Journal ArticleDOI
Influence of increasing carbon dioxide concentration on the photosynthetic and growth stimulation of selected C4 crops and weeds
Lewis H. Ziska,James A. Bunce +1 more
TL;DR: Data from this study indicate that C4plants may respond directly to increasing CO2concentration, and in the case of some C4weeds, may show photosynthetic increases similar to those published for C3species.
Journal ArticleDOI
Acclimation of photosynthesis to temperature in eight cool and warm climate herbaceous C3 species: Temperature dependence of parameters of a biochemical photosynthesis model
TL;DR: Differences in the temperature response of photosynthesis were more related to variation in theTemperature dependencies of Jmax and VCmax than to the ratio of their normalized values.
Journal ArticleDOI
Elevated atmospheric CO2 concentration and temperature across an urban–rural transect
TL;DR: In this paper, a transect was established from Baltimore city center (Urban site), to the outer suburbs of Baltimore (suburban site) and out to an organic farm (rural site). At each site a weather station was set-up to monitor environmental variables for 5 years.
Journal ArticleDOI
Predicting the impact of changing CO2 on crop yields: some thoughts on food
Lewis H. Ziska,James A. Bunce +1 more
TL;DR: Improved projections of future food supply could be achieved by better characterization of the biotic/abiotic uncertainties associated with projected changes in CO(2) and climate and incorporation of these uncertainties into current crop models.
Journal ArticleDOI
Does transpiration control stomatal responses to water vapour pressure deficit
TL;DR: In this paper, three types of observations were used to test the hypothesis that the response of stomatal conductance to a change in vapour pressure deficit is controlled by whole-leaf transpiration rate or by feedback from leaf water potential.
