Grant history of an LTER site
9813061 LYONS The extreme environment of the McMurdo Dry Valleys will be the focus of a Long Term Ecological Research(LTER)project located approximately 100 km west of McMurdo Station, Antarctica. The dry valleys are among the most extreme deserts in the world. The perennially ice-covered lakes, ephemeral streams, and extensive areas of soil within the valleys… Read more »
The McMurdo Dry Valleys (MCM) LTER project focuses on aquatic and terrestrial ecosystems in a cold desert region of Antarctica. Located on the western coast of McMurdo Sound it forms the largest relatively ice-free area on the continent yet is still subject to extreme environmental conditions: perennially ice-covered lakes, ephemeral streams, extensive areas of exposed… Read more »

The McMurdo Dry Valleys (MDV) is a polar desert on the coast of East Antarctica, a region that has not yet experienced climate warming. The McMurdo Dry Valleys Long Term Ecological Research (MCMLTER) project has documented the ecological responses of the glacier, soil, stream and lake ecosystems in the MDV during a cooling trend (from… Read more »
The overall goal of the Jornada Basin Long Term Ecological Research Program is to understand and quantify the mechanisms that generate alternative natural and human-dominated states in dryland ecosystems, and to predict future states and their consequences for the provisioning of ecosystem services. Based on long-term databases beginning in 1858, research over the next six… Read more »
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 »
