Do rising temperatures matter?

Relationships between the environment and population dynamics in ecology have a long history of polarized debates usually involving two alternative and opposite explanations that exclude each other. One of the best known examples is found in the early question of what regulates populations and the role of extrinsic vs. intrinsic factors, opposing the importance of the environment (or density-in...

Stability of peatland carbon to rising temperatures

Peatlands contain one-third of soil carbon (C), mostly buried in deep, saturated anoxic zones (catotelm). The response of catotelm C to climate forcing is uncertain, because prior experiments have focused on surface warming. We show that deep peat heating of a 2 m-thick peat column results in an exponential increase in CH4 emissions. However, this response is due solely to surface processes and...
