1	Mating System		_____	social associations and presumed mating behavior of individuals based on those associations
2	Sexual Conflict		_____	competition in which individuals compete indirectly with each other to find and secure copulations with multiple mates
3	Female Defense Polygyny		_____	predicts the occurrence of polygyny based on the amount of resources available to females in male territories
4	Resource Defense Polygyny		_____	actual number of sexual partners of each sex in a social mating system that contribute to a set of offspring
5	Male Dominance Polygyny		_____	a single male monopolizes and mates with two or more females
6	Territorial Cooperation Hypothesis		_____	selection favors males that mate with and guard one female over one or more reproductive cycles
7	Mate Guarding Hypothesis		_____	only a few males mate with most females
8	Polygyny Threshold Model		_____	two individuals, one of each sex, can better defend a critical resource; this favors pair formation and shared defenses
9	Hotspot Hypothesis		_____	copulations of a pair-bonded individual with a third individual outside the pair bond
10	Hotshot Hypothesis		_____	low-ranking males can benefit by aggregating around high-ranking males because females are more likely to visit attractive males
11	Scramble Competition		_____	all males can benefit by aggregating in a location where they are likely to encounter many females
12	Social Mating System		_____	description of the social associations and number of sexual partners an individual has during one breeding season
13	Genetic Mating System		_____	a male defends resources and mates with multiple females attracted to the resources
14	Extra-pair Copulations		_____	differential selection on males and females to maximize their fitness
15	Genetic Quality Hypothesis		_____	females that engage in multi-male mating can improve the fitness of their offspring via genetic mechanisms
