Effect of elevated atmospheric CO/sub 2/ on plant communities. Final report
We have studied the effects of elevated atmospheric carbon dioxide on communities of colonizing annual plants, crop plants, and deciduous forest trees. We observe differential effects on different species with regard to growth, biomass, phenology, resource allocation, photosynthesis, water-use efficiency, flowering, and fruiting. We conclude that competitive relations among plants are likely to change as global atmospheric CO/sub 2/ increases, and that therefore there will be longterm changes in the composition of natural communities. More research will be necessary before any but the very broadest conclusions can be made about what direction these community changes are likely to take. 10 references, 9 figures.
