Document Summary
What is behavior: action carried out by muscles under control of nervous system, set of adaptations that equip animal for survival in particular environment, product of natural selection on phenotype, ways that maximize fitness. Behavioral ecology: study of the ecological and evolutionary basis for animal behavior. Niko tinbergen (dutch pioneer in study of animal behavior) How environmental stimulus determines different behavioral responses sensory input=stimulus that triggers behavior: a fixed action pattern, migration, behavioral rhythms, communication. 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, an internal 24 hour clock that is an integral part of their nervous system. If cloud covers both then use earth"s magnetic field. Breeding behaviors, migration and hibernation signals and communication signal= behavior that causes a change in another animals behavior communication is the transmission and reception of mutually recognizable signals.
