Drosophila Ecologist

Tropical drosophilids are adapted to cope with contrasting demands of seasonally varying environments on the physiology and behavior
• Conservation of diversity is a global priority
• To understand species distribution patterns is an important goal
• Tools include evolutionary physiology, spatial and temporal ecology, invasion biology
• In the field, we study stress related traits in different species and also in different geographical populations within a species.
Novel findings of the laboratory:
• Melanisation – desiccation hypothesis to explain the occurrence of melanics in the tropics.
• Opposite clines for desiccation and starvation tolerance.
• Warm adapted species D. jambulina lacks genetic structure for different quantitative traits.
