Carbon cycling processes in ecosystems are generally believed to be well understood. Carbon, hydrogen, oxygen and other essential elements are chemically converted from inorganic to organic compounds primarily in the process of photosynthesis. Secondary metabolic processes cycle carbon in and among organisms and carbon is ultimately released back to the environment as CO2 by respiratory processes. Unfortunately, our understanding of this cycle was determined under the assumption that the… 
The impact of rising CO2 on ecosystem production
A fundamental property of green plants is that the rate of photosynthesis is dependent in the ambient CO2 concentration. There is overwhelming experimental evidence that this effect increases plant
Modelling stimulation of plants and ecosystem response to present levels of excess atmospheric CO2
Rising atmospheric CO 2 concentrations (16-26% above the preindustrial value) along with other anthropogenically released nutrients (especially nitrogen as well as phosphate compounds) may already
Biomass Partitioning and Resource Allocation of Plants from Mediterranean-Type Ecosystems: Possible Responses to Elevated Atmospheric CO2
The importance of allocation in determining whole-plant responses to CO2 is discussed, some of the general characteristics of woody plants from Mediterranean-type ecosystems that may influence their sensitivity to increased CO2 are reviewed, and some modeling approaches are applied to consider how biomass partitioning and resource allocation in Mediterranean plants might influence their responses to elevated CO2.
Biological methanogenesis and the CO2 greenhouse effect
It is well established that plants tend to increase net photosynthesis under increased carbon dioxide. It is also well established that a large fraction of atmospheric methane is produced by
Carbon Sequestration in Terrestrial Ecosystems
Global climate change has already had observable effects on the environment. For instance glaciers have shrunk, ice on rivers and lakes is breaking up earlier, lands are deteriorating, plant and
Effects of elevated CO2 on nutrient cycling in a sweetgum plantation
The effects of elevated CO2 on nutrient cycling and selected belowground processes in the closed-canopy sweetgum plantation were assessed as part of a free-air CO2 enrichment (FACE) experiment at Oak
Tree responses to rising CO2 in field experiments: implications for the future forest
Experiments with trees in open-top chamber experiments have provided data on longer-term, larger-scale responses of trees to elevated CO2 under field conditions, confirmed some of the conclusions from previous seedling studies, and challenged other conclusions.
Response of vegetation to rising carbon dioxide: Photosynthesis, biomass, and seed yield of soybean
Elevated carbon dioxide throughout the lifespan of soybean causes an increase in photosynthesis, biomass, and seed yield. A rectangular hyperbola model predicts a 32% increase in soybean seed yield
Elevated CO2 studies: past, present and future
Increasing concentrations of atmospheric CO(2) are predicted to impact both current and future ecosystems. Elevated CO(2) is also predicted to affect biological processes at many levels of


The increasing CO2 concentration in the atmosphere and its implication on agricultural productivity
The increasing concentration of CO2 in the atmosphere should result in a general increase in the net primary productivity of most cultivated species and forest species, assuming no counterproductive
Growth and feeding response of Pseudoplusia includens (Lepidoptera:Noctuidae) to host plants grown in controlled carbon dioxide atmospheres
The impact of herbivores may increase as the level of atmospheric carbon dioxide rises, and leaves of soybean plants grown under three carbon dioxide regimes were fed to soybean looper larvae, which altered the leaf content of nitrogen and water and to the leaf-specific weight.
Potential effects of global atmospheric CO2 enrichment on the growth and competitiveness of C3 and C4 weed and crop plants.
Research report: Mathematical growth analysis techniques were used to determine the effects of carbon dioxide on the growth and biomass partitioning in corn (zea mays), itchgrass (Rottbiellia exalata
Influence of water table and atmospheric CO/sub 2/ concentration on the carbon balance of arctic tundra
Carbon balance of intact arctic tundra microcosms (soil cores with vegetation) has been shown to be sensitive to small changes in water table. The persistence of the effect of water table on CO/sub
Carbon dioxide enrichment and water stress interaction on growth of two tomato cultivars
Summary If atmospheric carbon dioxide concentration continues to increase, plant growth and crop yield could be affected. New Yorker and Better Boy cultivars of tomato (Lycopersicon esculentum) were
Field Response of Photosynthesis to CO"2 Enhancement in Ponderosa Pine
Net photosynthesis was determined by CO2 analysis for Pinus ponderosa Laws. in situ in the San Bernardino Mountains of southern California. Leafy shoots were maintained in cuvettes under ambient and
Elevated Carbon Dioxide Concentrations and Whole Plant Senescence
The effects of lifetime exposures to elevated CO/sub 2/ levels in three native winter annual plant species on biomass accumulation, induction of flowering, leaf senescence, and death of whole plants are concerns.
The Relationship Between the Rates of Carbon Transport and of Photosynthesis in Tomato Leaves
The rate of carbon transport based on the carbon balance over a 6 -h period from a mature tomato leaf was measured over a range of net photosynthetic rates from 0-1 to 4-9 mg C dm-2 h_1 under light
Effects of CO2 enrichment on growth and photosynthesis in Desmodium paniculatum
The depression in photosynthetic rates on a leaf area basis of plants exposed to CO2 enrichment was correlated with increased starch accumulation and reduced grana formation in chloroplasts of leaves continuously exposed to high CO2 concentrations.
Effects of Temperature and CO(2) Enrichment on Carbon Translocation of Plants of the C(4) Grass Species Echinochloa crus-galli (L.) Beauv. from Cool and Warm Environments.
Overall, plants from Québec had a higher ( 11)C activity in leaf phloem and a higher percentage of (11)C exported, whereas these northern plants had lower turnover time and smaller pool size than plants from the southern population.
