Episode: CARTA - Humans: The Planet-Altering Apes - Loss of Species Loss of Genetic Variation and the Future of Earth’s Biota with Oliver Ryder
Description: We are experiencing an accelerated rate of loss of species due to human activities. This anthropogenic phenomenon extends beyond extinction. It encompasses an expanded loss of biodiversity as the genetic diversity of species diminish, reducing gene pools to “gene puddles.” We know details of species extinctions events from the fossil record, historical record, and from ancient DNA studies, and that historical processes shape extinction risk. Habitat loss and changing eco-environmental conditions, competition, and other factors produce genomic impacts, also influencing extinction risk. The legacy of past events impacts resiliency of species in the current environment in interpretable ways. Demographic trajectories reve...
