Habitat Selection Of Greater Sage-Grouse Centrocercus Urophasianus And Northern River Otters Lontra Canadensis In Utah, Matthew D. Westover
Theses and Dissertations
Greater sage-grouse populations have decreased steadily since European settlement in western North America. Reduced availability of brood-rearing habitat has been identified as a limiting factor for many populations. We used radio-telemetry to acquire locations of sage-grouse broods from 1998 to 2012 in Strawberry Valley, Utah. Using these locations and remotely-sensed imagery, we proceeded to 1) determine which features of brood-rearing habitat could be identified using widely available, fine-scale imagery 2) assess the scale at which sage-grouse selected brood-rearing habitat in our study area, and 3) create a predictive habitat model that could be applied across our large study area to …

Translocation Mortality And Local, Regional, And Continental Diet Of The Northern River Otter (Lontra Canadensis), Casey Craig Day
Theses and Dissertations
The northern river otter (Lontra canadensis) is a semi-aquatic carnivore whose range extends throughout most of the United States and Canada. The northern river otter experienced a severe range contraction post-European settlement, but due to widespread management has in recent decades begun to recover much of its former range and habitat. We translocated 27 river otters from Utah and Idaho to the Provo River, Utah from November 2009 through January 2012 in a reintroduction effort to restore the northern river otter to its native range. Of these 27 otters, 6 died as a result of effects related to the translocation. …
