Maximum Entropy Modelling (MAXENT)

Brief Description

Uses the external MAXENT modelling tool (Phillips et al. 2006) to predict a species distribution using presence-only data for a given extent. This software takes as input a set of layers or environmental variables (such as elevation, precipitation, etc.), as well as a set of georeferenced occurrence locations, and produces a model of the range of the given species.

A tutorial how to work with MAXENT can be found in the attached literature or on the website of the authors.
