13C isotopic signature and C concentration of soil density fractions illustrate reduced C allocation to subalpine grassland soil under high atmospheric N deposition (JOURNAL)
We followed soil C fluxes in a subalpine grassland system exposed to experimentally increased atmospheric N deposition for 7 years. Earlier we found that, different from the plant productivity response, the bulk soil C stock increase was highest at the medium, not the high N inpu...
2012 Annual Report to Characterize the Ottawa River Using Physical, Biological, and Chemical Lines of Evidence (PUBLISHED REPORT)
International concern about contaminated sediments is increasing as sustainable practices are needed to maintain water resources and waterways as important economic, commercial, recreational, and community resources. Sediments often serve as long-term sinks for legacy pollutants,...
A 72-HOUR STUDY WITH GRAPHENE OXIDE NANOPARTICLES AND EASTERN OYSTERS (PRESENTATION)
Graphene family nanomaterials (GFNs) are widely used in the field of electronics and biomedicine. Gaps in our knowledge about fate and toxicity of GFNs, such as graphene oxide (GO), raise concerns regarding their environmental impacts. Filter feeding bivalves, such as Crassostrea...
A Maieutic Exploration of Nudging Strategies for Regional Climate Applications Using the WRF Model (JOURNAL)
The use of nudging in the Weather Research and Forecasting (WRF) Model to constrain regional climate downscaling simulations is gaining in popularity because it can reduce error and improve consistency with the driving data. While some attention has been paid to whether nudging i...
A National Approach to Assess Terrestrial Vertebrate Biodiversity within an Ecosystem Services Framework: An Example using the Reptiles and Amphibians of the Mojave Ecoregion (PRESENTATION)
Biodiversity is crucial for the functioning of ecosystems and the products and services from which we transform natural assets of the Earth for human survival, security, and well-being. The ability to assess, report, map, and forecast the life support functions of ecosystems is a...
A Science-Governance Partnership for Integrating Ecosystem Services into Puget Sound Restoration Planning (PRESENTATION)
Numerous studies have established that impacts from mounting population and climatic pressures are decreasing the capacity of coastal watersheds and estuaries to provide services essential to human health and well-being – clean drinking water, flood protection, habitat for ...
A linked land-sea modeling framework to inform ridge-to-reef management in high oceanic islands (JOURNAL)
Declining natural resources have led to a cultural renaissance across the Pacific that seeks to revive customary ridge-to-reef management approaches to protect freshwater and restore abundant coral reef fisheries. Effective ridge-to-reef management requires improved understanding...
A simplified method for extracting microplastics in laboratory-cultured coral and water samples (PRESENTATION)
The deleterious effects of microplastic ingestion by marine organisms and the impacts across trophic levels are widely unknown. Due to the extensive ecological and socioeconomic benefits provided by coral reefs, investigating the impacts of microplastics on reef ecosystems is of ...
AOP-informed assessment of endocrine disruption in freshwater crustaceans (PRESENTATION)
To date, most research focused on developing more efficient and cost effective methods to predict toxicity have focused on human biology. However, there is also a need for effective high throughput tools to predict toxicity to other species that perform critical ecosystem functio...
Achieving SDGs [Sustainable Development Goals] and Engaging Higher Education Using EPA Tools (PRESENTATION)
The U.S. Environmental Protection Agency (EPA) provides a suite of freely available, web-based tools that assist diverse audiences, including higher education institutions, in tackling local and regional environmental problems, building capacity, and meeting their sustainability ...

This fact sheet provides information about EPA's Ada, OK facility, Robert S. Kerr Environmental Research Center, and will be available to the public.
An evaluation of factors controlling the abundance of epiphytes on Zostera marina along an estuarine gradient in Yaquina Bay, Oregon, USA. (JOURNAL)
Epiphytes on seagrass (Zostera marina) growing in the lower intertidal were examined along an estuarine gradient within Yaquina Bay, Oregon over a period of 4 years. The Yaquina Estuary receives high levels of nutrients from the watershed during the wet season and from the ocean...
Application of Decision Support Tools for Integrated Water Resources Management (PRESENTATION)
Integrated Water Resources Management (IWRM) involves “a process which promotes the coordinated development and management of water, land, and related resources in order to maximize the resultant economic and social welfare in an equitable manner without compromising the su...
Application of a density dependent logistic matrix model to investigate the effects of chemical stress and resource limitation on fish populations (PRESENTATION)
Matrix population models are useful tools for ecological risk assessment because they integrate effects across the life cycle, link endpoints observed in the individual and ecological risk to the population, and project outcomes for many generations in the future. The Atlantic ki...
