Subject: PLSC399 Special Problems in Plant Science Description: Research Question: Effects of climate change, such as sea level rise and shifts in weather patterns, can cause saltwater intrusion. In rural coastal areas, the effects of saltwater intrusion may alter ecosystem functioning. Forests and crops can die off due to the slow creep of saltwater inland as well as from large pulses of salt water from estuaries or oceans during extreme storm events. When saltwater intrusion occurs along tidal areas near the boundaries of farmland and forests, aerobic soils transition to anaerobic tidal marsh soils. Agricultural soils that are shifting from an aerobic to an anaerobic state can undergo a series of chemical exchanges that can free phosphorus and nitrogen stored in the soils from decades of farming. This has major implications for water quality and nutrient management in coastal agricultural areas. The goal of this research is to explore trends in nutrient release due to saltwater intrusion in ecotones where farmland and forests are transitioning to tidal wetlands. Course Expectations: The student will assist with water and soil sample collection and analysis. This may require two to three trips to Maryland’s lower eastern shore. With guidance from Dr. Tully and Dani, the student will develop a portion of the study as his/her own project, which will involve the processing of a subset of samples, exploratory data analysis, and an end-of-semester report detailing the work completed. Requirements: No previous laboratory experience is necessary, as the student will be trained on all required skills during the semester. The goal of this internship is to provide the student with an introduction to soils and ecology research. To that effect, the student must have an interest in ecology and conservation, and like getting dirty!
