River otter chemical immobilization and field surgery using nonscheduled drugs

چکیده
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, surgical requirements and restrictions some immobilizing drugs may limit options river with in the field. To address these issues, we developed a protocol chemically live-captured nonscheduled (by estimated weight class; dexmedetomidine 0.06 mg/kg nalbuphine 1.2 mg/kg) conducting field surgeries at capture sites. We implanted 23 southern Illinois during November 2018−March 2020. A plane of anesthesia suitable surgery was maintained isoflurane (1−4%). After surgery, were reversed atipamezole released 30−60 min. recorded one surgery-related mortality post-surgery mortality. Our method radiomarking minimized stress handling time without compromising their health demonstrated efficacy less-restricted chemical immobilization agents otters.

Evaluating River Otter Demography Using Noninvasive Genetic Methods
The decline in river otter (Lontra canadensis) populations during the late nineteenth and early twentieth centuries throughout North America has led to protective status and strict harvest regulations. Despite sustained interest in protecting river otters, relatively few contemporary studies have evaluated the current status of populations, especially in California. An effective way to estimate...

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...
