There is no artefact

Webb, T.J., Freckleton, R.P. & Gaston, K.J. 2012. Characterising abundance-occupancy relationships: there is no artefact. Global Ecology & Biogeography 21, 952-957.

A short piece logically and empirically refuting a recent suggestion that interspecific relationships between local abundance and regional occupancy are often artefactual. Rather, these patterns remain fundamentally important descriptors of the structure of species assemblages.
