River otter (Lontra canadensis) use of Phragmites australis and density estimation using genetic techniques
River otter (Lontra canadensis) use of Phragmites australis and density estimation using genetic techniques" (2011). River otters were extirpated in Nebraska in the early 1900's. In 1986 Nebraska Game and Parks Commission began reintroducing otters. In support of developing an otter management plan, I conducted research on two aspects of otter ecology in Nebraska. First, I examined otter use of...
متن کاملBilateral uric acid nephrolithiasis and ureteral hypertrophy in a free-ranging river otter (Lontra canadensis).
We report the first case of uric acid nephrolithiasis in a free-ranging river otter (Lontra canadensis). A 7 yr old male river otter collected from the Skagit River of western Washington (USA) had bilateral nephrolithiasis and severely enlarged ureters (one of 305 examined [0.33%]). The uroliths were 97% uric acid and 3% protein. Microscopic changes in the kidney were confined to expansion of r...
متن کاملNephrolithiasis in free-ranging North American river otter (Lontra canadensis) in North Carolina, USA.
The North American river otter (Lontra canadensis) serves as an indicator species for environmental monitoring, is prized as a valuable furbearer, and is a popular display animal in zoologic collections. Nephrolithiasis has been reported as a frequent problem in other free-ranging and captive otter species but is rarely reported in North American river otters. In this study, we compared the pre...
متن کاملDeciphering ecological barriers to North American river otter (Lontra canadensis) gene flow in the Louisiana landscape.
For North American river otters (Lontra canadensis) in Louisiana, statewide distribution, availability of aquatic habitats, and the absence of physical barriers to dispersal might suggest that they exist as a large, panmictic population. However, the wide variety of habitat types in this region, and the dynamic nature of these habitats over time, could potentially structure river otter populati...
متن کاملEXTRACTION 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, ...
