Arctic LTER: Climate Change and Changing Disturbance Regimes in Arctic Landscapes

This award supports the fifth phase of the Long Term Ecological Research Site (ARC LTER) at Toolik Lake, AK. The arctic region has warmed significantly over the past 30 years and arctic lands and freshwaters are already changing in response. The changes include a general “greening” of the arctic landscape, changes in species distributions and… Read more »

LTER: The Role of Climate Variability in Controlling Arctic Ecosystem Function

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 »

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 »
