Melting Sea Ice Forcing Polar Bears to Swim Longer Distances, Linked to Increased Mortality of Cubs, Finds New Study

Melting Sea Ice Forcing Polar Bears to Swim Longer Distances, Linked to Increased Mortality of Cubs, Finds New Study











Polar bears like this one are having to spend more time in the Arctic water due to less summer sea ice.


Ottawa, Canada (PRWEB) July 19, 2011

Sea ice loss from climate change is causing polar bears to swim longer distances to find stable ice or to reach land, resulting in greater risk to their cubs, according to a new paper co-authored by a WWF expert.

“Climate change is pulling the sea ice out from under polar bears’ feet, forcing some to swim longer distances to find food and habitat,” said Geoff York, WWF Polar Bear Expert who is an author of the study.

“This research is the first analysis to identify a significant multi-year trend of increased long-distance swimming by polar bears. Prior research had only reported on single incidents,” said York.

U.S. Geological Survey biologist and lead author Anthony Pagano will present the study (“Long-distance swimming events by adult female polar bears in the southern Beaufort and Chukchi Seas”) on July 19 at the International Bear Association (IBA) Conference held in Ottawa, Canada.

Between 2004 and 2009 researchers collected data from 68 GPS collars deployed on adult female polar bears, in combination with satellite imagery of sea ice, to identify incidences of bears swimming more than 30 miles at a time. Researchers identified 50 long-distance swimming events during the six year period involving 20 polar bears. Swimming events ranged in distance up to 426 miles and in duration up to 12.7 days.

Eleven of the polar bears that swam long distances had young cubs at the time of collar deployment; five of those bears lost their cubs during swimming — a 45% morality rate. In contrast, only 18% of cubs died that were not compelled to swim long distances with their mother.

The final report is not yet released but the full abstract is provided below.

Key Facts


    Arctic sea ice extent has dropped to record low levels in July 2011; sea ice volume is now 47% lower than 1979 levels when satellite records began (Source: University of Washington Polar Science Center).
    The annual Arctic sea ice minimum will be reached in mid-September. September 2010 saw the third lowest sea ice extent on record. The lowest and second-lowest extents occurred in 2007 and 2008 (Source: National Snow and Data Center).
    Long-distance swimming puts polar bears at risk of drowning due to fatigue or rough seas. Like humans, polar bears can’t close off their nasal passages so they are at risk of drowning in rough water. Cubs are at even greater risk. Their smaller body size and limited body fat leaves them more prone to hypothermia, and they don’t have the energy reserves of an adult bear.
    On June 30, 2011 a federal judge upheld the George W. Bush administration decision to list the polar bear as threatened under the Endangered Species Act. In July 2011, Canada placed the polar bear on their Species at Risk list.
    Adult male polar bears were not studied because they cannot retain GPS collars because their muscular necks are larger than their heads.

Long-distance swimming events by adult female polar bears in the southern Beaufort and Chukchi seas

Abstract

Polar bears (Ursus maritimus) are dependent on sea ice for their survival and reductions in sea ice have been linked to population declines. In the southern Beaufort and Chukchi seas, the duration between melt and freeze onset has increased and summertime sea ice extent has decreased. As summer ice habitats melt in this region, polar bears that do not follow the receding pack ice may be forced to swim long distances to areas of higher sea ice concentration or to land. We used data from 68 Global Positioning System collars deployed on adult female polar bears between 2004 and 2009, in combination with satellite imagery of sea ice, to identify swimming events >50 km. During summer and autumn (June through October) we identified 50 swimming events from 20 polar bears. We found a significant increase (r2 = 0.83, P = 0.03) in the proportion of GPS collared bears that swam over the 6 years of this study, but variations in the number of collar deployments per year and improvements in collar technology over the course of the study preclude us from fully evaluating this trend. Swimming duration and distances traveled ranged from 0.7 to 12.7 days (mean: 4.0 days) and 53.7 to 687.1 km (mean: 167.3 km). Most bears swam from areas of unconsolidated sea ice to the main pack ice (mean distance: 178.1 km; n = 25). Average movement rates during swimming (1.9 km/hr) were 2.2 times higher than movement rates on sea ice >50% concentration (0.9 km/hr). We identified 6 bears whose dependent cubs survived long distance swimming events and 5 bears that may have lost their cubs as a consequence of swimming. Despite the ability of polar bears to swim long distances, this behavior places them at risk of drowning and imposes greater energy expenditure, which could have negative impacts on recruitment. Long distance swimming is likely an additional indicator of the negative effects of sea ice loss on polar bears in the southern Beaufort and Chukchi seas.

Disturbing Study Sparks New Program at Local School

Disturbing Study Sparks New Program at Local School










Beaverton, OR (PRWEB) October 9, 2006

Local martial arts school Urban Warrior Incorporated has responded to a startling new series of studies that indicate an overweight child rates his or her life as low as that of a young cancer patient. The school’s new Martial Arts Fit Kid program helps kids get healthier with a combination of martial arts, fitness and personal development training. “I read that study and it hit me that we are in a great position to help these kids,” said Scott Buendia, the school’s owner. “For one, we’ll help them lose weight, which is the most important aspect for their physical and mental health. But, let’s face it; learning martial arts greatly reduces the threat of bullies.”

According to three separate studies, overweight children are far more prone to be bullied and stressed. The results in a study of 5,749 Canadian youngsters echo data from British research and follow a U.S. study published last year in which obese children rated their quality of life as low as young cancer patients’ because of teasing and weight-related health problems.

Buendia says, “Heavy kids tend to isolate themselves because of the fear of being picked on. Then their world becomes food and TV. That makes the problem worse. We have a safe, protected environment at this school. They will not be picked on and they will gain confidence, as they get fit. That’s why we call it the Martial Arts Fit Kid Program.”

Urban Warrior Incorporated is located at 12570 SW Farmington Road, Beaverton, OR 97005 (inside the Portland Community Ballet). For information call the school at 503-548-3618 or visit their website at http://www.urbanwarriorinc.com.

NAMI Echoes Iowa State Television and Mental Health Study Findings

NAMI Echoes Iowa State Television and Mental Health Study Findings











Arlington, VA (PRWEB) May 2, 2008

The National Alliance on Mental Illness’s Bob Carolla responded to a recent Iowa State University influence of television on mental health treatment study, “The Iowa State study is right. Television’s portrayal of people who live with mental illnesses and people who work in mental health professions too often reflects negative stereotypes. It makes stigma and discrimination worse. Hollywood sometimes gets it right, but only when producers, directors and writers take the time to do their homework. There are basic standards of accuracy, fairness and compassion that still produce good entertainment.”

Bob Carolla oversees NAMI’s StigmaBuster program which seeks to address outdated, outrageous, offensive portrayals or language about persons with mental illness.

NMI Study Finds that Consumers Seek Specific Health Claims in Their Food and Nutritional Supplements

NMI Study Finds that Consumers Seek Specific Health Claims in Their Food and Nutritional Supplements










Harleysville, PA (PRWEB) June 7, 2006

The Natural Marketing Institute (NMI), the leading provider of strategic consulting, consumer insights and market research services for the health, wellness and sustainability marketplace, today expanded on one of the key trends it has identified as having a significant impact in 2006.

According to NMI’s Health & Wellness Trends Database™, 2006 will see the continued propagation of specific nutrient platform drivers across food/beverages and nutritional supplements. The desire for specificity is evident as 57% of all U.S. consumers indicate they are looking for foods that have a specific health claim and about half prefer to buy vitamins/minerals/herbals/dietary supplements that have a specific health claim. Use of functional foods and condition-specific supplements are also on the rise, showing 5-year compound annual growth rates of 17% and 16% respectively.

“This desire for health claims is evident across many consumer packaged goods. For example, with over 29 million people (adults and children) suffering from food allergies, allergen-free foods will continue to experience solid growth. Introductions of gluten-free foods alone have shown a 50% compound annual growth over the past six years and generate U.S. retail sales in excess of $ 400 million. Another nutrient to watch in 2006 is probiotics, which has shown annual awareness increases of 27% since 2002,” according to NMI President Maryellen Molyneaux.

Manufacturers are integrating specific nutrients into foods and supplements related to certain health conditions such as heart disease and digestive health. These nutrients include fish oil, omega 3, lutein, lycopene, probiotics plant sterols, among others. “While consumers may lack understanding of the specific health benefits of some nutrients, savvy manufacturers and marketers will use this opportunity for continued education to raise the value of their nutrient-rich products in the eyes of the consumers,” says Molyneaux.

NMI is a strategic consulting, market research, and business development company specializing in the health, wellness, and sustainable marketplace. For more information on NMI’s trend reports, proprietary databases and other services, visit NMI’s web site at http://www.NMIsolutions.com.
