In Yellowstone’s predator hierarchy, cougars must navigate competition with wolves & bears. A new study from the team finds prey size influences predation patterns, food theft & shapes coexistence in unexpected ways. Check it out! https://t.co/BKi0XPEXfr

The president of The Wildlife Society and 23 past presidents are calling for Wyoming to address wildlife abuse. They wrote a letter to the governor in response to the recent harming and frivolous killing of a wolf in the state.

New paper out on genetic structure and effective population sizes of gray wolves across parts of North America. Important implications for wolf conservation by recognizing long term viability of wolf populations relies on more than total census sizes. https://t.co/EvO8pfw3h0

This spring, Yellowstone biologists documented adult wolves from the Mollie’s Pack traveling back to their den with some interesting items. https://t.co/AAMjoqL3c9

Very happy that our paper is out on ravens' use of anthropogenic subsidies around Yellowstone National Park - based on Cameron Ho's undergrad. thesis, who did an amazing job! with @drstahler @safilabmpi @martinwikelski et al. https://t.co/SupkomRpuo 🧵 (1/6)

Check out our new paper in @JAppliedEcology. Land use change is increasing, but what thresholds of human development/agriculture lead to wildlife avoidance, and how do these responses vary based on level of selection? https://t.co/Me0QFOScJL

The first chapter of my dissertation is now published Open Access in @Ecology_Letters! We found that density-dependent habitat selection alters the food-safety tradeoff, with implications for community interactions. https://t.co/9nrUEPff5i

Relatively little is known about how density dependence affects variation in population distribution. We found that density-dependent habitat selection changes the relative drivers of elk distribut...

Animal behavior and decision-making are complex processes influenced by many factors: past experience, genetics, current circumstances, group mates or family members, and now we can add the parasite, Toxoplasma gondii, to that list for gray wolves. https://t.co/zKT7MTJsih

Why do half of @YellowstoneNPS wolves have black coats? Blame it on a virus similar to the measles, researchers have discovered. @DanMacnulty @SarahCubaynes #YellowstoneWolfProject. https://t.co/8kkHuywB9p

Excited to share a new paper from my postdoc research: protected areas are an important component of wildlife conservation, but private lands are also important for the conservation/management of migratory/wide-ranging wildlife such as elk. https://t.co/83dhXjyexH

Important new article from @LauraCGig et al. explains why the future of migratory elk populations in the Greater Yellowstone Ecosystem depends on the conservation of private lands outside of Yellowstone National Park and other protected areas. https://t.co/VcsyBnL05q

#YellowstoneNP carnivores such as #cougars, #bears, and #wolves compete for food resources. This map, using data collected by the Yellowstone Cougar Project, tells the story of Cougar F207 who killed three elk over 7 days due to bears displacing her from her kills. 🐆🐻🐺
