Soil scientists determine how abandoned arable land recovers

Soil scientists from RUDN University have found that the rate of accumulation of organic carbon in wild, cultivated, and abandoned soils depends mainly on the type and composition of the soil, and, to a lesser extent, on ...

Stony corals: At the limits of adaption?

Corals fascinate amateurs and experts alike: small polyps that extract calcium carbonate from seawater and use it to build their elaborate skeletons. But climate change, with rising water temperatures and increasing ocean ...

Eight ways to halt a global food crisis

There are serious challenges to global food supply everywhere we look. Intensive use of fertilisers in the US Midwest is causing nutrients to run off into rivers and streams, degrading the water quality and causing a Connecticut-size ...

Deep sea reveals linkage between earthquake and carbon cycle

In order to understand the global carbon cycle, deep-sea exploration is essential, an international team led by geologists from Innsbruck concludes. For the first time, they succeeded in quantifying the amount of organic ...

Forest carbon stocks have been overestimated for 50 years

Basic density is widely used to compute carbon storage by trees. A formula used to calculate basic wood density has recently been corrected. Researchers estimate that the error in the initial formula resulted in an overestimation ...

Soil pores, carbon stores, and breathing microbes

Researchers at the Pacific Northwest National Laboratory (PNNL) recently studied how moisture influences soil heterotrophic respiration. That's the breathing-like process by which microbes convert dead organic carbon in the ...

Deep mantle chemistry surprise: Carbon content not uniform

Even though carbon is one of the most-abundant elements on Earth, it is actually very difficult to determine how much of it exists below the surface in Earth's interior. Analysis by Carnegie's Marion Le Voyer and Erik Hauri ...
