Carbon Cycling

Ultramafic lands are geologically and ecologically diverse areas that host naturally elevated concentrations of chromium (Cr), cobalt (Co), iron (Fe), manganese (Mn), nickel (Ni), and scandium (Sc). While Cr is a potential carcinogen, Co, Mn, Ni, and Sc are considered critical minerals in the United States owing to their importance in current electric battery formulations. The research conducted...

California is experiencing changes in precipitation and wildfire regimes. Longer, hotter fire seasons along with extremes in precipitation are expected to continue. Not only do these disturbances affect the productivity and resilience of ecosystems, they also directly impact human health and wellbeing. Soils hold an immense amount of our terrestrial carbon pool, and the microorganisms and minerals...

Warming and thawing of permafrost soils in the Arctic is expected to become widespread over the coming decades. Permafrost thaw changes ecosystem structure and function, affects resource availability for wildlife and society, and decreases ground stability which affects human infrastructure. Since permafrost soils contain about half of the global soil carbon (C) pool, the magnitude of C losses...
