The $213,511 award will fund research to enhance the understanding of how flexible and rigid plant structures in river environments affect water flow and drag forces. The project involves a combination of experiments and numerical simulations to investigate these complex plant-water interactions, with the...
- This $307,496 project grant from the National Science Foundation's Division of Environmental Biology, under the Biological Sciences federal grant program (CFDA 47.074), will fund research at the Smithsonian Institution from January 2023 through December 2025. The research aims to better understand the role of trees in the global water and methane cycles. It will examine how water and environmental factors influence methane emissions from forest soils and trees, using radon as a novel tracer....
- This $396,079 Project Grant awarded by the National Science Foundation (NSF) Geosciences program (CFDA 47.050) aims to investigate how bacteria and biofilm growth in river sediments regulate the formation of low-oxygen microzones that produce the potent greenhouse gas nitrous oxide. The University of California, Davis (UC Davis) will perform sediment column experiments, microfluidic studies, and numerical simulations to characterize the spatio-temporal dynamics of these anoxic microzones and...
- This National Science Foundation Division of Environmental Biology Project Grant award to Indiana State University will fund a collaborative research project to quantify the response of biodiverse freshwater ecosystems to abrupt and progressive environmental changes, such as marine water inundation due to sea-level rise. The $338,197 project, running from January 1, 2024 to December 31, 2028, will use the Izabal/Golfete system in eastern Guatemala as a natural laboratory to investigate how...
- This $281,419 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research to generalize drag estimation for rigid and flexible vegetation canopies and quantify their interactions with water flow. The University of Illinois, the primary awardee, will conduct experiments and numerical simulations to investigate how different types of aquatic plant canopies affect water flow and drag forces. The research aims to enhance the ability to...
- This $372,598 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) will support research to incorporate stream biogeochemistry into carbon assessment models for enhanced rock weathering, a carbon dioxide removal approach. The project aims to add biological processes like photosynthesis and respiration into a dynamic river network model to better quantify the fate of bicarbonate generated through enhanced rock weathering. This will help identify river...
- The National Science Foundation awarded a $432,778 Project Grant to the University of Connecticut under the Geosciences program (CFDA 47.050) for research titled "Collaborative Research: The Effects of Terrestrial Organic Matter Inputs on Coastal Mercury Cycling, Methylmercury Production and Bioaccumulation." The three-year award beginning June 1, 2022 will support research examining how increased terrestrial organic matter delivery to coastal waters from climate change influences...
RAPID: INVASIVE HYDRILLA AND CARBON CYCLING: LEVERAGING AN ECOSYSTEM-SCALE HERBICIDE APPLICATION TO INVESTIGATE FEEDBACKS BETWEEN INVASIVE PLANTS AND GREENHOUSE GAS EMISSIONS -HYDRILLA VERTICILLATA IS AN INVASIVE AQUATIC PLANT THAT IS RAPIDLY SPREADING IN FRESHWATERS ACROSS THE EASTERN UNITED STATES, INCLUDING THE LOWER CONNECTICUT RIVER. WITH LARGE ENVIRONMENTAL AND ECONOMIC IMPACTS, HYDRILLA IS ONE OF THE MOST PROBLEMATIC INVASIVE AQUATIC PLANTS IN THE UNITED STATES. HYDRILLA FORMS DENSE SUBMERGED MATS OR CANOPIES, WHICH IMPACT NATIVE HABITATS, HYDROLOGY, CARBON CYCLING, AND RECREATION. TO CONTROL THE SPREAD OF HYDRILLA, EXPERIMENTAL HERBICIDES WILL BE APPLIED TO AFFECTED AREAS IN THE LOWER CONNECTICUT RIVER IN SUMMER 2024. THIS RAPID PROJECT WILL LEVERAGE THESE HERBICIDE APPLICATIONS AS A UNIQUE PLANT-REMOVAL EXPERIMENT TO BETTER UNDERSTAND THE EFFECTS OF HYDRILLA ON FRESHWATER ECOSYSTEMS. THE OVERARCHING GOAL OF THE PROJECT IS TO UNDERSTAND HOW THIS INVASIVE AQUATIC PLANT CAN ALTER CARBON CYCLING AND GREENHOUSE GAS EMISSION IN INLAND WATERS. THIS RESEARCH IS IMPORTANT FOR UNDERSTANDING THE FULL IMPACTS OF INVASIVE AQUATIC PLANTS ON ECOSYSTEM FUNCTION AND POTENTIAL LINKAGES BETWEEN CLIMATE CHANGE AND INVASIVE AQUATIC PLANTS VIA GREENHOUSE GASES. FINDINGS WILL INFORM AQUATIC PLANT MANAGEMENT. THIS RESEARCH WILL EXPLORE HOW CARBON CONCENTRATING MECHANISMS THAT HELP INVASIVES LIKE HYDRILLA OUTCOMPETE NATIVE SPECIES CAN SHIFT ECOSYSTEM-SCALE PRIMARY PRODUCTIVITY FROM USING ONLY CARBON DIOXIDE TO ALSO USING BICARBONATE, A NON-GASEOUS FORM OF INORGANIC CARBON. BICARBONATE UPTAKE BY HYDRILLA HAS THE POTENTIAL TO TRANSFER CARBON FROM THE SLOW-CYCLING GEOLOGIC POOL (BICARBONATE HAS GEOLOGIC SOURCES) TO THE FASTER-CYCLING BIOLOGIC POOL (CARBON DIOXIDE IN INLAND WATERS LARGELY COMES FROM RESPIRATION). THIS STUDY WILL USE OXYGEN AND CARBON DIOXIDE SENSORS AND GRAB SAMPLES TO COMPARE ECOSYSTEM METABOLISM AND CARBON CYCLING IN TREATED AND UNTREATED EMBAYMENTS. WEEKLY SAMPLES WILL BE USED TO ASSESS GREENHOUSE GAS EMISSIONS. ANALYSES WILL DETERMINE THE EXTENT OF BICARBONATE UPTAKE BY HYDRILLA AND THE CASCADING IMPACTS ON CARBON CYCLING PROCESSES. THIS AWARD REFLECTS NSF'S STATUTORY MISSION AND HAS BEEN DEEMED WORTHY OF SUPPORT THROUGH EVALUATION USING THE FOUNDATION'S INTELLECTUAL MERIT AND BROADER IMPACTS REVIEW CRITERIA.- SUBAWARDS ARE PLANNED FOR THIS AWARD.
