Intraspecific: died due to conflict with another wolf This has led some researchers to infer that wolves caused the decline.1,8,9 Wolves also can change the behavior of elk, causing them to move more and use habitat differently by seeking more cover.10-12 As in other parks, studies conclude that wolf predation can contribute to willow and aspen recovery, and overall habitat diversity, by reducing overbrowsing by elk, benefiting songbirds and beavers.1,8,10,11 Some studies also contend that willow and aspen recovery might change the flow of streams13-15, a topic that has gained considerable media attention.16 Other studies suggest that wolves can reduce coyote populations17 and thereby increase survival of pronghorn fawns upon which coyotes prey.18 Wolves also can benefit scavengers that feed on wolf kills such as bears, ravens, and eagles.6,19. Overall, such studies emphasize that understanding trophic cascades in large complicated ecosystems is challenging.3,4 Although loss of predators can cause ecosystem-level impacts2, reintroduction of carnivores, including wolves, doesnt always fully restore degraded ecosystems.23 In general, sweeping claims about trophic cascades caused by wolves are context-dependent and sometimes exaggerated.
