Now is a crucial time to explore the potential implications of this information revolution for conservation genetics and to recognize limitations in applying genomic tools to conservation issues.

FW ALLENDORF, G LUIKART, SN AITKEN. Wiley-Blackwell, 2013. Over the past twenty years conservation genetics has progressed from being mainly a theory-based field of population biology to a full-grown empirical discipline. Technological developments in molecular genetics have led to extensive use of neutral molecular markers such as microsatellites in conservation biology.

Abstract: Genetic diversity is one of three levels of biological diversity requiring conservation. Abstract Population differentiation is a fundamental process of evolution, and many evolutionary studies, such as population genetics, phylogeography and conservation biology, all require the inference of population differentiation. Recently, there has been a lot of debate over the validity of FST (and its analogue GST) as a. programme should use animals from different parts of the species' present distribution area.

For instance, understanding which elephant populations are more studied can direct efforts to less-studied populations and result in an improved understanding of the genetic variability.
