Metatranscriptomic Analyses of Plankton Communities Inhabiting Surface and Subpycnocline Waters of the Chesapeake Bay during Oxic-Anoxic-Oxic Transitions

Creator:: Hewson, Ian, Eggleston, Erin M., Doherty, Mary, Lee, Dong Yoon, Owens, Michael, Shapleigh, James P., Cornwell, Jeffrey C., and Crump, Byron C.
Abstract:: We used metatranscriptomics to study the gene transcription patterns of microbial plankton (0.2 to 64 μm) at a mesohaline station in the Chesapeake Bay under transitions from oxic to anoxic waters in spring and from anoxic to oxic waters in autumn. Samples were collected from surface (i.e., above pycnocline) waters...

Stable Isotope Constraints on Carbon Dioxide and Nitrous Oxide Variations at the Onset of the Last Glacial Period: New Ice Cores from Taylor Glacier, Antarctica

Creator:: Menking, James A.
Abstract:: New ice cores retrieved from the Taylor Glacier (Antarctica) blue ice area contain ice and air spanning the Marine Isotope Stage (MIS) 5/4 transition, a period of global cooling and ice sheet expansion. Chronologies were determined for the ice and air bubbles in the new ice cores by visually matching...

Persistence of Populations in Environments with an Interface

Creator:: Rekow, James A.
Abstract:: We model a fish population in a spatial region comprising a marine protected area and a fishing ground separated by an interface. The model assumes conservation of biomass density and takes the form of a reaction diffusion equation with a logistic reaction term. At the interface, in addition to continuity...

The influence of participating in a mandatory mixed-format student success seminar on persistence in an urban community college

Creator:: Mendoza, James A.
Abstract:: Over the past twenty years, the national three-year graduation rate for community college students has ranged from 44% to roughly 31% in 2013 (NCES, 2013). As a way to address such low graduation rates, colleges have implemented a myriad of services and programs (i.e., tutoring, mentoring, etc.). Another intervention is...

The effects of alternative future development scenarios on ecological processes and social-ecological resilience in Central Oregon

Creator:: Duncan, James A.
Abstract:: This research sought to explore the implications of different tenure regimes for both landscape-level ecological processes and the overall resilience of a social-ecological system in Central Oregon. The purchase by an investor of former industrial timberlands known as the Bull Springs tract raised the specter of dispersed residential development on...

Knowledge is Power? Redrawing the Asymmetries of Data Deficiencies in Global Value Chains Linking Bangladesh, Thailand and Europe

Creator:: Kelling, Ingrid and Young, James A.
Abstract:: The generation of market information is critical in the dynamic and highly differentiated global seafood market. Information has strategic value and market information is therefore vital in creating and delivering value. However, the context of long, globalised supply chains and highly differentiated seafood markets results in value chain members having...

Knowledge is Power? The role of market information in value creation by developing country aquaculture producers

Creator:: Kelling, Ingrid and Young, James A.
Abstract:: International seafood trade takes place through value chains that link production in developing countries to developed country markets. As a result of the emergence of the global value chain analytical framework from the political economy of development (and underdevelopment) approach, value chain analysis has traditionally maintained a production orientation to...

Planning Best Management Practices to Reduce Sediment Delivery from Forest Roads Using WEPP:Road Erosion Modeling and Simulated Annealing Optimization

Creator:: Efta, James A. and Chung, Woodam
Abstract:: Planning and implementation of road BMPs on a watershed scale can be a difficult task because of the need to prioritize locations while accounting for multiple constraints, such as the available budget, continuous maintenance, and equipment scheduling. Using simulated annealing (SA) as its heuristic optimizer, BMP-SA accounts for sediment being...

Market Dynamics and Governance in Global Aquaculture Value Chains: Chaining Producers?

Creator:: Kelling, Ingrid and Young, James A.
Abstract:: The expansion of the aquaculture sector over the last two decades has coincided with the growth in importance of supermarkets in fish retailing in the EU. This paper presents a Value Chain analysis of selected species from their point of production in Bangladesh to the major consumer markets in Europe,...
