Wolf social group dynamics matter for infectious disease spread, models suggest

By modeling wolves in Yellowstone National Park, researchers have discovered that how a population is organized into social groups affects the spread of infectious diseases within the population. The findings may be applicable to any social species and could be useful in the protection of endangered species that suffer from disease invasion. Like other social carnivores, wolves tend to form territorial social groups that are often aggressive toward each other and may lead to fatalities. During these encounters, infectious diseases like mange and canine distemper can spread between groups, which can further reduce the number of individuals in a group.

Mange in Yellowstone wolves reveals insights into human scabies and conservation biology

Mange in Yellowstone wolves reveals insights into human scabies and conservation biology Liana Wait, Department of Ecology and Evolutionary Biology Jan. 25, 2021 9:30 a.m. Before wolves were reintroduced to Yellowstone National Park in the mid-1990s, they were vaccinated for common diseases and treated for any parasite infections they already carried. As a result, the first few generations of wolves were relatively disease-free, but over the years, various diseases have found their way into the population.  Both of these Yellowstone wolves display the hair loss and skin lesions associated with mange. By analyzing 25 years of wolf observations and genetic samples from 408 Yellowstone wolves, a Princeton-led research team found that genetics play a role in the severity of the mite-borne disease. They found support for the monoculture theory : wolves with severe mange, like the one on the left, tend to have less genetic variation than wolves with mild symptoms, as

Wolves now seen as control on CWD, but not in Pennsylvania

Outdoornews January 19, 2021 There is a way to slow the spread and perhaps eliminate the scourge of chronic wasting disease in Pennsylvania deer, and you heard it here first – stock wolves. Nah, just kidding. Obviously, introducing those relentless predators into Pennsylvania’s mostly crowded, mixed urban-rural landscape would be irresponsible, wrong headed and disastrous. But it is worth noting that those wild canines are now seen by some as a control on the always-fatal-to-deer disease in other parts of the country. A study is underway in Yellowstone National Park to see if wolves can control CWD, and interestingly, there is a Pennsylvania connection to the work. Researchers are studying the effects of when a predator sustains the health of a prey population by killing the sickest animals

'Zombie' deer disease spreads in US but wolves may offer solution

Chronic wasting disease is a fatal illness similar to mad cow disease and cases have been reported in deer and elk in at least 24 American states.

Wolves may save humans from 'zombie' deer disease spreading across US
