what is the body size-diet relationship for small bodies?
- less than 500g
- fast metabolism
- eats proteins, fats, insects, sap
what is the body size-diet relationship for large bodies?
- more than 500g
- slower metabolism
- eats mature leaves
what is the locomotion-body size relationship for small bodies?
- run on top of branches
- leap
- IMI = or < 100
what is the locomotion-body size relationship for large bodies? (Hole In Sock)
- hang under branches
- swing
- IMI > 100
how do you calculate intermembral index (IMI)
arm length/leg length * 100
what are 4 forms of primate locomotion
- vertical clinging & leaping
- quadrupedalism
- brachiation (suspensory)
- bipedalism
what is monogamy & what does it entail (3)
- form of primate social org
- males & females mate
- LESS sexual dimorphism
what are single male (“uni-male”) groups
1 adult male, many females
what are multi-male/female groups
many adult males & females
what is a polyandrous group
mating of 1 female with more than 1 male
what is solitary?
one individual defending a territory
what is ecological niche
role & position a species has in their environment (how it meets needs for food, shelter, survives & reproduces)
what is territory
area inside a home range
- aggressively defended against intrusion, especially by con-specifics (members of same species)
what is home range
- total area used by an organism or social group of organisms
what is primate socio-ecology
behavior within environment
what is social organization
means by which organisms adjust to their environment
what are dominance hierarchies (3)
- hierarchy of ranked statuses sustained by hostile behavior
- threat, but rarely physical violence
- there can be female dominance
what is grooming used for?
establishing alliance, a “currency”
what do field studies of chimpanzees show?
they participate in protoculture: tool making to fish for termites
how does hunting work for chimpanzees?
- they hunt antelopes
- males hunt, females DIRECT hunting
what is protoculture?
- passing of behavior down generations among NON-HUMAN primates
- shared meanings, NOT genetic-based
did human beings evolve from chimpanzees?
no, we have COMMON ANCESTORS
