Another approach we take towards understanding the Allee effect is to look for statistical “signatures” in population dynamics, i.e., patterns in population abundance or distribution…

Background. Recent studies on animal populations in the field have attributed positive-density dependence at low density to a predator-driven Allee effect (e.g. Wittmer et al….
