Grant history of an LTER site
Over the past century, Alaska has been warming twice as quickly as the global average, with large increases occurring in its interior boreal forests. This warmer, drier climate has triggered important changes to regional wildfire, pests and pathogen outbreaks, and permafrost thaw. The Bonanza Creek Long-Term Ecological Research (BNZ LTER) program will advance understanding of… Read more »
Grimm 9714833 This project is a long-term study of the Phoenix metropolitan area and fringing regions of central Arizona into which Phoenix is rapidly expanding. Objectives of this LTER program are to: 1) generate and test general ecological theory in an urban environment, 2) enhance understanding of the ecology of cities, 3) identify feedbacks between… Read more »
CAP-2 proposes to extend long-term study of central Arizona and metropolitan Phoenix, a desert region supporting agricultural and urban/suburban land uses while undergoing rapid urbanization and population growth. CAP studies human drivers and feedbacks of ecological change. Previous work concentrated on the central themes of urbanization patterns and processes altering the city’s ecological conditions and… Read more »
For more than three decades, the Long-Term Ecological Research (LTER) Program has supported fundamental ecological research that requires long time periods and large spatial scales at a coordinated network of more than two dozen field sites. Since 1998, the LTER Program has supported two sites in urban settings to explicitly examine the interactions among human… Read more »
Humans are becoming an increasingly urban species, pointing to the profound importance of understanding how urban ecosystems function. 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 LTER) includes scientists… Read more »
Humans are rapidly becoming an urban species. It is profoundly important, therefore, to understand urban ecosystems. Cities are consumers of energy and resources and producers of waste. They are also social networks that create innovation, efficiency, and solutions. The Central Arizona-Phoenix LTER Program (CAP) empowers researchers from the environmental and social sciences to study cities… Read more »
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 »
