Their restriction to shallow marine environments suggests that photosynthesis was the primary means of organic matter production for these benthic communities.
It is the signature from land surfaces that will yield the most detectable evidence for photosynthesis.
Either the purple bacteria have acquired the photosynthesis genes recently by lateral gene transfer or selective pressure forced various species to retain these organizational patterns.
These hypotheses will be tested as additional genomic, biochemical and geological evidence sheds more light on the evolution of nitrogen fixation, photosynthesis and cyanobacteria.
Evidence presented above decreases the likelihood that alterations in canopy processes such as photosynthesis and transpiration are responsible for these changes at the forest edge.
Leaf structure (specific leaf area) modulates photosynthesis-nitrogen relations: evidence from within and across species and functional groups.
The leaves were not only used for photosynthesis measurement but also for repeated monitoring of herbivory rate.
After these immediate measurements, samples were then placed on ice and tested for active photosynthesis at various time intervals afterward.
