Hello Everyone,
Please join us on Thursday Feb. 28 for this week's Enviro-Lunch talk by Yang Yang from Southern Nevada Research Institute, at 12-1pm in room SE2-302.

Understanding the pathway and accumulation of carbon, nutrient, mercury in forest ecosystems: case studies of uncertainty analysis and climate impacts in New England
 [cid:ad22f6b4-20b9-4e65-a3f3-a3bbc3371167]
Abstract:Theme I- Understanding carbon and nutrient fluxes and pools in forested ecosystems requires monitoring work in both space and time. Some uncertainty in flux or pool estimate is due to imperfect measurement, such as errors in collection, sample processing, and analytical analysis. Unlike measurement errors, natural variation cannot be reduced but can be better characterized by improved sampling schemes. I will present my past work using uncertainty analysis to optimize sampling schemes in monitoring leaf litterfall biomass and nutrients, root biomass, and soil carbon and nutrients.
Theme II- Mercury (Hg) is a neurotoxic pollutant emitted to the atmosphere by anthropogenic activities and natural processes that can be transported long distances and deposited to remote forested areas. Soils are the largest pool of Hg on land. Pathways of Hg accumulation and loss in forest soils include throughfall, litterfall, soil gas fluxes, and leaching in soil solutions, all of which will likely be altered under changing climate. I will present my past work comparing Hg inputs in throughfall and leaf litterfall and Hg outputs in soil gas fluxes and soil solution at three ongoing climate-change manipulation experiments at the Hubbard Brook Experimental Forest, New Hampshire, USA.

Bio:I am a postdoc working at the Southern Nevada Research Institute. I am interested in biogeochemical cycle (e.g. carbon, nitrogen, mercury) in forest and freshwater ecosystems. I was involved in projects using uncertainty analysis to optimize sampling intensity in ecosystem monitoring, as part of the QUEST<https://www.esf.edu/quest/>network. I earned a M.S. in forest ecology and management in 2015 and a PhD in Environmental Science in 2018, both at State University of New York College of Environmental Science and Forestry (SUNY-ESF).

When: Thursday 2/28, 12pm – 1pm

Where: SE2-302

Coffee will be provided, please bring your own mugs.

We look forward to seeing you,

Jing & Jennifer
