Flashcards in Animal Behavior Deck (17):
1

Kinesis

Seemingly random change in speed of a movement on response to a stimulus
An organism slows down in an environment it enjoys and speeds up in an environment it dislikes

2

Inclusive Fitness

Overall ability of individuals to pass their genes on to the next generation

3

Optimal Foraging

Natural selection favors animals that choose foraging strategies that take into account costs and benefits

4

Territoriality

Defense of territory to keep others out

5

Foraging

Feeding behavior of an individual
Animals have a search image that directs them to food

6

Coefficient of Relatedness

Statistic that represents the average proportion of genes that two indiduals have in common
Siblings have a coefficient of 0,5 since they share 50% of their genes

7

Dominance Hierarchy

Ranking of power among the members of a group

8

Reciprocal Altruism

Animals behave altruistically toward others that are not relatives, hoping that the favor will be returned sometime in the near future

9

Altruistic Behavior

Behavior by which an organism does something to help another, even if it comes at its own expense

10

Agnonistic Behavior

Behavior that results from conflicts over resources
Often involves intimidation and submission
Frequently involves food, mats and territory
Rarely results in injury because most agonistic interactions are just displays.

11

Associative Learning

Process by which animals take one stimulus and associate it with another

12

Fixed Action Pattern

Innate, preprogrammed response to a stimulus
Once this action has begun, it will not stop until it has run its course
Example: Male Stickleback fish are programmed to attack any red-bellied fish they see.

13

Habituation

Loss of responsiveness to unimportant stimuli through repeated exposure

14

Imprinting

Innate behavior that is learned during a critical period early in life

15

Insight Learning

Ability to do something right the first time with no prior experience

16

Observational Learning

Ability of an organism to learn how to do something by watching another individual do it first

17

Operant Conditioning

Type of associative learning that is based upon trial and error
An association is made between the animal's own behavior and a response
