BIOLOGY 321 Lecture Notes - Lecture 4: Cheirogaleidae, Simian, Hamadryas Baboon
Document Summary
Prosimii vs anthropoidea: strepsirrhines and (wet nose) are alternative naming system that causes a change in groups for one group. Distribution of living (non-human) primates: generally equatorial, due to inability to survive in northern winters or deserts. Prosimian distribution: cheirogaleidae, lemuridae, indriidae, and daubentoniidae are restricted to madagascar. All of these are endangered, but account for about 26% of primate diversity: lorisidae (lorises tend to be fast moving) are restricted to southeast asia and ssa the other family (tar something) became nocturnal. Cebidae and callitrichidae: known for their uniformity, all are arborial: see slides for distribution of different families. Habitats: generally founding in tropical or monsoon rainforest, swamp mangroves, gallery forests, and savannah. Few live in grasslands, baboons included, but are very territorial. The niche characterizes every member of the species that belongs to that species. Nocturnal: pros: decreased heat stress, predation, enhanced smell, cons: reduced foraging ability and social communication.
