Environmentally relevant levels of four psychoactive compounds vary in their effects on freshwater fish condition: a brain concentration evidence approach
Jörg Oehlmann –– Due to their optimised biological activity, pharmaceuticals are specifically relevant among micropollutants in the auqatic environment. This is even more true for psychoactive drugs, which may also alter the behaviour of aquatic organisms. In this publication the authors have analysed the effects of four psychoactive pharmaceuticals on fish and found considerable differences in their effect profile, ranging from no effect to reduced condition and increased mortality.
Treating coral bleaching as weather: a framework to validate and optimize prediction skill
James Reimer –– An excellent new method of improving coral bleaching predictions, providing a way forward for even more future improvement in this field.
Ocean warming is the key filter for successful colonization of the migrant octocoral Melithaea erythraea (Ehrenberg, 1834) in the Eastern Mediterranean Sea
Xavier Pochon –– This case study used various sclerite measurements of the endemic Red Sea octocoral Melithaea erythraea along the Southeast Mediterranean Sea to demonstrate a 'tropicalization' effect of the Mediterranean Sea due to recent warming. octocoral Melithaea erythraea Ehrenberg, 1834 along the SEMS coast, using sclerite oxygen and carbon stable isotope composition (δ18OSC and δ13CSC), morphology, and crystallography.
Organic eutrophication increases resistance of the pulsating soft coral Xenia umbellata to warming
James Reimer –– The role that benthos asides from scleractinian corals will play on future coral reefs is not yet well studied, and this work represents an important step forward in understanding what role some soft corals may have.
Shape of attachment structures in parasitic isopodan crustaceans: the influence of attachment site and ontogeny
James Reimer –– A work of excellent quality focusing on parasitic isopods, with detailed, beautiful, and very useful figures.
How caged salmon respond to waves depends on time of day and currents
María Ángeles Esteban –– There are many limit factors which affect salmon growth in farms. Among them there are diseases, pest control, and water quality. In this paper it is study one way to circumvent such problems which implies to move production into more exposed locations with greater water exchange. Farming in exposed locations is better for the environment, but may carry unforeseen costs for the fish in those farms. This study employed two major fish monitoring methods to determine the ability of Atlantic Salmon (Salmo salar) to cope with wavy conditions in exposed farms.
No evidence that crayfish carcasses produce detectable environmental DNA (eDNA) in a stream enclosure experiment
Xavier Pochon –– This is a great contribution to the increasing number of studies investigating the release and detectability of environmental DNA from a range of aquatic organisms. This time, the invasive red swamp crayfish (Procambarus clarkii) in a controlled stream enclosure experiment.
Meiofaunal communities and nematode diversity characterizing the Secca delle Fumose shallow vent area (Gulf of Naples, Italy)
Craig Moyer –– Meiofaunal communities at hydrothermal vents have been rarely investigated, this study helps illuminate this portion of the hydothermal vent ecosystem.
Proliferating activity in a bryozoan lophophore
James Reimer –– As the two reviewers stated, this is a pioneering work and a significant contribution to understanding of lophophores and cell structure.
Future sea-level rise drives rocky intertidal habitat loss and benthic community change
Carlos de Rezende –– The manuscript addresses a contemporary subject and works with an important transition environment. Studies like this can be an important key to understanding these changes under a new climate regime.
