Chuck Roe is studying calcium oxalate urolithiasis in Asian small-clawed otters (Aonyx cinereus). Asian small-clawed otters are a vulnerable species who have a strikingly high prevalence (66-100%) of calcium oxalate uroliths when held in collections but the disease in the wild population appear to be rare. The diet fed to Asian small-clawed otters in zoos and aquariums is mostly commercial pet food and fish while the wild diet is dominated by crabs. His research focuses on the differences in nutrition between the wild and managed diet that may underlie the high prevalence of calcium oxalate uroliths. The expected outcome of this research is to improve the zoo and aquarium diet in a manner that will reduce the prevalence of urolithiasis.
