By 2100 only 18% to 45% of the plants and animals making up ecosystems in global, humid tropical forests may remain as we know them today, according to a new study led by Greg Asner at the Carnegie Institution's Department of Global Ecology. The research combined new deforestation and selective logging data with climate-change projections. It is the first study to consider these combined effects for all humid tropical forest ecosystems and can help conservationists pinpoint where their...

Redwood forest ecosystem of northern California depends on fog to stay hydrated during rainless summers As the mercury rises outdoors, it's a fitting time to consider the effects of summertime droughts and global warming on ecosystems. Complex interactions among temperature, water cycling, and plant communities create a tangled web of questions that need to be answered as we face a rapidly changing climate. Drs. Emily Limm and Todd Dawson (University of California, Berkeley) recently tackled...

STONY BROOK, N.Y., July 9 /PRNewswire-USNewswire/ -- A compendium on trophic cascades and how they operate in the world's major ecosystems has been published for the first time. The term "trophic cascades" refers to the follow-on effects of top predator removal from an ecosystem, and, until now, there has not been a comprehensive synthesis of this phenomenon. Evidence accumulated in this volume indicates that trophic cascades operate in nearly all ecosystems around the world, both at sea...

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...

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...
