By Lily Whiteman, National Science Foundation Newly discovered ancient, mummified trees may reveal clues about future ecosystem responses to climate change When in Quttinirpaaq National Park in the Canadian Arctic, Ohio State University Earth scientist Joel Barker initially spotted some pieces of dead trees scattered on the barren ground near a glacier. Immediately, he knew he had found something akin to a looking glass peering into the Arctic's ecological past. The Hazen Plateau on Ellesmere...

By David Malmquist, Virginia Institute of Marine Science An international team of researchers including professor Emmett Duffy of the Virginia Institute of Marine Science has published a comprehensive new analysis showing that loss of plant biodiversity disrupts the fundamental services that ecosystems provide to humanity. Plant communities"”threatened by development, invasive species, climate change, and other factors"”provide humans with food, help purify water supplies,...

Led by scientists at Woods Hole Research Center A new study released today in the EarlyView of Ecology Letters addresses forest productivity trends in Alaska, highlighting a shift in biomes caused by a warming climate. The findings, conducted by scientists at the Woods Hole Research Center and three other institutions based in Alaska and France, linked satellite observations with an extensive and unique tree-ring data set. Patterns observed support current hypotheses regarding increased...

Tropical deforestation is intimately linked with urban dynamics and needs to be considered along with the role and effect of national and regional policies on land use decisions, and the dynamics of economic globalization in the next generation of sustainability science research, according to an Arizona State University geographer. "You just can't think of isolated farmers operating out there by themselves. They are linked to whatever are the closest urban areas," noted B.L. Turner II, whose...

A team of research biologists headed by Thomas H. Kunz, professor of biology and director of the Center of Ecology and Conservation Biology at Boston University, will conduct a symposium on the emerging scientific discipline of aeroecology at this year's American Association for the Advancement of Science (AAAS) annual meeting. Aeroecology is a new discipline whose unifying concept is a focus on the aerosphere and the myriad organisms that inhabit and depend on this aerial environment for...

Scientists address climate change effects on ecosystems from grasslands to forests to open ocean Human activities such as burning of fossil fuels and land use change have increased atmospheric carbon dioxide by 40 percent since the start of the industrial revolution, researchers have found. The result is a hotter Earth, with warmer average temperatures around the globe and a future climate system that will be more variable, and with more extreme events, says Scott Collins, a scientist at the...

When engineers restore rivers, one Kansas State University professor hopes they'll keep a smaller engineer in mind: the North American beaver. Beavers are often called ecosystem engineers because they can radically alter stream or valley bottom ecosystems, said Melinda Daniels, an associate professor of geography who recently studied the connection between beavers and river restoration. Beaver dams create diverse river landscapes, she said, and can turn a single-thread channel stream into a...

Discoveries spanning five continents and three oceans cap the United Nations' International Year of Biodiversity Global biodiversity surveys over the past few years have provided increasing evidence that our planet is in the midst of its sixth mass extinction. Plants, animals, and microorganisms are disappearing thousands of times more rapidly than they have for more than 65 million years, and for the first time in Earth's history, human activity is the predominant force behind this mass...

Unique open-air laboratory enables study of a complete ecosystem in the making How do ecosystems develop? No one really knows, yet. There is however one project, unique in the world, seeking to answer this question. In a former open-pit coal mining area in Brandenburg, Germany, a surface of six hectares was partitioned off and then left to its own resources. Scientists from the Technische Universitaet Muenchen (TUM), in collaboration with researchers from other institutions, are studying the...
