Ecological - Version Biotas -Statistical and GIS Tool
Biotas is a statistical and GIS tool for Windows written for ecologists and resource professionals. Biotas has been designed to assist in the analysis and understanding of spatial and temporal data. Studies that can benefit from Biotas include, but not limited to, those dealing with wildlife, fisheries and plant or animal ecology. Functions include home range, habitat use, movements, nearest neighbors, spatial randomness tests and more.
