Campbell Biology Chapter 51: Animal Behavior
| Question | Answer |
|---|---|
| Proximate | These questions focus on the environmental stimuli that trigger a behavior and the genetic/ physiological/ anatomical mechanisms that govern the behavior. |
| Ultimate | These questions address the evolutionary significance of behavioral responses. |
| Fixed action pattern | A sequence of unlearned behavioral acts that is essentially unchangeable and is usually carried to completion. An example is a red object prompting the male stickleback’s aggressive behavior. |
| Habituation | A loss of responsiveness to stimuli that convey little or no information. |
| Imprinting | A type of behavior that includes both learning and innate components and is generally irreversible. In this behavior, the young offspring can be taught to follow something other than the parent. |
| Taxis | A more or less automatic, oriented movement toward or away from some stimulus. |
| Kinesis | A simple change in activity in response to some stimulus. |
| Types of animal communication | 1. Visual 2. Chemical 3. Tactile 4. Auditory |
| Pheromones | Chemical substances important in animal communication. |
| Spatial learning | A type of learning in which behavior if modified based on experience with the spatial structure of an environment. |
| Associative learning | A type of learning in which the animals match one feature of the environment (a stimulus, such as color) with another (such as taste). |
| Learning | The modification of behavior as a result of specific experiences. |
| Optimal foraging theory | Views feeding behavior as a compromise between the benefits of nutrition and the costs of obtaining food. |
| Monogamous | A type of relationship that involves one male mating with one female. |
| Polygamous | A type of relationship that involves an individual of one sex mating with several of another sex. |
| Polygyny | A relationship involving one male and many females. |
| Polyandry | A relationship involving one female and many males. |
| Game theory | A method that evaluates alternative strategies in situations where the outcome depends not only on each individual’s strategy but also on the strategies of other individuals. |
| Altruism | A behavior that may reduce an individual’s fitness but increase the fitness of other individuals in the population. |
| Mate choice copying | When individuals in a population copy the mate choice of others, instead of some generally preferred type. |
