    How do historical climate conditions shape soil microbes' contemporary responses to environmental variation? The Hawkes lab used multiple experimental approaches to address this question, and our results have just been published in PNAS.

  • 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.
