Site summary
- Wolf-on-wolf conflict accounted for about two-thirds of known natural mortality among Yellowstone National Park collared wolves (1995–2015; Figure 1).
- The authors report that, in the observed Yellowstone inter-pack conflicts, the presence of older wolves was a better indicator of success than total pack size.
