Answer» Underwater photosynthesis of submerged plants – recent advances and methods Ole Pedersen1,2,3*, TIMOTHY D. Colmer3 and Kaj Sand-Jensen1 1The Freshwater Biological Laboratory, Department of Biology, University of Copenhagen, Hillerød, Denmark 2Institute of Advanced Studies, The University of Western Australia, Crawley, WA, Australia 3School of Plant Biology, The University of Western Australia, Crawley, WA, Australia We describe the general background and the recent advances in research on underwater photosynthesis of leaf SEGMENTS, whole communities, and plant dominated aquatic ecosystems and present contemporary methods tailor made to quantify photosynthesis and carbon FIXATION under water. The majority of studies of aquatic photosynthesis have been CARRIED out with detached LEAVES or thalli and this selectiveness influences the perception of the regulation of aquatic photosynthesis |
