Using maternal mule deer movements to estimate timing of parturition and assist fawn captures
Movement patterns of maternal ungulates have been used to determine parturition dates and aid in locating fawns, which may be important for understanding reproductive rates (e.g., pregnancy and fetal), but such methods have not been validated for…
Using genetic diversity to inform conservation efforts for native Cutthroat Trout of the Southern Rocky Mountains
Recent research on native Cutthroat Trout Oncorhynchus clarkii of the southern Rocky Mountains suggests a convoluted taxonomy confused by stocking in the early 1900s that obscured the native distributions of these fish. DNA recovered from the few…
Using environmental features to model highway crossing behavior of Canada lynx in the Southern Rocky Mountains
Carnivores are particularly sensitive to reductions in population connectivity caused by human disturbance and habitat fragmentation. Permeability of transportation corridors to carnivore movements is central to species conservation given the large…
Using digital photographs and pattern recognition to identify individual boreal toads (Anaxyrus boreas boreas)
Individual identification of animals can provide an array ofuseful capture-mark-recapture information, allowing researchers to estimate survival, movement, abundance, recruitment, and capture probability (Williams et al. 2002). This information can…
Using auxiliary telemetry information to estimate animal density from capture–recapture data
Estimation of animal density is fundamental to ecology, and ecologists often pursue density estimates using grids of detectors (e.g., cameras, live traps, hair snags) to sample animals at a study site. However, under such a framework, reliable…
Use of predictive distribution models to describe habitat selection by bats in Colorado, USA
Numerous processes operating at landscape scales threaten bats (e.g., habitat loss, disease). Temperate bat species are rarely examined at commensurate scales because of logistical and modeling constraints. Recent modeling approaches now allow for…
Urbanization impacts apex predator gene flow but not genetic diversity across an urban‐rural divide
Apex predators are important indicators of intact natural ecosystems. They are also sensitive to urbanization because they require broad home ranges and extensive contiguous habitat to support their prey base. Pumas (Puma concolor) can persist near…
Understanding and managing human tolerance for a large carnivore in a residential system
Human tolerance for interactions with large carnivores is an important determinant of their persistence on the landscape, yet the relative importance of factors affecting tolerance is not fully understood. Further, the impact of management efforts to…
Time-varying predatory behavior is primary predictor of fine-scale movement of wildland-urban cougars
Background
While many species have suffered from the detrimental impacts of increasing human population growth, some species, such as cougars (Puma concolor), have been observed using human-modified landscapes. However, human-modified habitat can be…
Three pathogens in sympatric populations of pumas, bobcats, and domestic cats: implications for infectious disease transmission
Anthropogenic landscape change can lead to increased opportunities for pathogen transmission between domestic and non-domestic animals. Pumas, bobcats, and domestic cats are sympatric in many areas of North America and share many of the same…
