Number of globally threatened animals, by terrestrial ecoregion. We compiled a vertebrate species list for each ecoregion from WWF’s WildFinder database (WWF 2006). This list was then compared against the IUCN Red List of Threatened Species (2008) to determine the number of species per ecoregion that are threatened. Threatened species are those listed by IUCN Red List as Vulnerable, Endangered, or Critically Endangered (www.redlist.org). These data were derived by The Nature Conservancy, and were displayed in a map published in The Atlas of Global Conservation (Hoekstra et al., University of California Press, 2010). More information at http://nature.org/atlas. Data derived from: World Wildlife Fund (WWF). 2006....

The Long Term Resource Monitoring Programs (LTRMP) annual fish monitoring began on the Upper Mississippi and Illinois Rivers in 1989. During the first two years samples were collected at a series of fixed sampling sites, then in 1993 a stratified random sampling approach was added to the collection effort. This approach utilizes a computer routine that randomly selects sampling sites from a pool of potential sites that have been categorized by strata (e.g., aquatic habitat type, distance to shore, connectivity to main channel). The results from these collections are stored in an Oracle database at the Upper Midwest Environmental Science Center (UMESC). UMESC provides free access to the data through the Centers Web...

Calfifornia condor occurrence data, downloaded from USGS BISON. The USGS Biodiversity Information Serving Our Nation (BISON) project is an online mapping information system consisting of a large collection of species occurrence datasets (e.g., plants and animals) found in the United States, with relevant geospatial layers. Species occurrences are records of organisms at a particular time and location that are often collected as part of biological field studies and taxonomic collections. These data serve as a foundation for biodiversity and conservation research. BISON supports several data interchange formats to enable developers to write custom applications (http://bison.usgs.ornl.gov/services.html). The BISON...

When a species is proposed for listing as endangered or threatened under the Endangered Species Act, the U.S. Fish and Wildlife Service must consider whether there are areas of habitat believed to be essential the species’ conservation. Those areas may be proposed for designation as “critical habitat.” Critical habitat is a term defined and used in the Act. It is a specific geographic area(s) that contains features essential for the conservation of a threatened or endangered species and that may require special management and protection. Critical habitat may include an area that is not currently occupied by the species but that will be needed for its recovery. An area is designated as “critical habitat” after the...

Climate change vulnerability assessments are commonly used to identify species or populations at risk from global climate change, but few translate impact assessments to climate change adaptation actions. Furthermore, most climate change adaptation efforts emphasize where to implement management actions, whereas timing remains largely overlooked. The rate of modern climate change introduces urgency in evaluating whether delaying conservation actions compromises their efficacy for reaching important conservation targets. We evaluated the importance of multiple climate change adaptation strategies including timing of actions on preventing extinctions for a threatened climate-sensitive species, the Eastern Massasauga...

Abstract (from http://www.nature.com/nclimate/journal/vaop/ncurrent/full/nclimate2252.html): Climate change will decrease worldwide biodiversity through a number of potential pathways1, including invasive hybridization2 (cross-breeding between invasive and native species). How climate warming influences the spread of hybridization and loss of native genomes poses difficult ecological and evolutionary questions with little empirical information to guide conservation management decisions3. Here we combine long-term genetic monitoring data with high-resolution climate and stream temperature predictions to evaluate how recent climate warming has influenced the spatio-temporal spread of human-mediated hybridization between...

We analyzed variation in canopy closure around 47 Mexican spotted owl (Strix occidentalis lucida) nest sires and 47 random forest sites on the Coconino National Forest in northcentral Arizona. We mapped distinct habitat polygons on 1:15,840 color aerial photographs, assigned each polygon to one of 4 canopy-closure classes (70%), and measured the area in each canopy class within 5 concentric analysis zones with radii of 0.1, 0.4, 0.8, 1.2, and 1.6 km (delineating rings of about 4, 47, 150, 252, and 352 ha). Landscape composition differed between spotted owl nest and random sites (P 70% canopy-closure class and less area in the 70% canopy predominated Nesting spotted owls selected areas with denser canopy than randomly...

Number of globally threatened marine mammal species, by marine ecoregion. Using the online IUCN resource, the threatened species for each ecoregion were filtered for marine species only. Threatened species refer to those listed by IUCN Red List as Vulnerable, Endangered, or Critically Endangered (www.redlist.org). We downloaded the digital GIS data and summarized it by marine ecoregion to result in the number of threatened species per marine ecoregion. These data were derived by The Nature Conservancy, and were displayed in a map published in The Atlas of Global Conservation (Hoekstra et al., University of California Press, 2010).

We developed an expert opinion questionnaire to gather information regarding expert opinion regarding the importance of climate variables in determining a species geographic range (Brandt et al. 2017). The data on the Survey_Results tab represent the raw survey questions and responses. Each column in the spreadsheet (except the first four columns, described below) represents a survey question, which is written in the first cell of that column. Each survey response for that question is listed below. Some questions have multi-part answers, and are listed in multiple columns, and appended with letters (e.g., Q8A, Q8B, Q8C, etc.). The first four columns of the spreadhseet represent unique information for that survey...
Small-bodied, riverine minnows that historically characterized fish assemblages of Great Plains rivers in North America have declined because of river fragmentation, dewatering, river channel degradation, river salinization and nonnative species introductions. The Pecos bluntnose shiner Notropis simus pecosensis, a member of this guild, persists in one segment of the Pecos River, New Mexico, USA. We characterized habitat associations for the species at two spatial scales. In general, N. s. pecosensis associated with fluvial habitats, but velocity association depended on body size, with larger individuals using swifter habitats. All N. s. pecosensis associated with relatively low depths (3–51 cm), which were most...

This map shows areas designated (or proposed) as critical habitat for one or more listed (or proposed for listing) populations of aquatic species in Washington. Note that in this map each Evolutionarily Significant Unit and each Distinct Population Segment is considered as one population. Critical habitat constitutes areas considered essential for the conservation of a listed species. These areas provide notice to the public and land managers of the importance of the areas to the conservation of this species. Special protections and/or restrictions are possible in areas where Federal funding, permits, licenses, authorizations, or actions occur or are required. Freshwater/riparian-related species or populations...

Ten polymorphic microsatellite loci (containing tri and tetra-nucleotide repeats) were developed for the Lahontan cutthroat trout (Oncorhynchus clarki henshawi), a subspecies of cutthroat trout listed as threatened under the United States Endangered Species Act. Polymorphism was assessed for 445 individuals from 12 populations representing eight watersheds spread throughout the three Distinct Population Segments defined for this subspecies. All loci were polymorphic (X? = 19, range 7?26 alleles). All loci were in Hardy?Weinberg equilibrium (HWE) except for one locus (OCH 9) in a single population (P < 0.00014 after Bonferroni correction for multiple tests). Published in Molecular Ecology Notes, volume 4, issue 4,...

We developed a modelling spatial domain, or mask, to delimit the modeling extent for each species (n=15 species), as a part of a larger project to compare climate envelope models outputs that were generated using two types of predictor variables: expert opinion and statistical method (Brandt et al. 2017). The species masks, or model domains, were defined separately for each species using a variation of the “target-group” approach (Phillips et al. 2009), where the domain was determine using convex polygons including occurrence data for at least three phylogenetically related and similar species (Watling et al. 2012). This dataset is separated into 15 zipped GeoTIFF rasters, each with its own metadata documentation....
