequences related to FeOB such as Gallionella ferruginea, Sideroxydans sp. CL21, Ferritrophicum radicicola, and Acidovorax sp. BrG1 were identified in the sediments. The highest fraction of clone sequences similar to the acidophilic “Ferrovum myxofaciens” was detected in R1. Quantitative PCR using primer sets specific for Gallionella spp., Sideroxydans spp., and “Ferrovum myxofaciens” revealed that ~72% (R2 sediment) and 37% (R3 sediment) of total bacterial 16S rRNA gene copies could be assigned to groups of FeOB with dominance of microaerobic Gallionella spp. at both sites. Gallionella spp. had similar and very high absolute and relative gene copy numbers in both sediment communities. Thus, Gallionella-like organisms appear to exhibit a greater acid and metal tolerance than shown before. Microaerobic FeOB from R3 creek sediment enriched in newly developed metal gradient tubes tolerated metal concentrations of 35 mM Co, 24 mM Ni, and 1.3 mM Cd, higher than those in sediments. Our results will extend the limited knowledge of FeOB at contaminated, moderately to slightly acidic environments.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Frontiers in Microbiology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Frontiers Research Foundation","doi":"10.3389/fmicb.2013.00390","usgsCitation":"Fabisch, M., Beulig, F., Akob, D.M., and Küsel, K., 2013, Surprising abundance of Gallionella-related iron oxidizers in creek sediments at pH 4.4 or at high heavy metal concentrations: Frontiers in Microbiology, v. 4, 12 p., https://doi.org/10.3389/fmicb.2013.00390.","productDescription":"12 p.","numberOfPages":"12","ipdsId":"IP-052860","costCenters":[{"id":434,"text":"National Research Program","active":false,"usgs":true}],"links":[{"id":473417,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3389/fmicb.2013.00390","text":"Publisher Index Page"},{"id":281365,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281116,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.3389/fmicb.2013.00390"}],"country":"Germany","city":"Ronneburg","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 9.012929,50.201997 ], [ 9.012929,50.249873 ], [ 9.077526,50.249873 ], [ 9.077526,50.201997 ], [ 9.012929,50.201997 ] ] ] } } ] }","volume":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd7604e4b0b2908510aa18","contributors":{"authors":[{"text":"Fabisch, Maria","contributorId":17137,"corporation":false,"usgs":true,"family":"Fabisch","given":"Maria","affiliations":[],"preferred":false,"id":488529,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Beulig, Felix","contributorId":56971,"corporation":false,"usgs":true,"family":"Beulig","given":"Felix","email":"","affiliations":[],"preferred":false,"id":488530,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Akob, Denise M. 0000-0003-1534-3025 dakob@usgs.gov","orcid":"https://orcid.org/0000-0003-1534-3025","contributorId":4980,"corporation":false,"usgs":true,"family":"Akob","given":"Denise","email":"dakob@usgs.gov","middleInitial":"M.","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true},{"id":5058,"text":"Office of the Chief Scientist for Water","active":true,"usgs":true}],"preferred":true,"id":488528,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Küsel, Kirsten","contributorId":96191,"corporation":false,"usgs":false,"family":"Küsel","given":"Kirsten","affiliations":[{"id":13425,"text":"Aquatic Geomicrobiology, Institute of Ecology, Friedrich Schiller University Jena, Germany","active":true,"usgs":false}],"preferred":false,"id":488531,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

We evaluated the importance of three recommendations from the Standard Operating Procedure for hydroacoustics in the Laurentian Great Lakes (GLSOP) on density estimates of target species: noise subtraction; setting volume backscattering strength (S<sub>v</sub>) thresholds from user-defined minimum target strength (TS) of interest (TS-based S<sub>v</sub> threshold); and calculations of an index for multiple targets (N<sub>v</sub> index) to identify and remove biased TS values. Eliminating noise had the predictable effect of decreasing density estimates in most lakes. Using the TS-based Sv threshold decreased fish densities in the middle and lower layers in the deepest lakes with abundant invertebrates (e.g., Mysis diluviana). Correcting for biased in situ TS increased measured density up to 86% in the shallower lakes, which had the highest fish densities. The current recommendations by the GLSOP significantly influence acoustic density estimates, but the degree of importance is lake dependent. Applying GLSOP recommendations, whether in the Laurentian Great Lakes or elsewhere, will improve our ability to compare results among lakes. We recommend further development of standards, including minimum TS and analytical cell size, for reducing the effect of biased in situ TS on density estimates.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Great Lakes Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.jglr.2013.09.002","usgsCitation":"Kocovsky, P., Rudstam, L.G., Yule, D., Warner, D.M., Schaner, T., Pientka, B., Deller, J.W., Waterfield, H.A., Witzel, L.D., and Sullivan, P., 2013, Sensitivity of fish density estimates to standard analytical procedures applied to Great Lakes hydroacoustic data: Journal of Great Lakes Research, v. 39, no. 4, p. 655-662, https://doi.org/10.1016/j.jglr.2013.09.002.","productDescription":"8 p.","startPage":"655","endPage":"662","numberOfPages":"8","ipdsId":"IP-051226","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":280707,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":280706,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jglr.2013.09.002"}],"country":"United States","otherGeospatial":"Great Lakes","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -92.11,41.38 ], [ -92.11,48.85 ], [ -76.3,48.85 ], [ -76.3,41.38 ], [ -92.11,41.38 ] ] ] } } ] }","volume":"39","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd726de4b0b290851084d9","contributors":{"authors":[{"text":"Kocovsky, Patrick M.","contributorId":89381,"corporation":false,"usgs":true,"family":"Kocovsky","given":"Patrick M.","affiliations":[],"preferred":false,"id":484309,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rudstam, Lars G.","contributorId":56609,"corporation":false,"usgs":false,"family":"Rudstam","given":"Lars","email":"","middleInitial":"G.","affiliations":[{"id":12722,"text":"Cornell University","active":true,"usgs":false}],"preferred":false,"id":484305,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Yule, Daniel L.","contributorId":92130,"corporation":false,"usgs":true,"family":"Yule","given":"Daniel L.","affiliations":[],"preferred":false,"id":484310,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Warner, David M. 0000-0003-4939-5368 dmwarner@usgs.gov","orcid":"https://orcid.org/0000-0003-4939-5368","contributorId":2986,"corporation":false,"usgs":true,"family":"Warner","given":"David","email":"dmwarner@usgs.gov","middleInitial":"M.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":484302,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Schaner, Ted","contributorId":69939,"corporation":false,"usgs":true,"family":"Schaner","given":"Ted","email":"","affiliations":[],"preferred":false,"id":484308,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Pientka, Bernie","contributorId":57760,"corporation":false,"usgs":true,"family":"Pientka","given":"Bernie","affiliations":[],"preferred":false,"id":484306,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Deller, John W.","contributorId":48862,"corporation":false,"usgs":true,"family":"Deller","given":"John","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":484303,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Waterfield, Holly A.","contributorId":49698,"corporation":false,"usgs":true,"family":"Waterfield","given":"Holly","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":484304,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Witzel, Larry D.","contributorId":68642,"corporation":false,"usgs":true,"family":"Witzel","given":"Larry","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":484307,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Sullivan, Patrick J.","contributorId":97813,"corporation":false,"usgs":true,"family":"Sullivan","given":"Patrick J.","affiliations":[],"preferred":false,"id":484311,"contributorType":{"id":1,"text":"Authors"},"rank":10}]}}

We analyzed growth in annual egg-mass counts of the Columbia spotted frog (Rana luteiventris) across the northwestern United States, an area encompassing 3 genetic clades. On the basis of data collected by multiple partners from 98 water bodies between 1991 and 2011, we used state-space and linear-regression models to measure effects of patch characteristics, frequency of summer drought, and wetland restoration on population growth. Abundance increased in the 2 clades with greatest decline history, but declined where populations are considered most secure. Population growth was negatively associated with temporary hydroperiods and landscape modification (measured by the human footprint index), but was similar in modified and natural water bodies. The effect of drought was mediated by the size of the water body: populations in large water bodies maintained positive growth despite drought, whereas drought magnified declines in small water bodies. Rapid growth in restored wetlands in areas of historical population declines provided strong evidence of successful management. Our results highlight the importance of maintaining large areas of habitat and underscore the greater vulnerability of small areas of habitat to environmental stochasticity. Similar long-term growth rates in modified and natural water bodies and rapid, positive responses to restoration suggest pond construction and other forms of management can effectively increase population growth. These tools are likely to become increasingly important to mitigate effects of increased drought expected from global climate change.</span></p>","language":"English","publisher":"Society for Conservation Biology","doi":"10.1111/cobi.12119","usgsCitation":"Hossack, B.R., Adams, M.J., Pearl, C.A., Wilson, K.W., Bull, E.L., Lohr, K., Patla, D., Pilliod, D., Jones, J., Wheeler, K., McKay, S., and Corn, P.S., 2013, Roles of patch characteristics, drought frequency, and restoration in long-term trends of a widespread amphibian: Conservation Biology, v. 27, no. 6, p. 1410-1420, https://doi.org/10.1111/cobi.12119.","productDescription":"11 p.","startPage":"1410","endPage":"1420","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-042996","costCenters":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"links":[{"id":381612,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"27","issue":"6","noUsgsAuthors":false,"publicationDate":"2013-08-23","publicationStatus":"PW","scienceBaseUri":"5465d639e4b04d4b7dbd6674","contributors":{"authors":[{"text":"Hossack, Blake R. 0000-0001-7456-9564 blake_hossack@usgs.gov","orcid":"https://orcid.org/0000-0001-7456-9564","contributorId":1177,"corporation":false,"usgs":true,"family":"Hossack","given":"Blake","email":"blake_hossack@usgs.gov","middleInitial":"R.","affiliations":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true},{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":522863,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Adams, M.

The river has long been overallocated. Climate models project runoff losses of 5&ndash;20% from the basin by mid-21st century due to human-induced climate change. Recent work has shown that decreased snow albedo from anthropogenic dust loading to the CO mountains shortens the duration of snow cover by several weeks relative to conditions prior to western expansion of the US in the mid-1800s, and advances peak runoff at Lees Ferry, Arizona, by an average of 3 weeks. Increases in evapotranspiration from earlier exposure of soils and germination of plants have been estimated to decrease annual runoff by more than 1.0 billion cubic meters, or ~5% of the annual average. This prior work was based on observed dust loadings during 2005&ndash;2008; however, 2009 and 2010 saw unprecedented levels of dust loading on snowpacks in the Upper Colorado River Basin (UCRB), being on the order of 5 times the 2005&ndash;2008 loading. Building on our prior work, we developed a new snow albedo decay parameterization based on observations in 2009/10 to mimic the radiative forcing of extreme dust deposition. We convolve low, moderate, and extreme dust/snow albedos with both historic climate forcing and two future climate scenarios via a delta method perturbation of historic records. Compared to moderate dust, extreme dust absorbs 2&times; to 4&times; the solar radiation, and shifts peak snowmelt an additional 3 weeks earlier to a total of 6 weeks earlier than pre-disturbance. The extreme dust scenario reduces annual flow volume an additional 1% (6% compared to pre-disturbance), a smaller difference than from low to moderate dust scenarios due to melt season shifting into a season of lower evaporative demand. The sensitivity of flow timing to dust radiative forcing of snow albedo is maintained under future climate scenarios, but the sensitivity of flow volume reductions decreases with increased climate forcing. These results have implications for water management and suggest that dust abatement efforts could be an important component of any climate adaptation strategies in the UCRB.</p>","language":"English","publisher":"European Geosciences Union","doi":"10.5194/hess-17-4401-2013","usgsCitation":"Deems, J.S., Painter, T.H., Barsugli, J.J., Belnap, J., and Udall, B., 2013,

The ever-increasing and global occurrence of massive and prolonged blooms of cylindrospermopsin-producing cyanobacteria poses a potential threat to both human and ecosystem health. Its toxicity is associated with metabolic activation and may involve mechanisms that adversely affect a wide variety of targets in an organism. Cylindrospermopsin has been shown to be cytotoxic, dermatotoxic, genotoxic, hepatotoxic in vivo, developmentally toxic, and may be carcinogenic. Human exposure may occur through drinking water, during recreational activities and by consuming foods in which the toxin may have bioaccumulated. Drinking water shortages of sufficient quality coupled with growing human pressures and climate variability and change necessitate an integrated and sustainable water management program. This review presents an overview of the importance of cylindrospermopsin, its detection, toxicity, worldwide distribution, and lastly, its chemical and biological degradation and removal by natural processes and drinking water treatment processes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Science: Processes and Impacts","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"RSC","doi":"10.1039/C3EM00353A","usgsCitation":"de la Cruz, A.A., Hiskia, A., Kaloudis, T., Chernoff, N., Hill, D., Antoniou, M.G., He, X., Loftin, K., O’Shea, K., Zhao, C., Pelaez, M., Han, C., Lynch, T.J., and Dionysiou, D.D., 2013, A review on cylindrospermopsin: the global occurrence, detection, toxicity and degradation of a potent cyanotoxin: Environmental Science: Processes and Impacts, v. 15, no. 11, p. 1979-2003, https://doi.org/10.1039/C3EM00353A.","productDescription":"25 p.","startPage":"1979","endPage":"2003","ipdsId":"IP-051190","costCenters":[{"id":353,"text":"Kansas Water Science Center","active":false,"usgs":true}],"links":[{"id":280204,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":280196,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1039/C3EM00353A"}],"country":"United States","volume":"15","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"52a63fc5e4b0a6d6958821c3","contributors":{"authors":[{"text":"de la Cruz, Armah A.","contributorId":8374,"corporation":false,"usgs":true,"family":"de la Cruz","given":"Armah","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":487066,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hiskia, Anastasia","contributorId":69054,"corporation":false,"usgs":true,"family":"Hiskia","given":"Anastasia","email":"","affiliations":[],"preferred":false,"id":487074,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kaloudis, Triantafyllos","contributorId":104804,"corporation":false,"usgs":true,"family":"Kaloudis","given":"Triantafyllos","email":"","affiliations":[],"preferred":false,"id":487078,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Chernoff, Neil","contributorId":25859,"corporation":false,"usgs":true,"family":"Chernoff","given":"Neil","email":"","affiliations":[],"preferred":false,"id":487070,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hill, Donna","contributorId":82213,"corporation":false,"usgs":true,"family":"Hill","given":"Donna","email":"","affiliations":[],"preferred":false,"id":487075,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Antoniou, Maria G.","contributorId":59341,"corporation":false,"usgs":true,"family":"Antoniou","given":"Maria","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":487072,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"He, Xuexiang","contributorId":66593,"corporation":false,"usgs":true,"family":"He","given":"Xuexiang","email":"","affiliations":[],"preferred":false,"id":487073,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Loftin, Keith","contributorId":107604,"corporation":false,"usgs":true,"family":"Loftin","given":"Keith","affiliations":[],"preferred":false,"id":487079,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"O’Shea, Kevin","contributorId":37245,"corporation":false,"usgs":true,"family":"O’Shea","given":"Kevin","email":"","affiliations":[],"preferred":false,"id":487071,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Zhao, Cen","contributorId":8375,"corporation":false,"usgs":true,"family":"Zhao","given":"Cen","email":"","affiliations":[],"preferred":false,"id":487067,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Pelaez, Miguel","contributorId":98209,"corporation":false,"usgs":true,"family":"Pelaez","given":"Miguel","email":"","affiliations":[],"preferred":false,"id":487077,"contributorType":{"id":1,"text":"Authors"},"rank":11},{"text":"Han, Changseok","contributorId":97418,"corporation":false,"usgs":true,"family":"Han","given":"Changseok","email":"","affiliations":[],"preferred":false,"id":487076,"contributorType":{"id":1,"text":"Authors"},"rank":12},{"text":"Lynch, Trevor J.","contributorId":13530,"corporation":false,"usgs":true,"family":"Lynch","given":"Trevor","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":487069,"contributorType":{"id":1,"text":"Authors"},"rank":13},{"text":"Dionysiou, Dionysios D.","contributorId":12772,"corporation":false,"usgs":true,"family":"Dionysiou","given":"Dionysios","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":487068,"contributorType":{"id":1,"text":"Authors"},"rank":14}]}}

A novel design approach has produced relatively inexpensive, small-diameter probes that can be run in open or PVC-cased boreholes as small as 2 inches in diameter. The complete system, including surface electronics and various downhole probes, has been successfully tested in small-diameter monitoring wells in a range of hydrogeological settings. A variant of the probe that can be deployed by a direct-push machine has also been developed and tested in the field. The new NMR logging tool provides reliable, direct, and high-resolution information that is of importance for groundwater studies. Specifically, the technology provides direct measurement of total water content (total porosity in the saturated zone or moisture content in the unsaturated zone), and estimates of relative pore-size distribution (bound vs. mobile water content) and hydraulic conductivity. The NMR measurements show good agreement with ancillary data from lithologic logs, geophysical logs, and hydrogeologic measurements, and provide valuable information for groundwater investigations.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/gwat.12024","usgsCitation":"Walsh, D., Turner, P., Grunewald, E., Zhang, H., Butler, J.J., Reboulet, E., Knobbe, S., Christy, T., Lane, J.W., Johnson, C.D., Munday, T., and Fitzpatrick, A., 2013, A small-diameter NMR logging tool for groundwater investigations: Groundwater, v. 51, no. 6, p. 914-926, https://doi.org/10.1111/gwat.12024.","productDescription":"13 p.","startPage":"914","endPage":"926","ipdsId":"IP-042692","costCenters":[{"id":486,"text":"OGW Branch of Geophysics","active":true,"usgs":true}],"links":[{"id":349081,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"51","issue":"6","publishingServiceCenter":{"id":11,"text":"Pembroke PSC"},"noUsgsAuthors":false,"publicationDate":"2013-02-20","publicationStatus":"PW","scienceBaseUri":"5a61029ce4b06e28e9c25470","contributors":{"authors":[{"text":"Walsh, David","contributorId":27770,"corporation":false,"usgs":true,"family":"Walsh","given":"David","affiliations":[],"preferred":false,"id":722694,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Turner, Peter","contributorId":199861,"corporation":false,"usgs":false,"family":"Turner","given":"Peter","affiliations":[],"preferred":false,"id":722695,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Grunewald, Elliot","contributorId":193963,"corporation":false,"usgs":false,"family":"Grunewald","given":"Elliot","email":"","affiliations":[],"preferred":false,"id":722696,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Zhang, Hong","contributorId":199859,"corporation":false,"usgs":false,"family":"Zhang","given":"Hong","email":"","affiliations":[],"preferred":false,"id":722697,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Butler, James J.

Lake water &delta;18O ranged from +0.80 to +3.48 &permil;, reflecting the 4 m range in stage. The transient &delta;18O analysis discerned large differences in semiannual groundwater inflow, and the overall patterns of low and high groundwater inflow were consistent with an independent water budget. Despite simplifying assumptions that the isotopic composition of precipitation (&delta;P), groundwater inflow, and atmospheric moisture (&delta;A) were constant, groundwater inflow was within the water-budget error for 12 of the 19 semiannual calculation periods. The magnitude of inflow was over or under predicted during periods of climatic extreme. During periods of high net precipitation from tropical cyclones and El Ni&ntilde;o conditions, &delta;P values were considerably more depleted in 18O than assumed. During an extreme dry period, &delta;A values were likely more enriched in 18O than assumed due to the influence of local lake evaporate. Isotope balance results were most sensitive to uncertainties in relative humidity, evaporation, and &delta;18O of lake water, which can limit precise quantification of groundwater inflow. Nonetheless, the consistency between isotope-balance and water-budget results indicates that this is a viable approach for lakes in similar settings, allowing the magnitude of groundwater inflow to be estimated over less-than-annual time periods.

In April 2010, management responses to the Deepwater Horizon oil spill resulted in extreme low salinity (&lt;5) at all sites through August 2010; in 2011, a 100-year Mississippi River flood event resulted in low salinity in late spring.

In 2011, recruitment was limited, which may be due to a combination of low spring time salinities, high 2010 oyster mortality, minimal 2010 recruitment, cumulative effects from 10 years of declining oyster stock in the area, and poor cultch quality.

We sought to define impacts in fields (including field borders) of the southeastern region’s commercial production of corn, wheat, soy, and cotton. The metric is intended to serve as an educational tool, allowing producers to see how operational decisions made at the field level impact overall vertebrate species richness and to explore decision impacts to targeted species groups (e.g. game, pest, or beneficial species). </p><p>Agricultural landscapes are often mistakenly thought to be unsuitable habitat for most species. However, as demonstrated by results reported here, even large-scale, conventional agricultural producers are potentially important partners in biodiversity conservation. Many vertebrate species do inhabit agricultural landscapes, benefitting from the provision of water, food, or shelter within cultivated fields and their immediate borders (e.g., Holland et al. 2012). In the Southeastern US, of the 613 terrestrial vertebrate species modeled by the Southeast Gap Analysis Program (SEGAP) (http://www.basic.ncsu.edu/segap/index.html), 263 utilize row crop and associated agricultural land cover classes as potential habitat (Box 1). While some species may be sensitive to certain operational practices (e.g., tillage, pest management, or field border management practices), others are generally tolerant, and some may benefit either directly or indirectly. For example, field margins and ditches often serve as semi-natural habitats providing foraging resources and shelter for vertebrates and are shown to positively influence species richness and abundance (Billeter et al. 2007; Herzon &amp; Helenius 2008; Marshall &amp; Moonen 2002; Shore et al. 2005; Weibull et al. 2003; Wuczyńskia et al. 2011). Biodiversity responses are, therefore, complex, as an individual species’ responses to agricultural production practices depends on that animal’s resource specialization, mobility, and life history strategies (Jeanneret et al. 2003a, b; Jennings &amp; Pocock 2009). </p><p>The knowledge necessary to define the biodiversity contribution of agricultural lands is specialized, dispersed, and nuanced, and thus not readily accessible. Given access to clearly defined biodiversity tradeoffs between alternative agricultural practices, landowners, land managers and farm operators could collectively enhance the conservation and economic value of agricultural landscapes. Therefore, Field to Market: The Keystone Alliance for Sustainable Agriculture and The Nature Conservancy jointly funded a pilot project to develop a biodiversity metric to integrate into Field to Market’s existing sustainability calculator, The Fieldprint Calculator (http://www. fieldtomarket.org/). Field to Market: The Keystone Alliance for Sustainable Agriculture is an alliance among producers, agribusinesses, food companies, and conservation organizations seeking to create sustainable outcomes for agriculture. The Fieldprint Calculator supports the Keystone Alliance’s vision to achieve safe, accessible, and nutritious food, fiber and fuel in thriving ecosystems to meet the needs of 9 billion people in 2050. In support of this same vision, our project provides proof-of-concept for an outcome-based biodiversity metric for Field to Market to quantify biodiversity impacts of commercial row crop production on terrestrial vertebrate richness. </p><p>Little research exists examining the impacts of alternative commercial agricultural practices on overall terrestrial biodiversity (McLaughlin &amp; Mineau 1995). Instead, most studies compare organic versus conventional practices (e.g. Freemark &amp; Kirk 2001; Wickramasinghe et al. 2004), and most studies focus on flora, avian, or invertebrate communities (Jeanneret et al. 2003a; Maes et al. 2008; Pollard &amp; Relton 1970).&nbsp;Therefore, we used an expert-knowledge-based approach to develop a metric that predicts expected impacts to shelter and forage resources, individual species, and overall biodiversity (species richness). This approach is modeled after an ecosystems services concept (WRI 2005), except that we examine services (i.e., resources) provided to vertebrate wildlife rather than service provided to the human population. SEGAP predicts species that are potentially present in an area given landscape-scale habitat availability, configuration, and context (e.g., patch size, proximity to resources, connectivity, potential for disturbance). Based on the prediction of species that may be potentially present, the impacts of management decisions within fields and around their borders can be analyzed based on the impact of those practices to the availability of species’ resources. The final metric provides an index of a producer’s relative impact, but perhaps even more importantly, the underlying database allows producers to explore details such as which species are most impacted or how alternative decisions would impact their score.&nbsp;</p>","language":"English","publisher":"North Carolina Agricultral Research Service, College of Agriculture and Life Sciences, North Carolina State University","usgsCitation":"Drew, C.A., Alexander-Vaughn, L.B., Collazo, J., McKerrow, A., and Anderson, J., 2013, Developing an outcome-based biodiversity metric in support of the field to market project: Final report: Technical Bulletin 334, 28 p.","productDescription":"28 p.","ipdsId":"IP-046155","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true},{"id":37226,"text":"Core Science Analytics, Synthesis, and Libraries","active":true,"usgs":true},{"id":38315,"text":"GAP Analysis Project","active":true,"usgs":true}],"links":[{"id":350596,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":350595,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://www.basic.ncsu.edu/eda/downloads/BiodiversityReport_Text.pdf"}],"publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5a6afac9e4b06e28e9c9a91e","contributors":{"authors":[{"text":"Drew, C.

Understanding how changes in primary productivity are associated with variability in moisture and temperature will become increasingly important with current and anticipated changes in climate. Our objective was to describe patterns and variability in aboveground live vascular plant biomass in relation to climatic factors. We harvested aboveground biomass at peak growth from four 64-m</span><sup>2</sup><span> plots each in xeric, mesic, and hydric meadows annually from 1994 to 2000. Data from nearby weather stations provided independent variables of spring snow water content, snow-free date, and thawing degree days for a cumulative index of available energy. We assembled these climatic variables into a set of mixed effects analysis of covariance models to evaluate their relationships with annual aboveground net primary productivity (ANPP), and we used an information theoretic approach to compare the quality of fit among candidate models. ANPP in the xeric meadow was negatively related to snow water content and thawing degree days and in the mesic meadow was negatively related to snow water content. Relationships between ANPP and these 2 covariates in the hydric meadow were not significant. Increasing snow water content may limit ANPP in these meadows if anaerobic conditions delay microbial activity and nutrient availability. Increased thawing degree days may limit ANPP in xeric meadows by prematurely depleting soil moisture. Large within-year variation of ANPP in the hydric meadow limited sensitivity to the climatic variables. These relationships suggest that, under projected warmer and drier conditions, ANPP will increase in mesic meadows but remain unchanged in xeric meadows because declines associated with increased temperatures would offset the increases from decreased snow water content.</span></p>","language":"English","publisher":"Monte L.

General environmental conditions (e.g., biofouling, turbidity) and carbon-specific conditions (e.g., wide diel variations) present significant challenges to acquiring long-term measurements of dissolved inorganic carbon (DIC) with satisfactory accuracy and resolution. SEAS-DIC is a new in situ instrument designed to provide calibrated, high-frequency, long-term measurements of DIC in marine and fresh waters. Sample water is first acidified to convert all DIC to carbon dioxide (CO</span><span>2</span><span>). The sample and a known reagent solution are then equilibrated across a gas-permeable membrane. Spectrophotometric measurement of reagent pH can thereby determine the sample DIC over a wide dynamic range, with inherent calibration provided by the pH indicator&rsquo;s molecular characteristics. Field trials indicate that SEAS-DIC performs well in biofouling and turbid waters, with a DIC accuracy and precision of &sim;2 &mu;mol kg</span><span>&ndash;1</span><span>&nbsp;and a measurement rate of approximately once per minute. The acidic reagent protects the sensor cell from biofouling, and the gas-permeable membrane excludes particulates from the optical path.

The three study catchments were: a 142.3 ha old secondary forest, a 175.6 ha mosaic of mixed age forest, pasture, and subsistence agriculture, and a 35.9 ha actively grazed pasture subcatchment of the mosaic catchment. The two larger catchments are adjacent, with similar morphology, soils, underlying geology, and rainfall. Annual water balances, peak runoff rates, runoff efficiencies, and dry season recessions show significant differences. Dry season runoff from the forested catchment receded more slowly than from the mosaic and pasture catchments. The runoff rate from the forest catchment was 1&ndash;50% greater than that from the similarly sized mosaic catchment at the end of the dry season. This observation supports the sponge-effect hypothesis. The pasture and mosaic catchment median runoff efficiencies were 2.7 and 1.8 times that of the forest catchment, respectively, and increased with total storm rainfall. Peak runoff rates from the pasture and mosaic catchments were 1.7 and 1.4 times those of the forest catchment, respectively. The forest catchment produced 35% less total runoff and smaller peak runoff rates during the flood of record in the Panama Canal Watershed. Flood peak reduction and increased streamflows through dry periods are important benefits relevant to watershed management, payment for ecosystem services, water-quality management, reservoir sedimentation, and fresh water security in the Panama Canal watershed and similar tropical landscapes.</span></p>","language":"English","publisher":"Wiley","doi":"10.1002/2013WR013956","usgsCitation":"Ogden, F.L., Crouch, T.D., Stallard, R.F., and Hall, J.S., 2013, Effect of land cover and use on dry season river runoff, runoff efficiency, and peak storm runoff in the seasonal tropics of Central Panama: Water Resources Research, v. 49, no. 12, p. 8443-8462, https://doi.org/10.1002/2013WR013956.","productDescription":"20 p.","startPage":"8443","endPage":"8462","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-045298","costCenters":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"links":[{"id":473428,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/2013wr013956","text":"Publisher Index Page"},{"id":322082,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Panama","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -80.15625,\n              8.635334050763124\n            ],\n            [\n              -80.15625,\n              9.546583349757574\n            ],\n            [\n              -79.310302734375,\n              9.546583349757574\n            ],\n            [\n              -79.310302734375,\n              8.635334050763124\n            ],\n            [\n              -80.15625,\n              8.635334050763124\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"49","issue":"12","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationDate":"2013-12-17","publicationStatus":"PW","scienceBaseUri":"575158b0e4b053f0edd03c38","contributors":{"authors":[{"text":"Ogden, Fred L.","contributorId":169952,"corporation":false,"usgs":false,"family":"Ogden","given":"Fred","email":"","middleInitial":"L.","affiliations":[{"id":590,"text":"U.S. Army Corps of Engineers","active":false,"usgs":false}],"preferred":false,"id":631596,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Crouch, Trey D.","contributorId":169953,"corporation":false,"usgs":false,"family":"Crouch","given":"Trey","email":"","middleInitial":"D.","affiliations":[{"id":590,"text":"U.S. Army Corps of Engineers","active":false,"usgs":false}],"preferred":false,"id":631597,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Stallard, Robert F. 0000-0001-8209-7608 stallard@usgs.gov","orcid":"https://orcid.org/0000-0001-8209-7608","contributorId":1924,"corporation":false,"usgs":true,"family":"Stallard","given":"Robert","email":"stallard@usgs.gov","middleInitial":"F.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"preferred":true,"id":631595,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hall, Jefferson S.","contributorId":169939,"corporation":false,"usgs":false,"family":"Hall","given":"Jefferson","email":"","middleInitial":"S.","affiliations":[{"id":25632,"text":"Smithsonian Tropical Research Institute, Balboa, Panama","active":true,"usgs":false}],"preferred":false,"id":631598,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}
