Throughout their lives animals must complete many tasks‎,‎ including finding food‎,‎ avoiding predators‎,‎ attracting mates‎,‎ and navigating through a complex and dynamic environment‎.‎ Consequently‎,‎ they have evolved a staggering array of sensory organs that are fundamental to survival and reproduction and shape much of their evolution and behaviour‎.‎ Sensory ecology deals with how animals acquire‎,‎ process‎,‎ and use information in their lives‎,‎ and the sensory systems involved‎.‎ It investigates the type of information that is gathered by animals‎,‎ how it is used in a range of behaviours‎,‎ and the evolution of such traits‎.‎ It deals with both mechanistic questions ‎(‎e‎.‎g‎.‎ how sensory receptors capture information from the environment‎,‎ and how the physical attributes of the environment affect information transmission‎)‎ and functional questions ‎(‎e‎.‎g‎.‎ the adaptive significance of the information used by the animal to make a decision‎)‎‎.‎ Recent research has dealt more explicitly with how sensory systems are involved with and even drive evolutionary change‎,‎ including the formation of new species‎.‎ Sensory Ecology‎,‎ Behaviour‎,‎ and Evolution provides a broad introduction to sensory ecology across a wide range of taxonomic groups‎,‎ covering all the various sensory modalities ‎(‎e‎.‎g‎.‎ sound‎,‎ visual‎,‎ chemical‎,‎ magnetic‎,‎ and electric‎)‎ relating to diverse areas spanning anti‎-predator strategies‎,‎ foraging‎,‎ mate choice‎,‎ navigation and more‎,‎ with the aim being to illustrate key principles and differences‎.‎ This accessible textbook is suitable for senior undergraduates‎,‎ graduate students‎,‎ and professional academics taking courses or conducting research in sensory ecology/biology‎,‎ neuroethology‎,‎ behavioural and evolutionary ecology‎,‎ communication‎,‎ and signalling‎.‎ It will also be of relevance and use to psychologists interested in sensory information and behaviour‎.‎
