Document Summary
One of the biggest concern regarding ex-situ is that they remain representative of their taxa. Pg87 pdf:4 variables under management control for animals in captivity. Domestication generally acts through a process of intentional artificial. 2 types of adaption are relevant for captive breeding: non-heritable adaption to captive conditions, genetic adaptation to captivity. Non-heritable adaption: those that show plasticity can morphologically, physiologicall, or behaviourally adapt to their env. Genetic adaptation to captivity: ie marsupials captive bred individuals had longer tails and snouts than wild ones, and differed in their ability to enter torpor. They are not normally under selection: this neutrality is essential for captive breeding because, the management of captive pop by minimising mean kinship, modelling retention of genetic diversity in captive breeding programmes assume neutrality. Genetic changes vary in terms of effects and regarding time scale (slow to fast) Despite rise in fitness, adaptation to capitivity may impede animals from surviving in the wild upon release.
