The acquisition and transduction of environmental information will be explored in the context of decision making and adaptive behaviour. This course will focus on the form and function of visual, auditory, tactile, and chemical senses and signals, and animal communication writ large. Post-acquisition, cognitive processes concerned with learning and memory will also be discussed. A comparative approach will be taken throughout to examine the ways that different animals and animal groups rely on different sources of information and a diverse variety of sensory and cognitive mechanisms. All topics will be covered in the context of species-specific ecology and evolution.
