abstract = "The photosynthetic responses of 37 tropical seaweeds (14 Chlorophyceae, 5 Phaeophyceae and 18 Rhodophyceae) were measured in a Gilson Warburg Apparatus under a variety of light and temperature regimes. The brown algae Padina vickersiae and Sporochnus pedunculatus exhibited
the lowest saturation light intensity (263 E/m2/sec), while five green algae (Acetabularia crenulata, Cladophora coelothrix, Dictyosphaeria cavernosa, Monostroma oxyspermum and Codium repens) had the highest light optima (3,8434,258 E/m2/sec).
Overall, the Chlorophyceae exhibited the broadest range of light optima; in contrast, the Phaeophyceae primarily had low light optima, while several Rhodophyceae had higher light optima. The thermal optima for 34 seaweeds ranged from 1530\textdegreeC. Catoglossa leprierii, Botryocladia
occidentalis, Codium taylorii, Soliera tenera and Codium intertextum exhibited relatively broad thermal optima, with C. leprierii having the most eurythermal response. The Chlorophyceae exhibited thermal optima between 1530\textdegreeC, the Phaeophyceae between 1527\textdegreeC,
and most Rhodophyceae between 1824\textdegreeC. Few taxa, except for Cladophora coelothrix and Dictyosphaeria cavernosa, had broad physiological tolerances to both high temperature and light regimes. Overall, the Phaeophyceae exhibited the most restricted temperature and light
optima, while the Chlorophyceae and Rhodophyceae exhibited broader tolerances.",
