Ecologists have at last worked out a way of using recordings of birdsong to accurately measure the size of bird populations. This is the first time sound recordings from a microphone array have been translated into accurate estimates of bird species' populations. Because the new technique, reported in the British Ecological Society's Journal of Applied Ecology, will also work with whale song, it could lead to a major advance in our ability to monitor whale and dolphin numbers. http://www.physorg.com/news178525475.html Biology Fri, 27 Nov 2009 06:25:08 EST news178525475 (PhysOrg.com) -- Using sheep to control leafy spurge works best if it's done in the spring every year, according to an Agricultural Research Service (ARS) study. http://www.physorg.com/news173542061.html Biology Wed, 30 Sep 2009 15:08:03 EST news173542061 Scientists from the Universities of Exeter and Plymouth are today calling for urgent research to understand the impact of renewable energy developments on marine life. The study, now published in the Journal of Applied Ecology, highlights potential environmental benefits and threats resulting from marine renewable energy, such as off-shore wind farms and wave and tidal energy conversion devices. http://www.physorg.com/news172401061.html Space & Earth Thu, 17 Sep 2009 10:30:03 EST news172401061 Without at least a temporary reprieve from hunting, the world's largest species of fruit bat, Pteropus vampyrus or the "large flying fox", could be driven to extinction in Peninsular Malaysia at the current hunting rate, scientists have warned. Writing in the new issue of the British Ecological Society's Journal of Applied Ecology, they say around 22,000 flying foxes are legally hunted (in addition to those illegally hunted) each year in Peninsular Malaysia, a level of hunting that is unsustainable based on their estimates of the number of bats in the country. http://www.physorg.com/news170447435.html Biology Tue, 25 Aug 2009 19:40:02 EST news170447435 Conserving Australia's most endangered snake might mean lighting more bush fires, ecologists have proposed. http://www.physorg.com/news157105645.html Biology Tue, 24 Mar 2009 09:28:37 EST news157105645 Last winter, government agencies killed one third of Yellowstone National Park's bison herd due to concerns about the possible spread of a livestock disease to cattle that graze in areas around the park. Such drastic measures may be unnecessary, however, according to researchers who have assessed the risk of disease transmission from Yellowstone bison to cattle. http://www.physorg.com/news150991706.html Biology Mon, 12 Jan 2009 14:08:26 EST news150991706 Removing an invasive species from sub-Antarctic Macquarie Island, a World Heritage Site, has caused environmental devastation that will cost more than A$24 million to remedy, ecologists have revealed. Writing in the new issue of the British Ecological Society's Journal of Applied Ecology, they warn that conservation agencies worldwide must learn important lessons from what happened on Macquarie Island. http://www.physorg.com/news150989903.html Biology Mon, 12 Jan 2009 13:38:23 EST news150989903
