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 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...
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...
Applying fingerprint Fourier transformed infrared spectroscopy and chemometrics to assess soil ecosystem disturbance and recovery (JOURNAL)
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...
Aquatic Sentinels Forecasting Human Exposure To Emerging Contaminants (PRESENTATION)
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...
Assessing Multi-scale Reptile and Amphibian Biodiversity: Mojave Ecoregion Case Study (PRESENTATION)
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...
Assessing threats of non-native species to native freshwater biodiversity: Conservation priorities for the United States (JOURNAL)
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...
Can we adequately represent the spatial interplay between humans and nature? (PRESENTATION)
One of the challenges remaining before ecosystem services assessments can become part of mainstream decision making is how to spatially represent the interplay of nature as a whole and humans. Nature’s ecosystems act as natural capital by producing things (i.e. stocks and ...
Carbon Stable Isotope Values in Plankton and Mussels Reflect Changes in Carbonate Chemistry Associated with Nutrient Enhanced Net Production (JOURNAL)
Coastal ecosystems are inherently complex and potentially adaptive as they respond to changes in nutrient loads and climate. We documented the role that carbon stable isotope (δ13C) measurements could play in understanding that adaptation with a series of three Ecostat (i.e...
Comparing Pixel- and Object-Based Approaches in Effectively Classifying Wetland-Dominated Landscapes (JOURNAL)
Wetland ecosystems straddle both terrestrial and aquatic habitats, performing many ecological functions directly and indirectly benefitting humans. However, global wetland losses are substantial. Satellite remote sensing and classification informs wise wetland management and moni...
Comprehensive Status and Trends of Nitrogen Loads to Estuaries in the Conterminous United States: Pacific Coast Results (PRESENTATION)
We applied regional SPARROW (SPAtially Referenced Regressions On Watershed attributes) models to estimate status and trends of potential nitrogen loads to estuaries of the conterminous United States. The original Regional SPARROW models predict average detrended loads by source ...
Connectivity of streams and wetlands to downstream waters: an integrated systems framework (JOURNAL)
