NLOAD : an interactive, web-based modeling tool for nitrogen management in estuaries
(Ecological Society of America, 2007-07)
Eutrophication of estuaries is an increasing global concern that requires development of new tools to identify causes, quantify conditions, and propose management options that address this environmental problem. Since ...
Net exchanges of CO2, CH4, and N2O between China's terrestrial ecosystems and the atmosphere and their contributions to global climate warming
(American Geophysical Union, 2011-05-13)
China's terrestrial ecosystems have been recognized as an atmospheric CO2 sink; however, it is uncertain whether this sink can alleviate global warming given the fluxes of CH4 and N2O. In this study, we used a process-based ...
Forecasting effects of sea-level rise and windstorms on coastal and inland ecosystems
(Ecological Society of America, 2008-06)
We identify a continental-scale network of sites to evaluate how two aspects of climate change – sea-level rise and intensification of windstorms – will influence the structure, function, and capacity of coastal and inland ...
Testing isosource : stable isotope analysis of a tropical fishery with diverse organic matter sources
(Ecological Society of America, 2006-02)
We sampled consumers and organic matter sources (mangrove litter, freshwater swamp-forest litter, seagrasses, seagrass epiphytes, and marine particulate organic matter [MPOM]) from four estuaries on Kosrae, Federated States ...
Thinking outside the channel : modeling nitrogen cycling in networked river ecosystems
(Ecological Society of America, 2010-09-08)
Agricultural and urban development alters nitrogen and other biogeochemical cycles in rivers worldwide. Because such biogeochemical processes cannot be measured empirically across whole river networks, simulation models ...
Biomass and toxicity responses of poison ivy (Toxicodendron radicans) to elevated atmospheric CO2 : reply
(Ecological Society of America, 2008-02)
Aggregate measures of ecosystem services : can we take the pulse of nature?
(Ecological Society of America, 2005-02)
National scale aggregate indicators of ecosystem services are useful for stimulating and supporting a broad public discussion about trends in the provision of these services. There are important considerations involved in ...
The application of δ18O and δD for understanding water pools and fluxes in a Typha Marsh
The δ18O and δD composition of water pools (leaf, root, standing water, and soil water) and fluxes (transpiration, evaporation) were used to understand ecohydrological processes in a managed Typha latifolia L. freshwater ...
Susceptibility of salt marshes to nutrient enrichment and predator removal
The sustainability of coastal ecosystems in the face of widespread environmental change is an issue of pressing concern throughout the world (Emeis et al. 2001). Coastal ecosystems form a dynamic interface between terrestrial ...
Separation of river network–scale nitrogen removal among the main channel and two transient storage compartments
(American Geophysical Union, 2011-08-30)
Transient storage (TS) zones are important areas of dissolved inorganic nitrogen (DIN) processing in rivers. We assessed sensitivities regarding the relative impact that the main channel (MC), surface TS (STS), and hyporheic ...
