Effect of harvesting on the genetic diversity and dynamic behavior of a limited mendelian population

Effect of harvesting on the genetic diversity and dynamic behavior of a limited mendelian population A mathematical model of the changes in the size and genetic diversity of a harvested, single-locus Mendelian population under the conditions of density-dependent selection is analyzed, with a special emphasis on the possibility of conserving or loosing polymorphism as a result of equilibrium harvesting. It is demonstrated that harvesting leads to changes in intrapopulation parameters under the conditions of density-dependent selection; as a result, the genotypes that were the least fit in an unharvested population will prove more fit, the genetic composition of the population at equilibrium being changed accordingly. Thus, harvesting may, under different conditions, either conserve or reduce the genetic diversity of the population. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

A mathematical model of the changes in the size and genetic diversity of a harvested, single-locus Mendelian population under the conditions of density-dependent selection is analyzed, with a special emphasis on the possibility of conserving or loosing polymorphism as a result of equilibrium harvesting. It is demonstrated that harvesting leads to changes in intrapopulation parameters under the conditions of density-dependent selection; as a result, the genotypes that were the least fit in an unharvested population will prove more fit, the genetic composition of the population at equilibrium being changed accordingly. Thus, harvesting may, under different conditions, either conserve or reduce the genetic diversity of the population.
