Occurrence of the amphibians in the Volga, Don River basins and adjacent territories (Russia): research in 1996-2020

Knowledge about the distribution of living organisms on Earth is very important for many areas of biological science and understanding of the surrounding world. However, much of the existing distributional data are scattered throughout a multitude of sources, such as taxonomic publications, checklists and natural history collections. And often bring them together is difficult. A very successful attempt to solve this problem is the GBIF project, which allows a huge number of researchers to publish data in one place in a single standard. Our dataset represents a significant addition to the occurrences of amphibians in the Volga, Don riverine basins and adjacent territories.The dataset contains up-to-date information on amphibian occurrences in the Volga river basin and adjacent territories, located most part on the Russian plain of European Russia. Dataset is based on its own studies that were conducted in the years 1996-2020. The dataset consists of 4,627 incident records, all linked to geographical coordinates. A total of 13 amphibian species belonging to 9 genera and 6 families have been registered within the studied territory, although the distribution of amphibian species in this region of Russia has not yet been fully studied. This is especially relevant with the spread of cryptic species that can only be identified using molecular genetic research methods.The main purpose of publishing a database is to make our data available in the global biodiversity system to a wide range of users. The data can be used by researchers, as well as to help the authorities to manage their territory more efficiently.All occurrences are published in GBIF for the first time. Most of the data is stored in field diaries and we would like to make it available to everyone by adding it in the global biodiversity database (GBIF).
