George Schaller (1963)
- primate and field ecology research | - mountain gorilla
26
percent of leaves in diet - graph
- x axis: body weight - y axis: percent of leaves in diet - galago-->tamarin-->macaque-->chimp-->gorilla
27
adaptations for vegetarianism - sportive lemur - langur/howler - colobus - gorilla
- sportive lemur: copophagia - langur/howler: elongated intestine - colobus: sacculated stomach - gorilla: long digestive tract
28
plant adaptations to limit consumption - new leaves? - sunlight? - monkey examples (5)
- chemicals that must be tolerated by monkeys - new leaves have more difficult to digest chemicals - sunlight can increase chemicals - howler monkey: can eat new leaves, red leaves and sun leaves - bamboo and gentle lemur - aye aye - coconuts and bark - tarsier can spin head 180 degrees - chimps and self-medication
29
extreme example of monkey adaptations to plant chemicals
- bamboo and gentle lemur - bamboo-cyanide - gentle lemur is a bamboo specialist; should be dead based on amount it consumes - 500 mg; 12x lethal dose
30
chimpanzees and self-medication
-eat certain plants to get rid of parasites
31
finding food in large groups
-food is predictable, clumped and abundant
32
finding food in small groups/solitarily
-food is unpredictable dispersed and sparse
33
K strategists
- primates have less offspring - want them to survive - stable and predictable - slow development - high offspring investment * *Larger primates
34
R strategists
- choose to adapt to world by having lots of children - high infant mortality - variable, unpredictable - low offspring investment * *marmosets and tamarins kind of
35
seasonal breeding
- common in monkeys | - births oriented to wet season when there is more food
36
carrying capacity
- fewer speices in fragmented forest compared to undisturbed forest - decreases with disturbance - south america blackwater forest
37
South American Blackwater forest
- low carrying capacity because of nutrient runoff into the water - the white water forests have a higher carrying capacity
38
What percent of monkey's diet is composed of leaves?
- 20% | - need special adaptations to eat more than that
39
different types of frugivores - good and bad things about them
- speed predators: reduce overabundance; destroy seeds | - seed dispersers: helpful to trees; don't get digested
40
extreme environments
- dry grassland - high altitude - harsh habitat - urban environment - ocean - rivers
41
monkeys that live in dry grassland + characteristics
- gelada baboon - forage grass and seeds during the day - sleep on rocks at night
42
monkeys that live in high altitude with snow and high seasonality
- japanese snow monkey | - golden monkeys in China - eat pinecones
43
monkeys that live in harsh habitats
- Sifaka - very sharp terrain; dry - tsingy nature reserve in northern madagascar
44
monkeys that live in urban environments
-India - live on the streets
45
monkey that lives in/near the ocean
-crab-eating macaque
46
monkey that lives in/near river
-proboscis monkey
47
squirrel monkey example about carrying capacity
- squirrel monkey dealer put too many monkeys on an island - number of squirrel monkeys decreased when it was expected to increase - carrying capacity was not big enough
48
what time of year do lemurs give birth during
-November to January
49
Sympatric Species vs Allopatric Speices
- sympatric: organisms evolve from the same ancestor into different species in the same location - allopatric: organisms evolve from similar ancestors into different species in different locations
50
example of sympatric species living together - number of speices studied - location - name of researcher - adaptations - type of distribution; food
- case study of 8 species in Suriname - tamarin, squirrel monkey - spider monkey - howler monkey - 2 species of saki - 2 species of capuchin - Russ Mittermier; Raleighvallen Voltzberg - vertical and horizontal distribution; not directly competing - bigger primates are higher up and smaller primates are lower down - different food specializations - squirrel monkeys (understory-bugs), bigger monkeys (leaves)
51
predatory-prey study - African Savannah - main predators - total kills - findings?
- looked at total number of kills (46,0000) - 75 baboons killed - main prey: fossa, striped civet, yellow-billed kite, ground boa - other predators: leopards, lions, hyenas, crocodiles, python - baboons are not the primary food source - successful
52
Birds of prey in Guyana
- good predators - killed 47 monkeys of 141 kills - 1 cebid monkey per month
53
Ecuadorian hunter/gatherer tribe
- 3 year time period - 562 wooly monkeys, 246 howler - eat them
54
Chimpanzees as predators - what do they eat? - what increases success?
- eat red colobus monkeys | - number of hunters in the part increases percent success
55
anti-predator defenses
- cryptic hiding - leaping locomotion - large groups - multi-male groups - communication and social strategies - higher reproductive rate to overcome mortality
56
Parasite Avoidance in baboons - person who observed it - location - parasite name - mechanism
- Glenn Hausfater - Amboseli - avoided life cycle of intestinal parasite called strongyloides - parasite takes 2-3 days to hatch and is infectious for 4.5 days; neutralized by sun and removal by dung beetles - baboons move away and come back in about 9 days when threat of parasite is gone
57
parasite avoidance in capuchins
- high percent of monkeys carry parasites | - groom each other to remove ticks and check for parasites
58
GI parasites in Howler monkeys - study - study question - researcher - findings
- are parasites worse in disturbed forest than undisturbed forest? - collected fecal matter and looked for parasites - found that parasite load is higher in disturbed forest
59
Microbial exchange across species - researcher - monkeys studies
- Tony Goldberg - looked at fecal matter and realized that there is an exchange of bacteria between humans and animals - studied BW colobus, red colobus, red-tailed Guenon
60
Herpes saimari - who is affected? - how is it transmitted? - who is NOT affected?
- latent virus in squirrel monkeys or capuchins - vertical transmission (mother-->offspring) - infectious and lethal to tamarins and marmosets, spider monkeys and owl monkeys (causes leukemia) - this type also doesn't affect humans - possible germ warfare??
61
How primates deal with complex environments
- limit land use | - activity during many parts of the day (cathemeral - diurnal and nocturnal)
62
capuchin vs. chimpanzee - foraging times | -what do they have in common?
- chimps: rainy season - capuchin: dry season - both opportunistic omnivores
