Abstract In situ measurements of seagrass photosynthesis in relation to inorganic carbon (Ci) availability, increased pH and an inhibitor of extracellular carbonic anhydrase were made using an underwater pulse amplitude modulated (PAM) fluorometer. By combining the instrument with a specially designed Perspex chamber, we were able to alter the water surrounding a leaf without removing it from the growing plant. Responses to Ci within the chamber showed that subtidal plants of the seagrasses… Expand
Mechanisms of bicarbonate use influence the photosynthetic carbon dioxide sensitivity of tropical seagrasses
The photosynthetic bicarbonate (HCO { ) use properties of three widely distributed tropical seagrasses were compared using a series of laboratory experiments. Photosynthetic rates of ThalassiaExpand
In situ Photosynthetic Activities and Associated Biogeochemical Changes in Three Tropical Seagrass Species
Tropical seagrasses experience considerable spatio-temporal changes with light and other biogeochemical conditions and adopt species-specific acclimatization strategies. Variation inExpand
Interspecific variation in photosynthesis and respiration balance of three seagrasses in relation to light availability
C. rotundata has the potential to inhabit the deepest water, although its realized distribution range is shallower than that of C. serrulata, suggesting that other factors limit the depth range of C., which probably has the lowest minimum photon requirement of the 3 species. Expand
Buffer sensitivity of photosynthetic carbon utilisation in eight tropical seagrasses
Six of the eight seagrass species investigated except Cymodocea serrulata were sensitive to 50 mM TRIS buffer of the same pH as the natural seawater in which they grew, indicating that part of the 1997 results for the same species were due to a buffer effect on net photosynthesis. Expand
Daily variation patterns in seagrass photosynthesis along a vertical gradient
The photosynthetic parameters of Z. noltii revealed that this plant species exhibits sun- and shade-type responses in its upper and lower verti- cal distribution limits, respectively, and suggests that this species is strongly light-limited. Expand
Light Levels Affect Carbon Utilisation in Tropical Seagrass under Ocean Acidification
Light availability influenced productivity responses to DIC enrichment, via both carbon fixation and acquisition processes, highlighting the role of water quality in future responses to OA. Expand
Use of light and inorganic carbon acquisition by two morphotypes of Zostera noltii Hornem
The affinity for dissolved inorganic carbon (DIC) and the mechanisms to use HCO3 as a source of DIC for photosynthesis were investigated in two morphotypes of Zostera noltii Hornem, suggesting the existence of a positive interactive effect between DIC and PFR. Expand
Responses of three tropical seagrass species to CO2 enrichment
While seagrasses can be carbon-limited and productivity can respond positively to CO2 enrichment, varying carbon allocation strategies amongst species suggest differential growth response between species. Expand
Uptake and resource allocation of inorganic carbon by the temperate seagrasses Posidonia and Amphibolis
Uptake of carbon by the seagrass complex (leaves, roots, phytoplankton and epiphytes) was affected by both season and species and carbon uptake by the Amphibolis complex was higher than in the Posidonia complex. Expand
Inorganic carbon utilization in marine angiosperms (seagrasses).
The revelation that seagrass photosynthesis is sensitive to buffers as well as to physical perturbations, has led to new experiments in which initial pH values are set by appropriate HCO3-/CO32-ratios, and/or O2 measurements on leaf pieces are replaced with pulse amplitude-modulated fluorometry on whole, attached leaves, often in situ.
