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...

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,...

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...

From the earliest days of public health, environmental protection has been fundamental to preventing disease and ensuring a healthy population. From John Snow and the Broad Street Pump to chlorinated drinking water in Jersey City, NJ, protecting the environment has been a core pu...

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...

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...

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 ...

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...

The distribution of pattern across scales has predictive power in the analysis of complex systems. Discontinuity approaches remain a fruitful avenue of research in the quest for quantitative measures of resilience because discontinuity analysis provides an objective means of iden...

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 ...

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...

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.

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...

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...

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...

The ability to assess, report, map, and forecast the life support functions of ecosystems is absolutely critical to our capacity to make informed decisions that help maintain the sustainable nature of our environment now and into the future. Because of the variability among livin...

The assessment and monitoring of soil disturbance and its effect on soil quality (i.e., ability to support a range of ecosystem services) has been hindered due to the shortcomings of many traditional analytical techniques, including high cost, long-term time investment and diffic...

Carbon and nutrient dynamics in aquatic systems often emerge as the result of hydrological, biogeochemical, and ecological interactions. Due to the multi‐scale and multi‐disciplinary nature of these process interactions, research into aquatic carbon and nutrient dynam...

Most of us have heard the axiom, “canary in the coal mine”. These melodious exposure indicators - a necessity in U.K. mines well into the 20th century - were especially sensitive to methane and carbon monoxide gases, and would cease singing (and oftentimes die) at le...

The ability to assess, report, map, and forecast the life support functions of ecosystems is absolutely critical to our capacity to make informed decisions to maintain the sustainable nature of our environment now and into the future. Because of the variability among living orga...

Cell-based metabolomics was used in a proof-of-concept fashion to investigate the biological effects of contaminants as they traveled from a wastewater treatment plant (WWTP) discharge to a drinking water treatment plant (DWTP) intake in a surface water usage cycle. Zebrafish liv...

Non-native species pose one of the greatest threats to native biodiversity, and can have severe negative impacts in freshwater ecosystems. Identifying regions of spatial overlap between high freshwater biodiversity and high invasion pressure may thus better inform the prioritizat...

Uncertainty in measurements of atmospheric deposition results from analytical uncertainty in the measurements themselves, from the completeness of the suite of species analyzed with respect to the significant forms of nitrogen that impact the deposition budget, and from ‘sc...

Cities and urban agglomerations are undeniably becoming humanity’s habitat as they embody the centers of economic, educational, and social activities; in fact, about 70% of the world’s population is expected to live in urban areas by 2050. These urban areas significan...
