Female Strategies Flashcards
Under what conditions do females compete for males?
When males provide a valuable resource or service, such as protection or food access
What evidence supports the link between food and female reproductive success?
- Provisioned colonies: higher reproductive output
- Amenorrhea in low body fat females
3 key variables affecting female feeding behavior
Food quality, spatial distribution, temporal availability
2 types of food competition in females
Scramble(non-aggressive) and Contest(aggressive)
2 continuums of female social relationships
- Egalitarian-Nepotistic (is there a dominance hierarchy)
2.Depostic-Tolerant(Rigidity of the hierarchy)
Dispersal-Egalitarian relationship
*within-group competition: LOW
*Between-group competition: LOW
*no dominance hierarchy
Resident-Egalitarian relationships
*Within-group competition: LOW
*Between-group competition: HIGH
*No dominance hierarchy
Resident-Nepotistic relationships
*Within-group competition = HIGH
*Between-group competition = LOW
*Dominance hierarchy based on kinship
Resident-Nepotistic-tolerant
*Within-group competition = HIGH
*Between-group competition = HIGH
*Reversals may occur
What is a matrilineal hierarchy
*Daughters inherit their mother’s rank
*rank based on birth order
*sons leave the group
What is the Priority of Access Model
higher-ranked females should have greater RS
