Water resources can become strained by both natural factors such as drought and by human factors such as unsustainable use. Water resource managers can develop practices to reduce overuse of water resources, but they cannot prevent droughts, so distinguishing the causes of water stress can be useful. However, since the two factors often occur at the same time, separating them can be difficult. http://phys.org/news282553750.html Space & Earth Fri, 15 Mar 2013 08:20:01 EST news282553750 Ocean mussels could be key to helping scientists predict more accurately the rise in sea levels caused by the melting of the Greenland Ice Sheet. http://phys.org/news275042952.html Space & Earth Tue, 18 Dec 2012 08:49:18 EST news275042952 New genetic analysis has revealed that many Amazon tree species are likely to survive man-made climate warming in the coming century, contrary to previous findings that temperature increases would cause them to die out. http://phys.org/news274641750.html Biology Thu, 13 Dec 2012 17:22:42 EST news274641750 In the bird world, they make endangered condors seem almost commonplace. The unique Great Gray Owls of Yosemite, left to evolve after glacial ice separated them from their plentiful Canadian brethren 30 millennia ago, are both a mystery and concern to the scientists charged with protecting them. http://phys.org/news270098009.html Biology Mon, 22 Oct 2012 04:13:39 EST news270098009 (Phys.org) -- The oceans have warmed in the past 50 years, but not by natural events alone. http://phys.org/news258612967.html Space & Earth Mon, 11 Jun 2012 05:56:21 EST news258612967 As global temperatures rise, the most threatened ecosystems are those that depend on a season of snow and ice, scientists from the nation's Long Term Ecological Research (LTER) Network say."The vulnerability of cool, wet areas to climate change is striking," says Julia Jones, a lead author in a special issue of the journal BioScience released today featuring results from more than 30 years of LTER, a program of the National Science Foundation (NSF). http://phys.org/news252861230.html Space & Earth Fri, 06 Apr 2012 00:00:01 EST news252861230 Organisms living on small islands are particularly threatened by extinction. However, data are often lacking to objectively assess these threats. A team of German and British researchers used satellite imagery to assess the conservation status of endangered reptiles and amphibians of the Comoro archipelago in the Western Indian Ocean. The researchers used their results to point out which species are most threatened and to define priorities for future protected areas. The study was published in the open access journal ZooKeys. http://phys.org/news240753049.html Biology Thu, 17 Nov 2011 11:50:56 EST news240753049 The debate may largely be drawn along political lines, but the human role in climate change remains one of the most controversial questions in 21st century science. Writing in WIREs Climate Change Dr Kevin Trenberth, from the National Center for Atmospheric Research, argues that the evidence for anthropogenic climate change is now so clear that the burden of proof should lie with research which seeks to disprove the human role. http://phys.org/news239541021.html Space & Earth Thu, 03 Nov 2011 12:10:41 EST news239541021 Human impact on one of the world's most threatened bird species can be beneficial rather than destructive - and could even save it from extinction - according to counterintuitive new findings by the University of East Anglia (UEA). http://phys.org/news167903400.html Biology Mon, 27 Jul 2009 09:10:02 EST news167903400
