Recording hundreds of thousands of individual uplinks from satellite transmitters fitted on penguins, albatrosses, sea lions, and other marine animals, the Wildlife Conservation Society (WCS) and BirdLife International have released the first-ever atlas of the Patagonian Sea - a globally important but poorly understood South American marine ecosystem. http://www.physorg.com/news177602301.html Biology Mon, 16 Nov 2009 14:10:01 EST news177602301 Conservation geneticists who study sea turtles have a new tool to help track this highly migratory and endangered group of marine animals: DNA barcodes. DNA barcodes are short genetic sequences that efficiently distinguish species from each other -- even if the samples from which the DNA is extracted are minute or degraded. Now, a recently published research paper by scientists from the American Museum of Natural History and the University of Canberra, among other organizations, demonstrates that this technology can be applied to all seven sea turtle species and can provide insight into the genetic structure of a widely-dispersed and ancient group of animals. http://www.physorg.com/news172161756.html Biology Mon, 14 Sep 2009 16:00:01 EST news172161756 In the first study to look at what happens over the years to the billions of pounds of plastic waste floating in the world's oceans, scientists are reporting that plastics -- reputed to be virtually indestructible -- decompose with surprising speed and release potentially toxic substances into the water. http://www.physorg.com/news169927772.html Chemistry Wed, 19 Aug 2009 19:25:39 EST news169927772 Researchers have discovered where basking sharks - the world's second largest fish - hide out for half of every year, according to a report published today in Current Biology. The discovery revises scientists' understanding of the iconic species and highlights just how little we still know about even the largest of marine animals, the researchers said. http://www.physorg.com/news160921814.html Biology Thu, 07 May 2009 13:30:52 EST news160921814 (PhysOrg.com) -- New calculations made by marine chemists from the Monterey Bay Aquarium Research Institute (MBARI) suggest that low-oxygen "dead zones" in the ocean could expand significantly over the next century. These predictions are based on the fact that, as more and more carbon dioxide dissolves from the atmosphere into the ocean, marine animals will need more oxygen to survive. http://www.physorg.com/news159200016.html Space & Earth Fri, 17 Apr 2009 15:15:09 EST news159200016 (PhysOrg.com) -- When it comes to sex, sea sponges are certainly not monogamous. But, thanks to a project based at the Heron Island Research Station, UQ researchers will uncover whether the marine animals are partaking in an underwater orgy, or if reproduction is a little harder to come by. http://www.physorg.com/news157739235.html Biology Tue, 31 Mar 2009 17:27:53 EST news157739235 (PhysOrg.com) -- Scientists said Sunday they had uncovered new marine animals in their search of previously unexplored Australian waters, along with a bizarre carnivorous sea squirt and ocean-dwelling spiders. http://www.physorg.com/news151486966.html Biology Sun, 18 Jan 2009 07:42:46 EST news151486966
