FY2017There is an increasing concern and need for the conservation of springsnails and other endemic mollusks and for conservation of the unique spring and springbrook habitats on which they depend (Hershler et al 2014; Abele 2011). Nationwide, several of these species have been listed as endangered or threatened under provisions of the ESA; others are candidates for federal listing or are undergoing review by USFWS for possible future listing actions. These species can be particularly susceptible to localized threats and specific knowledge necessary for effective site-based conservation is often limited or lacking.Springsnail are particularly susceptible to extinction because the entire population of any single...

THIS IS A HISTORICAL RECORD. As of December 17, 2021, the BISON application will no longer be available online and has been replaced by https://www.gbif.us. The BISON APIs are still available at https://bison.usgs.gov/#api and the Integrated Publishing Toolkit is still available at https://bison.usgs.gov/ipt. The USGS Biodiversity Information Serving Our Nation (BISON) project is an online all-species mapping information system consisting of a large collection of species occurrence datasets (e.g., plants and animals) found in the United States, U.S. Territories, U.S. marine Exclusive Economic Zones (EEZ), and Canada, with relevant geospatial layers. Species occurrences are records of organisms at a particular...

Monitoring demographic response over time is valuable for understanding population dynamics of endangered species. We quantified the variation in survival patterns for three small isolated island populations of endangered Laysan ducks (Anas laysanensis; also called Laysan teal) in the Hawaiian Archipelago using data from individually marked birds. Using the median or maximum resight intervals of individually marked birds and carcass recovery dates the survival of ducks at Laysan Island, Midway Atoll, and Kure Atoll was estimated. This dataset includes demographic information for each bird released, mortality information, and data used to calculate population survival.

The CA Academy of Science and Point Blue Conservation Science conducted a systematic analysis of uncertainty in modeling the future distributions of ~50 California endemic plant species and ~50 California land birds, explicitly partitioning among 5 alternative sources of variation and testing for their respective contributions to overall variation among modeled outcomes. They mapped the uncertainty from identified sources, which can guide decisions about monitoring, restoration, acquisition, infrastructure, etc., in relation to climate change.
