Impacts of Climite Changes in Animal Genetic Diversity

Abstract

Ecological changes taking place around the world will influence in living things and their environment in many ways. One of the most important factors is climate changes, threating not only to the existence of species, plants or animals but also to their genetic diversity. Genetic diversity is the variation in genomes of living things that is inheritable from generation to generation. Furthermore, it is a raw material for us to observe how species to adapt to their new environmental conditions against climatic fluctuations. A wide genetic variation in animal species is quite substantial for agriculture. Especially in livestock animal productions, populations that are composed of a wide variation refer to animals with inherent resistance to certain diseases or harsh environmental conditions in spite of yielding less economically important traits. Climate changes have certain effects in genetic diversity based on population size, gene flows and distributions among different geographical areas,and selection in terms of pressure, therefore should be under investigation how a species can be protected in the original habitat in order for mankind to maintain genetic variation.
