week 5 Flashcards
(21 cards)
captive studies
zoo encloseures
pros- easy to record
cons- innatural setting, meaningful data?
semi- free ranging
island, large enclosures
pros- easy to records
cons- often transplanted
medical studies
human modeks
eg. chimpanzes in AIDS/HIV research
pros- genically similar to human
cons- horrible for primates, is it ethinical?
field studies
pros- habitat the species envolved in
cons- diffcult for researcher - dangerous, long commitment
eg- trimates
jane goodall, diane fossey, birute goldkas
size and type
eg. large community of 300 males with harem and young pair bonds with young note can also be within a larger ocmmunity solitary
sexual behviour
monogamy, polygyny, polyandry
sxual dimorphism: text def: diffs in morphology, behvaiour, hormones, colozation
is this dimorphism: little, moderate, pronouce- craines, peacocks
rank
important?
male or female domianted?
aggresion
internal/external
how is it handled?
taxonomy
class: mammals
order: primates
suborder 1: strepirrhini (not monkeys)
2. haplorrhini
suborder; strepsirrhini
more rimitvie, arboreal, envolved independent from monkeys/ apes
eg. lemurs, lorises, galagos
charcteristics: sterpirrhini
rely on olfaction - nasal passages, scent glands, olfacory bulbs and rhiniarium
nocturnal - large eyes and lateral orbits
dental specialization eg. dental comb for gromming
2:1:3:3 dental formula - humans are 2:1:2:3
bredding season- litter, y shaped uterus
low brain to body ratio
grooming claw
sub order: haplorrhini
3 intra orders: trarsiiforms
playtyrrhini
catarhini
trasiiforms - tasiers ( suborder of haplorrhini)
noclutrnal- eyes bigger than brian
long trsus bone for jumping
playtyrrhini and catarhini shared characteristics
diurnal
reduced snout, dry nose, upper lip allows for a facial expressions
larger brain to body ratio
longer gestation, maturation and dependency
playtyrrhini traits
new world (american) monkeys flat, broad noses, outward facing nostrils 2:1:3:3 dental formation 2 families cebidae- eg. marmosets and tamarins alediae- spider, howler, wooley monkeys
catarrhini
old world monkeys, apes, humans narrow nose 2:1:2:3 dental formation sexual dimorhpism social organization two families - cercopithecodiem and hominioidea
cerocpithecoidea
cheek pouches, omniroves, egs. baboons, macaques, quenons
leaf eaters - asain languages, probpscos, colobus
homoinoidea
apes and humans prehensile hand and feet- grasping, 5 digits, tactile pafes, opposable thumbs, no tail > brain, colour, 3d vission > learning and behavioural felxability > social heneralized omniorves 2:1:2:3 dental formation
hylobatidea
‘lesser apes’
gibbons, and saigmahes
pongidae
‘greater apes’ organgtuans, chimps, baboons, gorillas
hoimindae
human
