The Virginia Coast Reserve (VCR) is an extremely dynamic, heterogeneous coastal barrier landscape comprising mainland watersheds, tidal marshes, lagoons, and barrier islands. Our goal for the VCR LTER program is to develop a predictive understanding of the response of coastal barrier systems to long-term environmental changes in climate, sea level and land use, and to relate these to the ecological services the coastal barrier systems provide.

A monthly and annual water budget has been created for the entire Shark River Slough (SRS) within the Everglades National Park (ENP) over 2002-2008. Inputs considered are surface water inflows (S12s and S333 canal structures) and rainfall, while outputs consist of discharge to the Gulf of Mexico (Lostman, Shark, Broad, Harney and North rivers) and evapotranspiration (ET).

An ongoing field experiment to test if zonation of tidal marsh vegetation is in synchrony with hydrologic conditions developed during rising sea level

A field experiment has been initiated in August 2008 to determine if the vegetation of a coastal marsh is in synchrony with hydrologic conditions that have developed with rising sea-level. The hypothesis being tested is that plant community structure will persist in existing zones of vegetation in the face of sea-level rise unless disturbance provides opportunities for species change under more frequent tidal inundation.

The KBS LTER site is in a diverse, rural-to-semirural landscape typical of the U.S. Great Lakes and upper Midwest regions. Research at KBS asks how diverse plants, animals, and microbes in agricultural landscapes can contribute to farm productivity, environmental performance, and profitability. We study annual and perennial crops including corn, soybean, and wheat rotations, forage crops such as alfalfa, and biofuel crops such as poplars, switchgrass, and native successional communities.

Factors mediating the distribution of Suaeda linearis in Georgia coastal marshes

In Georgia coastal marshes, the annual marsh plant Suaeda linearis is usually found in association with oyster shell deposits. Dense piles of oyster shells in the marsh support low densities of dominant salt marsh plants but are the primary locations where we find S. linearis. We hypothesized that in oyster shell deposits, abiotic stresses (e.g. lower soil water content due to faster drainage) would decrease densities of marsh plants, therefore, lowering competition and enabling the relatively drought-resistant S. linearis to survive.

Cross-Site Working Group on Coupled Human-Natural Systems

Cross-Site Working Group on Coupled Human-Natural Systems Final Report

Organizer:

William Freudenburg

Co-organizer(s):

Craig Harris

This session is intended both for social and biophysical scientists who want to help develop a proposal for the kind of “multi-site, highly collaborative and integrated research initiative” envisioned by the LTER planning group. The focus will be on what the LTER planning process calls the “centerpiece” of the group's conceptual framework, as well as one of “Grand Challenges” to be addressed at the network level – “the dynamics of coupled human-natural ecosystems.”

Land uses and management practices in residential parcels (e.g., aesthetic/recreational/economic uses, land-cover choices, irrigation and chemical applications) impact and are impacted by social (e.g., stratification and status, environmental perceptions, zoning) and ecological (e.g., carbon sequestration, nutrient cycling, water demand and quality) processes.

Influence of Sea Level Rise on Coastal Wetland Ecosystems

The purpose of this workshop is to exchange information about ongoing LTER research projects about the effects of sea level rise on coastal wetlands. The intent is to identify common observational and experimental datasets at coastal wetland LTER sites that can be used to generate cross-site comparative analyses of how coastal wetlands respond to sea level rise. Examples of common approaches to measuring long-term change in coastal wetlands might include eddy covariance towers, sediment elevation tables, organic matter flux and metabolism measurements and marsh organ experiments.

Sediment Total Phosphorus Concentrations in Shallow Freshwater Ecosystems in an Agricultural Landscape

Phosphorus (P) is often limiting in aquatic ecosystems. The quantity of available P is often determined by sediment binding and release processes. We obtained 32 sediment samples from shallow freshwater ecosystems in Southwest Michigan. Sediment cores were separated into consolidated and flocculent strata for analysis of percent organic matter, total sediment phosphorus (TP), and HCl-extractable iron (HCl~Fe). Sediment TP ranged from 110-3348 ugP/gdw, with an average of 1052 ugP/gdw.
