Mammalian predator co‐occurrence affected by prey and habitat more than competitor presence at multiple time scales Open
The behavior and abundance of sympatric predators can be affected by a complex dominance hierarchy. The strength of antagonistic interactions in predator communities is difficult to study and remains poorly understood for many predator ass…

Estimating ungulate migration corridors from sparse movement data Open
Many ungulates migrate between distinct summer and winter ranges, and identifying, mapping, and conserving these migration corridors have become a focus of local, regional, and global conservation efforts. Brownian bridge movement models (…

Warm places, warm years, and warm seasons increase parasitizing of moose by winter ticks Open
Observed links between parasites, such as ticks, and climate change have aroused concern for human health, wildlife population dynamics, and broader ecosystem effects. The one‐host life history of the winter tick ( Dermacentor albipictus )…

Wherever I may roam—Human activity alters movements of red deer (<i>Cervus elaphus</i>) and elk (<i>Cervus canadensis</i>) across two continents Open
Human activity and associated landscape modifications alter the movements of animals with consequences for populations and ecosystems worldwide. Species performing long‐distance movements are thought to be particularly sensitive to human i…

Diverse migratory portfolios drive inter‐annual switching behavior of elk across the Greater Yellowstone Ecosystem Open
A growing body of evidence shows that some ungulates alternate between migratory and nonmigratory behaviors over time. Yet it remains unclear whether such short‐term behavioral changes can help explain reported declines in ungulate migrati…

Wildlife migrations highlight importance of both private lands and protected areas in the Greater Yellowstone Ecosystem Open
Formally protected areas are an important component of wildlife conservation, but face limitations in their effectiveness for migratory species. Improved stewardship of working lands around protected areas is one solution for conservation …

A statistical framework for modelling migration corridors Open
Management of animal populations requires spatially explicit knowledge of movement corridors, such as those used during seasonal migrations. Global Positioning System (GPS) tracking data allow for mapping of corridors from directly observe…

Estimating wolf abundance from cameras Open
Monitoring the abundance of rare carnivores is a daunting task for wildlife biologists. Many carnivore populations persist at relatively low densities, public interest is high, and the need for population estimates is great. Recent advance…

Predicting fine-scale forage distribution to inform ungulate nutrition Open
The quantity and nutritional quality of forage are key drivers for ungulate populations, including mule deer (Odocoileus hemionus) and Rocky Mountain elk (Cervus elaphus nelsoni), in the western U.S., but current vegetation maps are too co…

Competition for safe real estate, not food, drives density‐dependent juvenile survival in a large herbivore Open
Density‐dependent competition for food reduces vital rates, with juvenile survival often the first to decline. A clear prediction of food‐based, density‐dependent competition for large herbivores is decreasing juvenile survival with increa…

Linking forest management to moose population trends: The role of the nutritional landscape Open
Forested lands in the western USA have undergone changes in management and condition that are resulting in a shift towards climax vegetation. These changes can influence the quality and quantity of forage for herbivores that rely on early-…
