Long Term Ecological Research (LTER) Network
This site provides an in-depth overview of completed and on-going ecological research projects, including professional papers and research data. The studies include topics such as hydrology, metabolic rate of ecosystems, global change research, and climate data. Currently there are 24 LTER sites located in various ecosystems across the globe, from Antarctica to Alaska. This project is supported by the National Science Foundation (NSF) and involves research sites in 21 countries. Within the LTER site links can be found to learn more about international ecological research programs and ecological programs for schoolchildren. A primary goal of these projects is to further the study of environmental systems across a variety of temporal and spatial scales. Documenting long term ecosystem studies aids in the recognition and control of ecological problems. Project areas include: primary ecosystem production, variations in trophic structures, accumulation and decomposition of organic matter, soil nutrient movement, groundwater and surface water movement, as well as documentation of overall ecological disturbances. This site also includes links for international projects and ecological study projects for use in educational systems.
