Aim
To evaluate the effect of biogeographical history on climatic niche diversification.
Location
Simulated clades evolving in South America.
Methods
We modelled species evolution under neutral community dynamics and purposely assumed that climatic niche is an emergent property of species. This assumption allows us to better understand whether phylogenetic niche conservatism could be observed...
Recent years have witnessed a growing interest in understanding the evolution of social behaviour in heterogeneous spatially structured populations. These studies, however, have neglected the impact of extinction–colonisation dynamics and ecological succession on the dynamical expression of social behaviour over time. Here, I present a kin‐selection model in which patches are structured into age‐classes...
Since the inception of modern social evolution theory, a vast majority of studies have sought to explain cooperation using relatedness‐driven hypotheses. Natural populations, however, show a substantial amount of variation in social behaviour that is uncorrelated with relatedness. Age offers a major alternative explanation for variation in behaviour that remains unaccounted for. Most natural populations...
There has been much interest in understanding how demographic factors can mediate social evolution in viscous populations. Here, we examine the impact of heterogeneity in patch quality—that is, the availability of reproductive resources for each breeder—upon the evolution of helping and harming behaviors. We find that, owing to a cancellation of relatedness and kin competition effects, the evolution...
