Document Summary
The loss of biodiversity is the most important process of environmental change. This is because it is the only process that is wholly irreversible. Its consequences are also the least predictable, because the value of the earth"s biota is largely unstudied and unappreciated. The number and kinds of living organisms in a given area. Our focus intraspecific variation or genetic diversity. Applying genetic methods to conservation, restoration, and endangered species management. Focuses on all 3 levels of genetic diversity. Different solutions will address loss of genetic diversity at each of the 3 levels. 3 variation may lead to different solutions, so we need to construct different goals. When in a population:some are red, some are blue. Random sampling of allele will increase in small populations. Loss of genetic variation as alleles fix randomly. As a consequence, there will be a loss in genetic variation. Inbreeding depression from exposure of rare, recessive allele.
