Through nonmetric multidimensional scaling, we documented a 1970s community largely dominated by alewife, and then a shift to a community dominated by several native species during the 1980s through 1990s, when alewife remained at relatively low levels. We argue that the recovery of burbot (</span><i>Lota lota</i><span>), deepwater sculpin (</span><i>Myoxocephalus thompsonii</i><span>), and yellow perch (</span><i>Perca flavescens</i><span>) was partially or fully aided by the alewife reduction. We argue that changes in phosphorus or salmonines were not directly related to abundance increases of native species. An additional community shift occurred during 1999&ndash;2004, which coincided with a reduction in species richness and total fish biomass in our trawl.

We developed a maximum likelihood-based analysis to estimate spatial and temporal trends in age/sex-specific survival rates for the threatened southern sea otter (Enhydra lutris nereis), using annual population censuses and the age structure of salvaged carcass collections. We evaluated a wide range of possible spatial and temporal effects and used model averaging to incorporate model uncertainty into the resulting estimates of key vital rates and their variances. We compared these results to current demographic parameters estimated in a telemetry-based study conducted between 2001 and 2004. These results show that survival has decreased substantially from the early 1990s to the present and is generally lowest in the north-central portion of the population's range. The greatest temporal decrease in survival was for adult females, and variation in the survival of this age/sex class is primarily responsible for regulating population growth and driving population trends. Our results can be used to focus future research on southern sea otters by highlighting the life history stages and mortality factors most relevant to conservation. More broadly, we have illustrated how the powerful and relatively straightforward tools of information-theoretic-based model fitting can be used to sort through and parameterize quite complex demographic modeling frameworks. ?? 2006 by the Ecological Society of America.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Applications","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1890/1051-0761(2006)016[2293:IDDARC]2.0.CO;2","issn":"10510761","usgsCitation":"Tinker, M.T., Doak, D.F., Estes, J.A., Hatfield, B.B., Staedler, M., and Gross, A., 2006, Incorporating diverse data and realistic complexity into demographic estimation procedures for sea otters: Ecological Applications, v. 16, no. 6, p. 2293-2312, https://doi.org/10.1890/1051-0761(2006)016[2293:IDDARC]2.0.CO;2.","productDescription":"20 p.","startPage":"2293","endPage":"2312","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":236683,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209925,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/1051-0761(2006)016[2293:IDDARC]2.0.CO;2"}],"volume":"16","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a39e9e4b0c8380cd61a9e","contributors":{"authors":[{"text":"Tinker, M.

We conducted 21- and 30-d experiments with young fathead minnows (Pimephales promelas) and rainbow trout (Oncorhynchus mykiss), respectively, to determine whether a diet consisting solely of L. variegatus would support normal growth and to compare performance with standard diets (Artemia nauplii, frozen brine shrimp, or trout chow). All diets were readily accepted, and fish survived and grew well. Food conversion in both fathead minnows and rainbow trout was as high as or higher for the oligochaete diet compared with others, although this comparison is influenced by differences in ration, ingestion rate, or both. The oligochaete diet had gross nutritional analysis similar to the other diets, and meets fish nutrition guidelines for protein and essential amino acids. Methodologies and practical considerations for successfully using oligochaetes as an experimental diet are discussed. Considering their ready acceptance by fish, their apparent nutritional sufficiency, the ease of culturing large numbers, and the ease with which they can be loaded with exogenous chemicals, we believe that L. variegatus represents an excellent choice of exposure vector for exposing fish to toxicants via the diet. ?? 2006 SETAC.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Toxicology and Chemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1897/06-138.1","issn":"07307268","usgsCitation":"Mount, D., Highland, T., Mattson, V., Dawson, T., Lott, K., and Ingersoll, C., 2006, Use of the oligochaete, Lumbriculus variegatus, as a prey organism for toxicant exposure of fish through the diet: Environmental Toxicology and Chemistry, v. 25, no. 10, p. 2760-2767, https://doi.org/10.1897/06-138.1.","startPage":"2760","endPage":"2767","numberOfPages":"8","costCenters":[],"links":[{"id":209991,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1897/06-138.1"},{"id":236775,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"10","noUsgsAuthors":false,"publicationDate":"2006-10-01","publicationStatus":"PW","scienceBaseUri":"505bbf9ee4b08c986b329c80","contributors":{"authors":[{"text":"Mount, D.R.","contributorId":13774,"corporation":false,"usgs":true,"family":"Mount","given":"D.R.","email":"","affiliations":[],"preferred":false,"id":418712,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Highland, T.L.","contributorId":52387,"corporation":false,"usgs":true,"family":"Highland","given":"T.L.","email":"","affiliations":[],"preferred":false,"id":418714,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mattson, V.R.","contributorId":82909,"corporation":false,"usgs":true,"family":"Mattson","given":"V.R.","email":"","affiliations":[],"preferred":false,"id":418716,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dawson, T.D.","contributorId":42738,"corporation":false,"usgs":true,"family":"Dawson","given":"T.D.","email":"","affiliations":[],"preferred":false,"id":418713,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Lott, K.G.","contributorId":91674,"corporation":false,"usgs":true,"family":"Lott","given":"K.G.","email":"","affiliations":[],"preferred":false,"id":418717,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Ingersoll, C.G. 0000-0003-4531-5949","orcid":"https://orcid.org/0000-0003-4531-5949","contributorId":56338,"corporation":false,"usgs":true,"family":"Ingersoll","given":"C.G.","affiliations":[],"preferred":false,"id":418715,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

In the past two centuries, more than 79% of the historic tidal wetlands in this estuary have been lost. Resource management agencies have acquired more than 10&nbsp;000&nbsp;ha of commercial salt ponds with plans to undertake one of the largest wetland restoration projects in North America. However, these plans have created debate about the ecological importance of salt ponds for migratory bird communities in western North America. Salt ponds are unique mesohaline (5–18&nbsp;g&nbsp;l</span><sup>−1</sup><span>) to hyperhaline (&gt; 40&nbsp;g&nbsp;l</span><sup>−1</sup><span>) wetlands, but little is known of their ecological structure or value. Thus, we studied decommissioned salt ponds in the North Bay of the San Francisco Bay estuary from January 1999 through November 2001. We measured water quality parameters (salinity, DO, pH, temperature), nutrient concentrations, primary productivity, zooplankton, macroinvertebrates, fish, and birds across a range of salinities from 24 to 264&nbsp;g&nbsp;l</span><sup>−1</sup><span>. Our studies documented how unique limnological characteristics of salt ponds were related to nutrient levels, primary productivity rates, invertebrate biomass and taxa richness, prey fish, and avian predator numbers. Salt ponds were shown to have unique trophic and physical attributes that supported large numbers of migratory birds. Therefore, managers should carefully weigh the benefits of increasing habitat for native tidal marsh species with the costs of losing these unique hypersaline systems.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s10750-006-0061-z","usgsCitation":"Takekawa, J.Y., Miles, A., Schoellhamer, D., Athearn, N., Saiki, M.K., Duffy, W., Kleinschmidt, S., Shellenbarger, G., and Jannusch, C., 2006, Trophic structure and avian communities across a salinity gradient in evaporation ponds of the San Francisco Bay estuary: Hydrobiologia, v. 567, no. 1, p. 307-327, https://doi.org/10.1007/s10750-006-0061-z.","productDescription":"21 p.","startPage":"307","endPage":"327","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true},{"id":552,"text":"San Francisco Bay-Delta","active":false,"usgs":true},{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true},{"id":5079,"text":"Pacific Regional Director's Office","active":true,"usgs":true}],"links":[{"id":321188,"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              -122.34718322753905,\n              38.21363682695095\n            ],\n            [\n              -122.27920532226562,\n              38.205274034117814\n            ],\n            [\n              -122.27783203125,\n              38.15426719087882\n            ],\n            [\n              -122.2623825073242,\n              38.13860713787158\n            ],\n            [\n              -122.28057861328124,\n              38.11970259728823\n            ],\n            [\n              -122.39730834960938,\n              38.14940753418616\n            ],\n            [\n              -122.35851287841797,\n              38.21417632897687\n            ],\n            [\n              -122.34718322753905,\n              38.21363682695095\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"567","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5735a95ce4b0dae0d5df518b","contributors":{"authors":[{"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":629232,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Miles, A.K. 0000-0002-3108-808X","orcid":"https://orcid.org/0000-0002-3108-808X","contributorId":85902,"corporation":false,"usgs":true,"family":"Miles","given":"A.K.","affiliations":[],"preferred":false,"id":629233,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schoellhamer, D.

We quantified the percentage cover of bare ground, percentage cover of shrubs (Chrysothamnus visadiflorus), linear distance to nearest shrub, arthropod biomass, and grasshopper density for 102 plots of 1,963 m2, 51 of which were occupied by plovers and 51 of which were selected randomly within previously-classified potential habitat. We modeled the probability of habitat use by plovers based on these measurements. We further subdivided the occupied plots to model probability of habitat use by adults with broods as compared with use by pre-nesting and post-nesting adults. Percentage of bare ground and probability of habitat use for adults with broods were related inversely, but not so for adults without broods. Grasshopper density was positively related to probability of habitat use by adults without broods, whereas proximity to nearest shrub was negatively related. We propose that habitat use by plovers in South Park is influenced by the amount of available shrub-grassland edge habitat and the availability of forage.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Southwestern Naturalist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1894/0038-4909(2006)51[197:RBSAFI]2.0.CO;2","issn":"00384909","usgsCitation":"Schneider, S., Wunder, M., and Knopf, F., 2006, Relationship between shrubs and foods in mountain plover habitat in Park County, Colorado: Southwestern Naturalist, v. 51, no. 2, p. 197-202, https://doi.org/10.1894/0038-4909(2006)51[197:RBSAFI]2.0.CO;2.","startPage":"197","endPage":"202","numberOfPages":"6","costCenters":[],"links":[{"id":210271,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1894/0038-4909(2006)51[197:RBSAFI]2.0.CO;2"},{"id":237140,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"51","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50e4a75ee4b0e8fec6cdc41d","contributors":{"authors":[{"text":"Schneider, S.C.","contributorId":92126,"corporation":false,"usgs":true,"family":"Schneider","given":"S.C.","email":"","affiliations":[],"preferred":false,"id":417753,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wunder, Michael B.","contributorId":65406,"corporation":false,"usgs":false,"family":"Wunder","given":"Michael B.","affiliations":[{"id":6674,"text":"Department of Integrative Biology, University of Colorado Denver","active":true,"usgs":false}],"preferred":false,"id":417752,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Knopf, F.L.","contributorId":26998,"corporation":false,"usgs":true,"family":"Knopf","given":"F.L.","email":"","affiliations":[],"preferred":false,"id":417751,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Arsenic contamination is also a major problem in ground and surface waters. A feasibility study was conducted to determine if neutron-activation analysis is a practical method of measuring in situ arsenic levels. The response of hypothetical well-logging tools to arsenic was simulated using a readily available Monte Carlo simulation code (MCNP). Simulations were made for probes with both hyperpure germanium (HPGe) and bismuth germanate (BGO) detectors using accelerator and isotopic neutron sources. Both sources produce similar results; however, the BGO detector is much more susceptible to spectral interference than the HPGe detector. Spectral interference from copper can preclude low-level arsenic measurements when using the BGO detector. Results show that a borehole probe could be built that would measure arsenic concentrations of 100 ppm by weight to an uncertainty of 50 ppm in about 15 min. ?? 2006 Elsevier Ltd.

Counting auklets on surface plots is the primary method used to track changes in numbers of these crevice-nesters, but counts can be highly variable and may not be representative of the number of nesting individuals. We compared average maximum counts of Least Auklets on surface plots with density estimates based on mark–resight data at a colony on St. Lawrence Island, Alaska, during 2001–2004. Estimates of breeding auklet abundance from mark–resight averaged 8 times greater than those from maximum surface counts. Our results also indicate that average maximum surface counts are poor indicators of breeding auklet abundance and do not vary consistently with auklet nesting density across the breeding colony. Estimates of Least Auklet abundance from mark–resight were sufficiently precise to meet management goals for tracking changes in seabird populations. We recommend establishing multiple permanent banding plots for mark–resight studies on colonies selected for intensive long-term monitoring. Mark–resight is more likely to detect biologically significant changes in size of auklet breeding colonies than traditional surface count techniques.</span></p>","language":"English","publisher":"NRC Research Press","doi":"10.1139/Z06-061","issn":"00084301","usgsCitation":"Sheffield, L., Gall, A.E., Roby, D., Irons, D., and Dugger, K., 2006, Monitoring planktivorous seabird populations: Validating surface counts of crevice-nesting auklets using mark-resight techniques: Canadian Journal of Zoology, v. 84, no. 6, p. 846-854, https://doi.org/10.1139/Z06-061.","startPage":"846","endPage":"854","numberOfPages":"9","costCenters":[],"links":[{"id":237103,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":210240,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1139/Z06-061"}],"volume":"84","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5dd3e4b0c8380cd70608","contributors":{"authors":[{"text":"Sheffield, L.M.","contributorId":40000,"corporation":false,"usgs":true,"family":"Sheffield","given":"L.M.","email":"","affiliations":[],"preferred":false,"id":417741,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gall, Adrian E.","contributorId":54396,"corporation":false,"usgs":false,"family":"Gall","given":"Adrian","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":417743,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Roby, D.D. 0000-0001-9844-0992","orcid":"https://orcid.org/0000-0001-9844-0992","contributorId":70944,"corporation":false,"usgs":true,"family":"Roby","given":"D.D.","affiliations":[],"preferred":false,"id":417744,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Irons, D.B.","contributorId":52922,"corporation":false,"usgs":true,"family":"Irons","given":"D.B.","email":"","affiliations":[],"preferred":false,"id":417742,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Dugger, K.M.","contributorId":25729,"corporation":false,"usgs":true,"family":"Dugger","given":"K.M.","email":"","affiliations":[],"preferred":false,"id":417740,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Factors such as disturbance severity, resource availability, and propagule pressure may influence where non-native species establish in burned areas. In addition, pre- and post-fire management activities may influence the likelihood of non-native species establishment. In the present study we examine the establishment of non-native species after wildfires in relation to native species richness, fire severity, dominant native plant cover, resource availability, and pre- and post-fire management actions (fuel treatments and post-fire rehabilitation treatments). We used an information-theoretic approach to compare alternative hypotheses. We analysed post-fire effects at multiple scales at three wildfires in Colorado and New Mexico. For large and small spatial scales at all fires, fire severity was the most consistent predictor of non-native species cover. Non-native species cover was also correlated with high native species richness, low native dominant species cover, and high seeded grass cover. There was a positive, but non-significant, association of non-native species with fuel-treated areas at one wildfire.

Some shorebirds renowned for their extraordinary long-distance migrations, notably American Golden-Plover (<i>Pluvialis dominica</i>), Red Knot (<i>Calidris canutus rufa</i>), and White-rumped Sandpiper (<i>C. fuscicollis</i>), travel as many as 15,000 km between southern South American wintering grounds and Canadian Arctic breeding areas. Migration strategies of shorebirds vary in many aspects. There are remarkable accounts of shorebirds, such as northbound Red Knots, that stage in a few key sites for 2–3 weeks and lay on extensive body stores, then fly nonstop for distances of ≤2,500 km (Harrington 2001, Piersma et al. 2005). Less well known are the examples of populations that refuel only briefly at stopover sites, disperse broadly on the landscape, and fly shorter distances between sites (Skagen 1997, Haig et al. 1998, Warnock et al. 1998). This latter pattern applies to many long-distance migrant shorebirds that cross the interior plains of North America during spring and fall migrations. For them, interior wetland complexes provide critical refueling resources along the direct routes between summering and wintering grounds (Skagen et al. 1999). In this issue of The Auk, Krapu et al. (2006) describe patterns and implications of fat deposition by Semipalmated Sandpipers (<i>C. pusilla</i>), White-rumped Sandpipers, and Baird's Sandpipers (<i>C. bairdii</i>) refueling during northward migration across the prairies of mid-continental North America.</p>","language":"English","publisher":"American Ornithological Society","doi":"10.1642/0004-8038(2006)123[313:MSATCO]2.0.CO;2","usgsCitation":"Skagen, S.K., 2006, Migration stopovers and the conservation of arctic-breeding Calidrine sandpipers: The Auk, v. 123, no. 2, p. 313-322, https://doi.org/10.1642/0004-8038(2006)123[313:MSATCO]2.0.CO;2.","productDescription":"10 p.","startPage":"313","endPage":"322","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":477569,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1642/0004-8038(2006)123[313:msatco]2.0.co;2","text":"Publisher Index Page"},{"id":133379,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"123","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a60e4b07f02db635556","contributors":{"authors":[{"text":"Skagen, Susan K. 0000-0002-6744-1244 skagens@usgs.gov","orcid":"https://orcid.org/0000-0002-6744-1244","contributorId":2009,"corporation":false,"usgs":true,"family":"Skagen","given":"Susan","email":"skagens@usgs.gov","middleInitial":"K.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":false,"id":322418,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

We hypothesized that the species density of native and non-indigenous taxa would generally decrease in northern latitudes and higher elevations following declines in potential evapotranspiration, mean temperature, and precipitation. County data on plants (</span><i class=\"EmphasisTypeItalic \">n</i><span> = 3004 counties) and birds (</span><i class=\"EmphasisTypeItalic \">n</i><span>=3074 counties), and drainage (6 HUC) data on fishes (</span><i class=\"EmphasisTypeItalic \">n</i><span> = 328 drainages) showed that the densities of native and non-indigenous species were strongly positively correlated for plant species (</span><i class=\"EmphasisTypeItalic \">r</i><span> = 0.86, </span><i class=\"EmphasisTypeItalic \">P</i><span> &lt; 0.0001), bird species (</span><i class=\"EmphasisTypeItalic \">r</i><span> = 0.93, </span><i class=\"EmphasisTypeItalic \">P</i><span>&lt;0.0001), and fish species (</span><i class=\"EmphasisTypeItalic \">r</i><span> = 0.41, </span><i class=\"EmphasisTypeItalic \">P</i><span>&lt;0.0001). Multiple regression models showed that the densities of native plant and bird species could be strongly predicted (adj. </span><i class=\"EmphasisTypeItalic \">R</i><sup>2</sup><span> = 0.66 in both models) at county levels, but fish species densities were less predictable at drainage levels (adj. </span><i class=\"EmphasisTypeItalic \">R</i><sup>2</sup><span> = 0.31,</span><i class=\"EmphasisTypeItalic \">P</i><span>&lt;0.0001). Similarly, non-indigenous plant and bird species densities were strongly predictable (adj. </span><i class=\"EmphasisTypeItalic \">R</i><sup>2</sup><span> = 0.84 and 0.91 respectively), but non-indigenous fish species density was less predictable (adj. </span><i class=\"EmphasisTypeItalic \">R</i><sup>2</sup><span> = 0.38). County level hotspots of native and non-indigenous plants, birds, and fishes were located in low elevation areas close to the coast with high precipitation and productivity (vegetation carbon). We show that (1) native species richness can be moderately well predicted with abiotic factors; (2) human populations have tended to settle in areas rich in native species; and (3) the richness and density of non-indigenous plant, bird, and fish species can be accurately predicted from biotic and abiotic factors largely because they are positively correlated to native species densities. We conclude that while humans facilitate the initial establishment, invasions of non-indigenous species, the spread and subsequent distributions of non-indigenous species may be controlled largely by environmental factors.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s10530-005-6422-0","usgsCitation":"Stohlgren, T.J., Barnett, D., Flather, C., Fuller, P.L., Peterjohn, B.G., Kartesz, J., and Master, L.L., 2006, Species richness and patterns of invasion in plants, birds, and fishes in the United States: Biological Invasions, v. 8, no. 3, p. 427-447, https://doi.org/10.1007/s10530-005-6422-0.","productDescription":"21 p.","startPage":"427","endPage":"447","numberOfPages":"21","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":133381,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"8","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a60e4b07f02db634fce","contributors":{"authors":[{"text":"Stohlgren, Thomas J. 0000-0001-9696-4450 stohlgrent@usgs.gov","orcid":"https://orcid.org/0000-0001-9696-4450","contributorId":2902,"corporation":false,"usgs":true,"family":"Stohlgren","given":"Thomas","email":"stohlgrent@usgs.gov","middleInitial":"J.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":322421,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Barnett, David","contributorId":174944,"corporation":false,"usgs":false,"family":"Barnett","given":"David","affiliations":[],"preferred":false,"id":322424,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Flather, Curtis","contributorId":104779,"corporation":false,"usgs":true,"family":"Flather","given":"Curtis","affiliations":[],"preferred":false,"id":322427,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Fuller, Pamela L. 0000-0002-9389-9144 pfuller@usgs.gov","orcid":"https://orcid.org/0000-0002-9389-9144","contributorId":3217,"corporation":false,"usgs":true,"family":"Fuller","given":"Pamela","email":"pfuller@usgs.gov","middleInitial":"L.","affiliations":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"preferred":false,"id":322422,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Peterjohn, Bruce G. bpeterjohn@usgs.gov","contributorId":4493,"corporation":false,"usgs":true,"family":"Peterjohn","given":"Bruce","email":"bpeterjohn@usgs.gov","middleInitial":"G.","affiliations":[],"preferred":true,"id":322425,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Kartesz, John","contributorId":11132,"corporation":false,"usgs":true,"family":"Kartesz","given":"John","affiliations":[],"preferred":false,"id":322423,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Master, Lawrence L.","contributorId":174945,"corporation":false,"usgs":false,"family":"Master","given":"Lawrence","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":322426,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}
