Potential Stream Density in Mid-Atlantic US Watersheds (Page 1)

Potential Stream Density in Mid-Atlantic US Watersheds

Elmore AJ, Julian JP, Guinn SM, and Fitzpatrick MC ·
2013

Stream network density exerts a strong influence on ecohydrologic processes in watersheds, yet existing stream maps fail to capture most headwater streams and therefore underestimate stream density. Furthermore, discrepancies between mapped and actual stream length vary between watersheds, confounding efforts to understand the impacts of land use on stream ecosystems.

Reduction of the temperature sensitivity of soil organic matter decomposition with sustained temperature increase

Craine JM, Fierer N, McLauchlan KK, and Elmore AJ ·
2013

The degree to which microbial communities adjust their decomposition of soil carbon over time in response to long-term increases in temperature is one of the key uncertainties in our modeling of the responses of terrestrial ecosystems to warming. To better understand changes in temperature sensitivity of soil microbial communities to long-term increases in soil temperature, we incubated 27 soils for one year with both short-term and long-term manipulations of temperature.

Restoration of overwash processes creates piping plover (Charadrius melodus) habitat on a barrier island (Assateague Island, Maryland)

Schupp CA, Winn NT, Pearl TL, Kumer JP, Carruthers TJB, and Zimmerman CS ·
2013

On Assateague Island, an undeveloped barrier island along Maryland and Virginia, a foredune was constructed to protect the island from the erosion and breaching threat caused by permanent jetties built to maintain Ocean City Inlet. Scientists and engineers integrated expertise in vegetation, wildlife, geomorphology, and coastal engineering in order to design a habitat restoration project that would be evaluated in terms of coastal processes rather than static features.

Studying Nature In Situ: Immersive Education for Better Integrated Water Management (Page 1)

Studying Nature In Situ: Immersive Education for Better Integrated Water Management

Dennison WC, Oliver P ·
2013

The term immersive education is currently used in two educational areas – language education, which involves students being totally immersed in a language and its culture; and virtual education, where teachers use computers and simulation games to immerse learners in a virtual, computer-generated environment that mimics a real-world environment and allows learners to interact with it.

A Habitat-Based Framework for Communicating Natural Resource Condition (Page 1)

A Habitat-Based Framework for Communicating Natural Resource Condition

Carruthers TJB, Carter SL, Lookingbill TR, Florkowski LN, Hawkey JM, and Dennison WC ·
2012

Progress in achieving desired environmental outcomes needs to be rigorously measured and reported for effective environmental management. Two major challenges in achieving this are, firstly, how to synthesize monitoring data in a meaningful way at appropriate temporal and spatial scales and, secondly, how to present results in a framework that allows for effective communication to resource managers and scientists as well as a broader general audience.

Channel head locations in forested watersheds across the mid-Atlantic United States: A physiographic analysis

Julian JP, Elmore AJ, and Guinn SM ·
2012

Channel heads are the beginning of river networks and thus knowing their location is important in assessing water resources and health threats to fluvial ecosystems. Despite their importance, most channel heads are unmapped. Remote sensing technologies have not yet proven effective under forested canopies, suggesting that predictive models of channel head locations are the best solution to the impracticality of field-mapping the millions of these features that exist in the U.S. alone.

Impacts of Hypoxia on Zooplankton Spatial Distributions in the Northern Gulf of Mexico (Page 1)

Impacts of Hypoxia on Zooplankton Spatial Distributions in the Northern Gulf of Mexico

Roman MR, Pierson JJ, Kimmel DG, Boicourt WC, and Zhang X ·
2012

The northern Gulf of Mexico (NGOMEX) was surveyed to examine the broad-scale spatial patterns and inter-relationships between hypoxia (< 2 mg L-1 dissolved oxygen) and zooplankton biovolume. We used an undulating towed body equipped with sensors for conductivity, temperature, depth, oxygen, fluorescence, and an optical plankton counter to sample water column structure, oxygen, and zooplankton at high spatial resolution (1 m-vertical; 0.25-1 km-horizontal).

Landscape controls on the timing of spring, autumn, and growing season length in mid-Atlantic forests

Elmore AJ, Guinn SM, Minsley BJ, and Richardson AD ·
2012

The timing of spring leaf development, trajectories of summer leaf area, and the timing of autumn senescence have profound impacts to the water, carbon, and energy balance of ecosystems, and are likely influenced by global climate change. Limited field-based and remote-sensing observations have suggested complex spatial patterns related to geographic features that influence climate.

Megacities in the coastal zone: Using a driver-pressure-state-impact-response framework to address complex environmental problems (Page 1)

Megacities in the coastal zone: Using a driver-pressure-state-impact-response framework to address complex environmental problems

Sekovski I, Newton A, and Dennison WC ·
2012

The purpose of this study was to elaborate on the role of coastal megacities in environmental degradation and their contribution to global climate change. Although only less than 4 percent of the total world's population resides in coastal megacities, their impact on environment is significant due to their rapid development, high population densities and high consumption rate of their residents.
