How Many River Otters Inhabit Yellowstone Lake? An Assessment with Fecal and Hair DNA Analyses

High-altitude diving in river otters: coping with combined hypoxic stresses.

River otters (Lontra canadensis) are highly active, semi-aquatic mammals indigenous to a range of elevations and represent an appropriate model for assessing the physiological responses to diving at altitude. In this study, we performed blood gas analyses and compared blood chemistry of river otters from a high-elevation (2357 m) population at Yellowstone Lake with a sea-level population along ...

Assessing the Impotance of Cutthroat Trout to River Otters in Yellowstone Lake

EXTRACTION TECHNIQUE AND MICROSATELLITE PRIMERS ON GENOTYPING SUCCESS AND ERROR RATES OF RIVER OTTER (LONTRA CANADENSIS) FAECAL DNA by

My thesis contains two chapters that have been prepared as manuscripts for publication. The first chapter, " The effects of diet, extraction technique and microsatellite primers on genotyping success and error rates of river otter (Lontra canadensis) faecal DNA " comprises the main effort of my work as a Master of Sciences student and will be submitted to Molecular Ecology. The second chapter, ...

River Otters in Prince William Sound and Kenai Fjords National Park: Distribution, Relative Abundance, and Minimum Population Size Based on Coastal Latrine Site Surveys Interagency Collaborative Project

The goals of this study were: 1. To establish baseline information on the distribution, relative abundance, and minimum number alive of river otters in Kenai Fjords National Park (KFNP) using latrine site surveys and DNA fingerprinting of fecal samples. 2. To establish baseline information on the distribution, relative abundance, and minimum number alive of river otters in Prince William Sound ...

Crustal deformation of the Yellowstone–Snake River Plain volcano-tectonic system: Campaign and continuous GPS observations, 1987–2004

[1] The Yellowstone–Snake River Plain tectonomagmatic province resulted from Late Tertiary volcanism in western North America, producing three large, caldera-forming eruptions at the Yellowstone Plateau in the last 2 Myr. To understand the kinematics and geodynamics of this volcanic system, the University of Utah conducted seven GPS campaigns at 140 sites between 1987 and 2003 and installed a n...
