Phylogeography and demographic history of the neotropical otter (Lontra longicaudis).
The Neotropical otter (Lontra longicaudis) is a medium-sized semiaquatic carnivore with a broad distribution in the Neotropical region. Despite being apparently common in many areas, it is one of the least known otters, and genetic studies on this species are scarce. Here, we have investigated its genetic diversity, population structure, and demographic history across a large portion of its geo...
متن کاملFeeding ecology of the Neotropical otter Lontra longicaudis in the Lower Arroio Grande River, southern Brazil.
The present study was based on the analysis of spraints (n = 294) collected between December 2005 and November 2007. The importance of each type of prey was determined by absolute and relative frequency. Niche breadth was also estimated. The results were reported as mean (± SD) of relative frequencies. Fish were the main prey found in spraints (57.8 ± 7.0%). Fish from Callichthyidae family were...
متن کاملGenetic diversity of the Neotropical otter (Lontra longicaudis Olfers, 1818) in Southern and Southeastern Brazil.
The Neotropical otter is one of the least known otter species, and it is considered to be threatened to various degrees throughout its geographic range. Little information exists on the ecological characteristics of this species, and no genetic study has been published about it until now, hampering the design of adequate conservation strategies for its populations. To contribute with genetic in...
متن کاملRiver 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...
