This $503,649 Project Grant was awarded by the National Science Foundation (NSF) under the Biological Sciences program (CFDA 47.074) to the Division of Agriculture of the University of Arkansas. The project aims to quantify how salinization, which can subsidize or stress organisms, alters carbon processing across terrestrial-aquatic boundaries. Key activities include:

  1. Measuring field relationships between terrestrial and stream ecosystems across a salinization gradient through a decomposition study.

  2. Experimentally determining in paired terrestrial-aquatic mesocosms how soil salinization impacts carbon exchange across a salinity gradient.

  3. Quantifying the relationship between the field and mesocosm measurements of decomposition rates across the salinity gradient.

The research will support three female principal investigators, mentorship of graduate and undergraduate students, and citizen science engagement. The 3-year project period runs from August 1, 2024 to July 31, 2027.
