Expression and mechanisms of behavioral plasticity in large mammals Open
Behavioral plasticity, the alteration of behavior in response to stimuli, is becoming increasingly important in the context of human‐induced rapid environmental change. Theoretical and empirical studies suggest that the expression and magn…

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 (…

Infection–nutrition feedbacks: fat supports pathogen clearance but pathogens reduce fat in a wild mammal Open
Though far less obvious than direct effects (clinical disease or mortality), the indirect influences of pathogens are difficult to estimate but may hold fitness consequences. Here, we disentangle the directional relationships between infec…

Conserving habitat for migratory ungulates: How wide is a migration corridor? Open
Conserving migratory ungulates relies on the analysis of GPS collar data and associated maps of migration corridors to inform management and policy actions. Current methods for identifying migratory corridors use complex statistical models…

Migration Mapper: Identifying movement corridors and seasonal ranges for large mammal conservation Open
Modern tracking technology has facilitated a novel understanding of terrestrial mammal movement while revealing that movements are being truncated and lost. The first step towards conserving mobile animals is identifying movement corridors…

Heterogeneity in risk‐sensitive allocation of somatic reserves in a long‐lived mammal Open
Food quality and availability, when combined with energetic demands in seasonal environments, shape resource acquisition and allocation by animals and hold consequences for life‐history strategies. In long‐lived species with extensive mate…

View article: Behavior‐specific habitat models as a tool to inform ungulate restoration
Behavior‐specific habitat models as a tool to inform ungulate restoration Open
Across North America, many ungulate species that experienced historic population declines and range contractions are now broadly distributed across their native ranges after the implementation of successful restoration programs. The use of…
View article: Regional variability in pregnancy and survival rates of Rocky Mountain bighorn sheep
Regional variability in pregnancy and survival rates of Rocky Mountain bighorn sheep Open
In the Rocky Mountains, bighorn sheep restoration has been only marginally effective; this iconic wilderness species currently exists at a fraction of their historic abundance and often in fragmented and small populations. To inform bighor…

Restoration Potential of Bighorn Sheep in a Prairie Region Open
Efforts to recover Rocky Mountain bighorn sheep ( Ovis canadensis canadensis ) throughout western North America have had limited success with the majority of current populations remaining in small and isolated areas on a fraction of their …

Hiding Without Cover? Defining Elk Security in a Beetle‐Killed Forest Open
Recent mountain pine beetle ( Dendroctonus ponderosae ; pine beetle) outbreaks in the western United States have affected nearly 18 million ha of pine ( Pinus spp.) forest and are unprecedented in spatial extent, severity, and duration, ye…

Characterizing population and individual migration patterns among native and restored bighorn sheep (<i>Ovis canadensis</i>) Open
Migration evolved as a behavior to enhance fitness through exploiting spatially and temporally variable resources and avoiding predation or other threats. Globally, landscape alterations have resulted in declines to migratory populations a…

Spatial ecology of mountain ungulates in the northern Rocky Mountains: range expansion, habitat characteristics, niche overlap, and migratory diversity Open
Mountain ungulates, although recognized as iconic and charismatic wildlife species, are the least studied and understood large mammals in western North America. The paucity of data, specifically concerning spatial ecology, presents a formi…

Niche similarities among introduced and native mountain ungulates Open
The niche concept provides a strong foundation for theoretical and applied research among a broad range of disciplines. When two ecologically similar species are sympatric, theory predicts they will occupy distinct ecological niches to red…

The importance of fieldwork over predictive modeling in quantifying predation events of carnivores marked with GPS technology Open
Global positioning system (GPS) technology has revolutionized the study of carnivores. Researchers commonly estimate kill rates with GPS data using the following steps. Firstly, researchers mark individual animals and fit them with GPS col…

Seasonal resource selection by introduced mountain goats in the southwest Greater Yellowstone Area Open
Mountain goats ( Oreamnos americanus ) are among the least studied North American ungulates. Aided by successful translocations from the early to mid‐1900s, introduced populations have greatly expanded within non‐native ranges, yet there r…
