AMPHIBIAWEB

AmphibiaWeb and its Data Sources

Species Accounts:

We aim to have a web page for every species of amphibian in the world. A species account provides the basic details on its biology and conservation status and threats. These are researched from the primary scientific literature, written by experts and university students alike from herpetology classes around the US or from the UC Berkeley AmphibiaWeb apprenticeship. In addition, we compile and provide links to relevant resources and to our partners' databases as well.

For some accounts, we have agreements with publishers to display content directly from their books, allowing us to offer in-depth perspectives or alternative languages. Current book contributors include:

  • Amphibian Declines: The Conservation Status of United States Species, edited by Michael Lannoo, UC Press
  • Les Urodèles du Monde, 1st and 2nd editions, by Jean Raffaëlli
  • Guia de Sapos da Reserva Adolpho Ducke, Amazonia Central by Lima, AP, WE Magnusson, M Menin, LK Erdtmann, DJ Rodrigues, C Keller, W Hödl 2005, INPA
  • Crocodile Newts: The Primitive Salamandridae of Asia (Genera Echinotriton and Tylototriton) by Axel Hernandez, 2016, Edition Chimaira
  • We also reciprocate or share our species accounts with:

  • The IUCN Redlist of Threatened Species
  • Encyclopedia of Life
  • Above all, we have all the students and experts to thank who have given their time and expertise.

    What is a species account?

    A species account is a brief review that summarizes basic information about a species including life history traits, distribution, a general description, population trends and threats, etc. The purpose of a species account is to bring different sources of information together summarizing what is and is not known. Accounts are not intended to be exhaustive, but should be seen as a point of departure for those who wish to find more in-depth information. For most of the amphibians of the world, there is little to nothing known. However, we hope to have a web page and a species account for these amphibians because this will highlight our lack of knowledge and may help guide future studies.

    Taxonomy:

    Taxonomy is an evolving enterprise for AmphibiaWeb. We aim to keep up to date and track new species as they are formally described. The taxonomy in our database is available with crosswalks to IUCN and Amphibian Species of the World for downloading at any time.

    Mapping data:

    1. We display voucher specimen sites on the dynamic BerkeleyMapper widget for each species in cooperation with our partner VertNet, which supplies us with fresh data on a regular, quarterly basis. VertNet serves over 17 M records of species from over 200 collections around the world.
    2. For newly discovered species, holotype localities are often the only known sites of their distribution. We extract the locality data directly from the original description and enter those in our database to display on maps.
    3. When possible we show range map for each species with the sites, which come from two sources: the IUCN Redlist and from our own research, often created by our undergraduate apprentices. We post the AmphibiaWeb ranges on our Github site.
    4. In Spring 2017, we started including the Map of Life species range widget on each species page which displays spatial data from the Map of Life Project. The data that they display is currently independent from AmphibiaWeb's but we hope to coordinate and share our datasets in the future.

    Media:

    AmphibiaWeb stores or embeds video, sound and images from a variety of sources, which include:

  • Sound files from FonoZoo (Museo Nacional de Ciencias Naturales (CSIC), Madrid, Spain) and Western Soundscape Archive (University of Utah)
  • Video and sound recordings directly from contributors, some are hosted on the AmphibiaWeb YouTube channel.
  • Species Photos come from CalPhotos, which serves as AmphibiaWeb's photo repository site for our many contributors around the world.
  • AmphibiaWeb updates its pages regularly, but assumes no responsibility for the accuracy, currency, or completeness of content. Please report any errors or inaccuracies.
