The Office of the Vice President for Research is pleased to host the next Water@Wayne seminar on Thursday, April 5, 2018 from 2:30 to 3:30 p.m. in the Bernath Auditorium located in the David Adamany Undergraduate Library. The seminar is free and open to the public; registration is requested.

The Water@Wayne Seminar Series presents, "Controls on Biogeochemical Cycling Of Nitrogen and Carbon In Urban Ecosystems," with Pamela Templer, Ph.D., Boston University. Dr. Templer is a professor of biology and director of the Ph.D. program in biogeoscience at Boston University. She is also associate chair of the Department of Biology and co-director of the Stable Isotope Laboratory at Boston University. Pamela is an ecosystem ecologist and biogeochemist who examines the influence that plant-microbial interactions have on nutrient cycling and carbon exchange in terrestrial ecosystems. She is particularly interested in the effects that human activities such as climate change, urbanization, and air pollution have on forest ecosystems. 

Abstract:

Rates of atmospheric nitrogen deposition are declining across much of the United States and Europe, yet they remain substantially elevated by almost an order of magnitude over pre-industrial levels and occur as hot spots in urban areas. Dr. Templer's team measured atmospheric inputs of inorganic and organic nitrogen in multiple urban sites around the Boston Metropolitan area, finding that urban rates are substantially elevated compared to nearby rural areas, and that the range of these atmospheric inputs are as large as observed urban to rural gradients. Their data shows that a major consequence of this network design is that hotspots of nitrogen deposition are likely underestimated to a significant degree. A more complete determination of atmospheric nitrogen deposition and its fate in urban ecosystems is critical for closing regional nitrogen budgets and for improving our understanding of biogeochemical nitrogen cycling across multiple spatial scales. They also found that growing season soil respiration is dramatically enhanced in urban areas and represents levels of carbon dioxide efflux to the atmosphere of up to 72% produced by fossil fuel combustion within greater Boston’s residential areas. As the scientific community moves rapidly towards monitoring, reporting, and verification of carbon dioxide emissions using ground based approaches and remotely-sensed observations to measure carbon dioxide concentrations, their results show that measurement and modeling of biogenic urban carbon dioxide fluxes will be a critical component for verification of urban climate action plans.

A short reception will immediately follow the seminar.
