Document Summary
Action carried out by muscles under control of nervous system. Set of adaptation that equip animal for survival in a particular environment. Behavioral ecology study of the ecological and evolutionary basis for animal behavior. Suggested that understanding any behavior requires answering four questions. How a behavior occurs or is modified. Photoreceptors stimulated for longer period of time. Why a behavior occurs in the context of natural selection. Time when breeding most productive or adaptive. H2o warm and food abundant allow fast growth of young. Fish breeding in spring probably more offspring than fish breeding in the fall, winter, or late summer. Sensory input = stimulus that triggers behavior. Sequence of unlearned behavior in response to a simple stimulus. A fixed action pattern is triggered by an external cue known as a sign stimulus. The position of the sun and their circadian clock, and internal 24- hour clock that is an integral part of their nervous system.
