anything organisms do that involves action in response to internal or external stimuli

the composition, size, and sex ratio of a group of animals

the study of the evolution of behavior, emphasizing the role of ecological factors as agents of natural selection

the chemical processes within cells that break down nutrients and release energy for the body to use

groupings of females who are all descendants of one female

remaining in one's natal group or home range as an adult

characteristics and developmental stages that influence rate of reproduction

behaviors or behavioral complexes that have been favored by natural selection because they're advantageous to the animals that perform them

living in the same area; pertaining to two or more species whose habitats partly and largely overlap

the total area exploited by an animal or social group, usually given for one year or for the entire lifetime of an animal

the complex of behavioral patterns that contributes to individual reproductive success

members of the same species

systems of social organization wherein individuals within a group are ranked relative to one another

any act that conveys information, in the form of a message, to another individual

pertaining to physiological responses that aren't under voluntary control

picking through fur to remove dirt, parasites, and other materials that may be present

sequences of repetitious behaviors that serve to communicate emotional states

behaviors removed from their original context and sometimes exaggerated to convey information

pertaining to amicable associations between individuals

within the group, as opposed to between groups

the complex behavioral patterns that contributes to individual reproductive success

pertaining to k-selection, an adaptive strategy whereby individuals produce relatively few offspring, in whom they invest increased parental care

pertaining to r-selection, an adaptive strategy that emphasizes relatively large numbers of offspring and reduced parental care

a type of natural selection that operates on only one sex within a species

a mating system characterized by an association between a female and more than one male with whom she mates

a common behavior in many primate species whereby individuals other than the parent(s) hold, carry, and in general interact with infants
