Drosophila Olfactory Neuroecology - Function and Evolution

The olfactory system of an animal is adapted to its ecological niche. Colonization of a novel niche often leads to the encounter of novel sensory information, which then has to be accurately and efficiently assessed in order for the animal to be competitive. Adaptations may result in speciation. To what extent will these processes affect the olfactory sense? Will the new species keep ist ancestral olfactory system or will it evolve a unique set-up, adapted to the conditions of the novel niche? An excellent model system for such studies is the Drosophila mojavensis cluster. This cluster includes three species, D. navajoa, D. mojavensis and D. arizonae. They are geographically isolated and all are endemic to the arid lands and deserts of United States and Mexico. In addition, their phylogenetic relationships and ecology are well understood. In this study, I will characterize the olfactory system of this cluster; morphologically and electrophysiologically.
