During a recent review of the U.S. Fish and Wildlife Service’s recovery plans for more than 200 endangered and threatened vertebrate species in the United States, Michigan State University researchers made an interesting discovery. They found that two-thirds of these species could benefit from a gene-boosting diversity strategy known as genetic rescue, yet only three of these plans to support species recovery currently use this approach. In a study recently published in the Journal of Heredity, MSU integrative biologist Sarah Fitzpatrick and postdoctoral researcher Cinnamon Mittan-Moreau found that more than two-thirds of the 222 species they evaluated would be good candidates for consideration of genetic rescue.
