Megalocytivirus: A Review of Epidemiology, Pathogenicity, Immune Evasion, and Prevention Strategies
Reviews in Aquaculture, Volume 17, Issue 3, June 2025.ABSTRACT Megalocytivirus, a large double‐stranded DNA virus belonging to the Iridoviridae family, has infected over 100 species of fish, leading to significant economic losses in the aquaculture, food, and ornamental fish industries. These viruses exhibit icosahedral symmetry and have diameters ranging from 120 to 200 nm.

Environmental DNA, Volume 7, Issue 3, May–June 2025.We used eDNA to assess seasonal biodiversity patterns in a tropical river in French Guiana. Our results show that rainfall increases the detection of terrestrial species through eDNA washout and leads to species homogenization via increased eDNA transport.

The impact of increasing turbidity on the predator–prey interactions of freshwater fishes
Freshwater Biology, Volume 70, Issue 1, January 2025.Abstract Human activities are exacerbating environmental change globally. Turbidity in freshwater systems is increasing due to extreme weather events and intensification of activities such as deforestation, urbanisation, agriculture and altering water flow with dams and other structures.

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
