Thinking Big by Burning Small

A recent paper by scientists from Wits University in South Africa shows how creative fire management can increase habitat for wildebeest and other grazing animals in national parks.(image)



As Oceans Warm, the World's Kelp Forests Begin to Disappear

Mon, 20 Nov 2017 12:26:00 EST

A steady increase in ocean temperatures — nearly 3 degrees Fahrenheit in recent decades — was all it took to doom the once-luxuriant giant kelp forests of eastern Australia and Tasmania: Thick canopies that once covered much of the region’s coastal sea surface have wilted in intolerably warm and nutrient-poor water. Then, a warm-water sea urchin species moved in. Voracious grazers, the invaders have mowed down much of the remaining vegetation and, over vast areas, have formed what scientists call urchin barrens, bleak marine environments largely devoid of life.(image)



Maps reveal landscape beneath Antarctica's weak underbelly

Mon, 20 Nov 2017 09:39:00 EST

A UK team of researchers has produced high-resolution maps of the bed beneath a major glacier in West Antarctica, which will help them predict future sea-level rise from this region. Radar surveys of the land beneath Pine Island Glacier have revealed a diverse landscape under the ice with some surprises. The results are published today (20 November 2017) in the journal Nature Communications.(image)



How the Alaska Pipeline Is Fueling the Push to Drill in the Arctic Refuge

Fri, 17 Nov 2017 15:20:00 EST

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. (image)



Seagrass is a Key Fishing Ground Globally

Fri, 17 Nov 2017 11:58:00 EST

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.(image)



The Importance of Biodiversity in Forests Could Increase Due to Climate Change

Fri, 17 Nov 2017 11:33:00 EST

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.(image)



Virginia Tech works to protect Africa's crops against invasive pests

Fri, 17 Nov 2017 08:11:00 EST

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.(image)
