The National Science Foundation (NSF) Division of Environmental Biology awarded a $211,758 Project Grant to The Administrators Of The Tulane Educational Fund, doing business as Tulane University, under the Biological Sciences (CFDA 47.074) program. The grant supports a 3-year research project to explore the interplay between plant-pathogen interactions and environmental stressors, such as increased salinity, affecting freshwater swamp trees along the Gulf of Mexico and Atlantic coasts. The project will test hypotheses about how negative feedback from plant-microbial symbioses is influenced by salinity gradients, as well as evaluate the potential for using recycled crushed glass as an alternative growth substrate for coastal restoration. Broader impacts include engaging community organizations and providing data to support a local glass recycling startup. This research aims to address a knowledge gap regarding the relationship between negative feedback and environmental stress, which has implications for understanding ecological processes as climate-related stressors increase.
