Microbes active in Colorado snows fuel tundra ecosystem

...etabolism of snow-covered microbes is an important biogeochemical "sink," or way of storing, nitrogen. "The subsequent release in spring of nitrogen from the microbes' metabolism is a major contributor to the relatively high productivity during the short growing season in the tundra," said Steven Schmidt of the Un...

New Colorado U. study shows increase in fungal metabolism under the snow

...oadens our understanding of both the diversity and biogeochemical functioning of fungi in cold environments," the researchers wrote in Science. The types of fungi and other microbes under the snow in winter and spring on Niwot Ridge are different than microorganisms found in the cold soils during the summer months,...

...en pumped out and creates favorable conditions for biogeochemical reactions that take the arsenic from a safe solid state to an unsafe liquid state, says Islam. One possible remedy that has already begun to be used is to dig deeper wells, Islam and his co-researchers say. Unsafe levels of arsenic are associated wit...

Shifts in rice farming practices in China reduce greenhouse gas methane

... researchers spent more than 10 years developing a biogeochemical model, called the Denitrification-Decomposition (DNDC) model, which would handle all the major factors relating to methane emissions from rice paddies. These factors included weather, soil properties, crop types and rotations, tillage, fertilizer and...

A drop of ocean water tells a story

...n. "Microbes like bacterioplankton are important biogeochemical agents," explained Carlson. "Over geologic time, they have played an important role in altering the chemical nature of the earths's environment, allowing for the evolution of plants and animals. Without them, we would have no oxygen to breathe, organ...
