A Cross-Site Synthesis of Biotic and Abiotic Agents of Decomposition and SOM Dynamics in LTER Sites

To develop the framework of a synthesis paper to Soil Biology & Biochemistry.To review and critique the Integrated Research Challenges (IRC) proposal draft on the DIRT (Detritus Input and Removal Treatments) Intersite decomposition project (Knute Nadelhoffer, lead PI ).To review and critique the QIEB (Quantitative Integrated studies in Experimental Biology) proposal on the theoretical aspects of energetics and nutrient cycling of bacterial and fungal feeders in detrital foodwebs across a range of sites, some in the Network, including SGS and CWT, plus Wind Cave National Park (John Moore and Da

Scaling Carbon Flux to the Site Level in the Context of Validating Products from Earth Observing Satellites

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.

The Long-term Intersite Decomposition Experiment Team (LIDET)

Although numerous short-term experiments have been used to develop conceptual and simulation models of decomposition, very little is known about the later stages of this process. Exclusion of this later stage has led, at best, to incomplete understanding of ecosystem carbon and nitrogen dynamics. We propose a working group to examine the wealth of litter and decomposition data that has been produced by several recent long-term field experiments.

East Asia-Pacific Organic Matter Decomposition Processes Workshop

The workshop was designed as a pre-meeting for future collaboration of a multi-site organic matter decomposition experiment in the East Asia-Pacific region. The meeting and discussion among potential site collaborators worked towards a successful regional cross-site comparison study. The Taiwan Ecological Research Network (TERN) took the responsibility to organize, host and conduct this workshop and the follow-up on the decomposition field experiment and to publish the group results. Workshop funds were supported, in part, from the ILTER network.
