Desert bighorn sheep in the Mojave National Preserve in California and surrounding areas appear to be more resilient than previously thought to a respiratory disease that killed dozens of them and sickened many more in 2013, a new study has found. Clint Epps, a wildlife biologist at Oregon State University, and several co-authors, found that exposure to one of the bacteria associated with the disease is more widespread among bighorn sheep populations in the Mojave, and that its presence dates further back, than scientists thought. Epps, who began studying desert bighorn sheep in 1999, said they are a species that brings people together. [Extracted from the article] |
