Variability in sensory ecology: expanding the bridge between physiology and evolutionary biology.

Sensory organs represent the interface between the central nervous system of organisms and the environment in which they live. To date, we still lack a true integration of ecological and evolutionary perspectives in our understanding of many sensory systems. We argue that scientists working in sensory ecology should expand the bridge between sensory and evolutionary biology, and, in working toward this goal, we advocate a combination of the experimental rigor of the sensory physiologist with population-based as well as evolutionary views.
