isoniche - Isodar-Adjusted, Abundance-Independent Niche Breadth
Estimates habitat niche breadth corrected for the effects
of abundance, using isodars (the relationships between a
species' densities in pairs of habitats under density-dependent
habitat selection). Fits pairwise and n-dimensional isodars,
including data where sites lack some habitats, and computes the
isodar-adjusted inequality (IAI) at any total abundance, with
density-independent and density-dependent niche breadth,
bootstrap confidence intervals and diagnostics. Method
described in Granot, Dubiner and Belmaker (in revision, Ecology
Letters).
