Term
| Aspects of Female Distribution Patterns (3) |
|
Definition
Resource distribution
Risk of predation
Benefits of group living |
|
|
Term
|
Definition
| male and female have only a single mating partner per breeding season |
|
|
Term
| Ecological Circumstances Favoring Monogamy (3) |
|
Definition
Necessary biparental care
Distribution of females
Mate guarding |
|
|
Term
|
Definition
| One male mates with more than one female during a breeding season |
|
|
Term
| Circumstance Favoring Polygny |
|
Definition
| A male benefits by producing more offspring. |
|
|
Term
| Polygyny Threshold Hypothesis |
|
Definition
| Benefits of mating with high quality mate compensate for the cost. |
|
|
Term
| Best Alternative Hypothesis |
|
Definition
| Best of all available options |
|
|
Term
|
Definition
| Access to good genes compensates for the costs. |
|

Term
|
Definition
| the difference in a territory’s quality that make secondary status a better reproductive option for females |

Term
| Resource Defense Polygyny |
|
Definition
| Males defend resources essential to female reproduction |
|
|
Term
| Conditions for Resource Defense Polygyny (4) |
|
Definition
Patchy habitat
Quality of the monopolized resource reflects male quality
Females prefer males with resources over those without
Males with resources have higher mating and reproductive success (higher quality territory -> more females) |
|
|
Term
|
Definition
| a male defends a harem of females. |
|
|
Term
|
Definition
| males will attempt to outrace each other to potential mates. |
|
|
Term
|
Definition
| Males defend symbolic territories while not providing parental care. |
|
|
Term
|
Definition
| No moale parental care. No resource on territory. Males aggregate and display at traditional sites. |

Term
|
Definition
| With such strong selection how do you maintain the bad genes? |
|
|
Term
| Solution to lek paradox (2) |
|
Definition
Genetic variation must persist for ornamental traits and genetic quality.
Ornament expression depends on condition. |
|
|
Term
|
Definition
| Female has more than one mate during the breeding season. |

Term
| Ecological reasons for polyandry (3) |
|
Definition
Rich resource, eggs are cheap
Short breeding season
Male biased sex ratio |
|
|
Term
| Optimal Mating System for Females |
|
Definition
| Polyandry is always optimal. However as the environment increases, monogamy followed by polygyny close the gap. |
|
|
Term
| Optimal mating system for Males |
|
Definition
| As environmental quality increases, polyandry followed by monogamy, followed by polygyny. |
