Body size and shape are characteristic and often distinguishing features of animal groups. Size and shape not only varies between distantly related animals, but also between closely related species. Furthermore, within a species we frequently observe both genetic and environmentally-induced variation in body size and shape.
Changes in abiotic environmental conditions alter the trajectories of developmental programs, sometimes producing dramatic differences in animal shape. Finally, choices made throughout the life cycle can profoundly affect adult body size and shape.
We are interested in understanding the molecular mechanisms that underlie environmentally- and genetically-induced variation in body size and shape.
