The prized white marlin, sought by anglers in million dollar prize tournaments and captured incidentally in commercial fisheries, is among the most overfished marine species under international management and the subject of contentious debate on how to best achieve its recovery. http://www.physorg.com/news179651530.html Biology Thu, 10 Dec 2009 07:14:30 EST news179651530 The population of brown bears (Ursus arctos) in France is now so small that the species might become extinct in the near future. However, there is new hope in the form of new research published October 28 in the open-access, peer-reviewed journal PLoS ONE, which suggests that relocating new bears doesn't just boost the population size but can also reverse some of the causes of the population decline. http://www.physorg.com/news175896460.html Biology Tue, 27 Oct 2009 21:30:03 EST news175896460 (PhysOrg.com) -- The first century BC in Italy was culturally a brilliant age, unequaled by any other period in Roman history. It was a time of Cicero, Caesar, Vergil, Horace and many other major literary figures of the Antiquity. http://www.physorg.com/news173975496.html Other Sciences Mon, 05 Oct 2009 15:33:43 EST news173975496 Genetic evidence is revealing that human populations began to expand in size in Africa during the Late Stone Age approximately 40,000 years ago. A research team led by Michael F. Hammer (Arizona Research Laboratory's Division of Biotechnology at the University of Arizona) found that sub-Saharan populations increased in size well before the development of agriculture. http://www.physorg.com/news168072172.html Biology Wed, 29 Jul 2009 07:43:30 EST news168072172 Southern Elephant seals responded rapidly to climate and habitat change and established a new breeding site thousands of kilometres from existing breeding grounds, according to new research. http://www.physorg.com/news166425287.html Biology Fri, 10 Jul 2009 06:30:01 EST news166425287 Increasing population density, rather than boosts in human brain power, appears to have catalysed the emergence of modern human behaviour, according to a new study by UCL (University College London) scientists published in the journal Science. High population density leads to greater exchange of ideas and skills and prevents the loss of new innovations. It is this skill maintenance, combined with a greater probability of useful innovations, that led to modern human behaviour appearing at different times in different parts of the world. http://www.physorg.com/news163344562.html Other Sciences Thu, 04 Jun 2009 14:29:59 EST news163344562 Many of Washington State's sea otters are exposed to the same pathogens responsible for causing disease in marine mammal populations in other parts of the country, according to a study published by researchers from NOAA's Olympic Coast National Marine Sanctuary, the U.S. Fish and Wildlife Service and their partners. http://www.physorg.com/news160833458.html Biology Wed, 06 May 2009 13:04:06 EST news160833458 Declining numbers of a shorebird called the red knot have been linked to bait use of horseshoe crabs. http://www.physorg.com/news154106494.html Biology Tue, 17 Feb 2009 15:22:20 EST news154106494 (PhysOrg.com) -- In general, population extinction is a natural process. For one reason or another, an estimated 99.9% of all species that have lived on Earth are now extinct. However, the reasons for a species going extinct are complex, varied, and changing. Ever since the human population began dispersing throughout the Earth 100,000 years ago, the extinction rate has increased dramatically - as much as 1,000 times, by some estimates - putting us in the midst of a modern extinction called the Holocene extinction event. http://www.physorg.com/news151059872.html Physics Tue, 13 Jan 2009 09:04:32 EST news151059872 The Drosophila simulans species complex continues to serve as an important model system for the study of new species formation. The complex is comprised of the cosmopolitan species, D. simulans, and two island endemics, D. mauritiana and D. sechellia. A substantial amount of effort has gone into reconstructing the natural history of the complex, in part to infer the context in which functional divergence among the species has arisen. In this regard, a key parameter to be estimated is the initial isolation time (t) of each island species. http://www.physorg.com/news133619677.html Medicine & Health Wed, 25 Jun 2008 13:34:37 EST news133619677
