Welcome back to Season 4 of I Came For Science. In this episode, Laura interviews Dr. Meg Martin about her research on conservation breeding. Conservation breeding is a method of increasing the populations of endangered and threatened species by having them breed in captivity and then releasing the resulting offspring into the wild when they are old enough. Traditionally, breeding pairs were chosen to maximize the genetic diversity of the population. However, until relatively recently, the important role of mate choice was not considered. Dr. Martin's work has changed this approach to use the science of sex to improve reproductive outcomes.
