Q

what is the primate diet?

A
  • omnivores (animals and plants)
  • food factors (abundance, distribution, and quality)
  • highly quality foods are less abundant, patchy

Q

what are predation avoidance tactics in primates?

A
  • crypsis (avoiding detection, camoflouge)
  • nocturnal behavior

Q

what is dispersal?

A

to leave one’s group/area.

17
Q

what is fission-fusion?

A
  • societies in which group composition is flexible, such as chimpanzees and spider monkeys
  • individuals may break up into smaller groups or combine into larger ones
18
Q

why do primates live in groups?

A
  • feeding competition (dominance hierarchy reduces aggression)
  • females in larger groups had shorter birth intervals
  • intergroup conflict (larger groups are more successful)
  • predation avoidance
19
Q

what are polyspecific associations?

A

an association between two or more different species that involves behavioral changes in at least one of them to maintain the association.

20
Q

what does it mean to be philopatric?

A

remaining in one’s birth group.

21
Q

what is parental investment?

A

spending more time with current offspring to ensure that they survive at the expense of other potential offspring.

22
Q

what is sexual selection?

A

selection of traits that increase mating success.

23
Q

what is intrasexual selection?

A

selection of traits that enhance the ability of members of one sex to compete amongst themselves.

24
Q

what is intersexual selection?

A

selection of traits that enhance the ability of members of one sex to attract the attention of the other.

25
what is a social system?
way of describing the typical number of males and females of all age classes that live together.
26
what is monogamy?
- mating system with one male and one female - gibbons - low sexual dimorphism
27
what is polygyny?
- mating system with one male and multiple females - orangutans - high sexual dimorphism
28
what is polyandry?
- mating system with multiple males and one female - tamarins and marmosets
29
what is polygamy?
multiple males mate with multiple females.
30
what is vocal primate communication?
- loud calls, screeches - semantic communication (use of signals to refer to objects in the environment)
31
what is visual primate communication?
- facial expressions - piloerection (raising one's hair to look bigger) - sexual swelling - facial coloration
32
what is olfactory primate communication?
- anogenital scents - urine washing
33
what is tactile primate communication?
- grooming - affiliative (non-aggressive social interactions between individuals)
34
what is culture?
- transmission of behavior via social learning - in humans it is shared, symbolic, and learned - in chimpanzees, includes population-specific pray preferences, tool-use techniques, hunting strategies, and social behaviors - in macaques, unique foraging behaviors and hot springs bathing.
35
what are cultural traditions?
a distinctive pattern of behavior shared by multiple individuals in a social group, which persists over time and is acquired through social learning.
