Evolutionary Assembly and Ecological Dynamics of Butterfly Mimicry Rings

The hallmark of life on earth is morphological diversity, which is represented in the spectacular sexually dimorphic and polymorphic wing patterns of butterflies. I will address the evolutionary patterns and ecological processes that govern diversification in well-defined mimetic communities called mimicry rings. I will show how phylogenetic conservatism and convergence shape the evolutionary dynamics of mimicry rings. I will elucidate the role that island biogeographic processes play in the diversity and composition of mimicry rings. Finally, I will present a simple model that explains how sexual selection and frequency-dependent predation influence diversification of mimicry types, especially in sex-limited and polymorphic forms.
I will spend the last 10 minutes talking about the biodiversity museum and research collections that we are developing at NCBS, which will facilitate biodiversity-related research in India.
