Despite the importance of population structures throughout ecology, relatively little
theoretical attention has been paid to understanding the implications of social groups for …

Using the theory and methods of non-linear dynamics, I explore the consequences of
cooperation on the size and dynamics of social groups. I present a model that incorporates …

Using an individual-based and genetically explicit simulation model, we explore the
evolution of sociality within a population-ecology and nonlinear-dynamics framework …

Much of the literature on social evolution is pervaded by the old debate about the relative
merits of kin and group selection. In this debate, the biological interpretation of processes …

Allee effects in group‐living species are common, but little is known about the way in which
Allee effects at the group‐level scale up to influence population dynamics. Most notably, it …

Social vertebrates commonly form foraging groups whose members repeatedly interact with
one another and are often genetically related. Many species also exhibit within‐population …

The contribution of local (eg, competition) and regional (eg, dispersal) processes in the
structure of communities remains an unresolved issue. In general, a tendency to assume …

Natural ecological communities are diverse, complex, and often surprisingly stable, but the
mechanisms underlying their stability remain a theoretical enigma. Interactions such as …

Most models of theoretical population ecology consider population density as a state
variable and thus ignore the fact that populations are composed not of identical average …

In animal societies, kin selection is a critical evolutionary process, with cooperation evolving
principally among relatives living in kin-structured populations. Theoretical and empirical …
