isoniche - Calculating Density-Independent Niche Breadth Indices from
Abundance Data
Deriving density-independent and density-dependent niche
breadth indices from abundance data of two or more habitats,
including both the pairwise and n-dimensional methods to
calculate isodar-adjusted inequality. Methods are described in
Granot, Dubiner & Belmaker (in revision), "Why abundance-based
indices of niche breadth are biased, and what can be done to
improve them", Ecology Letters.
