Grant history of an LTER site
The Arctic is warming more rapidly than the rest of the planet. Thawing of previously frozen soils will have consequences for society through alteration of carbon emissions. Most previous research has focused on how Arctic ecosystems respond to average warming trends. There is however very little research on variability of environmental conditions within that average… Read more »
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 »
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 »
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 »
The Baltimore Ecosystem Study (BES) was initiated as an LTER project in 1997, designed to understand the controls on urban system structure and function, and how structure and function of the urban ecosystem affect one another. The proposed research will expand the first phase BES work by addressing three fundamental questions: 1) How do the… Read more »
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 »
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 »

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 »
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 »
