Grant history of an LTER site

LTER: Beaufort Sea Lagoons: An Arctic Coastal Ecosystem in Transition

This project will establish a new Long Term Ecological Research (LTER) site along the Alaskan Arctic coastline. Research based out of Utqiagvik (formerly Barrow), Deadhorse, and Kaktovik will address how changes in shoreline erosion and freshwater inflows to the coastal ocean over seasonal, annual, and longer timeframes influence near-shore food webs. Research will be conducted… Read more »

LTER: Seasonal Controls and Emergent Effects of Changing Land-ice-ocean Interactions on Arctic Coastal Ecosystems (BLE II)

This project continues the Beaufort Lagoon Ecosystems Long Term Ecological Research (BLE LTER) program. The BLE LTER was added to NSF’s network of LTER sites in 2017 and current work represents the second phase of this long-term effort. The project focuses on interactions between physical, chemical, and biological properties of nearshore ecosystems along Alaska’s northern-most… Read more »

Urban LTER: Human Settlements as Ecosystems: Metropolitan Baltimore from 1797 – 2100

For about 20 years, researchers with the Baltimore Long-Term Environmental Research (LTER) project have studied ecology within the city of Baltimore. When it started, the Baltimore LTER project was highly unusual because most ecologists were working in more natural environments. This was one of the very first urban ecology sites. A long-term approach was needed… Read more »

LTER: Baltimore Ecosystem Study Phase III: Adaptive Processes in the Baltimore Socio-Ecological System from the Sanitary to the Sustainable City

The Baltimore Ecosystem Study (BES) was initiated as an LTER project in 1997, designed to understand the controls and interactions of urban ecosystem structure and function. This project will continue that long-term line of research and will expand it to address 3 fundamental issues: 1) The spatial and temporal relationships of socio-economic, ecological, and physical… Read more »

LTER: Dynamic heterogeneity: Investigating causes and consequences of ecological change in the Baltimore urban ecosystem

Urban populations continue to expand around the world, highlighting the growing need for scientific information to deepen our understanding of ecological and social factors that influence the structure and function of urban ecosystems. A robust set of theories and models of cities as social-ecological systems is necessary to help cities adapt to changing conditions, and… Read more »

LTER: Baltimore Ecosystem Study: Synthesis of long-term studies of how multiple human and biophysical factors interact to drive ecological change of an urban ecosystem

For about 20 years, researchers with the Baltimore Long-Term Environmental Research (LTER) project have studied ecology within the city of Baltimore. When it started, the Baltimore LTER project was highly unusual because most ecologists were working in more natural environments. This was one of the very first urban ecology sites.

Long-term Studies of Ecosystem Response to Disturbance Along Environmental Gradients at Coweeta Hydrologic Laboratory

This project will continue long-term studies of response and recovery of Southern Appalachian forested ecosystems to disturbances. To understand and predict responses to current and emerging environmental problems requires an expansion of research perspective from a watershed to a landscape. The project will emphasize new studies along a complex environmental gradient with a continued emphasis… Read more »

Long-Term Studies of Disturbances as They Affect Ecological Processes in Landscapes of the Southern Appalachians

This research will continue investigations on the extent and complexity of natural and human-caused disturbances, and how they interact with ecological processes along environmental gradients in the landscape. This work builds upon extensive long-term studies of landscape processes in the southern Appalachians and spans four levels of resolution (plot, watershed, landscape and region) in the… Read more »

LTER: Consequences of Land Use Change in the Southern Appalachian Mountains

The Coweeta LTER Research Program has evolved since 1980 from a site-based to a site- and region-based project examining the effects of disturbance and environmental gradients on biogeochemical cycling, and the underlying watershed ecosystem processes that regulate and respond to those cycles. The objective for the proposed 2002-2008 research is to advance scientific understanding of… Read more »
