Abstract
In the current global health climate, many conservation biologists are managing crisis situations, including increased species extinction rates. One strategy for securing wildlife populations into the future is to preserve biomaterials in genome resource banks (GRB; or ‘biobanks’). However, for GRBs to be successful we must understand the fundamental reproductive biology of species, along with developing assisted reproductive techniques (ARTs), including AI and semen cryopreservation. ART has been successfully used for several taxa, from amphibians to mammals, including ungulates, carnivores and primates. Not all these success stories implemented the use of a biobank, but one example that discussed herein is the black-footed ferret (Mustela nigripes) GRB. From a founder population of seven individuals, this species has been breeding in a managed setting for nearly 30 years. The goal of the breeding program is to maintain genetic integrity by ensuring each individual has the opportunity to pass his/her genes onto the next generation, while simultaneously providing animals for release into the wild. Scientists have used ART (e.g. AI) in the recovery program. Recently, semen from an individual of the founder population that was cryopreserved for up to 20 years was used successfully for AI, which improved the genetic diversity of the population. The black-footed ferret recovery program can serve as a model for other endangered species and demonstrates the usefulness of ART and GRBs to maintain highly endangered species into the future.
