Demographic Approach to Species Distribution Model R package xsdm version 1.0.2 Integrates concepts of stochastic demography into species distribution modelling. The main approach maximizes a likelihood function based on environmental information and presence/absence records. This is used to reconstruct species' fundamental ecological niches and to project their potential geographic range. Data requirements include species presence/absence records and a timeseries of environmental data.
