If applied generally to other species, the 2019 rule’s approach to ESA implementation would represent a significant scaling back of recovery efforts for widely distributed species that would increase both short term vulnerability and long-term loss of adaptive potential. Recent … read more

Caribou and reindeer Rangifer tarandus are declining across North America and Scandinavia in part from wolf Canis lupus-mediated apparent competition with more abundant ungulate prey species. While caribou generally persist in areas with low wolf density, wolf packs that overlap … read more

Wolves’ attacks on hunting dogs are a major conflict between wolves and hunters in Northern Europe. The reasons affecting the risk of wolves’ (Canis lupus) attacks on hunting dogs are poorly known. We examined whether the number of wolves in … read more

As part of a broader trial of noninvasive methods to research wild wolves (Canis lupus) in Minnesota, USA, we explored whether wolves could be remotely monitored using a new, inexpensive, remotely deployable, noninvasive, passive acoustic recording device, the AudioMoth. We … read more

Monitoring elusive, relatively low-density, large predators, such as the grey wolf (Canis lupus), has often been accomplished by live-capture and radiocollaring. Increasingly, non-invasive methods are considered best practice whenever it is possible to use them. Recently, environmental DNA (eDNA) deposited … read more

Increasing levels of human activity in mountainous areas have high potential to inhibit animal movement across and among valleys. We examined how wolves respond to roads, trails, and other developments. We recorded the movements of two wolf packs for two … read more
