Ecological niche modeling has fast become an extremely popular methodology in the use, exploration, and analysis of biodiversity data. As a tool, niche modeling offers the possibility of understanding species’ geographic distributions (actual and potential) in detail, as well as an understanding of species’ environmental requirements (i.e., the ecological niche). Although tools for niche modeling are now widely and freely available, a clear and appropriate thinking framework for the use of the tool is often not in hand, leading to many partial or inappropriate implementations. This course is designed to provide in-depth training in the use of niche modeling as an approach to biodiversity data. Instructors include Richard Pearson, Enrique Martinez-Meyer, and Town Peterson, all leaders in this field in North America.
