Asian small‐clawed otter (Aonyx cinerea) urolithiasis prevalence in North America

AbstractThe prevalence of urolithiasis in the North American Asian small‐clawed otter (Aonyx cinerea) population was determined through a retrospective survey. A questionnaire regarding diet and radiographic or necropsy evidence of urolithiasis was sent to the 16 North American institutions or individuals listed in the Asian Small‐Clawed Otter North American Regional Studbook. Completed forms were returned by 75% of questionnaire recipients.Individual surveys or necropsy reports were received for 79.8% of the living or dead animals listed as comprising the North American population. Renal calculi were detected in 66.1%, and cystic calculi in 23.2%, of the captive adult population that had been radiographed or necropsied. All otters with cystic calculi also had renal calculi. Bilateral renal calculi occurred in 83.8% of affected otters. Both males (61.2%) and females (72%) were frequently affected. The prevalence of urolithiasis in wild‐born otters was 76.7%, and in adult (≥1 year) captive‐born otters it was 53.8%. The higher prevalence in wild‐born otters may be a reflection of the older mean age at which they were first evaluated. In the overwhelming majority of otters with renal calculi, the calculi were multiple and diffusely distributed throughout the renal parenchyma. Renal and cystic calculi analyzed were primarily composed of calcium oxalate or urates. Glucosuria was infrequently reported. Necropsies of dependent neonates (≤ 2 months old) that died revealed cystic calculi in one animal.Renal disease was the cause of, or a contributing factor in, the deaths of all older animals whose necropsy reports were reviewed. The captive diet may be a contributing factor to urolith formation and progression.

A captive behavioral enrichment study with Asian small‐clawed river otters (Aonyx cinerea)

AbstractAsian small‐clawed river otters (Aonyx cinerea) were given the opportunity to hunt for and capture live crickets (Acheta domestica) in a public interactive display. The otters learned the experimental routine during the first day of exposure. Different response levels were recorded at each of three capture sites, A, B, and C. The animals showed continued motivation for hunting despite the fact that there was no deprivation and the crickets represented an insignificant part of the diet. Besides live crickets, other items—cat food, dead crickets, and gelatin capsules—were introduced for five days each. The otters made the most captures per opportunity for live crickets, followed, in order of preference, by dead crickets, cat food, and gelatin capsules. Although gelatin capsules were found to be the least motivating prey item, the otters hunted for them whenever they were offered. Thus, any active opportunity to produce a change in their environment was rewarding to the otters.

Protides of the Mustelidae: Comparative study of plasma lactate dehydrogenases

1.1. Plasma LDH levels are described for fifteen species of Mustelidae and two Viverridae. All species except Lutra canadensis had LDH activities two to four times higher than the human plasma control.2.2. Conepatus leuconotus (Mustelidae) and Arctictis binturong (Viverridae) were the only species examined with an LDH-1 mobility different from the human LDH-1, at 94 and 60 per cent of the control, respectively.3.3. The LDH-5 mobility of all of the carnivores was the same, and greater than that of the human control.4.4. Plasma LDH of L. canadensis and Aonyx cinerea were almost entirely in the form of LDH-1 isozyme.5.5. Some species had a unique LDH isozyme composition which easily distinguished them from other species of the family.
