Improved bile-acid thin-layer chromatography to identify feces of neotropical carnivores
A modified thin-layer chromatography was used to identify carnivore feces based on their bile-acid patterns. Our method is safer and makes the identification of bile acids more objective. We applied the technique to feces of 2 sympatric canids in the Neotropics, the culpeo (Pseudalopex culpaeus) and...
