ANN ARBOR, Mich.— North American forests appear to have a greater capacity to soak up heat-trapping carbon dioxide gas than researchers had previously anticipated.
As a result, they could help slow the pace of human-caused climate warming more than most scientists had thought, a U-M ecologist and his colleagues have concluded. (more…)
*Berkeley Lab scientists decipher immune system for plants beneath our feet*
Those vegetables you had for dinner may have once been protected by an immune system akin to the one that helps you fight disease. Scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the Netherland’s Wageningen University found that plants rely on a complex community of soil microbes to defend themselves against pathogens, much the way mammals harbor a raft of microbes to avoid infections.
The scientists deciphered, for the first time, the group of microbes that enables a patch of soil to suppress a plant-killing pathogen. Previous research on the phenomenon of disease-suppressive soil had identified one or two pathogen-fighting microbes at work. (more…)
Research by the University of Exeter has revealed that ants have a big impact on their local environment as a result of their activity as ‘ecosystem engineers’ and predators.
The study, published in the Journal of Animal Ecology, found that ants have two distinct effects on their local environment. (more…)
