Antarctica's Extreme Salt-Loving Microbes Swap DNA
2013-10-01 00:26:00| Climate Ark Climate Change & Global Warming Newsfeed
Live Science: Microbes living in Antarctica's saltiest lake swap huge chunks of genetic material as a means of surviving their harsh environment, a new study finds. The single-celled organisms, called haloarchaea for their salt-loving ways, are biologically distinct from bacteria, algae and other tiny creatures that can thrive in extreme settings. Their Antarctic home is a deep lake in the Vestfold Hills severed from the ocean more than 3,000 years ago. Appropriately named Deep Lake, the basin sits 50 meters...

Microbes Living in Deep Ocean Absorb Carbon Using Chemical Energy
2013-09-06 17:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: They may not absorb enough carbon to curtail global warming, but the microbes that call the deep ocean home absorb enough of it to merit further study, according to a paper published in the International Society of Microbial Ecology (ISME) Journal. Lead author of the paper Tim Mattes, an associate professor of civil and environmental engineering at the University Iowa, explained that while most are familiar with the role of trees and grass in absorbing carbon from the air, organisms such as bacteria...

Microbes will joust for survival in Earth's warming climate
2013-07-05 02:49:00| Climate Ark Climate Change & Global Warming Newsfeed
LA Times: The meek shall inherit the Earth, and that may not be a good thing, if the meek are cyanobacteria. It turns out that the ancient microbes lowest on Earth's food chain are sensitive sorts. Familiar strains of these organisms that provide "biological services" essential to complex life are about to lose the competition for a viable niche in a world turned warmer and more carbon-rich, according to two new studies. And the strains poised to dominate in the desert and ocean remain mysterious and largely...

Climate Change Altering Oceanic Food Chain by Allowing Certain Microbes to Survive
2013-07-03 17:32:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Climate change is favoring certain strains of bacteria leading to a drastic change in microbial life in the ocean, a new study has found. Researchers say that change in microbial activity in the ocean leads to changes in the entire food chain. The oceans have a fine balance of life that has taken millions of years to develop. A previous study had found that rising temperatures along with a high influx of nitrogen was disrupting the food chain in the ocean. In the present study, researchers...
Measuring microbes makes wetland health monitoring more affordable, says researcher
2013-04-10 01:42:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Wetlands serve as Earth's kidneys. They filter and clean people's water supplies while serving as important habitat for many species, including iconic species like cattails, cranes and alligators. Conventional ecosystem health assessments have focused on populations of these larger species. However, the tiny, unseen creatures in the wetlands provided crucial indicators of the ecosystems' health in a study by University of Missouri Associate Professor of Engineering Zhiqiang Hu and his team. Using...
