Microplastics in agricultural soils: A reason to worry?
Microplastics are increasingly seen as an environmental problem of global proportions. While the focus to date has been on microplastics in the ocean and their effects on marine life, microplastics in soils have largely been overlooked. Researchers are concerned about the lack of knowledge regarding potential consequences of microplastics in agricultural landscapes from application of sewage sludge.

Anti-Sea lice drugs may pose hazard to non-target crustaceans
To treat sea lice infections in aquaculture, veterinary medicines are widely used. However, these medicines may cause collateral damage.

Sea ice algae blooms in the dark
Researchers from Aarhus University have measured a new world record: Small ice algae on the underside of the Arctic sea ice live and grow at a light level corresponding to only 0.02% of the light at the surface of the ice. Algae are the primary component of the Arctic food web and produce food far earlier in the year than previously thought.

Chinese lakes less polluted after sanitation clean-up
Pollution levels in many Chinese lakes have declined somewhat from high levels in the past decade, helped by billion-dollar investments in urban sewers and waste water treatment.

Policy Brief ‘Nourishing Blue Economy and Sharing Ocean Knowledge’
Ten innovative EU projects to build ocean observation systems that provide input for evidence-based management of the ocean and the Blue Economy, have joined forces in the strong cluster ‘Nourishing Blue Economy and Sharing Ocean Knowledge’. Under the lead of the EuroSea project, the group published a joint policy brief listing recommendations for sustainable ocean observation and management.

Turf Wars: The New Battle Front of Globally Declining Kelp Forests
For decades in Norway, the species rich kelp forests have been grazed down by sea urchins, leaving behind nothing but naked rocks. As a result of climate change, sea urchins along parts of the Norwegian coast are now on retreat, while the same climate changes are probably the cause of the new, big threat towards the global kelp forests: the rise of turf algae.

JPI Oceans Knowledge Hub on the Integrated Assessment of Chemical Contaminants and their Effects on the Marine Environment
In a time of environmental awareness, spurred on by the possibility that our world is threatened by climate change, it is important to remember that there are other anthropogenic pressures, which are also essential for addressing the protection of the marine and coastal environment. Pollution is a global, complex issue that contributes to biodiversity loss and poor environmental health and comes from the production and release of many of the synthetic chemicals that we use in our daily lives. Chemical contaminants are often underrepresented as a major contributor of environmental deterioration.

How are river ecosystems affected by regulation?
More and more rivers are regulated to serve human needs such as flood protection, transport, irrigation, hydropower generation or drinking water supply. Do altered flow dynamics affect organisms that inhabit the river bottom? And how does river flow interact with other ecosystem stressors like acidification or nutrient enrichment? A recent research project combined a flume experiment with findings from 64 regulated and unregulated river sites in Norway and Germany to find the answers.

A new approach to amplifying DNA; A small paradigm shift within molecular photocopying
Analyzing DNA is useful for a number of vital applications. This includes diagnosis and monitoring of diseases, identification of criminals, and studying the function of a targeted segment of DNA. However, methods used for analyses often require more DNA than may be available in a typical sample. ‘Therefor, amplification is necessary, but not always straightforward. The most widely used amplification or photocopying method is the polymerase chain reaction (PCR). A new PCR method could help the amplification process, and thus develop robust assays that previously would not have been possible.

Effects of multiple stresses hydropower, acid deposition and climate change on water chemistry and salmon populations in the River Otra, Norway
In order to predict and manage the long-term health and status of the Otra river's salmon populations, a new study has considered acidification as part of a multiple stress combination affecting the river alongside hydropower and climate change.

Over Half of Fish Stocks Worldwide Are Missing the Opportunity to Maximize Sustainable Yields
New research published today in Conservation Letters finds that over half of fish stocks are below levels that would yield greater long-term catches, enhance food security and avoid overfishing. Of those fish stocks, over a third are at 80 percent below sustainable catch.
