⚠️There's a newer version (2.0.0) of this package.Take me there.

MetaLandSim (version 0.2)

Metapopulation and Landscape Simulation

Description

Tools to generate random landscape graphs, evaluate species occurrence in dynamic landscapes, simulate future landscape occupation and evaluate range expansion when new empty patches are available (e.g. as a result of climate change).
