TEXT: Sensory Ecology: how organisms acquire and respond to information, D. Dusenbery, W.H. Freeman and Company, 1992.


SUPPL. TEXTS: Principles of Animal Communication, Bradbury and Vehrencamp, Sinauer Associates, Inc, MA, 1998.



This course consists of quantitative analyses of communication channels from signal structure, generation, propagation, detection, to the animal response and the consequent effects on ecological interactions. We will focus on the physical basis of signal propagation, perception and information acquisition and ask how this knowledge helps us understand ecological problems. The approach will be broadly comparative, examining visual, auditory, mechanosensory, and olfactory sensory modalities across a range of vertebrate and invertebrate species in aquatic and terrestrial habitats.
