Broadly, my group is interested in the biotic and abiotic contexts that shape the composition of ecological communities and the functioning of ecosystems. We use a combination of microcosm experiments, manipulative field experiments, and global-scale observational experiments to explore: 1) the drivers of biodiversity at local and global scales, 2) how fine-scale changes in plant-microbiomes scale to influence community interactions and ecosystem function, and 3) how global change will re-shape interactions among microbial communities, plant communities, plant microbiomes, and ecosystem function. We are conducting most of this work in coastal dune ecosystems along the gulf coast.
What are the drivers of biodiversity at local and global scales?
Since the time of Wallace and Darwin, global biodiversity patterns have fascinated scientists; however, the most diverse area in the world, the soil, still remains a mystery. To understand the biodiversity and abundance patterns of belowground communities globally, as well as the factors that drive them, we implore macroecological and computational approaches to synthesize across a variety of soil bacterial and fungal communities. This provides us a set of testable hypotheses for drivers of microbial biodiversity. We then test these hypotheses by conducting a wide-variety of biotic and abiotic drivers in manipulative field experiments. By collaborating within global networks such as the Nutrient Network (NutNet) and Warming and Removal in Mountains (WaRM), as well as experiments established around Mobile, we can unravel the underlying factors driving microbial biodiversity.
Do fine-scale changes in plant microbiomes scale to influence community interactions
and ecosystem function across the landscape?
Changes in the composition of microbiome communities can alter plant host phenotype and performance, which can scale to shape plant community dynamics and ecosystem function. Using mesocosm approaches, our group explores how the diversity and composition of microbiome communities regulate host function. To conduct this work, our group is isolating and maintaining organisms from natural plant microbiomes and maintaining those microbial taxa within our lab. Then we are able to construct synthetic microbiome communities to understand how plant-microbiome and microbe-microbe interactions shape plant host function.
How will global change re-shape interactions among microbial communities, hosts, and
Global change alters plant productivity, carbon allocation to symbionts, and ecosystem inputs, which feedback to alter the structure and function of belowground symbiotic communities. To explore how global change is re-shaping the distribution of plant and soil communities and the subsequent feedback to community composition and ecosystem function, our group has established a wide variety of global change experiments in and around Mobile. We are interested in understanding how a wide variety of global change drivers, like eutrophication, habitat disturbance, drought, disease outbreaks, changes in herbivore density, and warming will shape the structure and function of ecosystems.
