Amphibians in losing race with environmental change

...ns lay their eggs in shallow, open water in direct sunlight to provide a more oxygenated environment, increase growth rate of larvae and reduce predation. But the increased levels of UV-B radiation in today's sunlight, due to erosion of the Earth's ozone layer, is causing mutations, impaired immune systems an...

Alien plants attack using 'resource conservation' as weapon, researchers say

... into the soil to lock up nutrients or by blocking sunlight with tarps. But these experiments had relatively limited success. "Our results can maybe explain why that method didn't work for all the invasive species," Funk said. Current techniques for fighting invasive species typically involve early detectio...

Einstein researchers' discover 'radiation-eating' fungi

...tery. "Just as the pigment chlorophyll converts sunlight into chemical energy that allows green plants to live and grow, our research suggests that melanin can use a different portion of the electromagnetic spectrumionizing radiationto benefit the fungi containing it," says Dr. Dadachova. The research be...

Plants that produce more vitamin C may result from UCLA-Dartmouth discovery

... years ago, plants devised an efficient way to get sunlight to make sugar from carbon dioxide that produced oxygen as a waste product; that waste product probably killed off most of all living species at that time," Clarke said. "The only organisms that survived developed defenses against it, and one of the b...

Washington University in St. Louis to invest $55 million for renewable energy research

...ria represent power potential because they capture sunlight and then carry out a variety of biochemical processes. One metabolic process - the clean production of biodiesel and liquid alcohol - is a high priority for alternative fuels. Cyanobacteria also have the potential to produce cheap and plentiful hydro...

Envisat captures first image of Sargassum from space

Accurately monitoring chlorophyll from space, therefore, provides a valuable tool for modelling primary productivi...

Lack of sun does not explain low vitamin D in elderly who are overweight

... if low vitamin D stores are not attributed to low sunlight exposure in this population, it suggests that we should explore other possibilities, says Harris. The most likely explanation seems to be that vitamin D is sequestered in fat tissue, reducing its entry into the blood....

The likely result is that more vines will grow on existing trees, and compete directly with tree seedlings, Allen said. A steady increase in vine n...

Climate change isolates Rocky Mountain butterflies
