Testing a New Passive Acoustic Recording Unit to Monitor Wolves
October 27, 2020
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

Testing Environmental DNA from Wolf Snow Tracks for Species, Sex, and Individual Identification
October 27, 2020
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

Territoriality drives preemptive habitat selection in recovering wolves: Implications for carnivore conservation
October 27, 2020
According to the ideal-free distribution (IFD), individuals within a population are free to select habitats that maximize their chances of success. Assuming knowledge of habitat quality, the IFD predicts that average fitness will be approximately equal among individuals and between … read more

Spatially varying density dependence drives a shifting mosaic of survival in a recovering apex predator (Canis lupus)
October 27, 2020
Understanding landscape patterns in mortality risk is crucial for promoting recovery of threatened and endangered species. Humans affect mortality risk in large carnivores such as wolves (Canis lupus), but spatiotemporally varying density dependence can significantly influence the landscape of survival. … read more

Spatial Responses of Wolves to Roads and Trails in Mountain Valleys
October 27, 2020
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
