Yahn-Jauh's research focuses on ecosystem ecology and biogeochemistry; especially the carbon budget and carbon dynamics of ecosystems and their regulators. He measures chamber-based soil respiration, photosynthetic rate, and leaf area index with climate factors in biofuel crops in southwest Michigan at the Kellogg Biological Station and explores crop-ecosystem carbon dynamics by combining eddy-covariance carbon flux data. His interests also include modeling the relationship of climate regimes, ecosystem carbon sequestration, and its components underneath different biofuel crops and land use histories.

Research

In this project, we use the eddy covariance (EC) method as our primary tool in making intensive, continuous measurements of net ecosystem production (NEP), water loss through evapotranspiration (ET), and energy balance at six "scale-up fields" jointly studied by Kellogg Biological Station and Great Lakes Bioenergy Research Center: switch grass, restored prairie and continuous corn fields (two replicates of each system).

We hypothesize that significant differences exist in ecosystem production, biophysical regulations and below-ground carbon allocation among the three biofuel production systems. These differences are clearly reflected at multiple temporal scales.
