Abstract:Ecological Niche Models (ENMs) are often used to project species
distributions within alien ranges and in future climatic scenarios.
However, ENMs depend on species-environment equilibrium, which may be
absent for actively expanding species. We present a novel framework to
estimate whether species have reached environmental equilibrium in their
native and alien ranges. The method is based on the estimation of niche
breadth with the accumulation of species occurrences. An asymptote will
indicate exhaustive know… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
