Long-Term Response of Plants at Barrow and Atqasuk to ITEX Warming Experiments

Task 5:
Integration & Synthesis
The project is working with others in the region to increase integration between projects. For example as part of NATEX Steve Oberbauer (Florida International University) is collecting carbon exchange and soil nutrients data to understand changes in ecosystem processes.
We are also working with John Gamon (California State University, Los Angeles) to better understand changes in NDVI (Normalized Difference Vegetation Index) throughout the season. It is hoped that the group will be able to continue and expand collaborative activities because they greatly enrich the core research.
The project is at the early stage of synthesizing the total plant temperature interaction. Many of the individual tasks described above have already been combined. For example, in Figure J stature of Luzula confusa (Task 2) is graphed against TDDsm (Task 1). Also, patterns of plant response (Task 3) are a combination of individual plant responses Task 2.
Future synthesis will include the combining of individual plant response (Task 2 & 3) with community change (Task 4) and plant response data such as phenology with ecosystem data such as carbon exchange and NDVIs.
