Genetic erosion is defined as the loss of genetic diversity within a population or species. It can occur naturally through environmental changes or human activities such as habitat destruction, over-harvesting, and introduction of exotic species. Synonyms for genetic erosion include genetic homogenization, genetic depletion, genetic depopulation, genetic loss, genetic degradation, and genetic drift. These terms all refer to the same process of genetic diversity loss. Genetic erosion is a serious problem that can lead to decreased adaptation and resilience of a species to changing environmental conditions, which in turn can increase the likelihood of extinction. Conservation efforts are critical in protecting genetic diversity and its associated ecosystem services.
