True or False: greater reproduction success is a material benefit from mate choice.
False
A mating system in which one female mates with ONLY one male and does not copulate with other males.
Genetic (true) monogamy
A mating system in which one female forms a lasting pair bond with one male, though she may also copulate with other males.
Social monogamy
A mating system in which one male mates with multiple females.
Polygyny
A mating system in which one female mates with multiple males.
Polyandry
An aggregation of males that engage in competitive mating displays toward visiting females is called a __________
Lek
A behavior in which one member of a pair presents his potential partner with food during courtship or before mating.
courtship feeding
True or False: female-to-female pair bonds do not exist.
False
A behavior in which a male attends closely to his mate during her fertile period to help ensure that she does not mate with other males.
mate guarding
A social bond between a mated pair (usually male and female) in a socially monogamous species, usually lasting for one breeding attempt or longer.
pair bond
Any physical trait that has been exaggerated for social display by sexual selection (usually refers to conspicuous traits involved in mate attraction).
ornament
A behavior in which one member of a pair provides less parental care in situations where the offspring in the nest may not be their own and/or when their mate also provides less care.
reproductive retaliation
True or False: monogamous species tend to occupy poor habitats where rearing offspring is difficult.
True (Polygynous species occur in resource-rich environments )
A hypothesis where males that have established a territory and have attracted a mate sometimes attempt to acquire a second territory with a second female.
Deceit hypothesis
The difference between a standard lek and an explosive lek is _____________________
Exploded leks are more spread out
A stereotyped posture adopted by female birds that indicates their readiness to copulate.
copulation-solicitation display
A hypothesis where females are lured into accepting sperm from persuasive male that has nothing of value to offer the female.
Empty Advertisement Hypothesis
Benefits of mate choice that stem from the high-quality genetic variants inherited by offspring of partners that choose genetically high-quality males.
Genetic benefits
A mating system in which one male is the predominant mate for multiple females, through defending territory or resources that attracts a group of breeding females.
Resource defense polygyny
A term for the process in which females mate with multiple males to help ensure that at least one partner is sexually fertile.
Fertility insurance
The pattern in which matings are distributed among males and females within a population, sometimes but not always involving longer term social bonds.
mating system
A special form of natural selection that involves the differential reproductive success of individuals that arises specifically from competition over mating opportunities.
sexual selection
A mating behavior between two members of a population who are NOT pair bonded (usually when each is socially pair bonded to a different mate).
Extra-pair copulation
A mating system in which one male is the predominant mate for multiple females, through defending that group of females against other males.
Female defense polygyny
True or False: the majority of avian species are polygynous.
False (majority of birds are socially monogamous)
