European restoration and habitat preservation
Several important marine habitats in the European oceans are about to disappear. No complete mapping of existing or threated marine habitats in Europe are available, nor a full overview of the restoration potential of degraded habitats. These are the objectives of the EU financed four-year MERCES-project.

Measuring microplastics in blue mussels
Many different methods have been developed to monitor microplastics, although the lack of
standardisation limits comparability. It is vital to carry out standardised monitoring to
acquire a baseline understanding of microplastic contamination in the Norwegian environment. A new
project aimed to identify suitable methods for monitoring microplastics in blue mussels and sediments - with sampling stations around the coast of Norway.

95% of Fulmars in the North Sea Had Plastic in Their Stomachs
Plastic in the form of very small particles, so-called ‘microplastic’, pollutes much of the marine environment. Scientists find microplastics in the majority of samples collected from the world's oceans.

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.

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.

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.
