Southern White-tailed Ptarmigan (Lagopus leucura altipetens) Population Assessment and Conservation Considerations in Colorado
Status of the southern white-tailed ptarmigan (Lagopus leucura altipetens) in Colorado was assessed from 2013-2017 using a number of metrics to determine trends in abundance, survival, site fidelity, reproductive success, resource selection, and…
Using digital photographs and pattern recognition identify individual boreal toads (Anaxyrus boreas boreas)
Individual identification of animals can provide an array of useful capture-mark-recapture information, allowing researchers to estimate survival, movement, abundance, recruitment, and capture probability (Williams et al. 2002). This information can…
Using GPS satellite transmitters to estimate survival, detectability on leks, lek attendance, inter-lek movements, and breeding season habitat use of male greater sage-grouse in northwestern Colorado
Implementing effective monitoring and mitigation strategies is crucial for conserving populations of sensitive wildlife species. Concern over the status of greater sage-grouse (Centrocercus urophasianus) populations has increased both range-wide and…
White-tailed ptarmigan occupancy report
In 2010, the white-tailed ptarmigan (Lagopus leucura; WTPT) was petitioned to be listed as threatened under the Endangered Species Act. The petitioners cited climate change and its impacts to a species dependent on alpine habitats as the main threat…
