Optimizing fecal DNA collection and storage techniques for noninvasive genetic sampling of river otters

Wildlife Society Bulletin, Volume 49, Issue 4, December 2025.
This study compared 2 non‐invasive DNA collection methods for river otters and found that fecal swabbing consistently outperformed DETs buffer storage across both temperate and tropical environments. Swabbing yielded higher PCR and genotyping success rates while reducing genotyping errors, particularly when sampling anal jelly in tropical conditions ...
