Beyond Hard Parts: Metabarcoding Advances Dietary Resolution in Threatened Amazonian Elasmobranchs
Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.ABSTRACT Elasmobranchs are highly vulnerable and are considered one of the most threatened vertebrates worldwide. Insights into diet can improve conservation measures. The bias of traditional morphological methods towards taxa with distinctive hard parts makes metabarcoding analysis a complementary tool to assess diet composition. Here, we analysed the

Environmental DNA, Volume 8, Issue 2, March/April 2026.Novel species‐specific eDNA qPCR assay for endangered Hong Kong Grouper (Epinephelus akaara) reveals low shedding rates and rapid decay. Rare, trace detections across Hong Kong waters confirm population rarity, demonstrating eDNA as a powerful non‐invasive tool for monitoring threatened marine fishes. ABSTRACT The Hong Kong Grouper (Epinephelus akaara)

Tracking Aquatic Biodiversity With Environmental DNA: A Study in Quebec's Mining Region
Environmental DNA, Volume 7, Issue 5, September–October 2025.This study assesses the effectiveness of environmental DNA (eDNA) for monitoring fish species in mining‐impacted waters of Quebec's James Bay region. eDNA analyses detected key species, including culturally significant ones, and revealed potential biodiversity impacts, such as reduced detectability of lake sturgeon in areas with habitat disturbance and
