Earth's life support systems discussed

In the search for life on Mars or any planet, there is much more than the presence of carbon and oxygen to consider. Using Earth's biogeochemical cycles as a reference point, elements like nitrogen, iron and sulfur are just ...

How many lakes are there, and how big are they?

Because of the important role lakes play in regional and local biogeochemical cycling, including carbon storage and emissions, scientists need to know how many lakes of various sizes exist. However, determining the size distribution ...

Subsurface discovery sprouts a new branch on the tree of life

Bacteria are enigmatic by nature, minuscule but staggeringly—sometimes alarmingly—ubiquitous. As critical drivers of everything from global biogeochemical cycles to million dollar industries, they are the little cogs ...

Microbial changes regulate function of entire ecosystems

A major question in ecology has centered on the role of microbes in regulating ecosystem function. Now, in research published ahead of print in the journal Applied and Environmental Microbiology, Brajesh Singh of the University ...

Biogeochemistry at the core of global environmental solutions

If society wants to address big picture environmental problems, like global climate change, acid rain, and coastal dead zones, we need to pay closer attention to the Earth's coupled biogeochemical cycles. So reports a special ...
