Abstract

Caughley’s contributions to single-species population ecology are here discussed in the light of some of the ideas and studies his work elicited, with particular reference to influences on my own work and that of my collaborators. Major themes are the manner and extent of population regulation; the alternate perspectives on population regulation that are obtained by density-dependence analyses and mechanistic analyses in terms of food availability and other causal factors; and ways in which mechanistic analyses can be elaborated to characterise a species’ ecological niche and relate it to the species’ geographic range.
