Assessing fish diversity in abandoned mining ponds in Madre de Dios, Peru, using environmental DNA

Environmental DNA, Volume 6, Issue 1, January–February 2024.
We surveyed four lentic systems in Madre de Dios, Peru: two abandoned mining ponds created by ASGM and two unmined oxbow lakes as a reference to assess fish recolonization. We compared two alternative eDNA processing methods and contrasted our results with historic data from traditional biodiversity monitoring. Our results indicate that eDNA could be a

Fresh vs. Preserved Specimens: Length‐Weight Relationships of Fishes from the Western Amazon (Napo Basin, Ecuador)

Journal of Applied Ichthyology, Volume 2024, Issue 1, 2024.
Length‐weight relationship (LWR) studies are important for fish taxonomical analysis, ecological assessments, management, and conservation practices. Although LWR studies can use measurements of either fresh or preserved specimens, few studies have directly compared these methods. This study analyzed the effect of preservation on LWR of ten small‐sized
