The coming period of economic contraction and resource shortage will cause the entire world to reject liberalism and turn back towards conservatism, according to a new scientific text published by Federalist Publications, examining the biological forces which produce ideological shifts in populations. If this book's thesis is true, all other factors, from demographic projections to cultural evolution will prove powerless to forestall a new conservative political revival. (PRWEB) July...

UV Light Used As A New Tool To Detect White-Nose Syndrome In Bats
2014-05-30 12:22:49

Brett Smith for redOrbit.com - Your Universe Online According to a new study in the Journal of Wildlife Diseases, biologists looking to identify bats with the deadly white-nose syndrome have a new, non-invasive tool – ultraviolet light. The study authors found that when they directed UV light at the wings of bats with WNS, microscopic skin lesions on the animals fluoresce with a distinctive orange-yellow color. “When we first saw this fluorescence of a bat wing in a cave, we knew...

A Refined Technique On Sampling Bat Population Sizes Developed
2014-05-29 14:25:11

Brett Smith for redOrbit.com - Your Universe Online For years, researchers have been using acoustic monitoring technology to assess the bat population in specific areas. Researchers conducting a new study around Form Drum in upstate New York have now developed a refined method on this non-invasive sampling technique. Published in the Journal of Ecology and the Natural Environment, the new study concluded that transect sampling — installing a row of detectors for a week, then moving...

SANTA BARBARA, Calif., April 21, 2014 /PRNewswire-USNewswire/ -- A devastating oil spill off the coast of Santa Barbara inspired Wisconsin Senator Gaylord Nelson to create the first Earth Day in 1970. Twenty million Americans participated as Nelson and conservationists across the country noted that "every environmental problem is a population problem." Since that first Earth Day, the U.S. population has soared from 203 million to 318 million, due mostly to immigration. Today, a Santa...

Increase in Concentration of Newly Identified Replikin Beetoxingene Preceded Current CCD Outbreaks; Beetoxingene Sequences are CCD Blocker and Vaccine Candidates LONDON, March 21, 2014 /PRNewswire/ -- Bee Colony Collapse Disorder (CCD) is increasing with unknown cause(s). There is no effective treatment or prevention of CCD. Increasing loss of bee colonies since 2005 is resulting in the loss of bee pollination which poses a threat to food production worldwide....

Researchers Reveal New Clues Of Bat Killer’s Path
2014-01-30 11:08:17

The University of Akron As North American bats face a death toll approaching 7 million, University of Akron scientists reveal new clues about their killer, White Nose Syndrome, or WNS. The UA researchers reveal that the deadly WNS fungus can likely survive in caves with or without the presence of bats and threatens the regional extinction of North American bats. This discovery casts a gloomy forecast for the curious flying mammals, which serve as critical food plant pollinators and...

Population Growth Was Slow In The US During 2013
2014-01-01 05:37:00

Ranjini Raghunath for redOrbit.com - Your Universe Online The U.S. population grew by a mere 0.72 percent in the last year, the lowest since the Great Depression in 1937, according to new figures released by the Census Bureau on Monday. On New Year’s Day 2014, the population of the U.S. will top off at roughly 3.2 million - an increase of 2.2 million from New Year's Day in 2013. Although the U.S. growth rate is lower than the global growth rate of 1.1 percent, it is still higher than...

Deadly Fungus Cause Of Frog Declines In The Andes
2013-12-13 07:25:23

San Francisco State University Amphibians at high elevations can tolerate temperature changes, but susceptible to deadly fungus A deadly fungus, and not climate change as is widely believed, is the primary culprit behind the rapid decline of frog populations in the Andes mountains, according to a new study published today in the journal Conservation Biology. Frogs living at higher elevations can tolerate increasing temperatures, researchers found, but their habitats fall within the...

Survey Finds Frog Abnormalities Are Rare
2013-11-20 13:45:34

University of California, Davis A 10-year study shows some good news for frogs and toads on national wildlife refuges. The rate of abnormalities such as shortened or missing legs was less than 2 percent overall — indicating that the malformations first reported in the mid-1990s were rarer than feared. But much higher rates were found in local "hotspots," suggesting that where these problems occur they have local causes. The results were published Nov. 18 in the journal PLOS ONE. "We...

Bat White Nose Fungus Is Rubust
2013-10-25 15:38:50

Brett Smith for redOrbit.com - Your Universe Online A fungus has been decimating bat colonies for at least the last seven years, infecting bats during their winter hibernation, leaving them weak and vulnerable to starvation and secondary infections. Bats infected with Pseudogymnoascus (Geomyces) destructans often have a distinctive white fungal growth around their muzzle, a sign of what is commonly referred to as white-nose syndrome. In a study published earlier this week by the journal...
