Sensory Ecology, Evolution, and Behavior

itself is compara-tively recent, its basis has a long history, in part due to numerous links with subjects such as neurobiology, physiology, ethology, and evolutionary behavioral ecology. Studies of sensory ecology have also more re-cently incorporated other new techniques, such as those of molecular biology and phylogenetics. Sensory ecol-ogy deals with both mechanistic questions (for example, how receptors capture information from the environ-ment) and functional questions (for example, the adap-tive significance of the information gathered). It covers the full range of sensory systems and modalities. This special issue of
