Angela McGaughran, Katy Morgan and Ralf J. Sommer Natural variation in chemosensation: lessons from an island nematode Ecology and Evolution 3
Understanding the evolutionary forces that shape natural systems requires characterization of phenotypic traits in an ecological context. We examine chemosensation in the nematode, Pristionchus pacificus, and find that strains show extreme variation in their odor-guided behavior. This variance has a strong ecological component.
