0th

Percentile

Niche Expansion, Stability, and Unfilling

Calculate niche expansion, stability and unfilling.

Usage
ecospat.niche.dyn.index (z1, z2, intersection=NA)
Arguments
z1

A gridclim object for the native distribution.

z2

A gridclim object for the invaded range.

intersection

The quantile of the environmental density used to remove marginal climates. If intersection=NA, the analysis is performed on the whole environmental extent (native and invaded). If intersection=0, the analysis is performed at the intersection between native and invaded range. If intersection=0.05, the analysis is performed at the intersection of the 5th quantile of both native and invaded environmental densities.

Details

If you encounter a problem during your analyses, please first read the FAQ section of "Niche overlap" in http://www.unil.ch/ecospat/home/menuguid/ecospat-resources/tools.html

Value

A list of dynamic indices: dynamic.index.w [expansion.index.w, stability.index.w, restriction.index.w]
