                                          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 […]

That’s one of the questions that Rachel Rubin is looking to answer with her PhD studies in the Hungate Lab at Ecoss. In order to determine how climate change will interact with grassland restoration, Rachel […]

She uses a variety of quantitative approaches, such as data assimilation, meta-analyses and multivariate analyses. She works in a broad array of ecosystems, from deserts to grasslands to forests to the poles, and at different scales, from the […]

To do this, he often use meta-analytic techniques to synthesize findings in his field of research. Van Groenigen also studies the role of soil microbes in C and N cycling processes, using techniques […]
