By Ruth Dasso Marlaire, Ames Research Center, Moffett Field, Calif.29 March 2011 A new NASA-funded study has revealed widespread reductions in the greenness of the forests in the vast Amazon basin in South America caused by the record-breaking drought of 2010. “The greenness levels of Amazonian vegetation — a measure of its health — decreased […]
Contact: Fariss Samarrai, fls4f@virginia.edu28 March 2011 (University of Virginia) Russia’s boreal forest – the largest continuous expanse of forest in the world, found in the country’s cold northern regions – is undergoing an accelerating large-scale shift in vegetation types as a result of globally and regionally warming climate. That in turn is creating an even […]
An unexpected side-effect of the flooding in parts of Pakistan has been that millions of spiders climbed up into the trees to escape the rising flood waters. Because of the scale of the flooding and the fact that the water has taken so long to recede, many trees have become cocooned in spiders webs. People […]
By Lewis SmithMarch 23 2011 The dramatic decline of a fruit-eating fish reputed to be among the most delicious freshwater species in the world could have severe consequences for the health of the Amazonian forests, researchers have found. Tambaqui, which have slumped by 90 per cent since the 1970s because of overfishing, have been found […]
By Michael McCarthy, Environment Editor10 March 2011 The mysterious collapse of honey-bee colonies is becoming a global phenomenon, scientists working for the United Nations have revealed. Declines in managed bee colonies, seen increasingly in Europe and the US in the past decade, are also now being observed in China and Japan and there are the […]
By JANE HAMMOND, The West Australian March 4, 2011 Up to 250,000ha of the State’s jarrah and marri forests is under attack from an army of hairy caterpillars. The creatures, known as gum-leaf skeletonizers, have stripped bare sections of the southern jarrah forest. Department of Environment and Conservation entomologist Janet Farr said the outbreak was […]
Scatterplot of the greater Central Valley, California calibration data showing the relationship between air quality score and the proportion of nitrophytic lichen abundance at each plot. Abstract: Lichens are highly valued ecological indicators known for their sensitivity to a wide variety of environmental stressors like air quality and climate change. This report summarizes baseline results […]
ScienceDaily (Mar. 4, 2011) — As carbon dioxide levels have risen during the last 150 years, the density of pores that allow plants to breathe has dwindled by 34 percent, restricting the amount of water vapor the plants release to the atmosphere, report scientists from Indiana University Bloomington and Utrecht University in the Netherlands in […]
ScienceDaily (Feb. 28, 2011) — Lodgepole pine, a hardy tree species that can thrive in cold temperatures and plays a key role in many western ecosystems, is already shrinking in range as a result of climate change — and may almost disappear from most of the Pacific Northwest by 2080, a new study concludes. Including […]
For years researchers have watched plants and animals migrate to cooler quarters in response to global warming. But a new study suggests some plants are moving downhill, drawn by increased precipitation. By Pete Spotts, Staff writerJanuary 21, 2011 For years, scientists have recorded the gradual march of plants and animals up mountain slopes and toward […]
