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

open access: yesEcological Entomology, EarlyView.
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.
