Population abundance data and species range maps

Mathieu Chevalier, Olivier Broennimann & Antoine Guisan
Aim – The abundant-center hypothesis (ACH) predicts a negative relationship between species abundance and the distance to geographic range center. Since its formulation, empirical tests of the ACH have involved different settings (e.g. the distance to the ecological niche or to the geographic range center), but studies found contrasting support for this hypothesis. Here, we evaluate whether these discrepancies might stem from differences regarding the context in which the ACH is tested (geographical or environmental),...
