Database of amphibian occurrence in the Amazon

Primary biodiversity data are essential for understanding spatial and temporal patterns of biodiversity. Here we provide an extensive database obtained from four distinct sources: online platforms, peer-reviewed publications, non-peer-reviewed academic publications (grey literature) and personal collections deposited in specialized scientific collections. Thus, the database consists of 213,072 georeferenced occurrence records for 951 amphibian species distributed in 24,319 sampling points in the Amazon. This robust database contributed to the understanding of amphibian sampling distribution patterns in the Amazon, highlighting sampling gaps and biases in large-scale amphibian sampling patterns, supporting conservation actions and will be freely accessible for future spatial and temporal analyses that bring understanding of ecological patterns and functions of this important taxonomic group that are amphibians.
