The Mirth Lab


Our lab studies the regulation and evolution of environmentally-dependent traits in species from the genus Drosophila. Recently, our efforts have focused on two traits that depend on nutritional cues:

        1) Body and Organ Size,

        2) Larval Foraging Behaviour.

We use the genetic tools available in Drosophila melanogaster to dissect how environmental signals, like nutrition, regulate larval growth and foraging choices. By analyzing the changes in these mechanisms across species, we hope to identify how these environmentally-dependent traits evolve to create species-specific differences in foraging behaviour and adult body size.
