Term
|
Definition
| Evolutionary process by which a single ancestor gives rise to multiple descendent lineages each of which occupies a separate niche. |
|
|
Term
|
Definition
Eats gum and sap (exudates)
Chisel like incisors and enlarged cecum
Callimico, Callithrax,Cebuella, Calibella, Mico |
|
|
Term
|
Definition
Eats fruit, fungus, nectar, insects
Large homerange
Lower population density |
|
|
Term
| Polyspecific Associations |
|
Definition
Animals modify behavior due to the presence of another species.
Costs: competition, mitigate by differential foraging techniques and use of vertical dimensios of the forest.
Benefits: Increased foraging efficiency, protection from predators, shared resource defense. |

Feeding Ecology
Of
Pithecines |
|
Definition
Titi- Fleshy fruits and leaves, insects supplement diet, some species are seed dispersers
Sakis and Uakaris- Seeds are 1/3 to 2/3 of diet, high lipid content, buffer against seasonal fruit shortages, inhabit areas with poor nutrient soils where trees invested heavily in high quality seed production |
|
|
Term
|
Definition
| Quadrupeds, short bushy tail, bald heads, bright face, large multimale groups and large homeranges, very little info on social organization, hunting these monkeys cause decline in population in certain areas (Peru) |
|
|
Term
|
Definition
Least extreme in their dental adaptions
Smaller body size
Mostly monogamous, pair bonded, tail twining, possibly territorial, high level of paternal care
Species Specific: body size, pelage, chromosome |
|

Term
Reproduction and Mating
of
Cebinae |
|
Definition
Capuchins: yearly birth peak, slow to mature, very long lived, slow post natal brain growth and motor skill development, eleborate courtship, dominance depends on mating success in males.
Squirrel Monkeys: Strict seasonal breeding, males gain water weight for breeding season. (fatted males)
Fattest males preferred by females. |
|
|
Term
| Feeding Ecology of Cebinae |
|
Definition
Capuchins: dextrous hands, extractive foraging, some tool use.
Squirrel: Less wide ranging habitats, prefer tropical lowland rain forests, more insectivores, may spend 8-% of time foraging. (polyspecific associations with capuchins) |

|
|
Term
|
Definition
| Strong sexual dichromatism, long bushy tails, leaping locomotion in understory, group size smaller depending on population density, food distribution and larger pithecines, some pair bonding, monogamous, small home range, possibly territorial |
|
|
Term
|
Definition
| Larger body size, above branch quadrupeds, long bushy tails, large ulti male groups and large hoe range, very little info on sociail organization. |
|
|
Term
| Cebinae dispersal patterns |
|
Definition
Capuchins- Female philopatric (uncommon in NWM), Males disperse pattern of parallel dispersal may explain cooperative males
Squirrel- geographic patterning to dispersal patterns, ecology depends on food availability
(m and f philopatry, all sexes disperse) |

Definition
Owl Monkey
Night Monkey
Douroucoulis
(nocturnal, monogamous) |
|
|
Term
| Dispersal Pattern of Aotines |
|
Definition
sexes disperse
Dispersal time may be linked to birth season
evidence for delayed dispersal
solitary for a while after leaving native group |
|
|
Term
| Feeding Ecology of Aotines |
|
Definition
Frugivores (especially figs)
More leaf eating in cathemeral and crepescular (or with more moonlight)
Insect eating observed but not quantified |
|
|
Term
| Aotines social groups and home ranges |
|
Definition
Group size: 2-6
Solitary animal of both sexes also observed (young emigrants transferring, old evicted individuals)
Territorial because of food resources and mating opportunities. |
|
|
Term
| Aotines Mating and reproduction |
|
Definition
Monogamous
One birthper years (first birth at age 2.5-5)
Excessive male caretaking
(increased offspring survival, increased female foraging time, mating effort)
Shorter interbirth intervals w/ increased length of pair bond. |
