OVERVIEW
Untamed microorganisms grow in soil by the billions per handful. They
interact closely with plants and carry out an array of biogeochemical processes,
with consequences for water quality, atmospheric change, and plant conservation.
And yet, the diversity and assembly of these microbial communities remains a
mystery. Most
problems in community ecology can be reduced to two fundamental questions that
apply to all organisms and environments:
How does community composition affect ecosystem processes?
What mechanisms govern the distribution of organisms (populations, species, communities) in space and time?
To answer these questions, we test ecological theories that integrate local and regional processes, and deal explicitly with interactions between the organism niche and the environment. We perform both manipulative experiments and detailed spatial analyses of communities and soil properties in the field, combining a variety of approaches (i.e., ecology, microbiology, molecular biology, soil science, multivariate spatial statistics, plant biology, evolutionary biology).
Microbial communities represent unique opportunities and challenges in testing
ecological theory. Microbes can be difficult to identify and characterize,
but genomic information about microorganisms is rapidly accumulating, raising
the prospect of enriching ecology with modern molecular and bioinformatic
methods. These methods have already revealed unanticipated diversity and
unexplored, but widespread, microbial lineages present in soils. Our
challenge now is to determine how these organisms become distributed in the
environment, and what their role is in creating stable ecosystems.
Examples of ecosystem processes we study include:
recycling of nutrients and stabilization of soil organic matter through decomposition
plant nutrient uptake mediated by mycorrhizal fungi
production and consumption of methane, an important greenhouse gas.
