Exurban development is intermediate-intensity residential development that often occurs in natural landscapes. Most species-habitat models do not evaluate the effects of such intermediate levels of human development and even fewer predict how future development patterns might affect the amount and configuration of habitat. We addressed these deficiencies by interfacing a habitat model with a spatially-explicit housing-density model to study the effect of human land uses on the habitat of pumas (Puma concolor) in southern California. We studied the response of pumas to natural and anthropogenic features within their home ranges and how mortality risk varied across a gradient of human development. We also used our housing-density model to estimate past and future housing densities and model the distribution of puma habitat in 1970, 2000, and 2030. The natural landscape for pumas in our study area consisted of riparian areas, oak woodlands, and open, conifer forests embedded in a chaparral matrix. Pumas rarely incorporated suburban or urban development into their home ranges, which is consistent with the hypothesis that the behavioral decisions of individuals can be collectively manifested as population-limiting factors at broader spatial scales. Pumas incorporated rural and exurban development into their home ranges, apparently perceiving these areas as modified, rather than non-habitat. Overall, pumas used exurban areas less than expected and showed a neutral response to rural areas. However, individual pumas that selected for or showed a neutral response to exurban areas had a higher risk of mortality than pumas that selected against exurban habitat. Exurban areas are likely hotspots for puma-human conflict in southern California. Approximately 10% of our study area will transform from exurban, rural, or undeveloped areas to suburban or urban by 2030, and 35% of suitable puma habitat on private land in 1970 will have been lost by 2030. These land-use changes will further isolate puma populations in southern California, but the ability to visualize these changes had provided a new tool for developing proactive conservation solutions.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecosphere","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Ecological Society of America","publisherLocation":"Ithaca, NY","doi":"10.1890/ES10-00005.1","usgsCitation":"Burdett, C.L., Crooks, K.R., Theobald, D.M., Wilson, K.R., Boydston, E.E., Lyren, L.A., Fisher, R.N., Vickers, T., Morrison, S.A., and Boyce, W.M., 2010, Interfacing models of wildlife habitat and human development to predict the future distribution of puma habitat: Ecosphere, v. 1, no. 1, https://doi.org/10.1890/ES10-00005.1.","startPage":"Article 4","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":475487,"rank":201,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1890/es10-00005.1","text":"Publisher Index Page"},{"id":257093,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":257082,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://dx.doi.org/10.1890/ES10-00005.1","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"California","volume":"1","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-07-31","publicationStatus":"PW","scienceBaseUri":"505a3cfae4b0c8380cd631d0","contributors":{"authors":[{"text":"Burdett, Christopher L.","contributorId":13086,"corporation":false,"usgs":true,"family":"Burdett","given":"Christopher","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":348382,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Crooks, Kevin R.","contributorId":51137,"corporation":false,"usgs":false,"family":"Crooks","given":"Kevin","email":"","middleInitial":"R.","affiliations":[{"id":6621,"text":"Colorado State University","active":true,"usgs":false}],"preferred":false,"id":348384,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Theobald, David M. 0000-0002-1271-9368","orcid":"https://orcid.org/0000-0002-1271-9368","contributorId":10271,"corporation":false,"usgs":false,"family":"Theobald","given":"David","email":"","middleInitial":"M.","affiliations":[{"id":13470,"text":"Conservation Science Partners","active":true,"usgs":false}],"preferred":true,"id":348381,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Wilson, Kenneth R.","contributorId":29255,"corporation":false,"usgs":true,"family":"Wilson","given":"Kenneth","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":348383,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Boydston, Erin E. 0000-0002-8452-835X eboydston@usgs.gov","orcid":"https://orcid.org/0000-0002-8452-835X","contributorId":1705,"corporation":false,"usgs":true,"family":"Boydston","given":"Erin","email":"eboydston@usgs.gov","middleInitial":"E.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":348380,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Lyren, Lisa A.","contributorId":87407,"corporation":false,"usgs":true,"family":"Lyren","given":"Lisa","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":348388,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Fisher, Robert N. 0000-0002-2956-3240 rfisher@usgs.gov","orcid":"https://orcid.org/0000-0002-2956-3240","contributorId":1529,"corporation":false,"usgs":true,"family":"Fisher","given":"Robert","email":"rfisher@usgs.gov","middleInitial":"N.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":348379,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Vickers, T.

Parasitism is the most popular life-style on Earth, and many vertebrates host more than one kind of parasite at a time. A common assumption is that parasite species rarely interact, because they often exploit different tissues in a host, and this use of discrete resources limits competition (1). On page 243 of this issue, however, Telfer et al. (2) provide a convincing case of a highly interactive parasite community in voles, and show how infection with one parasite can affect susceptibility to others. If some human parasites are equally interactive, our current, disease-by-disease approach to modeling and treating infectious diseases is inadequate (3).

Telfer et al.'s study—which involved tracking infections of four different parasites by taking blood samples from nearly 6000 wild voles (Microtus agrestis) over 5 years—helps highlight our growing understanding of how parasites can interact in complex ways (see the figure). What are some of the take-home messages?

The loggerhead sea turtle Caretta caretta faces declining nest numbers and bycatches from commercial longline fishing in the southeastern USA. Understanding spatial and temporal habitat-use patterns of these turtles, especially reproductive females in the neritic zone, is critical for guiding management decisions. To assess marine turtle habitat use within the Dry Tortugas National Park (DRTO), we used satellite telemetry to identify core-use areas for 7 loggerhead females inter-nesting and tracked in 2008 and 2009. This effort represents the first tracking of DRTO loggerheads, a distinct subpopulation that is 1 of 7 recently proposed for upgrading from threatened to endangered under the US Endangered Species Act. We also used a rapid, high-resolution, digital imaging system to map benthic habitats in turtle core-use areas (i.e. 50% kernel density zones). Loggerhead females were seasonal residents of DRTO for 19 to 51 d, and individual inter-nesting habitats were located within 1.9 km (2008) and 2.3 km (2009) of the nesting beach and tagging site. The core area common to all tagged turtles was 4.2 km2 in size and spanned a depth range of 7.6 to 11.5 m. Mapping results revealed the diversity and distributions of benthic cover available in the core-use area, as well as a heavily used corridor to/from the nesting beach. This combined tagging-mapping approach shows potential for planning and improving the effectiveness of marine protected areas and for developing spatially explicit conservation plans.

To examine the potential effect of sea level rise on community vulnerability to future hurricanes, we assess variations in socioeconomic exposure in Sarasota County, FL, to contemporary hurricane storm-surge hazards and to storm-surge hazards enhanced by sea level rise scenarios. Analysis indicates that significant portions of the population, economic activity, and critical facilities are in contemporary and future hurricane storm-surge hazard zones. The addition of sea level rise to contemporary storm-surge hazard zones effectively causes population and asset (infrastructure, natural resources, etc) exposure to be equal to or greater than what is in the hazard zone of the next higher contemporary Saffir–Simpson hurricane category. There is variability among communities for this increased exposure, with greater increases in socioeconomic exposure due to the addition of sea level rise to storm-surge hazard zones as one progresses south along the shoreline. Analysis of the 2050 comprehensive land use plan suggests efforts to manage future growth in residential, economic and infrastructure development in Sarasota County may increase societal exposure to hurricane storm-surge hazards.","language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.apgeog.2010.05.005","usgsCitation":"Frazier, T.G., Wood, N., Yarnal, B., and Bauer, D.H., 2010, Influence of potential sea level rise on societal vulnerability to hurricane storm-surge hazards, Sarasota County, Florida: Applied Geography, v. 30, no. 4, p. 490-505, https://doi.org/10.1016/j.apgeog.2010.05.005.","productDescription":"16 p.","startPage":"490","endPage":"505","costCenters":[{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"links":[{"id":257015,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Florida","county":"Sarasota","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -82.72499084472656,\n 27.010196431931526\n ],\n [\n -82.25669860839844,\n 27.010196431931526\n ],\n [\n -82.25669860839844,\n 27.502790131319642\n ],\n [\n -82.72499084472656,\n 27.502790131319642\n ],\n [\n -82.72499084472656,\n 27.010196431931526\n ]\n ]\n ]\n }\n }\n ]\n}","volume":"30","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3b66e4b0c8380cd624d3","chorus":{"doi":"10.1016/j.apgeog.2010.05.005","url":"http://dx.doi.org/10.1016/j.apgeog.2010.05.005","publisher":"Elsevier BV","authors":"Frazier Tim G., Wood Nathan, Yarnal Brent, Bauer Denise H.","journalName":"Applied Geography","publicationDate":"12/2010","auditedOn":"10/29/2014"},"contributors":{"authors":[{"text":"Frazier, Tim G.","contributorId":64793,"corporation":false,"usgs":true,"family":"Frazier","given":"Tim","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":346942,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wood, Nathan 0000-0002-6060-9729 nwood@usgs.gov","orcid":"https://orcid.org/0000-0002-6060-9729","contributorId":71151,"corporation":false,"usgs":true,"family":"Wood","given":"Nathan","email":"nwood@usgs.gov","affiliations":[{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"preferred":false,"id":346943,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Yarnal, Brent","contributorId":31839,"corporation":false,"usgs":true,"family":"Yarnal","given":"Brent","email":"","affiliations":[],"preferred":false,"id":346941,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bauer, Denise H.","contributorId":94171,"corporation":false,"usgs":true,"family":"Bauer","given":"Denise","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":346944,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70007480,"text":"70007480 - 2010 - Influence of environmental factors on biotic responses to nutrient enrichment in agricultural streams","interactions":[],"lastModifiedDate":"2012-05-30T01:01:38","indexId":"70007480","displayToPublicDate":"2012-05-21T10:33:00","publicationYear":"2010","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2529,"text":"Journal of the American Water Resources Association","active":true,"publicationSubtype":{"id":10}},"title":"Influence of environmental factors on biotic responses to nutrient enrichment in agricultural streams","docAbstract":"The influence of environmental factors on biotic responses to nutrients was examined in three diverse agricultural regions of the United States. Seventy wadeable sites were selected along an agricultural land use gradient while minimizing natural variation within each region. Nutrients, habitat, algae, macroinvertebrates, and macrophyte cover were sampled during a single summer low-flow period in 2006 or 2007. Continuous stream stage and water temperature were collected at each site for 30 days prior to sampling. Wide ranges of concentrations were found for total nitrogen (TN) (0.07-9.61 mg/l) and total phosphorus (TP) (<0.004-0.361 mg/l), but biotic responses including periphytic and sestonic chlorophyll a (RCHL and SCHL, respectively), and percent of stream bed with aquatic macrophyte (AQM) growth were not strongly related to concentrations of TN or TP. Pearson's coefficient of determination (R2) for nutrients and biotic measures across all sites ranged from 0.08 to 0.32 and generally were not higher within each region. The biotic measures (RCHL, SCHL, and AQM) were combined in an index to evaluate eutrophic status across sites that could have different biotic responses to nutrient enrichment. Stepwise multiple regression identified TN, percent canopy, median riffle depth, and daily percent change in stage as significant factors for the eutrophic index (R2 = 0.50, p < 0.001). A TN threshold of 0.48 mg/l was identified where eutrophic index scores became less responsive to increasing TN concentrations, for all sites. Multiple plant growth indicators should be used when evaluating eutrophication, especially when streams contain an abundance of macrophytes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of the American Water Resources Association","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Water Resources Association","publisherLocation":"Middleburg, VA","doi":"10.1111/j.1752-1688.2010.00430.x","usgsCitation":"Maret, T.R., Konrad, C.P., and Tranmer, A.W., 2010, Influence of environmental factors on biotic responses to nutrient enrichment in agricultural streams: Journal of the American Water Resources Association, v. 46, no. 3, p. 498-513, https://doi.org/10.1111/j.1752-1688.2010.00430.x.","productDescription":"16 p.","startPage":"498","endPage":"513","costCenters":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"links":[{"id":475489,"rank":101,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1752-1688.2010.00430.x","text":"Publisher Index Page"},{"id":257017,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":257011,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://dx.doi.org/10.1111/j.1752-1688.2010.00430.x","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Arkansas;Idaho;Minnesota;Missouri;Nevada;Oklahoma;Wisconsin","volume":"46","issue":"3","noUsgsAuthors":false,"publicationDate":"2010-06-07","publicationStatus":"PW","scienceBaseUri":"505a3b2fe4b0c8380cd622d2","contributors":{"authors":[{"text":"Maret, Terry R. trmaret@usgs.gov","contributorId":953,"corporation":false,"usgs":true,"family":"Maret","given":"Terry","email":"trmaret@usgs.gov","middleInitial":"R.","affiliations":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"preferred":true,"id":356456,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Konrad, Christopher P. 0000-0002-7354-547X cpkonrad@usgs.gov","orcid":"https://orcid.org/0000-0002-7354-547X","contributorId":1716,"corporation":false,"usgs":true,"family":"Konrad","given":"Christopher","email":"cpkonrad@usgs.gov","middleInitial":"P.","affiliations":[{"id":622,"text":"Washington Water Science Center","active":true,"usgs":true}],"preferred":true,"id":356457,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Tranmer, Andrew W.","contributorId":44243,"corporation":false,"usgs":true,"family":"Tranmer","given":"Andrew","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":356458,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":70003607,"text":"70003607 - 2010 - Experimental drought in a tropical rain forest increases soil carbon dioxide losses to the atmosphere","interactions":[],"lastModifiedDate":"2021-01-13T16:50:05.296009","indexId":"70003607","displayToPublicDate":"2012-05-21T08:17:00","publicationYear":"2010","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1465,"text":"Ecology","active":true,"publicationSubtype":{"id":10}},"title":"Experimental drought in a tropical rain forest increases soil carbon dioxide losses to the atmosphere","docAbstract":"

Climate models predict precipitation changes for much of the humid tropics, yet few studies have investigated the potential consequences of drought on soil carbon (C) cycling in this important biome. In wet tropical forests, drought could stimulate soil respiration via overall reductions in soil anoxia, but previous research suggests that litter decomposition is positively correlated with high rainfall fluxes that move large quantities of dissolved organic matter (DOM) from the litter layer to the soil surface. Thus, reduced rainfall could also limit C delivery to the soil surface, reducing respiration rates. We conducted a throughfall manipulation experiment to investigate how 25% and 50% reductions in rainfall altered both C movement into soils and the effects of those DOM fluxes on soil respiration rates. In response to the experimental drought, soil respiration rates increased in both the −25% and −50% treatments. Throughfall fluxes were reduced by 26% and 55% in the −25% and −50% treatments, respectively. However, total DOM fluxes leached from the litter did not vary between treatments, because the concentrations of leached DOM reaching the soil surface increased in response to the simulated drought. Annual DOM concentrations averaged 7.7 ± 0.8, 11.2 ± 0.9, and 15.8 ± 1.2 mg C/L in the control, −25%, and −50% plots, respectively, and DOM concentrations were positively correlated with soil respiration rates. A laboratory incubation experiment confirmed the potential importance of DOM concentration on soil respiration rates, suggesting that this mechanism could contribute to the increase in CO2 fluxes observed in the reduced rainfall plots. Across all plots, the data suggested that soil CO2 fluxes were partially regulated by the magnitude and concentration of soluble C delivered to the soil, but also by soil moisture and soil oxygen availability. Together, our data suggest that declines in precipitation in tropical rain forests could drive higher CO2 fluxes to the atmosphere both via increased soil O2 availability and through responses to elevated DOM concentrations.

Monitoring of the marine environment for secondary impacts has been minimal, although microcystin-contaminated freshwater is known to be entering marine ecosystems. Here we confirm deaths of marine mammals from microcystin intoxication and provide evidence implicating land-sea flow with trophic transfer through marine invertebrates as the most likely route of exposure. This hypothesis was evaluated through environmental detection of potential freshwater and marine microcystin sources, sea otter necropsy with biochemical analysis of tissues and evaluation of bioaccumulation of freshwater microcystins by marine invertebrates. Ocean discharge of freshwater microcystins was confirmed for three nutrient-impaired rivers flowing into the Monterey Bay National Marine Sanctuary, and microcystin concentrations up to 2,900 ppm (2.9 million ppb) were detected in a freshwater lake and downstream tributaries to within 1 km of the ocean. Deaths of 21 southern sea otters, a federally listed threatened species, were linked to microcystin intoxication. Finally, farmed and free-living marine clams, mussels and oysters of species that are often consumed by sea otters and humans exhibited significant biomagnification (to 107 times ambient water levels) and slow depuration of freshwater cyanotoxins, suggesting a potentially serious environmental and public health threat that extends from the lowest trophic levels of nutrient-impaired freshwater habitat to apex marine predators. Microcystin-poisoned sea otters were commonly recovered near river mouths and harbors and contaminated marine bivalves were implicated as the most likely source of this potent hepatotoxin for wild otters. This is the first report of deaths of marine mammals due to cyanotoxins and confirms the existence of a novel class of marine \"harmful algal bloom\" in the Pacific coastal environment; that of hepatotoxic shellfish poisoning (HSP), suggesting that animals and humans are at risk from microcystin poisoning when consuming shellfish harvested at the land-sea interface.","language":"English","publisher":"Public Library of Science","doi":"10.1371/journal.pone.0012576","usgsCitation":"Miller, M.A., Kudela, R.M., Mekebri, A., Crane, D., Oates, S.C., Tinker, M.T., Staedler, M., Miller, W.A., Toy-Choutka, S., Dominik, C., Hardin, D., Langlois, G., Murray, M., Ward, K., and Jessup, D., 2010, Evidence for a novel marine harmful algal bloom: Cyanotoxin (Microcystin) transfer from land to sea otters: PLoS ONE, v. 5, no. 9, p. 1-11, https://doi.org/10.1371/journal.pone.0012576.","productDescription":"e12576; 11 p.","startPage":"1","endPage":"11","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true},{"id":34983,"text":"Contaminant Biology Program","active":true,"usgs":true}],"links":[{"id":475490,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pone.0012576","text":"Publisher Index Page"},{"id":256990,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Monterey Bay National Marine Sanctuary","volume":"5","issue":"9","noUsgsAuthors":false,"publicationDate":"2010-09-10","publicationStatus":"PW","scienceBaseUri":"505a0d30e4b0c8380cd52e76","contributors":{"authors":[{"text":"Miller, Melissa A.","contributorId":57701,"corporation":false,"usgs":false,"family":"Miller","given":"Melissa","email":"","middleInitial":"A.","affiliations":[{"id":39007,"text":"CA Dept of Fish and Wildlife","active":true,"usgs":false}],"preferred":false,"id":349350,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kudela, Raphael M.","contributorId":95313,"corporation":false,"usgs":true,"family":"Kudela","given":"Raphael","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":349355,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mekebri, Abdu","contributorId":17859,"corporation":false,"usgs":true,"family":"Mekebri","given":"Abdu","affiliations":[],"preferred":false,"id":349344,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Crane, Dave","contributorId":72629,"corporation":false,"usgs":true,"family":"Crane","given":"Dave","email":"","affiliations":[],"preferred":false,"id":349351,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Oates, Stori C.","contributorId":84196,"corporation":false,"usgs":true,"family":"Oates","given":"Stori","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":349353,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Tinker, M.

The mosquito larvicide methoprene is a juvenile growth hormone mimic that is widely used to control mosquito larvae in stormwater catch basins. This study addresses two concerns pertaining to methoprene's use for mosquito control. First, measurements of methoprene concentrations were made from water in catch basins that had been treated with methoprene and from an adjoining salt pond near where the treated catch basins emptied. The concentrations of methoprene in catch basins and at drainage outlets after application at the rates currently used for mosquito control in southern Rhode Island were 0.5 ppb and lower, orders of magnitude below what has been determined as detrimental to organisms other than mosquitoes. Second, the effects of methoprene on the communities that live in catch basins were evaluated both in simulated catch basins in the laboratory and in actual catch basins in the field. We found no evidence of declines in abundances of any taxa attributable to the application. Furthermore, we found no consistent changes in community-level parameters (e.g., taxonomic richness, and dominance-diversity relationships) related to methoprene application in either field or laboratory trials.

We test the prediction that smaller distances between neighboring seeds in drill seeded grassland plantings would result in lower species diversity, greater weed abundance, and larger conspecific patch sizes than otherwise similar broadcast seeded plantings. A diverse grassland seed mix was either drill seeded, which places seeds in equally spaced rows, or broadcast seeded, which spreads seeds across the ground surface, into 24 plots in each of three sites in 2005. In summer 2007, we measured species abundance in a 1 m2 quadrat in each plot and mapped common species within the quadrat by recording the most abundant species in each of 64 cells. Quadrat-scale diversity and weed abundance were similar between drilled and broadcast plots, suggesting that processes that limited establishment and controlled invasion were not affected by such fine-scale seed distribution. However, native warm-season (C4) grasses were more abundant and occurred in less compact patches in drilled plots. This difference in C4 grass abundance and distribution may result from increased germination or vegetative propagation of C4 grasses in drilled plots. Our findings suggest that local plant density may control fine-scale heterogeneity and species composition in restored grasslands, processes that need to be further investigated to determine whether seed distributions can be manipulated to increase diversity in restored grasslands.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Restoration Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Society for Ecological Restoration International","publisherLocation":"Washington D.C.","usgsCitation":"Yurkonis, K.A., Wilsey, B.J., Moloney, K.A., Drobney, P., and Larson, D.L., 2010, Seeding method influences warm-season grass abundance and distribution but not local diversity in grassland restoration: Restoration Ecology, v. 18, no. s2, p. 344-353.","productDescription":"10 p.","startPage":"344","endPage":"353","numberOfPages":"10","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":256870,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://www.public.iastate.edu/~kmoloney/Instructor/Papers/2010/Yurkonis2010s.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":256875,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","volume":"18","issue":"s2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8acae4b08c986b3173a2","contributors":{"authors":[{"text":"Yurkonis, Kathryn A.","contributorId":95312,"corporation":false,"usgs":true,"family":"Yurkonis","given":"Kathryn","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":463900,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wilsey, Brian J.","contributorId":16250,"corporation":false,"usgs":true,"family":"Wilsey","given":"Brian","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":463897,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Moloney, Kirk A.","contributorId":54830,"corporation":false,"usgs":true,"family":"Moloney","given":"Kirk","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":463898,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Drobney, Pauline","contributorId":67342,"corporation":false,"usgs":true,"family":"Drobney","given":"Pauline","affiliations":[],"preferred":false,"id":463899,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Larson, Diane L. 0000-0001-5202-0634 dlarson@usgs.gov","orcid":"https://orcid.org/0000-0001-5202-0634","contributorId":2120,"corporation":false,"usgs":true,"family":"Larson","given":"Diane","email":"dlarson@usgs.gov","middleInitial":"L.","affiliations":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":463896,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}} ,{"id":70003788,"text":"70003788 - 2010 - Estimating migratory game-bird productivity by integrating age ratio and banding data","interactions":[],"lastModifiedDate":"2012-05-17T01:01:41","indexId":"70003788","displayToPublicDate":"2012-05-08T10:06:00","publicationYear":"2010","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3777,"text":"Wildlife Research","active":true,"publicationSubtype":{"id":10}},"title":"Estimating migratory game-bird productivity by integrating age ratio and banding data","docAbstract":"

Context: Reproduction is a critical component of fitness, and understanding factors that influence temporal and spatial dynamics in reproductive output is important for effective management and conservation. Although several indices of reproductive output for wide-ranging species, such as migratory birds, exist, there has been no theoretical justification for their estimators or associated measures of variance.

\n

Aims: The aims of our research were to develop statistical justification for an estimator of reproduction and associated variances on the basis of an existing national wing-collection survey and banding data, and to demonstrate the applicability of this estimator to a migratory game bird.

\n

Methods: We used a Bayesian hierarchical modelling approach to integrate wing-collection data, which provides information on population age ratios, and band-recovery data, which provides information on recovery probabilities of various age classes, for American woodcock (Scolopax minor) to estimate productivity and associated measures of variance. We present two models of relative vulnerability between age classes: one model assumed that adult recovery probabilities were higher, but that annual fluctuations were synchronous between the two age classes (i.e. an additive effect of age and year). The second model assumed that adults, on average, had higher recovery probabilities than did juveniles and that annual fluctuations were asynchronous through time (i.e. an interaction between age and year).

\n

Key results: Fitting our models within a hierarchical Bayesian framework efficiently incorporates the two data types into a single estimator and derives appropriate variances for the productivity estimator. Further, use of Bayesian methods enabled us to derive credible intervals that avoid the reliance on asymptotic assumptions. When applied to American woodcock data, the additive model resulted in biologically realistic and more precise age-ratio estimates each year and is adequate when the relative vulnerability to sampling only slightly varies or does not vary among components of a population (e.g. age, sex class) among years. Therefore, we recommend using woodcock indices from our analysis based on this model.

\n

Conclusions: We provide a flexible modelling framework for estimating productivity and associated variances that can incorporate ecological covariates to explore various factors that could drive annual dynamics in productivity. Applying our model to the American woodcock data indicated that assumptions about the variability in relative recovery probabilities could greatly influence the precision of our productivity estimator. Therefore, researchers should carefully consider the assumption of temporally variable relative recovery probabilities (i.e. ratio of juvenile to adults' recovery probability) for different age classes when applying this estimator.

\n

Implications: Several national and international management strategies for migratory game birds in North America rely on measures of productivity from harvest survey parts collections, without a justification of the estimator or providing estimates of precision. We derive an estimator of productivity with realistic measures of uncertainty that can be directly incorporated into management plans or ecological studies across large spatial scales.

Understanding how past and present water management has affected rivers is an important part of developing such tools. In this paper, we evaluate how existing hydrologic infrastructure and management affect streamflow characteristics of rivers in the Central Valley, California and discuss those characteristics in the context of habitat requirements of native and alien fishes. We evaluated the effects of water management by comparing observed discharges with estimated discharges assuming no water management (\"full natural runoff\"). Rivers in the Sacramento River drainage were characterized by reduced winter–spring discharges and augmented discharges in other months. Rivers in the San Joaquin River drainage were characterized by reduced discharges in all months but particularly in winter and spring. Two largely unaltered streams had hydrographs similar to those based on full natural runoff of the regulated rivers. The reduced discharges in the San Joaquin River drainage streams are favourable for spawning of many alien species, which is consistent with observed patterns of fish distribution and abundance in the Central Valley. However, other factors, such as water temperature, are also important to the relative success of native and alien resident fishes. As water management changes in response to climate change and societal demands, interdisciplinary programs of research and monitoring will be essential for anticipating effects on fishes and to avoid unanticipated ecological outcomes.","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.1293","usgsCitation":"Brown, L.R., and Bauer, M.L., 2010, Effects of hydrologic infrastructure on flow regimes of California's Central Valley rivers: Implications for fish populations: River Research and Applications, v. 26, no. 6, p. 751-765, https://doi.org/10.1002/rra.1293.","productDescription":"15 p.","startPage":"751","endPage":"765","numberOfPages":"15","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":254781,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":254777,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://dx.doi.org/10.1002/rra.1293","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"California","otherGeospatial":"Central Valley","volume":"26","issue":"6","noUsgsAuthors":false,"publicationDate":"2009-07-13","publicationStatus":"PW","scienceBaseUri":"505a071fe4b0c8380cd51581","contributors":{"authors":[{"text":"Brown, Larry R. 0000-0001-6702-4531 lrbrown@usgs.gov","orcid":"https://orcid.org/0000-0001-6702-4531","contributorId":1717,"corporation":false,"usgs":true,"family":"Brown","given":"Larry","email":"lrbrown@usgs.gov","middleInitial":"R.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":462658,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bauer, Marissa L.","contributorId":30359,"corporation":false,"usgs":true,"family":"Bauer","given":"Marissa","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":462659,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70038190,"text":"70038190 - 2010 - Old data, new problems","interactions":[],"lastModifiedDate":"2012-05-16T01:01:49","indexId":"70038190","displayToPublicDate":"2012-05-06T18:42:00","publicationYear":"2010","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3328,"text":"SWS Research Brief","active":true,"publicationSubtype":{"id":10}},"title":"Old data, new problems","docAbstract":"Old data are a gold standard in climate change research, and much more use should be made of these data sets to document changes in wetlands in recent decades.

These data sets include classic studies of biomass production, decomposition, vegetation composition, water level tolerances, and seed bank structure.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"SWS Research Brief","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Society of Wetland Scientists","publisherLocation":"Madison, WI","usgsCitation":"Middleton, B., 2010, Old data, new problems: SWS Research Brief, v. 2010-0002, 4 p.","productDescription":"4 p.","numberOfPages":"4","costCenters":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"links":[{"id":254783,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":254774,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://www.sws.org/ResearchBrief/Middleton_klmrev.pdf","linkFileType":{"id":5,"text":"html"}}],"country":"United States","volume":"2010-0002","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6d55e4b0c8380cd75098","contributors":{"authors":[{"text":"Middleton, Beth 0000-0002-1220-2326","orcid":"https://orcid.org/0000-0002-1220-2326","contributorId":69226,"corporation":false,"usgs":false,"family":"Middleton","given":"Beth","affiliations":[],"preferred":false,"id":463625,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70038187,"text":"70038187 - 2010 - A comparison of litter production in young and old baldcypress (Taxodium distichum L.) stands at Caddo Lake, Texas","interactions":[],"lastModifiedDate":"2012-05-12T01:01:38","indexId":"70038187","displayToPublicDate":"2012-04-01T10:29:00","publicationYear":"2010","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3534,"text":"Texas Journal of Science","active":true,"publicationSubtype":{"id":10}},"title":"A comparison of litter production in young and old baldcypress (Taxodium distichum L.) stands at Caddo Lake, Texas","docAbstract":"Aboveground primary productivity for cypress forests was assessed from measurements of litter production in two age groups and in two hydrological regimes (standing water and free-flowing). Caddo Lake, located in northeast Texas on the Texas-Louisiana border, offered a unique study site since it is dominated by extensive stands composed entirely of Taxodium distichum (L.) Rich, (baldcypress) in different age groups. Young stands (approximately 100 years old) are found along the shoreline and on shallow flooded islands. Old stands (-150 to 300 years old) are found in deeper water where they were continuously flooded. Litter production over three years from October 1998 to September 2001 was measured. Litter consisting of leaves, twigs, bark, reproductive parts, and Tillandsia usneoides (L.) L. (Spanish moss) was collected monthly using 0.5 m2 floating traps. Tree diameters were measured within 200 m2 circular plots in each stand. The young stands supported densities greater than 2,000 stems/ha and a mean stand basal area of 72.3 m2/ha, whereas old stands supported lower densities of about 500 stems/ha but with a similar mean stand basal area of 73.3 m2/ha. There was a significant difference between old and young stands for overall yearly litter production, averaging about 670 g/m2/yr in the young stands and 460 g/m2/yr in the old stands. Leaves and twigs were significantly greater in the young stands, while reproductive parts were higher in old stands. Litter collections between years or hydrological regimes were not significantly different.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Texas Journal of Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Texas Academy of Science","publisherLocation":"www.texasacademyofscience.org","usgsCitation":"McCoy, J.W., Draugelis-Dale, R.O., Keeland, B.D., and Darville, R., 2010, A comparison of litter production in young and old baldcypress (Taxodium distichum L.) stands at Caddo Lake, Texas: Texas Journal of Science, v. 62, no. 1, p. 25-40.","productDescription":"16 p.","startPage":"25","endPage":"40","numberOfPages":"15","costCenters":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"links":[{"id":254748,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Texas","otherGeospatial":"Caddo Lake","volume":"62","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e35de4b0c8380cd45fdb","contributors":{"authors":[{"text":"McCoy, John W. 0000-0003-3013-730X mccoyj@usgs.gov","orcid":"https://orcid.org/0000-0003-3013-730X","contributorId":3082,"corporation":false,"usgs":true,"family":"McCoy","given":"John","email":"mccoyj@usgs.gov","middleInitial":"W.","affiliations":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":true,"id":463620,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Draugelis-Dale, Rassa O. 0000-0001-8532-3287 daler@usgs.gov","orcid":"https://orcid.org/0000-0001-8532-3287","contributorId":20422,"corporation":false,"usgs":true,"family":"Draugelis-Dale","given":"Rassa","email":"daler@usgs.gov","middleInitial":"O.","affiliations":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":true,"id":463621,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Keeland, Bobby D.","contributorId":103506,"corporation":false,"usgs":true,"family":"Keeland","given":"Bobby","email":"","middleInitial":"D.","affiliations":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":true,"id":463623,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Darville, Roy","contributorId":91723,"corporation":false,"usgs":false,"family":"Darville","given":"Roy","email":"","affiliations":[],"preferred":false,"id":463622,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70038089,"text":"70038089 - 2010 - A new methodology for the quantitative visualization of coherent flow structures in alluvial channels using multibeam echo-sounding (MBES)","interactions":[],"lastModifiedDate":"2016-05-25T15:17:42","indexId":"70038089","displayToPublicDate":"2012-04-01T00:00:00","publicationYear":"2010","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1807,"text":"Geophysical Research Letters","active":true,"publicationSubtype":{"id":10}},"title":"A new methodology for the quantitative visualization of coherent flow structures in alluvial channels using multibeam echo-sounding (MBES)","docAbstract":"

In order to investigate the interactions between turbulence and suspended sediment transport in natural aqueous environments, we ideally require a technique that allows simultaneous measurement of fluid velocity and sediment concentration for the whole flow field. Here, we report on development of a methodology using the water column acoustic backscatter signal from a multibeam echo sounder to simultaneously quantify flow velocities and sediment concentrations. The application of this new technique is illustrated with reference to flow over the leeside of an alluvial sand dune, which allows, for the first time in a field study, quantitative visualization of large-scale, whole flow field, turbulent coherent flow structures associated with the dune leeside that are responsible for suspending bed sediment. This methodology holds great potential for use in a wide range of aqueous geophysical flows.

We coupled Bayesian model selection with linear regression splines to identify biotic or abiotic covariates with the strongest associations with abundances of each species. We then refitted change point models conditional on the selected covariates to explore whether those covariates could explain statistical trends or change points in species abundances. We also fitted a multispecies change point model that identified change points common to all species. All models included hierarchical structures to model data uncertainties, including observation errors and missing covariate values. There were step declines in abundances of all four species in the early 2000s, with a likely common decline in 2002. Abiotic variables, including water clarity, position of the 2‰ isohaline (X2), and the volume of freshwater exported from the estuary, explained some variation in species' abundances over the time series, but no selected covariates could explain statistically the post-2000 change points for any species.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Applications","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Ecological Society of America","publisherLocation":"Ithaca, NY","doi":"10.1890/09-0998.1","usgsCitation":"Thompson, J.R., Kimmerer, W.J., Brown, L.R., Newman, K.B., Mac Nally, R., Bennett, W.A., Feyrer, F., and Fleishman, E., 2010, Bayesian change point analysis of abundance trends for pelagic fishes in the upper San Francisco Estuary: Ecological Applications, v. 20, p. 1431-1448, https://doi.org/10.1890/09-0998.1.","productDescription":"18 p.","startPage":"1431","endPage":"1448","numberOfPages":"18","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":246933,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":246920,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://dx.doi.org/10.1890/09-0998.1","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"California","volume":"20","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f02ae4b0c8380cd4a611","contributors":{"authors":[{"text":"Thompson, James R.","contributorId":52015,"corporation":false,"usgs":true,"family":"Thompson","given":"James","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":462663,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kimmerer, Wim J.","contributorId":59169,"corporation":false,"usgs":false,"family":"Kimmerer","given":"Wim","email":"","middleInitial":"J.","affiliations":[{"id":6690,"text":"San Francisco State University","active":true,"usgs":false}],"preferred":false,"id":462664,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Brown, Larry R. 0000-0001-6702-4531 lrbrown@usgs.gov","orcid":"https://orcid.org/0000-0001-6702-4531","contributorId":1717,"corporation":false,"usgs":true,"family":"Brown","given":"Larry","email":"lrbrown@usgs.gov","middleInitial":"R.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":462660,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Newman, Ken B.","contributorId":51139,"corporation":false,"usgs":true,"family":"Newman","given":"Ken","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":462662,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Mac Nally, Ralph","contributorId":107966,"corporation":false,"usgs":true,"family":"Mac Nally","given":"Ralph","email":"","affiliations":[],"preferred":false,"id":462667,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Bennett, William A.","contributorId":88988,"corporation":false,"usgs":true,"family":"Bennett","given":"William","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":462665,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Feyrer, Frederick 0000-0003-1253-2349","orcid":"https://orcid.org/0000-0003-1253-2349","contributorId":106736,"corporation":false,"usgs":true,"family":"Feyrer","given":"Frederick","affiliations":[],"preferred":false,"id":462666,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Fleishman, Erica","contributorId":11863,"corporation":false,"usgs":true,"family":"Fleishman","given":"Erica","affiliations":[],"preferred":false,"id":462661,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}} ,{"id":70037764,"text":"70037764 - 2010 - Analysis of pelagic species decline in the upper San Francisco Estuary using multivariate autoregressive modeling (MAR)","interactions":[],"lastModifiedDate":"2021-01-13T16:06:21.339626","indexId":"70037764","displayToPublicDate":"2012-03-25T13:37:00","publicationYear":"2010","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1450,"text":"Ecological Applications","active":true,"publicationSubtype":{"id":10}},"title":"Analysis of pelagic species decline in the upper San Francisco Estuary using multivariate autoregressive modeling (MAR)","docAbstract":"Four species of pelagic fish of particular management concern in the upper San Francisco Estuary, California, USA, have declined precipitously since ca. 2002: delta smelt (Hypomesus transpacificus), longfin smelt (Spirinchus thaleichthys), striped bass (Morone saxatilis), and threadfin shad (Dorosoma petenense). The estuary has been monitored since the late 1960s with extensive collection of data on the fishes, their pelagic prey, phytoplankton biomass, invasive species, and physical factors. We used multivariate autoregressive (MAR) modeling to discern the main factors responsible for the declines. An expert-elicited model was built to describe the system. Fifty-four relationships were built into the model, only one of which was of uncertain direction a priori. Twenty-eight of the proposed relationships were strongly supported by or consistent with the data, while 26 were close to zero (not supported by the data but not contrary to expectations). The position of the 2‰ isohaline (a measure of the physical response of the estuary to freshwater flow) and increased water clarity over the period of analyses were two factors affecting multiple declining taxa (including fishes and the fishes' main zooplankton prey). Our results were relatively robust with respect to the form of stock–recruitment model used and to inclusion of subsidiary covariates but may be enhanced by using detailed state–space models that describe more fully the life-history dynamics of the declining species.","language":"English","publisher":"Ecological Society of America","publisherLocation":"Ithaca, NY","doi":"10.1890/09-1724.1","usgsCitation":"Mac Nally, R., Thomson, J.R., Kimmerer, W.J., Feyrer, F., Newman, K.B., Sih, A., Bennett, W.A., Brown, L.R., Fleishman, E., Culberson, S.D., and Castillo, G., 2010, Analysis of pelagic species decline in the upper San Francisco Estuary using multivariate autoregressive modeling (MAR): Ecological Applications, v. 20, no. 5, p. 1417-1430, https://doi.org/10.1890/09-1724.1.","productDescription":"14 p.","startPage":"1417","endPage":"1430","numberOfPages":"14","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":246932,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Upper San Francisco Estuary","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -122.772216796875,\n 37.77071473849609\n ],\n [\n -121.278076171875,\n 37.77071473849609\n ],\n [\n -121.278076171875,\n 38.41055825094609\n ],\n [\n -122.772216796875,\n 38.41055825094609\n ],\n [\n -122.772216796875,\n 37.77071473849609\n ]\n ]\n ]\n }\n }\n ]\n}","volume":"20","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059eb26e4b0c8380cd48c58","contributors":{"authors":[{"text":"Mac Nally, Ralph","contributorId":107966,"corporation":false,"usgs":true,"family":"Mac Nally","given":"Ralph","email":"","affiliations":[],"preferred":false,"id":462643,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Thomson, James R.","contributorId":36788,"corporation":false,"usgs":true,"family":"Thomson","given":"James","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":462634,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kimmerer, Wim J.","contributorId":59169,"corporation":false,"usgs":false,"family":"Kimmerer","given":"Wim","email":"","middleInitial":"J.","affiliations":[{"id":6690,"text":"San Francisco State University","active":true,"usgs":false}],"preferred":false,"id":462638,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Feyrer, Frederick 0000-0003-1253-2349","orcid":"https://orcid.org/0000-0003-1253-2349","contributorId":106736,"corporation":false,"usgs":true,"family":"Feyrer","given":"Frederick","affiliations":[],"preferred":false,"id":462642,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Newman, Ken B.","contributorId":51139,"corporation":false,"usgs":true,"family":"Newman","given":"Ken","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":462636,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Sih, Andy","contributorId":55247,"corporation":false,"usgs":true,"family":"Sih","given":"Andy","email":"","affiliations":[],"preferred":false,"id":462637,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Bennett, William A.","contributorId":88988,"corporation":false,"usgs":true,"family":"Bennett","given":"William","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":462641,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Brown, Larry R. 0000-0001-6702-4531 lrbrown@usgs.gov","orcid":"https://orcid.org/0000-0001-6702-4531","contributorId":1717,"corporation":false,"usgs":true,"family":"Brown","given":"Larry","email":"lrbrown@usgs.gov","middleInitial":"R.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":462639,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Fleishman, Erica","contributorId":11863,"corporation":false,"usgs":true,"family":"Fleishman","given":"Erica","affiliations":[],"preferred":false,"id":462633,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Culberson, Steven D.","contributorId":82166,"corporation":false,"usgs":true,"family":"Culberson","given":"Steven","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":462640,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Castillo, Gonzalo","contributorId":46806,"corporation":false,"usgs":true,"family":"Castillo","given":"Gonzalo","email":"","affiliations":[],"preferred":false,"id":462635,"contributorType":{"id":1,"text":"Authors"},"rank":11}]}} ,{"id":70037804,"text":"70037804 -

Generally Gray Wolves (Canis lupus L., 1758) tend to focus predation on young-of-the-year ungulates during summer, and I hypothesized that wolves preying on Muskoxen (Ovibos moschatus Zimmerman, 1780) in summer would follow that trend. Over 23 July periods observing wolves on Ellesmere Island, Nunavut, Canada, I found that packs of 2-12 adult wolves killed seven calves, one yearling, and five adult muskoxen at distances of 2.9 to 32 km from their current dens and pups. Given a possible bias against finding calves because of their fewer remains, these results do not necessarily refute the hypothesis, but they do make it clear that adult muskoxen form an important part of the wolves' diet in July and thus possibly at other times during summer.

Implementing the proposal set forth by Licht and colleagues (BioScience 60: 147–153) requires restricting wolves to tiny \"islands,\" areas that are magnitudes smaller than the ranges of most wolf populations. Wolves naturally have large ranges; restricting their spatial needs increases the risk of wolves escaping, exacerbating public relations and political and legal problems.

\n

These problems would not be solved by (a) scaring back straying radioed wolves; (b) controlling reproduction; or (c) the use of physical, virtual, or biological barriers. The problem is not wolves breeding; it is wolves killing livestock and pets, or at least people fearing they will. Standard wolf-proof barriers are 10-feet-high, chain-link fences with a 4-foot apron buried 2-feet below ground. Virtual fences, shock-collars with electrodes continually touching the skin, and frequent battery replacement are all problematic, even for captive wolves (Shivik et al. 2002). Scent-marking and howling, controls suggested by Licht and colleagues, can affect wolf movements, but our research demonstrates that trespass is common (Mech 1994).

\n

The prospects for public tolerance of such costly and intensive management seems dim anytime soon.

We describe methods of analysis that can be applied to a matrix of counts of individuals that is organized by species (rows) and time-ordered sampling periods (columns). We first developed a bootstrapping procedure to test the null hypothesis of random sampling from a stationary species abundance distribution with temporally varying sampling probabilities. This procedure can be modified to account for undetected species. We next developed a hierarchical model to estimate species-specific trends in abundance while accounting for species-specific probabilities of detection. We analysed two long-term datasets on stream fishes and grassland insects to demonstrate these methods. For both assemblages, the bootstrap test indicated that temporal trends in abundance were more heterogeneous than expected under the null model. We used the hierarchical model to estimate trends in abundance and identified sets of species in each assemblage that were steadily increasing, decreasing or remaining constant in abundance over more than a decade of standardized annual surveys. Our methods of analysis are broadly applicable to other ecological datasets, and they represent an advance over most existing procedures, which do not incorporate effects of incomplete sampling and imperfect detection.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Philosophical Transactions of the Royal Society B: Biological Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"The Royal Society","publisherLocation":"London, UK","doi":"10.1098/rstb.2010.0262","usgsCitation":"Gotelli, N., Dorazio, R.M., Ellison, A.M., and Grossman, G.D., 2010, Detecting temporal trends in species assemblages with bootstrapping procedures and hierarchical models: Philosophical Transactions of the Royal Society B: Biological Sciences, v. 365, no. 1558, p. 3621-3631, https://doi.org/10.1098/rstb.2010.0262.","productDescription":"11 p.","startPage":"3621","endPage":"3631","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":475495,"rank":101,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://nrs.harvard.edu/urn-3:HUL.InstRepos:4677617","text":"External Repository"},{"id":204858,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":204856,"rank":100,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1098/rstb.2010.0262","linkFileType":{"id":5,"text":"html"}}],"volume":"365","issue":"1558","noUsgsAuthors":false,"publicationDate":"2010-11-27","publicationStatus":"PW","scienceBaseUri":"5059ff62e4b0c8380cd4f167","contributors":{"authors":[{"text":"Gotelli, Nicholas J.","contributorId":79618,"corporation":false,"usgs":true,"family":"Gotelli","given":"Nicholas J.","affiliations":[],"preferred":false,"id":356376,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dorazio, Robert M. 0000-0003-2663-0468 bob_dorazio@usgs.gov","orcid":"https://orcid.org/0000-0003-2663-0468","contributorId":1668,"corporation":false,"usgs":true,"family":"Dorazio","given":"Robert","email":"bob_dorazio@usgs.gov","middleInitial":"M.","affiliations":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"preferred":false,"id":356373,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ellison, Aaron M.","contributorId":37058,"corporation":false,"usgs":true,"family":"Ellison","given":"Aaron","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":356375,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Grossman, Gary D.","contributorId":14106,"corporation":false,"usgs":true,"family":"Grossman","given":"Gary","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":356374,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70006217,"text":"70006217 - 2010 - Can lowland dry forests represent a refuge from avian malaria for native Hawaiian birds?","interactions":[],"lastModifiedDate":"2021-05-24T16:01:50.099791","indexId":"70006217","displayToPublicDate":"2012-02-26T14:59:00","publicationYear":"2010","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2984,"text":"Pacific Conservation Biology","active":true,"publicationSubtype":{"id":10}},"title":"Can lowland dry forests represent a refuge from avian malaria for native Hawaiian birds?","docAbstract":"Hawaii's native birds have become increasingly threatened over the past century. Introduced mosquito borne diseases such as avian malaria may be responsible for the near absence of endemic Hawaiian forest birds in low-elevation habitats. The recent recognition that some native Hawaiian forest birds may be repopulating moist lowland habitats as a result of evolved resistance to this disease has increased the conservation value of these areas. Here, we investigate whether remnant low elevation dry forests on Hawaii Island provide natural 'refuges' from mosquito-transmitted malaria by nature of their low rainfall and absence of suitable natural sources of water for mosquito breeding. Unlike lowland wet forests where high rates of disease transmission may be selecting for disease resistance, lowland dry forests may provide some refuge for native forest birds without natural resistance to malaria. We mistnetted forest birds in two lowland dry forests and tested all native birds by microscopy and serology for avian malaria caused by the Plasmodium relictum parasite. We also conducted surveys for standing water and mosquito larvae. Overall prevalence of infections with Plasmodium relictum in the Hawaii Amakihi Hemignathus virens virens was 15%. Most infected birds had lowlevel parasitemias, suggesting chronic infections. Although avian malaria is present in these lowland dry forest Amakihi populations, infection rates are significantly lower than in wet forest populations at similar elevations. Sources of breeding mosquitoes in these forests appeared to be largely anthropogenic; thus, there is potential to manage dry forests as mosquito-free habitat for Hawaii Amakihi and other Hawaiian forest birds.","language":"English","publisher":"CSIRO Publishing","doi":"10.1071/PC100181","usgsCitation":"Tucker-Mohl, K., Hart, P., and Atkinson, C.T., 2010, Can lowland dry forests represent a refuge from avian malaria for native Hawaiian birds?: Pacific Conservation Biology, v. 16, no. 3, p. 181-186, https://doi.org/10.1071/PC100181.","productDescription":"6 p.","startPage":"181","endPage":"186","costCenters":[{"id":521,"text":"Pacific Island Ecosystems Research Center","active":false,"usgs":true}],"links":[{"id":204828,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Hawai'i","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -161.0595703125,\n 18.521283325496277\n ],\n [\n -154.0283203125,\n 18.521283325496277\n ],\n [\n -154.0283203125,\n 23.241346102386135\n ],\n [\n -161.0595703125,\n 23.241346102386135\n ],\n [\n -161.0595703125,\n 18.521283325496277\n ]\n ]\n ]\n }\n }\n ]\n}","volume":"16","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f335e4b0c8380cd4b676","contributors":{"authors":[{"text":"Tucker-Mohl, Katherine","contributorId":76071,"corporation":false,"usgs":true,"family":"Tucker-Mohl","given":"Katherine","email":"","affiliations":[],"preferred":false,"id":354090,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hart, Patrick","contributorId":46691,"corporation":false,"usgs":true,"family":"Hart","given":"Patrick","affiliations":[],"preferred":false,"id":354089,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Atkinson, Carter T. 0000-0002-4232-5335 catkinson@usgs.gov","orcid":"https://orcid.org/0000-0002-4232-5335","contributorId":1124,"corporation":false,"usgs":true,"family":"Atkinson","given":"Carter","email":"catkinson@usgs.gov","middleInitial":"T.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true},{"id":5049,"text":"Pacific Islands Ecosys Research Center","active":true,"usgs":true},{"id":521,"text":"Pacific Island Ecosystems Research Center","active":false,"usgs":true}],"preferred":true,"id":354088,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ]}
