4/1/2023 0 Comments Wolf coyote“We want to avoid inbreeding, but there’s a finite number of animals.” “The captive red wolf program struggles with a highly related population,” she said. “Coyotes are not an endangered species, but now if we suspect they’re carrying a lot of endangered genetics as a legacy, that could be useful to preserve red wolves,” vonHoldt added.īecause the population of red wolves is so small, they have faced a genetic bottleneck, vonHoldt told CNN. “We have to work on what our definition is, where we draw those lines – it’s not easy,” she said. “We would probably benefit from protecting that animal.” Shuttīut “if an animal truly does carry 70% of the genes of an endangered animal, it’s an endangered animal,” she continued. Kristin Brzeski prepare to collar and process a Louisiana coastal coyote for their study that is explores the red wolf ancestry found in this special group of canids. “Most people will likely ask: If something has 70% red wolf genetics, is that a red wolf?” said vonHoldt. Decades of interbreeding have made it difficult to delineate clearly between the two species, as vonHoldt’s genetic analysis of the southwestern Louisiana coyotes demonstrates. Coyotes, far from being endangered, are abundant throughout many parts of North America and are legal to hunt in the United States. The discovery raises significant questions for conservation policy. The “range of red wolf ancestry is anywhere from 30 to 70%,” vonHoldt said. The team took samples from around 30 coyotes in Louisiana and analyzed their genetics for similarity to red wolves. The research focuses on a population of coyotes in southwestern Louisiana, close to where the last surviving red wolves were identified and moved into captivity in the 1970s.

These “ghost genes” might play a crucial role in preserving the red wolf population.įirst-time red wolf mother May tends to her newborn pup at the Roger Williams Park Zoo. “Even though the red wolves went extinct, or so we’re told, those genes likely survived in these coyotes that carry that legacy with them,” explained Vonholdt to CNN. Genetic research published in Science Advances by vonHoldt and her team on June 29 found that many of those coyotes had significant red wolf ancestry, a result of interbreeding between red wolves and coyotes. Today, thanks to the work of conservationists, there are around 20 red wolves in the wild in North Carolina, re-released from the captive populations, and 240 in American zoos and sanctuaries.īridgett vonHoldt, a biologist at Princeton University, had heard stories from observers in Texas and Louisiana who noticed that the coyotes in their areas were “different” – larger and more visually similar to red wolves than a typical coyote. Red wolves once lived throughout the southeastern United States but were declared extinct in the wild in 1980. While coyote and wolf attacks on humans are rare, you wouldn’t want to be in this stat.Scientists are hopeful that the key to reviving red wolves, which are on the brink of extinction, may lie in the genes of coyotes that have significant red wolf ancestry. Watch this video from the Business Insider to learn exactly what to do if you encounter a coyote in the neighborhood or in the wild: Always hike and camp in a group - never alone! Keep any dogs you may have with you on a leash.
