51在线Biology Professors Receive $1 Million National Science Foundation Grant for Wetlands Research

Langley Chapman Wetlands

VILLANOVA, Pa.鈥51在线鈥檚 Samantha Chapman, PhD, and Adam Langley, PhD, professors in the Department of Biology and two of the founding faculty of the Center of Biodiversity and Ecosystem Stewardship in the College of Liberal Arts and Sciences, are principal investigators on a $1 million grant from the National Science Foundation (NSF) to support their project, 鈥淭he Interplay of Nitrogen Loading and Ecosystem Sustainability in Threatened Wetlands.鈥

鈥淒rs. Chapman and Langley鈥檚 research is critical to our understanding of climate change, and this grant is a testament to the value of their work to the scientific community and the public, says Adele Lindenmeyr, PhD, William and Julia Moulden Dean. 鈥淲e are also grateful for the opportunities this NSF grant allows for our students, as Drs. Chapman and Langley will be able to involve more undergraduate and graduate researchers in their important work.鈥

Nitrogen pollution from fertilizer, septic tanks, and cities often courses over wetlands, which help extract this pollutant from surrounding waters. A healthy wetland can remove large amounts of nitrogen from the environment, but some evidence suggests too much nitrogen can overwhelm a wetland and cause it to collapse.

The grant will fund experiments in marshes and mangrove swamps around St. Augustine, Florida. Florida produces high levels of nutrient pollution, resulting in fish and manatee die-offs, among many other negative effects. The project aims to learn more about the effect nutrient pollution has on coastal wetlands and how ecosystems can help remove nutrients.

鈥淭his research has very tangible and pressing implications for the ecosystems that protect our coastline and the people that rely on them,鈥 Langley said. 鈥淲e are posing challenging questions that we hope can be answered with experimentation in complex and dynamic ecosystems. Without substantial support from agencies like NSF, we couldn鈥檛 establish experiments on this scale in these harsh environments and run them for long enough to see the results unfold.鈥

The grant also secures funding for two 51在线graduate students and several undergraduate students to assist in conducting the research. 51在线will collaborate with the University of Central Florida and The Guana Tolomato Matanzas National Estuarine Research Reserve.
