Federal Project Grant Award Summary

The University of Connecticut received a $146,417 Project Grant from the National Science Foundation (NSF) Division of Environmental Biology under the Biological Sciences program (CFDA 47.074), effective September 1, 2026 through August 31, 2029. This collaborative research initiative investigates belowground resource partitioning mechanisms that enhance forest productivity and ecosystem function in mixed-species forests compared to monocultures. The project employs three complementary methodological approaches: state-of-the-art belowground imaging tools such as ground-penetrating radar to map root distributions, isotopic tracers to quantify differential water and nitrogen uptake, and detailed root morphological trait measurements coupled with genetic identification of mycorrhizal fungi. Research findings will leverage North America's longest-running large-scale forest biodiversity experiment to directly measure resource partitioning rather than inferring it, thereby advancing understanding of the relationship between tree species richness and forest ecosystem function.

The project delivers significant workforce development and public engagement products alongside research outputs. Deliverables include training opportunities for undergraduate interns, graduate students, and a postdoctoral researcher; public engagement through interpretive exhibits; K-12 curriculum development in partnership with the Smithsonian Learning Lab; and a workshop for forest restoration practitioners. These outputs collectively address critical needs for predicting future forest productivity and designing effective reforestation strategies while advancing the Nation's scientific workforce in biological sciences.
