Mink (Mustela vison), river otters (Lontra canadensis) , and muskrats (Ondatra zibethicus) were collected from the upper Hudson River drainage during the 1998-1999 and 1999-2000 trapping seasons. Liver samples from 162 animals (102 mink, 40 otter, and 20 muskrats) were analyzed for lipids and PCBs as Aroclors. PCB concentrations were elevated for mink and otters collected from the Hudson River ...

We present a literature review of the sucking louse family Echinophthiriidae, its five genera and twelve species parasitic on pinnipeds (fur seals, sea lions, walruses, true seals) and the North American river otter. We give detailed synonymies and published records for all taxonomic hierarchies, as well as hosts, type localities and repositories of type material; we highlight significant refer...

Radiotelemetry provides valuable information about wildlife populations that is often unattainable using other methods. Many vertebrate species can carry radiotransmitters on collars or harnesses, but radiotelemetry be more problematic for species. River otters (Lontra canadensis) are typically radiomarked by surgically implanting intra-abdominal transmitters under general anesthesia. However, ...

up to now, there is no habitat suitability index model for common otter in iran. this species is an index species for clean ecosystems and consequently, an important animal. model prepared, considering dependent variables to show vital needs for this animal in the shenrood river located in the deylaman-dorfak prohibited hunting area in iran. hep method was applied and important factors were sel...

We assessed the distribution and habitat use of Eurasian otter Lutra lutra on middle course River Segura its tributaries (Murcia, SE Spain) within framework project LIFE13BIO/ES/001407 RIPISILVANATURA (2014–2019). Between April 2016 June 2018, we surveyed for spraints 42 sampling stretches (mean length ± SD = 0.5 0.2 km), covering a 109.8 km long section river. The study time frame coincided wi...
