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) -- Tiny microscopic creatures commonly known as water bears (also called Tardigrades), along with a few other life forms, will be sent to the Martian moon Phobos to test whether organisms can survive for long periods of time in deep space. The mission, called the Living Interplanetary Flight Experiment (LIFE), was originally going to be launched earlier this month, but it has been delayed due to safety and technical issues. Currently, the scientists hope to launch the specimens on the Russian Phobos-Grunt spacecraft in 2011, the next time that the orbits of Earth and Mars offer a launch window. http://www.physorg.com/news174659888.html Space & Earth Tue, 13 Oct 2009 13:39:08 EST news174659888 The discovery of brown (grizzly) bears feeding on migrating broad whitefish in a stream in Mackenzie Delta region of the Northwest Territories has researchers advising increased care in petroleum extraction and infrastructure development within the area. http://www.physorg.com/news172842131.html Biology Tue, 22 Sep 2009 12:43:41 EST news172842131 (AP) -- A federal judge in Montana restored protections Monday for an estimated 600 grizzly bears in and around Yellowstone National Park, citing in part a decline in their food supply caused by climate change. http://www.physorg.com/news172770921.html Biology Mon, 21 Sep 2009 16:56:40 EST news172770921 "The Arctic as we know it may soon be a thing of the past," says Eric Post, associate professor of biology at Penn State University. Post leads a large, international team that carried out ecosystem-wide studies of the biological response to Arctic warming during the fourth International Polar Year, which ended in 2008. The team's results will be reported on 11 September 2009 in the journal Science. http://www.physorg.com/news171811398.html Space & Earth Thu, 10 Sep 2009 15:10:03 EST news171811398 A new approach to tracking polar bears, developed by Queen's University researchers, will shed more light on the potentially endangered Arctic animal and help boost the economy of Canada's north. http://www.physorg.com/news164555200.html Biology Thu, 18 Jun 2009 15:10:01 EST news164555200 As the human population continues to grow and resource demands soar, biodiversity conservation has never been more critical said University of New Mexico Biology Department postdoctoral researchers Ana Davidson and Marcus Hamilton in a paper released today in the latest issue of the Proceedings of the National Academy of Sciences (PNAS). http://www.physorg.com/news164382956.html Biology Tue, 16 Jun 2009 15:40:01 EST news164382956 (PhysOrg.com) -- Some Michigan mammal species are rapidly expanding their ranges northward, apparently in response to climate change, a new study shows. In the process, these historically southern species are replacing their northern counterparts. http://www.physorg.com/news161361652.html Biology Tue, 12 May 2009 15:41:19 EST news161361652 (PhysOrg.com) -- In the U.S., there is a tradition followed by outgoing presidents: Enact as many new policies as possible -- especially if you think that the incoming president would disapprove. This practice has been used by presidents of both political parties with increasing fervor since Ronald Reagan. And President George W. Bush was no exception. In the months leading up to the inauguration of Barack Obama, Bush enacted a number of policies that stripped away a number of environmental protections. And, almost since he has taken the oath of office, President Obama's team has been working to reverse these policies. http://www.physorg.com/news160400988.html Space & Earth Fri, 01 May 2009 12:50:22 EST news160400988 The situation of bears in the Iberian Peninsula is critical. Researchers from the University of Oviedo (UO) and the Superior Council of Scientific Research (SCSR) have performed a genetic identification based on the analysis of stools and hair of brown bears (Ursus arctos) from the Cantabrian mountain range, gathered between 2004 and 2006. http://www.physorg.com/news160232757.html Biology Wed, 29 Apr 2009 14:07:26 EST news160232757 (AP) -- The bear cub could be heard but remained unseen among the barren trees and dried leaves blanketing the forest floor. http://www.physorg.com/news159864719.html Biology Sat, 25 Apr 2009 07:53:03 EST news159864719 By comparing the craniodental morphology of modern bear species to that of two extinct species, researchers from the University of Málaga, Spain, have discovered that the expired plantigrades were not so different from their current counterparts. The cave bear, regarded as the great herbivore of the carnivores, was actually more omnivorous than first thought. The short-faced bear, a hypercarnivore, also ate plants depending on their availability. The work offers key insights into the evolution of the carnivore niches during the Ice Age. http://www.physorg.com/news158489644.html Biology Thu, 09 Apr 2009 09:54:26 EST news158489644 One by one, 13 sick and traumatised Asian black bears squeezed into tiny cages are pulled from a truck, a lifetime of agonising torture now over. http://www.physorg.com/news155992932.html Biology Wed, 11 Mar 2009 12:22:42 EST news155992932 As polar bears adapt to a warming Arctic -a frozen seascape that cleaves earlier each spring -they may find relief in an unlikely source: snow goose eggs. New calculations show that changes in the timing of sea-ice breakup and of snow goose nesting near the western Hudson Bay could provide at least some polar bears with an alternative source of food. This new analysis appears in Polar Biology. http://www.physorg.com/news148564165.html Biology Mon, 15 Dec 2008 11:49:25 EST news148564165 (PhysOrg.com) -- Enormous cave bears, Ursus spelaeus, that once inhabited a large swathe of Europe, from Spain to the Urals, died out 27,800 years ago, around 13 millennia earlier than was previously believed, scientists have reported. http://www.physorg.com/news146898316.html Other Sciences Wed, 26 Nov 2008 05:05:16 EST news146898316 Black bears that live around urban areas weigh more, get pregnant at a younger age, and are more likely to die violent deaths, according to a study by the Wildlife Conservation Society (WCS). http://www.physorg.com/news141996872.html Biology Tue, 30 Sep 2008 12:34:32 EST news141996872 The tooth-protecting sugar substitute xylitol has been incorporated into gummy bears to produce a sweet snack that may prevent dental problems. Research published today in the open access journal BMC Oral Health describes how giving children four of the xylitol bears three times a day during school hours results in a decrease in the plaque bacteria that cause tooth decay. http://www.physorg.com/news136181023.html Medicine & Health Fri, 25 Jul 2008 05:03:43 EST news136181023
