The findings, published in this week's issue of Science, conclude that food-web stability is enhanced when many diverse predator-prey links connect high and intermediate trophic levels. The computations also reveal that small ecosystems follow other rules than large ecosystems: differences in the strength of predator-prey links increase the stability of small webs, but destabilize larger webs. http://www.physorg.com/news168787660.html Biology Thu, 06 Aug 2009 15:20:01 EST news168787660 University of Queensland Master of Science student Maren Dammann is aiming to uncover what makes a koala's wish list when it comes to choosing a place to live. http://www.physorg.com/news155941528.html Biology Tue, 10 Mar 2009 22:06:14 EST news155941528 (PhysOrg.com) -- In the rogues' gallery of microscopic infectious agents, the prion is the toughest hombre in town. http://www.physorg.com/news151169843.html Biology Wed, 14 Jan 2009 15:37:23 EST news151169843 Barry Roberts wants to help build a better rocket…one that can fly despite record low temperatures, one that hail and rain can`t stop. http://www.physorg.com/news134314693.html Space & Earth Thu, 03 Jul 2008 14:38:13 EST news134314693
