BIOL 150 Chapter Notes - Chapter 53: Proximate And Ultimate Causation, Eusociality
Document Summary
Behavioral ecology - study of how organisms respond to particular stimuli from their environments. Circadian clock - a clock that exists in organisms/animals that maintains a 24-hour rhythm of chemical activity. Coefficient of relatedness - measure of hose closely the actor and beneficiary are related; r measures the fraction of alleles in the actor and beneficiary that are identical by descent -- that is inherited from the same ancestor. Communication - process in which one individual modifies the behavior of a recipient individual; crucial component of animal behavior, as it creates a stimulus that elicits a response. Compass orientation - movement that is oriented in a specific direction. Cost-benefit analysis - a framework that biologists use to link condition-dependent behavior to fitness. Eusociality - phenomenon where workers sacrifice most or all of their direct reproduction to help rear the queen"s offspring (in society) Fixed action patterns (faps) - highly inflexible, stereotyped behavior patterns.
