Grant history of an LTER site
In many parts of the world, including the southwestern United States, lands once covered by grass are starting to look like deserts. As scientists learn more about why this is happening, they are starting to realize that these lands do not always become deserts. There are other possible outcomes, such as habitats with lots of… Read more »
Dryland ecosystems occupy nearly half of the Earth’s land surface and provide goods and services for more than 1 billion people. The goal of the Jornada Basin Long Term Ecological Research (LTER) program is to understand what factors are most important to the ecology of drylands – what they look like and how they function….

In 1987 a Long-Term Ecological Research Project in Agricultural Ecology was initiated to examine basic ecological relationships in row crop ecosystems typical of the U.S. Midwest. The project’s original goal was to test the basic, long-term hypothesis that agronomic management based on knowledge of ecological interactions in cropping systems can effectively replace management based on… Read more »
9810220 Robertson Agricultural activities worldwide are carried out through a combination of biological and chemical management practices. The Kellogg Biological Station (KBS) Long-Term Ecological Research program has been conducting research since 1987 focusing on testing the hypothesis that agronomic management practices based on knowledge of ecological interactions can effectively replace management based on chemical subsidies….

Initiated in 1987, the Kellogg Biological Station LTER (KBS) examines basic ecological relationships in field crop ecosystems to better understand internal processes controlling productivity independently of external subsidies (e.g., fertilizers, pesticides). The initial goal remains the same: effectively substituting ecological knowledge and theory in the agronomic management of cropping systems for a reliance on chemically… Read more »
The Kellogg Biological Station (KBS) LTER project was initiated in 1987 and since then has provided experimental and observational research designed to understand the basic internal ecological relationships that control productivity of field crop ecosystems in North America, independent of external inputs such as pesticides and fertilizers. The project has combined comparative and experimental studies… Read more »
Agriculture is the dominant land use under direct management by people, and it is one of the biggest agents of global change, with far-reaching impacts on human welfare and the environment. The application of ecological knowledge to improve sustainable agricultural ecosystems remains a recognized grand challenge for environmental science. Since 1988, research at the W.K…. Read more »
Working farms cover much of the United States, providing food, feed, and biofuel to global markets. Changing weather patterns and land use are making it more difficult to manage agricultural lands for profit and environmental health. Midwestern field crop farmers are quick to note that changes in rainfall patterns are playing havoc with their management…. Read more »
Since 1989, scientists at the Kellogg Biological Station Long-Term Ecological Research program have been studying the ecology of agricultural systems. This research would extend that research to 40 years while adding to our knowledge of how plants, insects, microbes, soils, and climate interact to shape agricultural landscapes. Importantly, in the US Midwest where corn and… Read more »
A multidisciplinary study of fire, grazing and fire-grazing interactions on population, community and ecosystem properties will be continued on Konza Prairie, a native tallgrass prairie site in northeastern Kansas. The proposed research builds and expands upon a ten-year study of fire frequency effects on tallgrass prairie. Previous and proposed LTER efforts will continue to provide… Read more »
