Cross site investigation using LTER Data.

Regulation of Organic Matter Preservation in Soils and Sediments

The workshop, “Scoop on Dirt” was held to compare soil organic matter (SOM) data and elicit a dialogue among estuarine wetland scientists from the eastern U.S., Gulf and Pacific coasts. The workshop, organized by Chris Craft, was held in conjunction with the Estuarine Research Federation meeting. Approximately 50 participants attended, including a core group of scientists (Jim Morris-PIE, Linda Blum, Bob Christian, Iris Anderson-VCR, Chris Craft-GCE, Randy Chambers-FCE) from coastal NSF LTER sites.

Scaling From Plots to Landscapes and Regions: Relevance of Landscapes to Current Issues in Ecology

The workshop was held at the H.J. Andrews LTER site near Blue River Oregon on May 21 and 22, 2001 with support from the LTER Network Office. Twenty people attended, including participants from Brazil, Hungary and Korea. The workshop was intended to promote data exchange between the remote sensing community — which has begun to produce global land cover, leaf area index, and net primary production products — and the field sites where relevant validation data is being produced.

Causes and Consequences of Invasive Species; Past and Future Contributions of the LTER Network

In this country invasive species are viewed with more concern than are genetically modified organisms. While this view may change, the scientific issues associated with invasive species strongly overlap and occasionally are identical to those of genetically modified organisms. Vulnerability of native species to the introduction of novel genetic material, including swamping of gene pools, competitive and trophic effects, and patterns of spread are a few of the scientific issues common to both biological invasions and the release of genetically modified organisms.
