Animal Behavior

Terms : Hide Images
3524195054Agonistic BehaviorIn animals, an often ritualized contest that determines which competitor gains access to a resource, such as food or mates.0
3524195055AltruismSelflessness; behavior that reduces an individual's fitness while increasing the fitness of another individual.1
3524195056Associative LearningThe acquired ability to associate one environmental feature (such as a color) with another (such as danger).2
3524195057Behavioral EcologyThe study of the evolution of and ecological basis for animal behavior.3
3524195058Classical ConditioningA type of associative learning in which an arbitrary stimulus becomes associated with a particular outcome.4
3524195061EthologyThe scientific study of how animals behave, particularly in their natural environments.5
3524195062Fixed Action Pattern (FAP)In animal behavior, a sequence of unlearned acts that is essentially unchangeable and, once initiated, usually carried to completion.6
3524195063HabituationA simple type of learning that involves a loss of responsiveness to stimuli that convey little or no new information.7
3524195064ImprintingIn animal behavior, the formation at a specific stage in life of a long-lasting behavioral response to a specific individual or object. (See also genomic imprinting.)8
3524195065Innate BehaviorAnimal behavior that is developmentally fixed and under strong genetic control. This is exhibited in virtually the same form by all individuals in a population despite internal and external environmental differences during development and throughout their lifetimes.9
3524195066KinesisA change in activity or turning rate in response to a stimulus.10
3524195067LearningThe modification of behavior based on specific experiences.11
3524195069Operant ConditioningA type of associative learning in which an animal learns to associate one of its own behaviors with a reward or punishment and then tends to repeat or avoid that behavior; also called trial-and-error learning.12
3524195070Optimal foraging TheoryThe basis for analyzing behavior as a compromise between feeding costs and feeding benefits.13
3524195071PheromoneIn animals and fungi, a small molecule released into the environment that functions in communication between members of the same species. In animals, it acts much like a hormone in influencing physiology and behavior.14
3524195072PolyandryA polygamous mating system involving one female and many males.15
3524195073PolygamousReferring to a type of relationship in which an individual of one sex mates with several of the other.16
3524195074Reciprocal AltruismAltruistic behavior between unrelated individuals, whereby the altruistic individual benefits in the future when the beneficiary reciprocates.17
3524195075Sensitive PeriodA limited phase in an individual animal's development when learning of particular behaviors can take place; also called a critical period.18
3524195076Sign StimulusAn external sensory cue that triggers a fixed action pattern by an animal.19
3524195077SignalIn animal behavior, transmission of a stimulus from one animal to another. The term is also used in the context of communication in other kinds of organisms and in cell-to-cell communication in all multicellular organisms.20
3524195078TaxisAn oriented movement toward or away from a stimulus.21
