New research demonstrates that seagrass meadows are important fishing grounds all around the globe. The work highlights that there is an urgent need to start appreciating and understanding this role to be able to build more sustainable fisheries. A study led by Dr Lina Mtwana Nordlund at Stockholm University, published in the scientific journal Fish & Fisheries, examines the global extent to which these underwater meadows support fishing activity.
In many ways, Essen is the envy of cities trying to move past their industrial days.

Leipzig. Forests fulfil numerous important functions, and do so particularly well if they are rich in different species of trees. This is the result of a new study. In addition, forest managers do not have to decide on the provision of solely one service – such as wood production or nature conservation – as a second study demonstrates: several services provided by forest ecosystems can be improved at the same time. Both studies were led by scientists from Leipzig University and the German Centre for Integrative Biodiversity Research (iDiv), and published in the prestigious journal Ecology Letters.
A series of synthetic chemicals widely used in household products, food packaging and clothing have a significant effect on the development of frogs, even at low doses, according to a Purdue University study.
Per/polyfluoroalkyl substances (PFASs) are man-made chemicals used to make products stain resistant, waterproof and nonstick, and are present in foams used to fight fires. A U.S. Centers for Disease Control and Prevention (CDC) study from 2007 showed that some PFASs were present in 98 percent of blood samples collected from American adults and children for the National Health and Nutrition Examination Survey. According to the CDC, scientific studies on the impact of PFASs on human health are inconclusive.
