Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves

Conservation Biology, EarlyView.
Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.

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

Ecological 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.

Ecosystem Impacts of the Landing Obligation for Unwanted Catch in Thermaikos Gulf (Greece)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Discards by marine commercial fisheries have been an issue of major concern to the scientific community in recent years. We modeled the ecological and trophic consequences of a mandatory landing obligation (LO) regulated by the reformed Common Fisheries Policy [Regulation (EU) 1380/2013] on the Thermaikos Gulf ecosystem (northwestern Aegean ...

Assessment of a Baited Remote Underwater Video Method to Evaluate American Lobster (Homarus americanus) Response to Baits in Nature

Fisheries Management and Ecology, EarlyView.
ABSTRACT The American Lobster (Homarus americanus) is the target of an extensive fishery in the Northwest Atlantic, yet there is no systematic method for evaluating relative performance of baits for the fishery. We used Baited Remote Underwater Video (BRUV) to assess lobster attraction to commercial baits versus natural prey.
