Inland Climate Change: Social and Ecological Sensitivities and Responses

Posted in Working Groups

Current plans call for implementing a 5-year manipulative experiment, focused on increasing and decreasing growing season rainfall amounts, across 15 sites in the central US. The rationale for a central US grassland focus includes: The stature of this biome that makes it amenable to such manipulations The presence of several LTER/NEON sites in the region… Read more »

Landscape Vulnerability and Resilience to Climate Change and Land Use Change

Posted in Working Groups

The central US grasslands can serve as a test-bed that will allow us to build on a legacy of past LTER research while testing basic ecological theory that can facilitate the identification of mechanisms explaining differences in the sensitivity of ecosystems to climate change. Results and understanding from this study should be valuable for making… Read more »

State Changes and Threshold Dynamics

Posted in Working Groups

A four-day workshop will use LTER data, including data from the EcoTrends project, to bridge the gap between the relatively mature theoretical understanding of thresholds and state changes in ecological systems and the emerging empirical databases that allow us to actually test models of state changes. Many of these changes represent “tipping points” or dramatic… Read more »

Development of a hydrochemical database – StreamchemDB

Posted in Working Groups

We are requesting Synthesis Working Group funds to support LTER participation in StreamchemDB. StreamchemDB is focused on aquatic chemistry data, and builds on former data synthesis projects ClimDB and HydroDB, all of which have been collaborative LTER-Forest Service cross-site synthesis and cyber-infrastructure projects.

Synthesis and Establishment of Guidelines Toward the Management of Next-Generation Sequence Data

Posted in Working Groups

Long-term ecological studies have expanded our view of microbial biology with the incorporation of long-term monitoring programs of diversity, plant and animal ecology, and decomposition processes in the context of global climate change. The full integration of meaningful cross-site ecological-genomic studies into LTER research will require either substantial new infrastructure or access to existing infrastructure… Read more »

Quantifying Uncertainty in Ecosystem Studies

Posted in Working Groups

The goal of this synthesis is to evaluate uncertainty in hydrologic inputs, outputs, and net hydrologic flux of major elements across small watersheds with diverse characteristics. The long-term goal of this project is to contribute to a cultural change in ecology that makes uncertainty analysis an accepted and expected practice in the construction of ecosystem… Read more »

Long-term Experiments in the LTER Network: Synthesis and Hypothesis Testing

Posted in Working Groups

We are requesting funds to assemble a working group of LTER scientists with extensive experience in conducting long-term experiments in the LTER Network, the skills and interest in synthetically interpreting the results of those experiments, and in using data from these studies to address new questions relevant to pressing global change issues.
