Latest Nitrogen cycle Stories
When fire burns down a forest, nitrate levels go up, and the effects are persistent.
Within the sludge of wastewater treatment plants is an invisible world teeming with microbes.
Study suggests pollution reductions could help restoration efforts.
In the microbial world, an unusual marine microorganism appears to have ditched several major metabolic pathways, leaving it with a remarkably reduced set of genes.
Scientists including researchers from the National Oceanography Centre, Southampton and the University of Essex have discovered that interactions between iron supply, transported through the atmosphere from deserts, and large-scale oceanic circulation control the availability of a crucial nutrient, nitrogen, in the Atlantic.
A team of researchers at the University of British Columbia, along with colleagues at the US Dept. of Energy Joint Genome Institute, has mapped the genome of a microbe that is silently helping to shape the ecology of oxygen-minimum areas in the ocean known as dead zones.
Scientists have identified an unexpected metabolic ability in a symbiotic community of deep-sea microorganisms. It may help solve a lingering mystery about the world's nitrogen cycle.
It's not every day you find clues to the planet's inner workings in aquarium scum. But that's what happened a few years ago when University of Washington researchers cultured a tiny organism from the bottom of a Seattle Aquarium tank and found it can digest ammonia, a key environmental function.
Trichodesmium has important role in nitrogen cycle and carbon sequestration.
After more than a decade of inquiry, a Princeton-led team of scientists has turned the tables on a long-standing controversy to re-establish an old truth about nitrogen mixing in the oceans.
