Essay / Genetic Diversity on Restoration of Endangered Species
Genetic Diversity on RestorationThe compilation of all direct and indirect effects on the planet by human activities has become very critical for the restoration of endangered species to their native environment. Efforts are being made around the world to prevent many species from disappearing from the face of the Earth. In areas where species or population fitness is low, a conservation management strategy has been advocated to avoid extinction. Such a case can be seen with the Florida Panthers, in which unrelated species from another population were introduced into the population to reestablish the population. Determining what is needed to accommodate the restoration is only the first step. The goal is to restore its function to where it previously thrived. The two current issues are the accuracy or authenticity of a restoration project and its functionality (Suding 2011). A reintroduction project is genetically accurate if it restores the original gene pool of the population it is replacing. If the original population has disappeared, precision is impossible because alleles unique to that particular population are lost. The restore may be accurate and perform poorly or it may be inaccurate and perform poorly. Reintroduction does not result in a perfectly precise gene, so the question we need to ask is “How close enough is it?” » There is no definitive answer because not all variations have adaptive significance. Furthermore, variation between populations is a continuous variable since two populations can vary by one or more alleles. If the motivation is an ethical commitment to fidelity to the historical distribution of genotypes, the line can be drawn anywhere. Best practice is to estimate and report the degree...... middle of article ......19(2): 166-176.Kay KM, Sargent RD 2009.
