EXAM TUESDAY
| Question | Answer |
|---|---|
| what is socioecology | the study of how environmental variables affect the primates group size, composition, and social dynamics |
| what are the enviromental variables | feeding ecology, predation, disease, infanticide, dispersal risk and cooperation |
| what are the activity patterns | Diurnal, nocturnal, cathemeral (sporadic), crepuscular (dawn and dusk) |
| what are the habitat preference | arboreal, terrestrial, semi-terrestrial |
| what are the Dietary categories | folivore (leaves), frugivore (fruits), insectivore, gramnivore (grains), gumnivore (sap and gum of plants) |
| what are the group size and composition | solitary vs. gregarious, ratio of number males to females |
| what are the Mating system | polygynous (1m with multiple f), monogamous, polyandrous (1f with multiple m), promiscuous |
| which mating system is the most common | polygynous |
| what are the ranging pattern | home range, day range, core area, territoriality |
| what are the dispersal patterns | female philopatric, male philopatric, neither sex philopatric (both disperse at sexual maturation)\ |
| what's common about solitary primates | they tend to be nocturnal |
| what's common about terrestrial primates | they tend to have larger group |
| what's common about nocturnal | they tend to be smaller than diurnal |
| Eating ranges of frugivores vs folivores | frugivores have large range than folivores |
| what is sexual dimorphism | differences between morphology of different genders of primates |
| what is the well established correlations about sexual dimorphism | Sexual dimorphism increases with increasing group size when females outnumber males |
| what was Darwin's theory | Intra-Sexual selection (male-male competition) Inter-sexual selection (female choice) |
| what was fisher and hamilton's theory | Inclusive fitness Kin selection |
| what was Wranghman's theory | Intergroup feeding competition is the key driver of evolution of primate grouping patterns -male follows female |
| Wrangham's model | Food 1. Defensible--Large Group--Female philopatry 2. Nondefendsible--Small Group--No female philopatry |
| who takes wranghma's model to the next level | van Schaik |
| what are the two complexities van Schaik add to Wrangham's model | 1. predation pressure 2. feeding competition |
| what are predation pressure | upper and lower limit group size |
| what is the upper limit group size set by | feeding competition |
| what is the lower limit group size set by | predation pressure |
| what are the complexities of feeding competition | Contest or interference competition Scramble competition Within groups vs. between groups |
| what are the contemporary perspective | 1. pop density 2. predation pressure 3. resource distribution |
| what is behavioral disequilibrium | Habitat fragmentation or saturation may lead to non-adaptive behaviors within populations |
| what is the cause of habitat fragmentation | deforestation |
