      The Waring lab is excited to welcome two new graduate students: Savannah Adkins and Sam Willard.

      August 6 2019

      The Waring lab has received two new research grants: one from the Department of Energy Terrestrial Ecosystem Science program to investigate microbial roles in soil carbon cycling, and one from the NSF Macrosystems program to study carbon-nitrogen cycle interactions with Colin Averill and Samantha Weintraub. We are very excited to launch these new projects!

      Congratulations to Jessica, who just received two grants to support her research on Costa Rican canopy soils - a Sigma Xi Grant-in-aid of Research and an Organization for Tropical Studies Research Fellowship. Felicidades!

      January 1 2019

      The lab welcomes Guopeng Liang, a PhD student interested in climatic controls on soil carbon cycling in drylands.

      September 20 2018

      Kenny's first post-doc paper, examining climatic and edaphic controls on dryland soil carbon stocks, is published in Ecosystems. Congratulations Kenny!

      Interested in joining the Waring lab? I am recruiting a PhD student to start in Fall 2019. Learn more about our work at ESA (and check out our organized oral session on mechanisms of soil organic matter formation)! Contact me at [email protected] to set up a meeting.

      June 2018

      The Waring Lab field season is in full swing: Karen and Bonnie just returned from Alaska to start an incubation experiment with high-latitude wetland soils. Meanwhile, Jess is wrapping up her canopy soils surveys in Monteverde and preparing to visit the Barva Transect near La Selva Biological Station. Check out the photos from both sites below!

      May 10-13 2018

      The Waring lab hosted a technical tree climbing course for canopy researchers, taught by expert arborist Tyler Zuniga, ahead of Jessica's first field season studying canopy soils in Costa Rica.

      April 16 2018

      The Waring lab welcomes Karen Foley, a new Master's student who will be working on carbon-climate feedbacks in high-latitude wetlands. We are also excited to have undergraduate researchers Zach Anthony and Lizzy Lasley on board for fieldwork this summer. Welcome everyone!

      February 26 2018

      The Waring lab spent the weekend in Moab, UT, sampling soils from the USGS long-term ecosystem warming experiment. Of course, we also found time to do some hiking and see some of the amazing petroglyphs in the area. Check out the lab photos in the gallery below! (All the nice ones were taken by Kenny.)

      I have started my position at Utah State! I am recruiting graduate students, undergraduate students, and post-docs. Contact me at [email protected] for more information.

    • Research

      In order to mitigate the effects of global climate change on the environment, we need a predictive understanding of the ecological interactions that drive biogeochemical processes. To that end, we study how plant and soil microbial communities mediate carbon cycling in a diverse array of terrestrial ecosystems .

      The role of soil microbes in the stabilization and cycling of soil carbon

      Soil is one of the most chemically complex substances on earth, and represents the largest terrestrial carbon pool. One of our major objectives is to understand how microbial physiology and community structure influence the formation and turnover of soil C along broad environmental gradients.

      Tropical forest responses to climate change

      Tropical forests exchange more carbon with the atmosphere than any other biome, and are experiencing rapid changes in climate and land use. We use a combination of observational and manipulative experiments to understand how the composition and function of these forests will change under future climates.

      Plant-mycorrhizal interactions

      Mycorrhizal fungi are ubiquitous root symbionts that play a major role in plant nutrient acquisition and influence the cycling of soil carbon. Our goal is to understand how soil nutrient stoichiometry influences the ecological relationship between plant and fungus in both arbuscular and ectomycorrhizal systems.
