Behavioural and neurological aspects of ecological adaptation and speciation

Organized by

Stephen Montgomery and Richard Merrill

It is now widely accepted that adaptation to different ecological niches can result in the evolution of new species. As such, a major goal of evolutionary biology has been to characterize the adaptations between populations that contribute to ecological divergence and speciation. Although most studies have concentrated on structural adaptations, such as colour pattern, shifts in behaviour may be especially important in generating both reproductive and ecological isolation. These behavioural differences may be genetically determined or acquired (learnt). Behavioural plasticity has been shown to allow short-term adjustments to environmental change and it has been suggested that plasticity in host-use may facilitate speciation in butterflies. However, models suggest the benefits of plasticity are transitory and may only increase fitness during the initial colonization of new niches, raising questions over the relative contribution of plasticity and genetically determined differences in behaviour to ecological adaptation and speciation.
