The niche region is\ndefined as the joint probability density function of the\nmultidimensional niche indicators at a user-defined probability\nalpha (e.g., 95%). Uncertainty is accounted for in a Bayesian\nframework, and the method can be extended to three or more\nindicator dimensions. It provides directional estimates of\nniche overlap, accounts for species-specific distributions in\nmultivariate niche space, and produces unique and consistent\nbivariate projections of the multivariate niche region. The\narticle by Swanson et al. (2015) \nprovides a detailed description of the methodology.
