Speciation, adaptation and morphological diversification; Evolution and genetics of butterfly wing patterns
I have a broad interest in biology encompassing the fields of natural selection theory, genetics, population and community ecology, and conservation biology. The long-term goal of my lab is to study the organization of biological diversity, the selective processes that shape its evolution, and the means to preserve it in the Indian Region. We specifically use two systems as microcosms to study a range of phenomena that fascinate us, such as morphological evolution, sexual dimorphism and polymorphism, geographical distribution of animals, and speciation.
Our first study system is Batesian mimicry, which is a phenomenon whereby unprotected prey species (called “mimics”) gain protection from predators by mimicking toxic or otherwise protected species (called “models”). Predators learn to avoid models based on prior experience, and subsequently avoid eating mimics due to misidentification. Hundreds of mimetic insects, and especially butterflies, are known from tropical forests. There is tremendous variation in Batesian mimicry: mimicry can be sexually monomorphic, polymorphic or sex-limited within and across species. Our research aims to understand selective pressures that favor such variation in mimetic color patterns, and uncover its genetic basis. Read more about this work on our lab website.
Our second study system is Indian butterflies. India’s butterfly diversity is spread across four globally recognized biodiversity hotspots, and it offers virtually unlimited opportunities to study biogeography, community ecology, population biology and conservation issues. Some Indian butterfly species also exhibit seasonally variable wing patterns, large-scale annual migrations, and phenomenal boom-and-bust population cycles, which make them excellent model organisms to address a wide variety of scientific problems. We study all these phenomena as part of our various ongoing projects. Read more on our lab website.
