Maxent software for modeling species niches and distributions

The Maxent software is based on the maximum-entropy approach for modeling species niches and distributions. From a set of environmental (e.g., climatic) grids and georeferenced occurrence localities (e.g. mediated by GBIF), the model expresses a probability distribution where each grid cell has a predicted suitability of conditions for the species.

Biodiversity Datasets Assessment Tool (BIDDSAT)

This website is a basic online PBR visualization environment for the content of data publishers and/or collections within the GBIF network. The tools here allow exploring the content of such datasets as a whole and find patterns or biases that may impact their quality or usability. The visualizations could be used to detect potential errors, allowing data publishers to fix the issues at the source. In order to enable historical comparisons and track error correction, data from several versions of the index are accessible.
