DOI: 10.1002/ece3.9582
Abstract: Abstract Measuring individual fitness empirically is required to assess selective pressures and predicts evolutionary changes in nature. There is, however, little consensus on how fitness should be empirically estimated. As fitness proxies vary in their… read more here.

DOI: 10.1002/jwmg.21470
Abstract: Bacterial pneumonia is a threat to bighorn sheep (Ovis canadensis) populations. Bighorn sheep in the East Humboldt Mountain Range (EHR), Nevada, USA, experienced a pneumonia epizootic in 2009– 2010. Testing of mountain goats (Oreamnos americanus)… read more here.

DOI: 10.1016/j.biocon.2020.108639
Abstract: Abstract Species conservation requires monitoring and management that extends beyond the local population, yet studies evaluating population trends and management outcomes across the spatial range of a species remain rare. We conducted the first range-wide… read more here.

DOI: 10.1016/j.vaccine.2017.02.006
Abstract: Mannheimia haemolytica is an important pathogen of pneumonia in bighorn sheep (BHS), consistently causing 100% mortality under experimental conditions. Leukotoxin is the critical virulence factor of M. haemolytica. In a 'proof of concept' study, a… read more here.

DOI: 10.1038/s41598-019-51370-y
Abstract: Monitoring dispersal, habitat use, and social mixing of released ungulates is crucial for successful translocation and species conservation. We monitored 127 female bighorn sheep (Ovis canadensis) released in three populations from 2000 to 2009 to… read more here.

DOI: 10.1071/wr20069
Abstract: Abstract Context. Wildlife biologists accumulate large quantities of images from remote cameras, which can be time- and cost-prohibitive to archive and analyse. Remote-camera projects would benefit from not setting cameras longer than needed and not… read more here.

DOI: 10.1111/mec.14586
Abstract: Determining how species move across complex and fragmented landscapes and interact with human‐made barriers is a major research focus in conservation. Studies estimating functional connectivity from movement, dispersal or gene flow usually rely on a… read more here.

Abstract: Rumination is the repeated process of regurgitation of a food bolus, followed by chewing, swallowing, and regurgitation, which enhance nutrient assimilation. Time spent in lateral recumbency (i.e., bedded, lying) has often been used as a… read more here.
