Logging, linear features, and human infrastructure shape the spatial dynamics of wolf predation on an ungulate neonate
November 29, 2023
Humans are increasingly recognized as important players in predator–prey dynamics by modifying landscapes. This trend has been well-documented for large mammal communities in North American boreal forests: logging creates early seral forests that benefit ungulates such as white-tailed deer (Odocoileus … read more

Video observations of wolves hunting ungulates on linear features
June 30, 2023
Anthropogenic linear features allow wolves to travel faster and more efficiently, which is thought to increase wolf hunting efficiency of ungulates. Most previous studies have evaluated the role of linear features in wolf-ungulate dynamics by relying on indirect observations (e.g., … read more

The ethology of wolves foraging on freshwater fish in a boreal ecosystem
June 3, 2023
Through global positioning system (GPS) collar locations, remote cameras, field observations and the first wild wolf to be GPScollared with a camera collar, we describe when, where and how wolves fish in a freshwater ecosystem. From 2017 to 2021, we … read more

Group composition effects on aggressive interpack interactions of gray wolves in Yellowstone National Park
November 30, 2022
Knowledge of characteristics that promote group success during intraspecific encounters is key to understanding the adaptive advantages of sociality for many group-living species. In addition, some individuals in a group may be more likely than others to influence intergroup conflicts, … read more

Metabarcoding of fecal DNA shows dietary diversification in wolves substitutes for ungulates in an island archipelago
November 2, 2022
Although ungulates are the main prey of wolves (Canis lupus) throughout their range, substantial dietary diversity may allow wolves to persist even when ungulates are declining or rare. Alexander Archipelago wolves (Canis lupus ligoni) inhabit distinct mainland and island biogeographic … read more

Extinguishing a Learned Response in a Free-ranging Gray Wolf (Canis lupus)
April 2, 2022
A free-ranging Gray Wolf (Canis lupus), habituated to human presence (the author) on Ellesmere Island, Canada, learned to anticipate experimental feeding by a human, became impatient, persistent, and bold and exhibited stalking behaviour toward the food source. Only after the … read more
