Abstract

Critical questions regarding effects of rising atmospheric CO[sub 2] and climate change on forested systems include: Will shoot growth change in response to elevated CO[sub 2] and temperature . Will net carbon and water fluxes change in response to elevated CO[sub 2] and temperature Initial shoot growth and gas flux data are presented for Pseudotsuga menziesii seedlings continuously exposed for one year to target environments of ambient or ambient +200 ppm CO[sub 2], and ambient or ambient + 4[degrees]C air temperature in closed chambers. Changes in stem diameter, height, terminal shoot and bud length, are reported. Whole canopy and single branch level gas flux data used to calculate photosynthetic, respiration, and transpiration rates also are reported. The experiment is continuing so that longer-term impacts of CO[sub 2] and temperature on the seedlings can be determined and data obtained for process-based modeling of tree growth. The aboveground effects will be related to belowground processes to evaluate whole system responses to atmospheric CO[sub 2] and climate change.

Effects of CO[sub 2] and climate change on forest trees: TERA, a state-of-the-science research facility

Conference Waschmann, R; Jarrell, G; Johnson, M; ... - Bulletin of the Ecological Society of America; (United States)

The Terestrial Ecophysiological Research Area (TERA) is a facility being used to examine the effects of elevated CO[sub 2] and global climate change on Douglas fir (Pseudotsuga menziesii (Mirb) Franco) seedlings. TERA consists of 12 climate-controlled growth chambers (Terracosms) that are illuminated with natural sunlight. Terracosm environmental conditions continuously mimic diurnal and seasonal changes in ambient air temperature, dew point temperature, and CO[sub 2] concentration to [+-] 1.5[degrees]C, [+-] 5[degrees]C, and [+-] 20 ppm, respectively. The terracosms are extensively instrumented in order to examine above- and belowground processes. All sensors, analytical instruments, and data acquisition equipment required for independent operationmore »« less
Elevated CO{sub 2} reduces high temperature stress in yellow birch

Journal Article Wayne, P; Bazzaz, F; Reekie, E - Bulletin of the Ecological Society of America

We investigated the growth, architectural development, and physiology of yellow birch (Betula alleghaniensis) seedlings raised under two day/night temperature regimes (21/26{degrees}C and 26/31{degrees}C), and in ambient and elevated atmospheric CO{sub 2} concentrations (400 and 800 {mu}l 1-1). At the end of one year of growth, total seedling biomass was significantly reduced by high temperature, but stimulated by elevated CO{sub 2}. However, temperature-induced growth reductions were substantially lower in high (27%) vs. low (53%) CO{sub 2}, reflecting a significant CO{sub 2} x temperature interaction. While a number of physiological parameters were recorded throughout the growing season, including in situ leaf netmore »« less
Effects of CO[sub 2] and climate change on forest trees: The TERA project

Conference Rygiewicz, P; Tingey, D; Olszyk, D; ... - Bulletin of the Ecological Society of America; (United States)

Rising atmospheric CO[sub 2] and other greenhouse gas concentrations may lead to altered climates, which may dramatically affect forests. In 1993, Douglas fir seedlings were planted in sunlight, climate-controlled environmental chambers (Terracosms) at a new research facility (TERA). The Terracosm experiment imposes altered climate scenarios possible within approximately 50 years: two CO[sub 2] (ambient, and ambient + 200 ppm) and two temperature (ambient, and ambient + 4[degrees]) treatments. The elevated CO[sub 2] and temperature treatments are added continuously to current ambient levels to preserve natural climatic variability. Supporting experiments are underday in the Cascade Mountains, and in Observation and Manipulationmore »« less
Effects of elevated atmospheric carbon dioxide and temperature on soil respiration in Douglas fir seedling systems

Journal Article Lin, G; Ehleringer, J; Rygiewicz, P - Bulletin of the Ecological Society of America

We investigated the effect of CO{sub 2} enrichment and temperature increase on root respiration, litter decomposition, consumption of soil organic matter, and overall soil respiration. Douglas fir (Pseudotsuga menziesii) seedlings were being grown in the US EPA global climate change facility in Corvallis at two atmospheric CO{sub 2} concentrations and two temperatures. Soil-respired CO{sub 2} was collected for carbon and oxygen isotope analysis. Litter and new roots were also collected for carbon isotope analyses, and litter and root water were collected for oxygen isotope analyses. Isotope data were used to distinguish the sources of CO{sub 2} between root respiration, littermore »« less
