Vegetation around the world is on the move, and climate change is the culprit, according to a new analysis of global vegetation shifts led by a University of California, Berkeley, ecologist in collaboration with researchers from the U.S. Department of Agriculture Forest Service. In a paper published today in the journal Global Ecology and Biogeography, researchers present evidence that over the past century, vegetation has been gradually moving toward the poles and up mountain slopes, where...

The majestic animals most closely associated with the African savanna "“ fierce lions, massive elephants, towering giraffes "“ may be relatively minor players when it comes to shaping the ecosystem. The real king of the savanna appears to be the termite, say ecologists who have found that this humble creature contributes mightily to a grassland in central Kenya. Robert M. Pringle, a research fellow at Harvard University, and colleagues show that termite mounds greatly enhance...

Marine Board-ESF presents position paper at EU Maritime Day 2010 Food from fisheries, trade and transport through shipping, income from tourism and recreation "“ we rely on our seas. Managing this rich resource is a challenge that calls for reframing humans as integral parts of marine ecosystems, say scientists from three of Europe's leading marine organizations in a new report launching on 19 May ahead of EU Maritime Day 2010. The Marine Board-European Science Foundation, the...

Ecosystems are essential for preserving the quality of life of human beings, and society should be aware of this, according to Ms Miren Onaindia, biologist and person responsible for the Forest Ecology and Natural Resources research team at the University of the Basque Country (UPV/EHU). This group has been investigating the woods and forest of the Autonomous Community of the Basque Country (CAV-EAE) for twenty years now. In recent times they have focused on evaluating the situation of...

Using repeat photography to enhance understanding of riparian areas Riparian areas, ecosystems caught between the land and the stream, are subject to spatial and temporal variability. Effectively managing and protecting riparian areas as well as other ecosystems require understanding these concepts. Fortunately, scientists are investigating new approaches in experiential learning, or learning from direct experiences. One of those approaches is photography. By taking photographs of a specific...

Following an intense study of agricultural ecosystems near Montreal, a new tool that enables the simultaneous analysis and management of a wide range of ecological services has been developed by Ciara Raudsepp-Hearne of McGill University's Department of Geography, Elena Bennett of the McGill School of Environment, and Garry Peterson of the Stockholm Resilience Centre at Stockholm University. Environmental management typically focuses on nature's resources like food, wildlife and timber, but...

Results from Long-Term Ecological Research show importance of resources and processes supplied by ecosystems Humans are sustained by a multitude of processes and resources in the environment around us. These benefits are called "ecosystem services," and include products like clean drinking water and the provision of foods such as crops and spices. On Thursday, March 4, the National Science Foundation (NSF) will host a symposium titled, "Ecosystem Services in a Changing World: Perspectives...

In the natural stream communities of Trinidad, guppy populations live close together, but evolve differently. Upstream, fewer predators mean more guppies but less food for each; they grow slowly and larger, reproduce later and less, and die older. Downstream, where predators thrive, guppies eat more, grow rapidly, stay small, reproduce quickly and die younger. While it is clear to ecologists that an ecosystem shapes the evolution of animals living in it, population biology experts such as...

New animal tracking techniques suggest the public may accept small, managed populations of wolves in parks Researchers writing in the February issue of BioScience propose reintroducing small, managed populations of wolves into national parks and other areas in order to restore damaged ecosystems. The populations would not be self-sustaining, and may consist of a single pack. But the BioScience authors suggest that even managed populations could bring ecological, educational, recreational,...
