Flooding affects fluctuating asymmetry but not growth of a riparian orbweaving spider

Ecological Entomology, Volume 51, Issue 3, Page 547-557, June 2026.
In a mesocosm experiment we assessed the impact of flood on aquatic insect emergence and on spider development using geometric morphometric analysis of fluctuating asymmetry. We observed 45% higher emergence in flooded mesocosm throughout the season. Spiders did not grow bigger but exhibited ~15% lower fluctuating asymmetry than in controls.

Freshwater Mussel Anodonta cygnea Reduces Concentration, Germination Rate and Infectivity of Pathogenic Oomycete Saprolegnia spp. Spores

Freshwater Biology, Volume 71, Issue 6, June 2026.
ABSTRACT Saprolegniosis, also known as water mould, is a lethal disease caused by Saprolegnia oomycetes that threatens freshwater animals including fish, amphibians, and crustaceans, as well as aquaculture. It causes biodiversity loss and population declines, including those of endangered fishes.
