Document Summary

Metapopulations - group of populations connected with migration. Having lots of little habitats is a xguard against extinction. Human activity -> habitat fragmentation -> increase frequency of meta-population structure. Goal: maintain even small patches, as these are sources for future colonization. Population ecology concepts - needed to manage species. Ex: life-table data: which aspects of life history are most sensitive for particular species. Reduce loss of adult females to fishing nets (more valuable commodities) Absence of density-dependent regulation -> sustained exponential growth -> population crash. Human activity -> habitat fragmentation -> meta population structure. Conservation: understand life history, population dynamics, and more (interspecific interactions, climate ) Don"t need to study box 54. 3, but read to end of section. Dexterous hands, feet; partially or fully opposable thumbs/ big toes. Large brains (proportioned to body size), complex social behavior. Low fecundity (giving birth to mostly single births) Hominids = great apes = chimps, gorillas, orangutan, human.
