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
