Standard survival analysis methods (e.g., accelerated failure time models) are used to assess how survival rates are influenced by disease. However, they assume that each individual is equally susceptible and will eventually experience the event of interest; this assumption is not typically satisfied with regard to pathogens of wildlife populations. In contrast, mixture cure models, which comprise logistic regression and survival analysis components, allow for different covariates to be entered into each part of the model and provide better predictions of survival when a fraction of the population is expected to survive a disease outbreak. We fitted mixture cure models to the host&ndash;pathogen dynamics of Chinook Salmon <i>Oncorhynchus tshawytscha</i> and Coho Salmon <i>O. kisutch</i> and the myxozoan parasite <i>Ceratomyxa shasta</i>. Total parasite concentration, water temperature, and discharge were used as covariates to predict the observed parasite-induced mortality in juvenile salmonids collected as part of a long-term monitoring program in the Klamath River, California. The mixture cure models predicted the observed total mortality well, but some of the variability in observed mortality rates was not captured by the models. Parasite concentration and water temperature were positively associated with total mortality and the mortality rate of both Chinook Salmon and Coho Salmon. Discharge was positively associated with total mortality for both species but only affected the mortality rate for Coho Salmon. The mixture cure models provide insights into how daily survival rates change over time in Chinook Salmon and Coho Salmon after they become infected with <i>C. shasta</i>.</p>","language":"English","publisher":"American Fisheries Society","publisherLocation":"Bethesda, MD","doi":"10.1080/00028487.2013.862183","usgsCitation":"Ray, A.R., Perry, R.W., Som, N.A., and Bartholomew, J.L., 2014, Using cure models for analyzing the influence of pathogens on salmon survival: Transactions of the American Fisheries Society, v. 143, no. 2, p. 387-398, https://doi.org/10.1080/00028487.2013.862183.","productDescription":"12 p.","startPage":"387","endPage":"398","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-063786","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":309549,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Oregon, California","otherGeospatial":"Klamath River basin, Beaver Creek","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -124.62890625,\n              39.470125122358176\n            ],\n            [\n              -119.92675781249999,\n              39.470125122358176\n            ],\n            [\n              -119.92675781249999,\n              43.229195113965005\n            ],\n            [\n              -124.62890625,\n              43.229195113965005\n            ],\n            [\n              -124.62890625,\n              39.470125122358176\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"143","issue":"2","publishingServiceCenter":{"id":12,"text":"Tacoma PSC"},"noUsgsAuthors":false,"publicationDate":"2014-03-03","publicationStatus":"PW","scienceBaseUri":"56139f57e4b0ba4884c60fd1","contributors":{"authors":[{"text":"Ray, Adam R","contributorId":148959,"corporation":false,"usgs":false,"family":"Ray","given":"Adam","email":"","middleInitial":"R","affiliations":[{"id":17603,"text":"Department of Fisheries and Wildlife, Oregon State University, 104 Nash Hall, 2820 Southwest Campus Way, Corvallis, OR  97331","active":true,"usgs":false}],"preferred":false,"id":576264,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Perry, Russell W. 0000-0003-4110-8619 rperry@usgs.gov","orcid":"https://orcid.org/0000-0003-4110-8619","contributorId":2820,"corporation":false,"usgs":true,"family":"Perry","given":"Russell","email":"rperry@usgs.gov","middleInitial":"W.","affiliations":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"preferred":true,"id":576263,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Som, Nicholas A.","contributorId":36039,"corporation":false,"usgs":true,"family":"Som","given":"Nicholas","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":576265,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bartholomew, Jerri L","contributorId":148960,"corporation":false,"usgs":false,"family":"Bartholomew","given":"Jerri","email":"","middleInitial":"L","affiliations":[{"id":17604,"text":"Dept. of Microbiology, OSU, 220 Nash Hall, 2820 Southwest Campus Way, Corvallis, OR  97331","active":true,"usgs":false}],"preferred":false,"id":576266,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

However, in many areas we do not know if mayflies were native/endemic and thus, whether recovery is a logical measure to assess progress of recovery. In the present study, we construct a chronologic record of relative abundance of burrowing mayflies in Saginaw Bay by the use of mayfly tusks and radionuclides in sediments (i.e., a paleoecologic record) and historic records of mayfly nymphs in the bay. These records reveal that mayflies: (1) were few before 1799, which indicates that nymphs were probably native/endemic in the bay, (2) increased between 1799 and 1807 and remained at relatively high levels between 1807 and 1965, probably in response to increased nutrient run-off from the watershed, (3) declined dramatically between 1965 and 1973, probably as a result of excessive eutrophication in the mid-1950s; and, (4) were few and highly variable between 1973 and 2001, probably as a result of low and unstable abundances of mayfly nymphs. Historic records verify that nymphs disappeared in the bay in the late-1950s to early-1960s which is in agreement with the paleoecologic record. Reoccurrence of low abundances of nymphs in the bay between 1991 and 2008 and comparison of chronologic records of nymphs in Saginaw Bay and western Lake Erie suggest that mayflies may return to Saginaw Bay in the early-21st century. Undoubtedly, watershed conservation and three decades of pollution abatement have set the stage for a recovery of burrowing mayflies in Saginaw Bay, and possibly in other areas of the Great Lakes.</p>","language":"English","publisher":"International Association for Great Lakes Research","publisherLocation":"Toronto","doi":"10.1016/j.jglr.2013.12.016","usgsCitation":"Schloesser, D.W.,

The origins of pertinent hypotheses, current understanding and gaps in our knowledge are highlighted with reference to biogeographic, geographic and socio-economic influences.</p>\n\n<br>\n\n<p>Results</p>\n<p>The role of mangroves as C sinks needs to be evaluated for a wide range of biogeographic regions and forest conditions. Mangrove C assimilation may be under-estimated because of flawed methodology and scanty data on key components of C dynamics. Peri-urban mangroves may be manipulated to provide local offsets for C emission. The nursery function of mangroves is not ubiquitous but varies with spatio-temporal accessibility. Connectivity and complementarity of mangroves and adjacent habitats enhance their nursery function through trophic relay and ontogenetic migrations. The effectiveness of mangroves for coastal protection depends on factors at landscape/geomorphic to community scales and local/species scales. Shifts in species due to climate change, forest degradation and loss of habitat connectivity may reduce the protective capacity of mangroves. Early views of mangroves as land builders (especially lateral expansion) were questionable. Evidence now indicates that mangroves, once established, directly influence vertical land development by enhancing sedimentation and/or by direct organic contributions to soil volume (peat formation) in some settings.</p>\n\n<br>\n\n<p>Main conclusions</p>\n<p>Knowledge of thresholds, spatio-temporal scaling and variability due to geographic, biogeographic and socio-economic settings will improve the management of mangrove ecosystem services. Many drivers respond to global trends in climate change and local changes such as urbanization. While mangroves have traditionally been managed for subsistence, future governance models must involve partnerships between local custodians of mangroves and offsite beneficiaries of the services.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Global Ecology and Biogeography","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Global Ecology and Biogeography","doi":"10.1111/geb.12155","usgsCitation":"Lee, S.Y., Primavera, J., Dahdouh-Guebas, F., McKee, K., Bosire, J.O., Cannicci, S., Diele, K., Fromard, F., Koedam, N., Marchand, C., Mendelssohn, I., Mukherjee, N., and Record, S., 2014, Ecological role and services of tropical mangrove ecosystems: a reassessment: Global Ecology and Biogeography, v. 23, no. 7, p. 726-743, https://doi.org/10.1111/geb.12155.","productDescription":"18 p.","startPage":"726","endPage":"743","numberOfPages":"18","ipdsId":"IP-045539","costCenters":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"links":[{"id":473128,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/geb.12155","text":"Publisher Index Page"},{"id":283868,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":283867,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/geb.12155"}],"country":"United States","volume":"23","issue":"7","noUsgsAuthors":false,"publicationDate":"2014-03-06","publicationStatus":"PW","scienceBaseUri":"53517035e4b05569d805a1da","contributors":{"authors":[{"text":"Lee, Shing Yip","contributorId":39694,"corporation":false,"usgs":false,"family":"Lee","given":"Shing","email":"","middleInitial":"Yip","affiliations":[{"id":13193,"text":"School of Environment, Griffith University","active":true,"usgs":false}],"preferred":false,"id":486562,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Primavera, Jurgene H.","contributorId":56151,"corporation":false,"usgs":true,"family":"Primavera","given":"Jurgene H.","affiliations":[],"preferred":false,"id":486564,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dahdouh-Guebas, Farid","contributorId":30138,"corporation":false,"usgs":true,"family":"Dahdouh-Guebas","given":"Farid","affiliations":[],"preferred":false,"id":486561,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"McKee, Karen 0000-0001-7042-670X","orcid":"https://orcid.org/0000-0001-7042-670X","contributorId":89592,"corporation":false,"usgs":true,"family":"McKee","given":"Karen","affiliations":[],"preferred":false,"id":486568,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Bosire, Jared O.","contributorId":48096,"corporation":false,"usgs":true,"family":"Bosire","given":"Jared","email":"","middleInitial":"O.","affiliations":[],"preferred":false,"id":486563,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Cannicci, Stefano","contributorId":69884,"corporation":false,"usgs":true,"family":"Cannicci","given":"Stefano","email":"","affiliations":[],"preferred":false,"id":486566,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Diele, Karen","contributorId":104398,"corporation":false,"usgs":true,"family":"Diele","given":"Karen","affiliations":[],"preferred":false,"id":486571,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Fromard, Francois","contributorId":89801,"corporation":false,"usgs":true,"family":"Fromard","given":"Francois","email":"","affiliations":[],"preferred":false,"id":486569,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Koedam, Nico","contributorId":99463,"corporation":false,"usgs":true,"family":"Koedam","given":"Nico","email":"","affiliations":[],"preferred":false,"id":486570,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Marchand, Cyril","contributorId":62136,"corporation":false,"usgs":true,"family":"Marchand","given":"Cyril","email":"","affiliations":[],"preferred":false,"id":486565,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Mendelssohn, Irving","contributorId":21455,"corporation":false,"usgs":true,"family":"Mendelssohn","given":"Irving","affiliations":[],"preferred":false,"id":486559,"contributorType":{"id":1,"text":"Authors"},"rank":11},{"text":"Mukherjee, Nibedita","contributorId":85086,"corporation":false,"usgs":true,"family":"Mukherjee","given":"Nibedita","email":"","affiliations":[],"preferred":false,"id":486567,"contributorType":{"id":1,"text":"Authors"},"rank":12},{"text":"Record, Sydne","contributorId":23844,"corporation":false,"usgs":true,"family":"Record","given":"Sydne","email":"","affiliations":[],"preferred":false,"id":486560,"contributorType":{"id":1,"text":"Authors"},"rank":13}]}}

Although others have conducted extensive studies on trout-perch ecology, those efforts predated invasions of white perch <i>Morone americana</i>, <i>Dreissena</i> spp., <i>Bythotrephes longimanus</i> and round goby <i>Neogobius melanostomus</i>, suggesting the need to revisit past work. Trout-perch were sampled with bottom trawls at 56 sites during June and September 2010. We examined diets, fecundity, average annual mortality, sex ratio, and long-term population trends at sites sampled since 1961. Trout-perch abundance fluctuated periodically, with distinct shorter- (4-year) and longer-term (over period of 50 years) fluctuations. Males had higher average annual mortality than females. Both sexes were equally abundant at age 0, but females outnumbered males 4:1 by age 2. Diets of trout-perch were dominated by macroinvertebrates, particularly chironomids and <i>Hexagenia</i> sp. Size distributions of trout-perch eggs varied widely and exhibited multiple modes indicative of protracted batch spawning. A review of the few other studies of trout-perch revealed periodic fluctuations in sex ratio of adults, which in light of our evidence of periodicity in abundance suggests the potential for sex-ratio-mediated intrinsic population regulation. Despite the introduction of numerous invasive species in Lake Erie, trout-perch remain one of the most abundant benthic invertivores and the population is relatively stable.</p>","language":"English","publisher":"International Association for Great Lakes Research","publisherLocation":"Toronto","doi":"10.1016/j.jglr.2013.09.004","usgsCitation":"Kocovsky, P.,

The sequence-stratigraphic architecture of the lower part of the Sunwaptan Stage at the base of the Tunnel City Group, at the contact between the Wonewoc Formation and Lone Rock Formation, records the first part of complex polyphase flooding (Sauk III) of the Laurentian craton, at a scale smaller than most events recorded by global sea-level curves. Flat-pebble conglomerate and glauconite document transgressive ravinement and development of a condensed section when creation of accommodation exceeded its consumption by sedimentation. Thinly-bedded, fossiliferous sandstone represents the most distal setting during earliest highstand. Subsequent deposition of sandstone characterized by hummocky or trough cross-stratification records progradational pulses of shallower, storm- and wave-dominated environments across the craton before final flooding of Sauk III commenced with carbonate deposition during the middle part of the Sunwaptan Stage. Comparison of early Sunwaptan flooding of the inner Laurentian craton to published interpretations from other parts of North America suggests that Sauk III was not a single, long-term accommodation event as previously proposed.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Sedimentary Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.sedgeo.2013.09.007","usgsCitation":"Eoff, J.D., 2014, Sequence stratigraphy of the Upper Cambrian (Furongian; Jiangshanian and Sunwaptan) Tunnel City Group, Upper Mississippi Valley: Transgressing assumptions of cratonic flooding: Sedimentary Geology, v. 302, p. 87-101, https://doi.org/10.1016/j.sedgeo.2013.09.007.","productDescription":"15 p.","startPage":"87","endPage":"101","ipdsId":"IP-045324","costCenters":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":283357,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":283356,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.sedgeo.2013.09.007"}],"country":"United States","state":"Minnesota;Wisconsin","otherGeospatial":"Tunnel City Group;Upper Mississippi Valley","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -93.68,42.67 ], [ -93.68,45.47 ], [ -89.09,45.47 ], [ -89.09,42.67 ], [ -93.68,42.67 ] ] ] } } ] }","volume":"302","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53517060e4b05569d805a39e","contributors":{"authors":[{"text":"Eoff, Jennifer D. jeoff@usgs.gov","contributorId":3418,"corporation":false,"usgs":true,"family":"Eoff","given":"Jennifer","email":"jeoff@usgs.gov","middleInitial":"D.","affiliations":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":486145,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The catch per\nunit effort of adult lake trout in gill nets increased each year from 2008-2013, recovering from historic\nlows recorded during 2005-2007. Adult abundance in 2013 exceeded the level of the 1999-2004 mean\nwhich at the time appeared to be the new stable abundance following from the 1993 stocking cuts. The\n2013 rate of wounding by sea lamprey (<i>Petromyzon marinus</i>) on lake trout caught in gill nets was 2.26\nfresh (A1) wounds per 100 lake trout and was slightly above target (2 wounds per 100 lake trout).\nEstimates from the NYSDEC fishing boat survey indicated 2013 angler catch and harvest rates were the\nhighest estimated in more than 10 years. Adult lake trout condition (indexed from annual length–weight\nregressions) increased in 2007-2009 from relatively low values observed during 2000-2006, remained\nnearly constant during 2010-2012 at the highest values observed for the 30 year time-series, but declined\nin 2013. The low condition values observed for juvenile lake trout during 2010-2012 continued during\n2013. Reproductive potential for the adult stock, determined from the annual egg deposition index,\nrebounded from the 2007-2008 values that were the lowest observed since 1985 and stabilized during\n2009-2013 at a mean value of 20.7. In 2013, five age-1 and three age-2 naturally produced lake trout\nwere collected from trawl survey catches providing first evidence of a 2012 year class and continued\nevidence of a 2011 year

For nutrient-limited plants, eutrophication has either reduced or stimulated belowground biomass depending on plant biomass allocation response to fertilization. Within a freshwater wetland impoundment receiving minimal sediments, we used experimental plots to explore growth models for a common freshwater macrophyte, Schoenoplectus acutus. We used N-addition and control plots (4 each) to test whether remotely sensed vegetation indices could predict leaf N concentration, root:shoot ratios and belowground biomass of S. acutus. Following 5 months of summer growth, we harvested whole plants, measured leaf N and total plant biomass of all above and belowground vegetation. Prior to harvest, we simulated measurement of plant spectral reflectance over 164 hyperspectral Hyperion satellite bands (350–2500 nm) with a portable spectroradiometer. N-addition did not alter whole plant, but reduced belowground biomass 36% and increased aboveground biomass 71%. We correlated leaf N concentration with known N-related spectral regions using all possible normalized difference (ND), simple band ratio (SR) and first order derivative ND (FDN) and SR (FDS) vegetation indices. FDN<sub>1235, 549</sub> was most strongly correlated with leaf N concentration and also was related to belowground biomass, the first demonstration of spectral indices and belowground biomass relationships. While S. acutus exhibited balanced growth (reduced root:shoot ratio with respect to nutrient addition), our methods also might relate N-enrichment to biomass point estimates for plants with isometric root growth. For isometric growth, foliar N indices will scale equivalently with above and belowground biomass. Leaf N vegetation indices should aid in scaling-up field estimates of biomass and assist regional monitoring.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"PLoS ONE","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"PLoS One","doi":"10.1371/journal.pone.0090870","usgsCitation":"O’Connell, J.L., Byrd, K.B., and Kelly, M., 2014, Remotely-sensed indicators of N-related biomass allocation in Schoenoplectus acutus: PLoS ONE, v. 9, no. 3, e90870; 9 p., https://doi.org/10.1371/journal.pone.0090870.","productDescription":"e90870; 9 p.","ipdsId":"IP-043801","costCenters":[{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"links":[{"id":473129,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pone.0090870","text":"Publisher Index Page"},{"id":283864,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":283863,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1371/journal.pone.0090870"}],"country":"United States","state":"California","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.0533,37.7394 ], [ -122.0533,38.3794 ], [ -121.4133,38.3794 ], [ -121.4133,37.7394 ], [ -122.0533,37.7394 ] ] ] } } ] }","volume":"9","issue":"3","noUsgsAuthors":false,"publicationDate":"2014-03-10","publicationStatus":"PW","scienceBaseUri":"5351705fe4b05569d805a390","contributors":{"authors":[{"text":"O’Connell, Jessica L.","contributorId":62518,"corporation":false,"usgs":true,"family":"O’Connell","given":"Jessica","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":487890,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Byrd, Kristin B. 0000-0002-5725-7486 kbyrd@usgs.gov","orcid":"https://orcid.org/0000-0002-5725-7486","contributorId":3814,"corporation":false,"usgs":true,"family":"Byrd","given":"Kristin","email":"kbyrd@usgs.gov","middleInitial":"B.","affiliations":[{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"preferred":true,"id":487888,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kelly, Maggi","contributorId":14275,"corporation":false,"usgs":true,"family":"Kelly","given":"Maggi","affiliations":[],"preferred":false,"id":487889,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Composite anomalies of the NCEP-driven RegCM3 simulations for 1982–2000 indicate that the regional model is capable of accurately simulating the key features (500-hPa heights, surface temperature, and precipitation) of the positive and negative phases of the PNA with little loss of information in the downscaling process. The basic structure of the PNA is captured in both the ECHAM5 global and ECHAM5-driven RegCM3 simulations. The 1950–2000 ECHAM5 simulation displays similar temporal and spatial variability in the PNA index as that of NCEP; however, the magnitudes of the positive and negative phases are weaker than those of NCEP. The RegCM3 simulations clearly differentiate the climatology and associated anomalies of snow water equivalent and soil moisture of the positive and negative PNA phases. In the RegCM3 simulations of the future (2050–2100), changes in the location and extent of the Aleutian low and the continental high over North America alter the dominant flow patterns associated with positive and negative PNA modes. The future projections display a shift in the patterns of the relationship between the PNA and surface climate variables, which suggest the potential for changes in the PNA-related surface hydrology of North America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Climate Dynamics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.1007/s00382-013-1910-x","usgsCitation":"Allan, A.M., Hostetler, S.W., and Alder, J.R., 2014, Analysis of the present and future winter Pacific-North American teleconnection in the ECHAM5 global and RegCM3 regional climate models: Climate Dynamics, v. 42, no. 5-6, p. 1671-1682, https://doi.org/10.1007/s00382-013-1910-x.","productDescription":"12 p.","startPage":"1671","endPage":"1682","numberOfPages":"12","ipdsId":"IP-049534","costCenters":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"links":[{"id":295469,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":295465,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00382-013-1910-x"}],"otherGeospatial":"North America, North Pacific","volume":"42","issue":"5-6","noUsgsAuthors":false,"publicationDate":"2013-08-18","publicationStatus":"PW","scienceBaseUri":"54422f9be4b0192a5a42f3ce","contributors":{"authors":[{"text":"Allan, Andrea M.","contributorId":24714,"corporation":false,"usgs":true,"family":"Allan","given":"Andrea","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":503509,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hostetler, Steven W. 0000-0003-2272-8302 swhostet@usgs.gov","orcid":"https://orcid.org/0000-0003-2272-8302","contributorId":3249,"corporation":false,"usgs":true,"family":"Hostetler","given":"Steven","email":"swhostet@usgs.gov","middleInitial":"W.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true},{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"preferred":true,"id":503507,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Alder, Jay R. 0000-0003-2378-2853 jalder@usgs.gov","orcid":"https://orcid.org/0000-0003-2378-2853","contributorId":5118,"corporation":false,"usgs":true,"family":"Alder","given":"Jay","email":"jalder@usgs.gov","middleInitial":"R.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true},{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":503508,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

However, the concept of ecological thresholds has not been widely incorporated or adopted in management goals. This largely stems from the uncertainty revolving around threshold levels and the post hoc analyses that have generally been used to identify them. Natural resource managers have a need for new tools and approaches that will help them assess the existence and detection of conditions that demand management actions. Recognition of additional threshold concepts include: utility thresholds (which are based on human values about ecological systems) and decision thresholds (which reflect management objectives and values and include ecological knowledge about a system) as well as ecological thresholds. All of these concepts provide a framework for considering the use of threshold concepts in natural resource decision making.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Application of threshold concepts in natural resource decision making","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Springer","doi":"10.1007/978-1-4899-8041-0_1","usgsCitation":"Guntenspergen, G.R., and Gross, J., 2014, Threshold concepts: implications for the management of natural resources, chap. <i>of</i> Application of threshold concepts in natural resource decision making, p. 1-7, https://doi.org/10.1007/978-1-4899-8041-0_1.","productDescription":"7 p.","startPage":"1","endPage":"7","ipdsId":"IP-051869","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":285877,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":285116,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/978-1-4899-8041-0_1"},{"id":284320,"type":{"id":15,"text":"Index Page"},"url":"https://link.springer.com/chapter/10.1007/978-1-4899-8041-0_1"}],"noUsgsAuthors":false,"publicationDate":"2014-02-08","publicationStatus":"PW","scienceBaseUri":"5351706ae4b05569d805a40c","contributors":{"authors":[{"text":"Guntenspergen, Glenn R. 0000-0002-8593-0244 glenn_guntenspergen@usgs.gov","orcid":"https://orcid.org/0000-0002-8593-0244","contributorId":2885,"corporation":false,"usgs":true,"family":"Guntenspergen","given":"Glenn","email":"glenn_guntenspergen@usgs.gov","middleInitial":"R.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":491828,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gross, John","contributorId":19876,"corporation":false,"usgs":true,"family":"Gross","given":"John","affiliations":[],"preferred":false,"id":491829,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

However, the underlying conditions of emergence and spread of avian influenza viruses (AIV) have not been studied in detail, particularly the complex spatiotemporal interplay of viral transmission between wild and domestic ducks, two major actors of AIV epidemiology. In this synthesis, we examine the risks of avian influenza spread in Poyang Lake, an area of intensive free-ranging duck production and large numbers of wild waterfowl. Our synthesis shows that farming of free-grazing domestic ducks is intensive in this area and synchronized with wild duck migration. The presence of juvenile domestic ducks in harvested paddy fields prior to the arrival and departure of migrant ducks in the same fields may amplify the risk of AIV circulation and facilitate the transmission between wild and domestic populations. We provide evidence associating wild ducks migration with the spread of H5N1 in the spring of 2008 from southern China to South Korea, Russia, and Japan, supported by documented wild duck movements and phylogenetic analyses of highly pathogenic avian influenza H5N1 sequences. We suggest that prevention measures based on a modification of agricultural practices may be implemented in these areas to reduce the intensity of AIV transmission between wild and domestic ducks. This would require involving all local stakeholders to discuss feasible and acceptable solutions.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"EcoHealth","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.1007/s10393-014-0914-2","usgsCitation":"Cappelle, J., Zhao, D., Gilbert, M., Newman, S.H., Takekawa, J.Y., Gaidet, N., Prosser, D.J., Liu, Y., Li, P., Shu, Y., and Xiao, X., 2014, Risks of avian influenza transmission in areas of intensive free-ranging duck production with wild waterfowl: EcoHealth, v. 11, no. 1, p. 109-119, https://doi.org/10.1007/s10393-014-0914-2.","productDescription":"11 p.","startPage":"109","endPage":"119","numberOfPages":"11","ipdsId":"IP-041542","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":473130,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/4047217","text":"External Repository"},{"id":293844,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":293781,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10393-014-0914-2"}],"country":"China","otherGeospatial":"Poyang Lake","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 115.1671,28.1759 ], [ 115.1671,29.76 ], [ 116.755,29.76 ], [ 116.755,28.1759 ], [ 115.1671,28.1759 ] ] ] } } ] }","volume":"11","issue":"1","noUsgsAuthors":false,"publicationDate":"2014-03-21","publicationStatus":"PW","scienceBaseUri":"54140b27e4b082fed288b96c","contributors":{"authors":[{"text":"Cappelle, Julien","contributorId":71440,"corporation":false,"usgs":true,"family":"Cappelle","given":"Julien","email":"","affiliations":[],"preferred":false,"id":500878,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Zhao, Delong","contributorId":74686,"corporation":false,"usgs":true,"family":"Zhao","given":"Delong","email":"","affiliations":[],"preferred":false,"id":500880,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gilbert, Marius","contributorId":61148,"corporation":false,"usgs":true,"family":"Gilbert","given":"Marius","email":"","affiliations":[],"preferred":false,"id":500875,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Newman, Scott H.","contributorId":101372,"corporation":false,"usgs":true,"family":"Newman","given":"Scott","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":500881,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Takekawa, John Y. 0000-0003-0217-5907 john_takekawa@usgs.gov","orcid":"https://orcid.org/0000-0003-0217-5907","contributorId":176168,"corporation":false,"usgs":true,"family":"Takekawa","given":"John","email":"john_takekawa@usgs.gov","middleInitial":"Y.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":false,"id":500871,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Gaidet, Nicolas","contributorId":37601,"corporation":false,"usgs":true,"family":"Gaidet","given":"Nicolas","email":"","affiliations":[],"preferred":false,"id":500874,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Prosser, Diann J. 0000-0002-5251-1799 dprosser@usgs.gov","orcid":"https://orcid.org/0000-0002-5251-1799","contributorId":2389,"corporation":false,"usgs":true,"family":"Prosser","given":"Diann","email":"dprosser@usgs.gov","middleInitial":"J.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":500872,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Liu, Ying","contributorId":11130,"corporation":false,"usgs":true,"family":"Liu","given":"Ying","affiliations":[],"preferred":false,"id":500873,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Li, Peng","contributorId":72642,"corporation":false,"usgs":true,"family":"Li","given":"Peng","affiliations":[],"preferred":false,"id":500879,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Shu, Yuelong","contributorId":61760,"corporation":false,"usgs":true,"family":"Shu","given":"Yuelong","email":"","affiliations":[],"preferred":false,"id":500876,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Xiao, Xiangming","contributorId":67212,"corporation":false,"usgs":true,"family":"Xiao","given":"Xiangming","affiliations":[],"preferred":false,"id":500877,"contributorType":{"id":1,"text":"Authors"},"rank":11}]}}

The NCCS is located within one of the world’s four major eastern boundary currents and is characterized by an abundant and diverse marine ecosystem fuelled seasonally by wind-driven upwelling which supplies nutrient-rich water to abundant phytoplankton inhabiting the surface euphotic zone. The oceanographic conditions throughout the NCCS fluctuate according to well-described seasonal, inter-annual, and decadal cycles. Such oceanographic variability can influence patterns in the distribution, abundance, and habitat use among marine birds and mammals. Although there are an increasing number of studies documenting distributions and abundances among birds and mammals in various portions of the NCCS, there have been no comprehensive, large-scale, multi-seasonal surveys completed throughout this region since the early 1980s (off northern California; Briggs et al. 1987) and early 1990s (off Oregon and Washington; Bonnell et al. 1992, Briggs et al. 1992, Green et al. 1992). During 2011 and 2012, we completed the Pacific Continental Shelf Environmental Assessment (PaCSEA) which included replicated surveys over the continental shelfslope from shore to the 2000-meter (m) isobath along 32 broad-scale transects from Fort Bragg, California (39° N) through Grays Harbor, Washington (47° N). Additionally, surveys at a finer scale were conducted over the continental shelf within six designated Focal Areas: Fort Bragg, CA; Eureka, CA; Siltcoos Bank, OR; Newport, OR; Nehalem Bank, OR; and Grays Harbor, WA. We completed a total of 26,752 km of standardized, low-elevation aerial survey effort across three bathymetric domains: inner-shelf waters (<100-m depth), outer shelf waters (100 – 200-m depth) and continental slope waters (200 – 2000-m depth). Survey effort was similar among seasons (winter, summer, and fall) and between years and varied according to the three bathymetric domains: 47% (12,646 km) covered the continental slope, 33% (8887 km) covered the inner-shelf (0 – 100-m depth), and 20% (5,219 km) covered the outer-shelf.</p>\n<br>\n<p>Overall, we recorded 15,403 sightings of 59,466 individual marine birds (12 families, 54 species). During winter, seven species groupings comprised >90% of the total number of birds counted (19,033) with Common Murres (Uria aalge) representing the majority of individuals counted (70.4% of total). The remaining six most abundant taxa included: Surf/White-winged Scoters (Melanitta perspicillata/M. fusca; 4.8% of total), Herring/Thayer’s Gulls (Larus argentatus/L. thayeri; 3.8% of total), Cassin’s Auklets (Ptychoramphus aleuticus; 3.8% of total), Glaucous-winged Gulls (Larus glaucescens; 3.7% of total), Black-legged Kittiwakes (Rissa tridactyla; 2.0% of total), and Western Gulls (Larus occidentalis; 1.9% of total). During summer, five species comprised >95% of the total number of birds counted (17,063) with the majority comprised of Common Murres (54.1% of total) and Sooty Shearwaters (Puffinus griseus; 34.4% of total). The remaining most abundant three taxa included: Fork-tailed Storm-Petrels (Oceanodroma furcata; 3.3% of total), Western Gulls (2.1% of total), and Leach’s Storm-Petrels (Oceanodroma leucorhoa; 1.1% of total). During fall, nine species comprised >85% of the total number of birds counted (23,376) with the majority comprised of Common Murres (50.0% of total) and Sooty Shearwaters (10.5% of total). The remaining seven taxa included Cassin’s Auklets (5.2% of total), Surf/White-winged Scoters (5.1% of total), Fork-tailed Storm-Petrels (3.8% of total), Red/Red-necked Phalaropes (Phalaropus fulicarius/P. lobatus; 3.2% of total), California Gulls (Larus californicus; 3.1% of total), Northern Fulmars (Fulmarus glacialis; 2.7% of total), and Sabine’s Gulls (Xema sabini; 2.2% of total). Throughout the entire PaCSEA survey area, average densities (± SE) at sea for all marine birds combined were similar between fall (23.7 ± 1.9 birds km<sup>-2</sup>) and winter (24.0 ± 1.9 birds km<sup>-2</sup>) and least during summer (16.3 ± 2.2 birds km<sup>-2</sup>). Marine bird densities at sea varied according to bathymetric domain and season. Throughout the entire PaCSEA study area average densities (± SE) for all marine birds combined were greatest over the inner-shelf domain (<100-m depth) during fall (49.4 ± 5.0 birds km<sup>-2</sup>) and similar during winter (37.4 ± 4.6 birds km<sup>-2</sup>) and summer (37.5 ± 6.4 birds km<sup>-2</sup>). Within the outer-shelf domain (100 – 200-m depth), average densities for all marine birds combined were greatest during winter (34.6 ± 4.2 birds km-2), lesser during fall (16.2 ± 1.7 birds km-2), and least during summer (6.9 ± 1.1 birds km-2). Within the farthest offshore waters over the continental slope domain (200 – 2000-m depth) average densities for all marine birds combined were greatest during fall (10.0 ± 2.2 birds km<sup>-2</sup>) and winter (9.3 ± 1.5 birds km<sup>-2</sup>), and lesser during summer (6.2 ± 1.4 birds km<sup>-2</sup>).</p>\n<br>\n<p>We observed 16 cetacean species and five pinniped species. Among the Mysticeti (baleen whales), humpback whales (Megaptera novaeangliae) were most frequently observed (114 sightings of 264 individuals) during summer and fall mostly over the outer-shelf and slope waters, however, individuals were also seen within the Siltcoos, Nehalem, Fort Bragg, and Eureka Focal Areas. We recorded 11 Odontoceti (toothed whale) species. Harbor porpoises (Phocoena phocoena) were the most frequently sighted (164 sightings of 270 individuals). Harbor porpoises were present year-round and most frequently sighted within the inner-shelf domain throughout the entire study area in all seasons. Harbor porpoises occurred in all six Focal Areas, with noteworthy aggregations within the Eureka, Siltcoos, and Grays Harbor Focal Areas.</p>\n<br>\n<p>We recorded 246 sightings of 375 individual pinnipeds (5 species). California sea lions (Zalophus californianus) were the most frequently sighted and were present year-round with slightly more sightings recorded during the fall. California sea lions showed a decreasing frequency of sightings and relative abundance with distance from shore across the bathymetric domains surveyed, being most frequently observed over the inner-shelf. Northern elephant seals (Mirounga angustirostris), harbor seals (Phoca vitulina), and northern fur seals (Callorhinus ursinus) were observed occasionally during all seasons with harbor seals occurring nearshore (usually within 10 km of the coast) and northern fur seals almost exclusively beyond the shelf break (> 200-m depth), especially during winter off Oregon and Washington. Northern (Steller’s) sea lions (Eumetopias jubatus) were uncommonly sighted during winter and fall.</p>","language":"English","publisher":"Bureau of Ocean Energy Management","collaboration":"Prepared under Interagency Agreement M10PG00081","usgsCitation":"Adams, J., Felis, J.J., Mason, J.W., and Takekawa, J.Y., 2014, Pacific Continental Shelf Environmental Assessment (PaCSEA): aerial seabird and marine mammal surveys off northern California, Oregon, and Washington, 2011-2012: BOEM 2014-003, viii, 257 p.","productDescription":"viii, 257 p.","numberOfPages":"266","temporalStart":"2011-01-01","temporalEnd":"2012-12-31","ipdsId":"IP-054329","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":287701,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":285205,"type":{"id":11,"text":"Document"},"url":"https://www.boem.gov/2014-003/"}],"country":"United States","state":"California;Oregon;Washington","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -127.0,39.0 ], [ -127.0,47.0 ], [ -119.0,47.0 ], [ -119.0,39.0 ], [ -127.0,39.0 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53870570e4b0aa26cd7b53e7","contributors":{"authors":[{"text":"Adams, Josh 0000-0003-3056-925X josh_adams@usgs.gov","orcid":"https://orcid.org/0000-0003-3056-925X","contributorId":2422,"corporation":false,"usgs":true,"family":"Adams","given":"Josh","email":"josh_adams@usgs.gov","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":492208,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Felis, Jonathan J. 0000-0002-0608-8950 jfelis@usgs.gov","orcid":"https://orcid.org/0000-0002-0608-8950","contributorId":4825,"corporation":false,"usgs":true,"family":"Felis","given":"Jonathan","email":"jfelis@usgs.gov","middleInitial":"J.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":492209,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mason, John W.","contributorId":42881,"corporation":false,"usgs":false,"family":"Mason","given":"John","email":"","middleInitial":"W.","affiliations":[{"id":6913,"text":"Wisconsin Department of Natural Resources","active":true,"usgs":false}],"preferred":false,"id":492210,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Takekawa, John Y. 0000-0003-0217-5907 john_takekawa@usgs.gov","orcid":"https://orcid.org/0000-0003-0217-5907","contributorId":176168,"corporation":false,"usgs":true,"family":"Takekawa","given":"John","email":"john_takekawa@usgs.gov","middleInitial":"Y.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":false,"id":492207,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Therefore, assessing resource selection by these avian scavengers requires quantifying the availability of terrestrial-based habitats, as well as meteorological variables that influence atmospheric conditions necessary for soaring. In this study, we undertook the first quantitative assessment of habitat- and meteorological-based resource selection in the endangered California condor (<i>Gymnogyps californianu</i>s) within its California range and across the annual cycle. We found that condor use of terrestrial areas did not change markedly within the annual cycle, and that condor use was greatest for habitats where food resources and potential predators could be detected and where terrain was amenable for taking off from the ground in flight (e.g., sparse habitats, coastal areas). Condors originating from different release sites differed in their use of habitat, but this was likely due in part to variation in habitats surrounding release sites. Meteorological conditions were linked to condor use of ecological subregions, with thermal height, thermal velocity, and wind speed having both positive (selection) and negative (avoidance) effects on condor use in different areas. We found little evidence of systematic effects between individual characteristics (i.e., sex, age, breeding status) or components of the species management program (i.e., release site, rearing method) relative to meteorological conditions. Our findings indicate that habitat type and meteorological conditions can interact in complex ways to influence condor resource selection across landscapes, which is noteworthy given the extent of anthropogenic stressors that may impact condor populations (e.g., lead poisoning, wind energy development). Additional studies will be valuable to assess small-scale condor movements in light of these stressors to help minimize their risk to this critically endangered species.</p>","language":"English","publisher":"PLoS","doi":"10.1371/journal.pone.0088430","usgsCitation":"Johnson, J.M., Haig, S.M., Schwarz, C.J., Glendening, J.W., Burnett, L.J., George, D., and Grantham, J., 2014, Resource selection by the California condor (Gymnogyps californianus) relative to terrestrial-based habitats and meteorological conditions: PLoS ONE, v. 9, no. 2, Article e88430; 13 p., https://doi.org/10.1371/journal.pone.0088430.","productDescription":"Article e88430; 13 p.","ipdsId":"IP-052760","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":473131,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pone.0088430","text":"Publisher Index Page"},{"id":287156,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -119.10278320312499,\n              36.39475669987386\n            ],\n            [\n              -118.95996093749999,\n              36.01356058518153\n            ],\n            [\n              -118.77319335937499,\n              35.46961797120201\n            ],\n            [\n              -118.66333007812499,\n              35.10193405724606\n            ],\n            [\n              -118.817138671875,\n              34.94899072578227\n            ],\n            [\n              -119.20166015625,\n              34.939985151560435\n            ],\n            [\n              -119.4873046875,\n              35.10193405724606\n            ],\n            [\n              -119.718017578125,\n              35.38904996691167\n            ],\n            [\n              -119.871826171875,\n              35.68407153314097\n            ],\n            [\n              -120.05859375,\n              36.00467348670187\n            ],\n            [\n              -120.311279296875,\n              36.19995805932895\n            ],\n            [\n              -120.62988281249999,\n              36.54494944148322\n            ],\n            [\n              -120.750732421875,\n              36.77409249464195\n            ],\n            [\n              -120.89355468749999,\n              36.914764288955936\n            ],\n            [\n              -121.35498046875,\n              36.923547681089296\n            ],\n            [\n              -121.46484375,\n              36.677230602346214\n            ],\n            [\n              -121.201171875,\n              36.36822190085111\n            ],\n            [\n              -120.91552734375,\n              35.9157474194997\n            ],\n            [\n              -120.58593749999999,\n              35.496456056584165\n            ],\n            [\n              -119.35546875000001,\n              34.66935854524543\n            ],\n            [\n              -118.553466796875,\n              34.42503613021332\n            ],\n            [\n              -118.27880859375001,\n              34.415973384481866\n            ],\n            [\n              -118.037109375,\n              34.551811369170494\n            ],\n            [\n              -118.311767578125,\n              34.687427949314845\n            ],\n            [\n              -118.553466796875,\n              34.867904962568716\n            ],\n            [\n              -118.46557617187499,\n              34.92197103616377\n            ],\n            [\n              -118.27880859375001,\n              35.12889434101051\n            ],\n            [\n              -118.30078125,\n              35.47856499535729\n            ],\n            [\n              -118.47656249999999,\n              36.03133177633187\n            ],\n            [\n              -118.47656249999999,\n              36.48314061639213\n            ],\n            [\n              -118.828125,\n              36.55377524336089\n            ],\n            [\n              -119.10278320312499,\n              36.39475669987386\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"9","issue":"2","noUsgsAuthors":false,"publicationDate":"2014-02-11","publicationStatus":"PW","scienceBaseUri":"53749075e4b0870f4d23cfe7","contributors":{"authors":[{"text":"Johnson, J.

We used simulations to evaluate trade-offs in the number of containers (replicates) employed versus the number of fish-per container when estimating tagging mortality. We also investigated effects of control fish survival and how among container variation in survival affects the ability to detect additive mortality. Simulations revealed that high experimental effort was required when: (1) additive treatment mortality was small, (2) control fish mortality was non-negligible, and (3) among container variability in control fish mortality exceeded 10% of the mean. We provided programming code to allow investigators to compare alternative designs for their individual scenarios and expose trade-offs among experimental design options.

Results from each method are compared and contrasted in order to provide information for future investigators to use while selecting appropriate sampling methods for their research. The continuous low-level aquatic monitoring (CLAM) sampler (C.I.Agent® Storm-Water Solutions) is a submersible, low flow-rate sampler, that continuously draws water through solid-phase extraction media. CLAM samplers were deployed at two wastewater-dominated stream field sites in conjunction with the deployment of polar organic chemical integrative samplers (POCIS) and the collection of discrete (grab) water samples. All samples were analyzed for a suite of 69 TOCs. The CLAM and POCIS samples represent time-integrated samples that accumulate the TOCs present in the water over the deployment period (19–23 h for CLAM and 29 days for POCIS); the discrete samples represent only the TOCs present in the water at the time and place of sampling. Non-metric multi-dimensional scaling and cluster analysis were used to examine patterns in both TOC detections and relative concentrations between the three sampling methods. A greater number of TOCs were detected in the CLAM samples than in corresponding discrete and POCIS samples, but TOC concentrations in the CLAM samples were significantly lower than in the discrete and (or) POCIS samples. Thirteen TOCs of varying polarity were detected by all of the three methods. TOC detections and concentrations obtained by the three sampling methods, however, are dependent on multiple factors. This study found that stream discharge, constituent loading, and compound type all affected TOC concentrations detected by each method. In addition, TOC detections and concentrations were affected by the reporting limits, bias, recovery, and performance of each method.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Science of the Total Environment","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.scitotenv.2013.12.082","usgsCitation":"Coes, A.L., Paretti, N., Foreman, W., Iverson, J.L., and Alvarez, D., 2014, Sampling trace organic compounds in water: a comparison of a continuous active sampler to continuous passive and discrete sampling methods: Science of the Total Environment, v. 473-474, p. 731-741, https://doi.org/10.1016/j.scitotenv.2013.12.082.","productDescription":"11 p.","startPage":"731","endPage":"741","ipdsId":"IP-043359","costCenters":[{"id":128,"text":"Arizona Water Science Center","active":true,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":287132,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":287131,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.scitotenv.2013.12.082"}],"volume":"473-474","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53749076e4b0870f4d23cff1","contributors":{"authors":[{"text":"Coes, Alissa L. 0000-0001-6682-5417 alcoes@usgs.gov","orcid":"https://orcid.org/0000-0001-6682-5417","contributorId":4231,"corporation":false,"usgs":true,"family":"Coes","given":"Alissa","email":"alcoes@usgs.gov","middleInitial":"L.","affiliations":[{"id":128,"text":"Arizona Water Science Center","active":true,"usgs":true}],"preferred":true,"id":487167,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Paretti, Nicholas V. nparetti@usgs.gov","contributorId":802,"corporation":false,"usgs":true,"family":"Paretti","given":"Nicholas V.","email":"nparetti@usgs.gov","affiliations":[{"id":128,"text":"Arizona Water Science Center","active":true,"usgs":true}],"preferred":false,"id":487165,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Foreman, William T. wforeman@usgs.gov","contributorId":1473,"corporation":false,"usgs":true,"family":"Foreman","given":"William T.","email":"wforeman@usgs.gov","affiliations":[{"id":452,"text":"National Water Quality Laboratory","active":true,"usgs":true}],"preferred":false,"id":487166,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Iverson, Jana L. jiverson@usgs.gov","contributorId":5564,"corporation":false,"usgs":true,"family":"Iverson","given":"Jana","email":"jiverson@usgs.gov","middleInitial":"L.","affiliations":[],"preferred":true,"id":487168,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Alvarez, David A.","contributorId":72755,"corporation":false,"usgs":true,"family":"Alvarez","given":"David A.","affiliations":[],"preferred":false,"id":487169,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Comparing covariate recorded values among simultaneous observations revealed inconsistency between observers. We showed that the variation among simple counts means the current direct count survey, even if interpreted as a proportional index of abundance, incorporates many sources of uncertainty that are not taken into account. Analysis revealed violation of model assumptions that allowed us to discount distance-based estimates as a viable estimation technique.

Ecological integrity has been defined as a measure of the composition, structure, and function of an ecosystem in relation to the system’s natural or historical range of variation, as well as perturbations caused by natural or anthropogenic agents of change. Using ecological integrity to communicate with managers requires five steps, often implemented iteratively: (1) document the scale of the project and the current conceptual understanding and reference conditions of the ecosystem, (2) select appropriate metrics representing integrity, (3) define externally verified assessment points (metric values that signify an ecological change or need for management action) for the metrics, (4) collect data and calculate metric scores, and (5) summarize the status of the ecosystem using a variety of reporting methods. While we present the steps linearly for conceptual clarity, actual implementation of this approach may require addressing the steps in a different order or revisiting steps (such as metric selection) multiple times as data are collected. Knowledge of relevant ecological thresholds is important when metrics are selected, because thresholds identify where small changes in an environmental driver produce large responses in the ecosystem. Metrics with thresholds at or just beyond the limits of a system’s range of natural variability can be excellent, since moving beyond the normal range produces a marked change in their values. Alternatively, metrics with thresholds within but near the edge of the range of natural variability can serve as harbingers of potential change. Identifying thresholds also contributes to decisions about selection of assessment points. In particular, if there is a significant resistance to perturbation in an ecosystem, with threshold behavior not occurring until well beyond the historical range of variation, this may provide a scientific basis for shifting an ecological assessment point beyond the historical range. We present two case studies using ongoing monitoring by the US National Park Service Vital Signs program that illustrate the use of an ecological integrity approach to communicate ecosystem status to resource managers. The Wetland Ecological Integrity in Rocky Mountain National Park case study uses an analytical approach that specifically incorporates threshold detection into the process of establishing assessment points. The Forest Ecological Integrity of Northeastern National Parks case study describes a method for reporting ecological integrity to resource managers and other decision makers. We believe our approach has the potential for wide applicability for natural resource management.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Application of threshold concepts in natural resource decision making","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Springer","doi":"10.1007/978-1-4899-8041-0_10","usgsCitation":"Mitchell, B.R., Tierney, G.L., Schweiger, E.W., Miller, K.M., Faber-Langendoen, D., and Grace, J.B., 2014, Getting the message across: using ecological integrity to communicate with resource managers, chap. <i>of</i> Application of threshold concepts in natural resource decision making, p. 199-230, https://doi.org/10.1007/978-1-4899-8041-0_10.","productDescription":"32 p.","startPage":"199","endPage":"230","ipdsId":"IP-028833","costCenters":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"links":[{"id":284216,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":283826,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/978-1-4899-8041-0_10"},{"id":283827,"type":{"id":15,"text":"Index Page"},"url":"https://link.springer.com/chapter/10.1007/978-1-4899-8041-0_10"}],"country":"United States","noUsgsAuthors":false,"publicationDate":"2014-02-08","publicationStatus":"PW","scienceBaseUri":"53517043e4b05569d805a231","contributors":{"authors":[{"text":"Mitchell, Brian R.","contributorId":14683,"corporation":false,"usgs":true,"family":"Mitchell","given":"Brian","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":491440,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Tierney, Geraldine L.","contributorId":26218,"corporation":false,"usgs":true,"family":"Tierney","given":"Geraldine","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":491441,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schweiger, E.
