个人简介

Dr. John Kominoski – Principal Investigator My research explores various scales of organic matter processing along gradients of environmental drivers within and among ecosystems. I am currently investigating how 1) seasonal variation in hydrology and organic matter dynamics influence whole aquatic ecosystem metabolism, 2) ecosystem process rates scale in river networks, 3) variation in dissolved nutrient concentrations (nitrogen, N; phosphorus, P) and N:P ratios influences microbial organic matter process rates and whole-stream ecosystem metabolism, and 4) how climate versus human water use variation influence freshwater flow regimes and biodiversity dynamics throughout the U.S. Sunbelt (Southeast vs Southwest U.S.). I am co-PI of the Florida Coastal Everglades Long Term Ecological Research Program for which I lead research projects investigating: 1) wet and dry season dynamics on aquatic ecosystem metabolism as driven by water column depth and flocculent organic matter, 2) subsidy-stress effects of saltwater intrusion on wetland soil ecosystems, and 3) long-term interactive effects of storm-induced phosphorus loading and drought on ecosystem productivity and nutrient dynamics spanning freshwater, brackish, and marine wetlands.

研究领域

My research group is broadly interested in exploring the functional implications of biodiversity loss and global environmental change in terrestrial and aquatic ecosystems. My research has focused on the indirect effects of elevated atmospheric CO2 and human land-use on aquatic ecosystems, as well as the importance of resource and consumer diversity in determining organic matter processing in terrestrial and aquatic ecosystems.
