• The war over the Arctic National Wildlife Refuge (ANWR) — one of the most contentious and enduring environmental fights in U.S. history — is once again heating up. 

  • 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.

  • 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.

  • As invasive and indigenous insect pests continue to wreak havoc on crops across Africa, a Virginia Tech-led project is intensifying its work to coordinate a response that looks beyond geographic and financial barriers.

    Stopping crop losses requires working across borders, said Muni Muniappan, director of the Virginia Tech-led Feed the Future Innovation Lab for Integrated Pest Management. “Fighting these pests in just a few of these countries is futile, because it will continue to thrive in the countries where we are not working,” he said.

  • Geologists have long debated how and when the Colorado River made its first connection to the ocean. In a new study, a team led by the UO’s Becky Dorsey has helped pull the river’s story together.

    The river did not, as many thought, simply roar down out of the Colorado Plateau and pour into the Gulf of California.

  • Many Pacific Island nations will lose 50 to 80 percent of marine species in their waters by the end of the 21st century if climate change continues unchecked, finds a new Nippon Foundation-Nereus Program study published in Marine Policy. This area of the ocean is projected to be the most severely impacted by aspects of climate change.

  • Deforested areas of the Amazon Basin have a limited ability to recover because of recent changes in climate, a study shows.

  • Traditional toxicity testing underestimates the risk that pharmaceutical and personal care product pollution poses to freshwater ecosystems. Criteria that account for ecological disruption – not just organism death – are needed to protect surface waters, which are under pressure from a growing population and escalating synthetic chemical use. So reports a new study published this week in Elementa.

  • The presence of artificial sweeteners in rural groundwater shows evidence for contamination by local septic system wastewater, researchers from the University of Waterloo have found.

  • Pesticides significantly reduce the number of pollen grains a bumblebee is able to collect, a new University of Stirling study has found.
