Cells in the Cold (CECO)
A delicate network of cold-adapted microbial cells controls greenhouse gas (GHG) emissions from Arctic permafrost ecosystems, one of the largest potential methane (CH4) sources in the warming Arctic. Because Arctic ecosystems are central to the current climate change impacts, microbial processes in these environments are particularly important in a global context.
CECO is dedicated to expose the structure and evolution of cold-adapted carbon-cycling microbial networks and to reveal regulatory mechanisms of these networks that underlie climatic regulation of anaerobic and aerobic GHG emissions from Arctic terrestrial ecosystems.
Combining advanced laboratory and field equipment with cutting-edge methods in microbial ecology, including metagenomics, metatranscriptomics, stable isotope probing, and sophisticated aerobic and anaerobic cultivation techniques, we focus on four main subjects within CECO.
