title: A Circumpolar Comparison of Tundra Response to Temperature Manipulation; A Synthesis of International Tundra Experiment Data

description: Synthesis of existing data from 26 circumpolar arctic and alpine sites regarding species response to a common temperature manipulation. The sites are part of the International Tundra Experiment (ITEX), a collaboration of arctic and alpine researchers. ITEX programs have been in place throughout the circumpolar arctic and temperate alpine since 1992 or 1993. ITEX investigators use a common experimental design, work with a common set of species, and monitor common parameters of the ecosystem and physical environment. ITEX investigators seek to understand how the same species located in different geographical areas respond to warming and natural climatic variability, and how changes in those species and their environments will affect overall ecosystem structure and function. A common assumption in ecological studies is that patterns of response in species (or other groupings such as functional types or ecosystems) can be directly extrapolated to the range of the species or type. Such an assumption is necessary if data are to be used in modeling and extrapolation studies. The ITEX data will allow us to explicitly test this assumption by examining variability in tundra responses at multiple sites over 4-5 years. We have compiled and integrated data sets from ITEX research sites in order to test hypotheses of tundra response at a global scale using meta-analysis techniques.

title: Trace gas flux data

description: The atmospheric concentrations of greenhouse gases such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) are increasing substantially. These increases are expected to result in global warming and changes in precipitation patterns, and may directly affect terrestrial ecosystems. Our understanding of the contemporary fluxes of these gases between the land and atmosphere is incomplete. There are large regions of the earth for which we have very little information on trace gas fluxes. Furthermore, for no region do we fully understand how global change, including land-use change, will affect gas fluxes.The United States Trace Gas Network(TRAGNET) is meant to accomplish the following two goals: Document contemporary fluxes of CO2, CH4 and N2O between regionally important ecosystems and the atmosphere Determine the factors controlling these fluxes and improve our ability to predict future fluxes in response to ecosystem and climate change.Part of this research is supported by the National Science Foundation.

title: Terrestrial Ecosystem Model (TEM) Dataset - data from 16 vegetation types worldwide

description: The Terrestrial Ecosystem Model (TEM) is a process-based model developed by staff at the Ecosystems Center, Marine Biological Laboratory, Woods Hole, Massachusetts, U.S.A. Data on pool sizes and fluxes of carbon (C) and nitrogen (N) from 16 field study sites in a wide range of biomes were used to calibrate the model. Ranging from tundra to tropical forest, but excluding wetlands, these data are collectively known as the"TEM data set". Because these NPP data already existed as a collection, but were previously not widely available in electronic form, they have been made available through the ORNL DAAC as a service to the ecosystem modelling community. The spreadsheet and text versions of the table below have been compiled from the appendix to McGuire et al. (1992). See this reference for further details of sources of the data. Mean annual values of carbon in vegetation (CV), nitrogen in vegetation (NV), carbon in soil (CS), nitrogen in soil (NS), and inorganic nitrogen in soil (NAV), are in g/m2 of either carbon or nitrogen. Values of gross primary productivity (GPP), net primary productivity (NPP), nitrogen uptake by vegetation (NUPTAKE), saturation response of NPP to nitrogen fertilization (NPPSAT), and the annual amount of nitrogen mobilized for production via recycling (NMOBIL) are in g/m2/yr. McGuire et al. (1992) assume that NPP = carbon in litter production = carbon in heterotrophic respiration and that NUPTAKE = nitrogen in litter production = net nitrogen mineralization (NETNMIN) during calibration of the TEM model.
