Humankind is increasingly an urban species and urban ecosystems are therefore profoundly important. Cities are concentrated consumers of energy and resources and producers of various wastes, but they are also centers of social networks, innovation, efficiency, and solutions. The Central Arizona–Phoenix Long Term Ecological Research program (CAP V) is a research project that includes scientists… Read more »

This award will create a LTER-Long-Term Ecological Research site in the coastal upwelling biome of the California Current System. The research will focus on mechanisms leading to temporal transitions between different states of the pelagic ecosystem. Observations from the CalCOFI (California Cooperative Oceanic Fisheries Investigations) coastal ocean time series, currently in its 55th year, demonstrate… Read more »

The California Current Ecosystem (CCE) LTER site is a productive coastal upwelling biome structured by remote and local physical forcing, as well as biotic interactions in the ocean water column. The CCE site, building upon 60 years of extensive time-series measurements by CalCOFI, seeks to understand the mechanisms underlying transitions between different states of this… Read more »

Upwelling regions are some of the most productive ocean ecosystems. The study region of the California Current Ecosystem (CCE) LTER is the southern sector of the California Current System (CCS), a major upwelling biome where the 67-year California Cooperative Fisheries Investigations (CalCOFI) program provides essential information characterizing both natural climate variability and progressive changes. The… Read more »

Coastal upwelling regions are found along the eastern boundaries of all ocean basins and are some of the most productive ecosystems in the ocean. This award is supporting the California Current Ecosystem Long Term Ecological Research (CCE LTER) site in a major upwelling biome. It leverages the 73-year California Cooperative Oceanic Fisheries Investigations (CalCOFI) program… Read more »

This project represents the renewal of the Cedar Creek Natural History Area Long-Term Ecological Research project. Long-term observation and experimentation will be used to examine the controls of successional dynamics and spatial patterning in ecosystems at the prairie-forest boundary. The investigators will build on the detailed data record already accumulated in a series of permanent… Read more »

9411972 Tilman The Cedar Creek Natural History Area is important because of its location on the climatically and edaphically controlled boundary between prairie and forest. This “tension zone” between forest and prairies is highly sensitive to climatic variation and strongly impacted by edaphic factors, especially soil nitrogen availability fire frequency and by herbivores and predators….

Andrews LTER 1 and 2 programs consisted of long-term field experiments and observation programs on disturbance regimes, vegetation succession, trophic interactions, forest/stream interactions, and controls on primary production, decomposition, and nutrient cycling. These studies will be continued in LTER 3 (1991-1996). In addition, synthesis efforts, initiated in LTER 1 and 2, will be expanded greatly…. Read more »

Swanson 9632921 The central question guiding the HJ Andrews LTER is: How do land use, natural disturbances and climate change affect three key ecosystem properties: carbon dynamics, biodiversity, and hydrology? These three ecosystem properties are of high scientific and social interest and represent three rather different categories of ecological response to landscape patterns. The principle… Read more »

Harmon 0218088 The Andrews LTER program seeks to understand the long-term dynamics of forest and river ecosystems of the Pacific Northwest. The Central Question guiding Andrews LTER research is: How do land use, natural disturbances, and climate change affect three key sets of ecosystem services: carbon and nutrient dynamics, biodiversity, and hydrology? These ecosystem services… Read more »
