Rising levels of carbon dioxide may overheat the planet and cause other environmental problems, but fears that rising CO2 levels could directly reduce plant biodiversity can be allayed, according to a new study by a University of Minnesota scientist Peter Reich. In fact, rising CO2 may actually help counteract losses of diversity from another environmental villain: the global rain of nitrogen from fertilizers and exhaust fumes. http://www.physorg.com/news179074615.html Space & Earth Thu, 03 Dec 2009 15:30:03 EST news179074615 The impact of airborne nitrogen released from the burning of fossil fuels and wide-spread use of fertilizers in agriculture is much greater that previously recognized and even extends to remote alpine lakes, according to a study published Nov. 6 in the journal Science. http://www.physorg.com/news176655560.html Space & Earth Thu, 05 Nov 2009 16:00:01 EST news176655560 Managing invasive plant species on the Great Plains has become more challenging in recent years in the face of human-caused environmental change, including the positive responses of invaders to altered atmospheric chemistry and longer growing seasons, says a University of Colorado at Boulder professor. http://www.physorg.com/news151074298.html Space & Earth Tue, 13 Jan 2009 13:04:58 EST news151074298 Increasing levels of nitrogen deposition associated with industry and agriculture can drive soils toward a toxic level of acidification, reducing plant growth and polluting surface waters, according to a new study published online in Nature Geoscience. http://www.physorg.com/news146157072.html Space & Earth Mon, 17 Nov 2008 15:11:12 EST news146157072
