Wolverine occupancy, spatial distribution, and monitoring design
In the western United States, wolverines (Gulo gulo) typically occupy high-elevation habitats. Because wolverine populations occur in vast, remote areas across multiple states, biologists have an imperfect understanding of this species' current…
Wolf prey selection in an elk-bison system: choice or circumstance?
What a predator eats when given choices, and the subsequent effects of this behavior on ecosystem stability, has long been a topic of interest for ecologists. Prey selection is influenced by the absolute and relative abundances of prey types, the…
Wolf kill rates: predictably variable?
The ability of predators to successfully capture and kill prey is affected by the abundance and diversity of the prey assemblage, and such variation is a fundamental driver of ecosystem dynamics because per capita consumption rate strongly influences…
Winter recreation and Canada lynx: reducing conflict through niche partitioning
Outdoor recreationists are important advocates for wildlife on public lands. However, balancing potential impacts associated with increased human disturbance with the conservation of sensitive species is a central issue facing ecologists and land…
Winter diet and hunting success of Canada lynx in Colorado
Information regarding the diet of Canada lynx (Lynx canadensis) at the southernmost extent of its range is critical for managing the species under current and predicted climate conditions. Therefore, from 1999–2009, we investigated winter diet and…
Wild felids as hosts for human plague, Western United States
Plague seroprevalence was estimated in populations of pumas and bobcats in the western United States. High levels of exposure in plague-endemic regions indicate the need to consider the ecology and pathobiology of plague in nondomestic felid hosts to…
Warm places, warm years, and warm seasons increase parasitizing of moose by winter ticks
Abstract:Observed links between parasites, such as ticks, and climate change havearoused concern for human health, wildlife population dynamics, and broaderecosystem effects. The one-host life history of the winter tick (Dermacentoralbipictus) links…
Viral sequences recovered from puma tooth DNA reconstruct statewide viral phylogenies
Monitoring pathogens in wildlife populations is imperative for effective management, and for identifying locations for pathogen spillover among wildlife, domestic species and humans. Wildlife pathogen surveillance is challenging, however, as sampling…
Variation in ungulate body fat Individual versus temporal effects
The use of ultrasonograhic measurements of muscle and body fat represent a relatively new data stream that can be used to address questions regarding ungulate condition. We have learned that measurements of body fat and presumably overall body…
Using simulation to compare methods for estimating density from capture–recapture data
Estimation of animal density is fundamental to wildlife research and management, but estimation via mark–recapture is often complicated by lack of geographic closure of study sites. Contemporary methods for estimating density using mark–recapture…
