...These values are real numbers from 0 to 1, representing increasing degrees of “truth” regarding an organism’s membership in the fuzzy set (see main text). A value of 0 represents non-membership in the fuzzy set, and a value of 1 represents total membership in the fuzzy set. Values in between represent degrees of niche overlap.

Niche Analyst (NicheA) was developed based on the BAM framework which allows users to create virtual spaces and virtual species, and to analyze ecological niches in both multivariate environmental and geographic spaces, linking views of the niche in the two spaces. The unique functionality in NicheA, not available in other software programs, is estimating Grinnellian niches of species based on environmental variables and occurrence records, but with a clear focus on fundamental ecological niches. ...

BioSARN (Biological Species Approximate Realized Niche) refines environmental niche model output using topographic, soil and land class filtering, enhanced temporal corridor definition, niche area quantification and output to a high spatial resolution land class model. This is a Java™ Desktop MicroSoft Windows Application with a simple GUI. Preferably BioSARN should be used with 64-bit Java and a substantial RAM as the application reads input files into memory to minimize compute times.
