Географический охват

United States of America (USA).

Таксономический охват

The North American Amphibian Atlas follows the Society for the Study of Amphibians and Reptiles (SSAR) publications. The Hawaiian Islands are not covered by the SSAR and we use the Integrated Taxonomic Information System (ITIS - http://www.itis.gov) for determining valid taxonomy and nomenclature for amphibians introduced to those islands. Most maps are species level information. We provide distribution maps for the following subspecies: Ambystoma macrodactylum croceum (Santa Cruz long-toed salamander) Ambystoma tigrium stebbinsi (Sonoran tiger salamander) Batrachoseps major aridus (desert slender salamander) Batrachoseps major major (garden slender salamander) Rana aurora aurora (northern red-legged frog) Rana aurora draytonii (California red-legged frog) In addition, we provide species complex maps for the following: Bufo fowleri and Bufo woodhousii complex (Woodhouse’s and Fowler’s toad complex) Hyla chrysoscelis and Hyla versicolor complex (gray treefrog species complex) Pseudacris triseriata, P. maculata, and P. feriarum complex (chorus frog complex)

Данные проекта

Origin of Dataset: This project began in 1999, when distribution maps and associated spreadsheets were first assembled for all amphibian species known to occur in the United States to accompany the book, "Amphibian Declines: the Status and Conservation of United States Species" (Lannoo, 2005; see Acknowledgements). In 2001 the dataset was purchased by USGS Patuxent Wildlife Research Center and used to develop the former website (Amphibian Research and Monitoring Initiative's National Atlas for Amphibian Distributions, www.pwrc.usgs.gov/armiatlas). Website maps were last updated on September 2004. From 2002-2005 the USGS dataset was updated by Priya Nanjappa Mitchell. The maps in the Amphibian Declines book were based on the updated dataset circa January 2005. In 2006-2007 the dataset was converted to a relational database. After conversion the two formats were compared for quality assurance. Then maps from the book were compared to maps generated from the new relational database. Any differences were investigated to ensure the maps were properly converted and differences were intended updates. Additional new information was obtained from various sources, see Version Information section for more details. This dataset and associated maps will be periodically updated. Updates will be assigned a version number and the version information page will document what changes have occurred.
