Riparian Nitrogen Dynamics in Tropical Forest Groundwaters: A Challenge to Our Understanding of Near-Stream Ecosystem Function
Poster Number: 402 Presenter/Primary Author: Richard Brereton Riparian zones are widely understood to control the flux of water, nutrients, and carbon from terrestrial to aquatic ecosystems.
Examining the mechanistic basis of summer nitrate peaks: a coupled biogeochemical and hydrological approach
Poster Number: 389 Presenter/Primary Author: Jonathan Duncan Contrary to behavior predicted by the nitrogen saturation hypothesis, Pond Branch (the Baltimore Ecosystem Study forested reference watershed) exhibits peak nitrogen export during the growing seaso
Nitrous Oxide Fluxes As a Function of Diffusion and Profile Concentrations in the Upper Meter of an Agricultural Soil
Poster Number: 382 Presenter/Primary Author: Iurii Shcherbak Nitrous oxide (N2O) production in arable soils is a major part of agricultural GHG emissions but not much is known about subsurface sources of N2O.
Detecting the sensitivity of desert herbaceous plant responses to co-occurring atmospheric compounds
Poster Number: 379 Presenter/Primary Author: Elizabeth Cook Cities occupy a small land area globally, yet atmospheric compounds generated from human-dominated ecosystems have significant impacts on protected lands within and beyond urban boundaries. D
Greenhouse gas emissions from a constructed wetland system in Phoenix, AZ
Poster Number: 365 Presenter/Primary Author: Jorge Ramos Wetlands support ecological functions that result in valuable services to society, including the purification of water through processes such as denitrification, plant uptake, and soil retention.
