Wolves choose ambushing locations to counter and capitalize on the sensory abilities of their prey
TLDR
The work describes in detail the ambush strategies wolves use to hunt beavers and continues to overturn the traditional notion that wolves rely solely on cursorial hunting strategies, demonstrating that ambush predators can anticipate the movements and behavior of their prey due to a fundamental understanding of their targets’ sensory abilities.
Cross‐continental comparison of parasite communities in a wide‐ranging carnivore suggests associations with prey diversity and host density
TLDR
The result that fecal prevalence of parasites was lower in wolves with more diverse diets could provide insight into the mechanisms by which biodiversity may regulate disease, as well as regulate the effects of parasitism on prey populations.
Indirect Effect of African Swine Fever on the Diet Composition of the Gray Wolf Canis lupus—A Case Study in Belarus
TLDR
Only intensive hunting of wolves by humans can explain the resulting dietary fluctuations between elk and beaver, as well as the fact that wolves did not turn to other food sources.
Trumpeter Swan Killed by Gray Wolf in Minnesota
Abstract Canis lupus (Gray Wolf) have been suspected as natural predators of Cygnus buccinator (Trumpeter Swan), but detailed descriptions of such predation events are lacking from the peer-reviewed
Outsized effect of predation: Wolves alter wetland creation and recolonization by killing ecosystem engineers
TLDR
This study demonstrates how predators have an outsized effect on ecosystems when they kill ecosystem engineers by killing dispersing beavers.

Seasonal foraging strategies of Alaskan gray wolves (Canis lupus) in a salmon subsidized ecosystem
TLDR
The authors' results demonstrate substantial variability in the use of salmon over time in gray wolf diets in Lake Clark National Park and Preserve in southwestern Alaska, with one group of wolves consistently consumed salmon in summer and switched to terrestrial prey in winter.
Exploitation of marine resources by wolves in southwestern Alaska
Predation by large carnivores is a dominant factor shaping wildlife communities and an understanding of local foraging strategies of predators is central to the management of wildlife populations.
Weekly Summer Diet of Gray Wolves (Canis lupus) in Northeastern Minnesota
TLDR
This work is the first to examine wolf diet via scat analysis at weekly intervals, which enabled it to provide a detailed description of diet plasticity of this wolf pack, as well as the rapidity with which wolves can respond to new available food sources.
Foraging Behaviours and Diets of Wolves in the Queen Maud Gulf Bird Sanctuary, Nunavut, Canada
Predation patterns often reflect the abundance and distribution of prey although factors such as vulnerability and ease of prey capture also affect these patterns. Wolves ( Canis lupus ) rely
Food Habits of Wolves in Relation to Livestock Depredations in Northwestern Minnesota
TLDR
A 3-y study examining the food habits of wolves in an agricultural area of northwestern Minnesota and their relation to depredation records of livestock losses in the same area found that wolves in the area preyed mostly on native prey species.
Food habits of the world's grey wolves
TLDR
No evidence is found that grey wolf dietary diversity varies globally, although the results from southern Europe suggest that grey wolves may switch their diets away from domestic species if more wild ungulates are available, and the diversity of prey consumed by grey wolves shows that the species is capable of surviving dramatic anthropogenic upheaval.
Where and How Wolves (Canis lupus) Kill Beavers (Castor canadensis)
TLDR
By identifying kill sites and inferring hunting behavior, this work has provided the most complete description available of how and where wolves hunt and kill beavers in boreal ecosystems.
Problems with studying wolf predation on small prey in summer via global positioning system collars
TLDR
It is found that a male and female wolf with global positioning system (GPS) collars programmed to acquire locations every 10 min in the Superior National Forest of Minnesota missed finding many prey items and discusses the problems associated with trying to conduct such a study.
Gray Wolf ( Canis lupus ) dyad monthly association rates by demographic group.
Preliminary data from GPS-collared wolves (Canis lupus) in the Superior National Forest of northeastern Minnesota indicated wolves had low association rates with packmates during summer. However,
