Water relations in grassland and desert ecosystems exposed to elevated atmospheric CO2
Results suggest that the indirect effects of CO2 on plant and soil water relations may contribute substantially to experimentally induced CO2-effects, and also reflect local humidity conditions. Expand
Warming and free-air CO2 enrichment alter demographics in four co-occurring grassland species.
Analysis of life cycle stages showed that seed production, seedling emergence and establishment were important factors in the responses of the species to global changes, and the demographic approach was very useful in understanding the variable responses of plants to globalChanges. Expand
Constraints to nitrogen acquisition of terrestrial plants under elevated CO2.
The results suggest that, at the decennial timescale covered by FACE studies, N limitation of eCO2 -induced terrestrial productivity enhancement is associated with negative effects of e CO2 on plant N acquisition rather than with growth dilution of plant N or processes leading to progressive N limitation.

Past lessons and future prospects: plant breeding for yield and persistence in cool-temperate pastures
A major priority for breeding might be to revisit previously abandoned traits that affected the physiological performance of forage species, armed now with a capacity to monitor gene expression at the molecular level, and so unravel ⁄ control the G · E interactions that limited their benefits. Expand
Scaling methane emissions from vegetation.
The remarkable observation that methane is emitted directly by plants, and in an aerobic environment is reported, which would estimate plant emissions to comprise 11–46% of the current total annual methane emissions. Expand
Near‐term impacts of elevated CO2, nitrogen and fungal endophyte‐infection on Lolium perenne L. growth, chemical composition and alkaloid production
The biochemical responses of perennial ryegrass to elevated CO 2 are clearly modified by the presence of endophytic fungi. Expand
Direct effects of increasing carbon dioxide on pasture plants and communities
Little is known about community responses or about plant-herbivore dynamics at elevated C02, so confirmation of these responses will only be possible when data are available from long-term studies of grazed pasture at elevated CO2. Expand

An assessment of existing studies on CO2 and intraspecific variability is presented to illustrate the potential biological basis for differential plant response among crop lines and demonstrate that while technical hurdles remain, active selection and breeding for CO2 responsiveness among cereal varieties may provide one of the simplest and direct strategies for increasing global yields and maintaining food security with anthropogenic change.

Short and long-term effects of elevated CO2 on Lolium perenne rhizodeposition and its consequences on soil organic matter turnover and plant N yield
It is still unclear whether elevated CO 2 increases plant root exudation and consequently affects the soil microbial biomass. The effects of elevated CO 2 on the fate of the C and nitrogen (N)Expand
Effects of Elevated CO2 and Simulated Seasonal Changes in Temperature on the Species Composition and Growth Rates of Pasture Turves
White clover was growing most strongly during the period of greatest CO2 stimulation and consequently its growth was enhanced more than that of ryegrass; however, the cooler season growth of rYEGrass gives it a temporal niche which is little affected by CO2 and this may be important for ry EG stability if it is an inherently poor responder to CO2.
