                                      As arctic temperatures rise, we expect to see dramatic changes due to thawing permafrost soils. Permafrost stores half the total amount of carbon (C) found in soils globally, and twice as much C as is found in the atmosphere. As permafrost thaws, the stored C becomes vulnerable to loss because low temperatures no longer limit […]

                                        Taylor is interested in Arctic permafrost carbon dynamics and how high latitude biogeochemistry and ecosystem function changes in response to rapid climate change. To quantify these processes, she uses carbon flux measurements and isotope geochemistry within long-term experimental manipulations in Alaskan discontinuous permafrost to develop a mechanistic understanding of ecosystem sinks and sources and how […]
