DESCRIPTION:Dr. Caitlin Hicks Pries\; Assistant professor\, Dartmouth Colle
 ge presents: Digging Deeper to Understand the How Soils Respond to Climate
  Change.\n\nSoils store over three times as much carbon as our atmosphere\
 , and as soils warm\, they have the potential to become a large positive f
 eedback to climate change. Over half of this organic carbon is stored in d
 eeper soils\, but most climate change experiments have only focused on sur
 face soils. Here I explore the vulnerability of deep (>20 cm) soil carbon 
 to climate change through a series of experiments in locations ranging fro
 m hardwood temperate forests to tropical Hawaii to agricultural fields. I 
 have found that the response of deep soils to climate change varies greatl
 y across these ecosystems and is likely dependent on the availability of s
 oil carbon to the microbes that consume it. This conclusion is supported b
 y a global meta-analysis of soil radiocarbon data among different soil fra
 ctions. Overall\, the magnitude of soil’s positive feedback to climate cha
 nge may be limited by the amount of easily consumed particulate carbon. Ho
 wever\, the effect of changing precipitation regimes on soil carbon remain
 s an open question.\n\nCaitlin Hicks Pries is an ecosystem ecologist/bioge
 ochemist researching how terrestrial ecosystems and soils respond to clima
 te change and how soils can be managed to help mitigate climate change. Ca
 itlin is a graduate of Middlebury College. She received a MSc in Soil Scie
 nce and a PhD in Biology at the University of Florida and then completed a
  postdoc at the Lawrence Berkeley National Laboratory in Berkeley\, Califo
 rnia. Caitlin is currently an Assistant Professor at Dartmouth College whe
 re she teaches classes in Ecology and Global Change Biology. Caitlin’s res
 earch spans ecosystems from mangroves to tundra\, grasslands to farmland\,
  and tropical to temperate forests. She has won early career awards from t
 he Soil Science Society of America and the Biogeosciences Division of the 
 European Geosciences Union. She is an active contributor to the Internatio
 nal Soil Radiocarbon Database working group and a member of the terrestria
 l biogeochemistry advising committee of the National Ecological Observator
 y Network.\n
