“…The constant 297.15 is 24°C scaled in absolute temperature. Simultaneous model fittings and determination of model parameters for Equations 2 and 3 were carried out using a Bayesian approach, where the prior distributions for the parameters were determined by averaging the mean and variances of estimates from previous studies (Fujimoto et al ,, ; Kokubu et al ; Vo et al ; Terada et al ,,).

“…It is of our great interest to evaluate and clarify site‐ and species‐specific response to environmental conditions. Our recent studies using a pulse amplitude modulated (PAM)‐ chlorophyll fluorometer, coupled with dissolved oxygen measurements, revealed the photosynthetic response to temperature and PAR of several freshwater and marine macroalgae (Fujimoto et al ,, ; Kokubu et al ; Vo et al ; Terada et al ,,). For instance, K. alvarezii from Vietnam yielded the highest maximum quantum yield (maximum photochemical efficiency of photosystem II, F v /F m ; Cosgrove & Borowitzka ) of 0.51 at 22.2°C (Terada et al ).…”

SUMMARY Knowledge concerning the effects of several abiotic factors on the physiology of carrageenophytes is essential both in ecological and economic standpoints, to ensure their sufficient supply for the sustainability of seaweed‐based industries. This paper presents the photosynthetic characteristics of farmed carrageenophytes, E ucheuma denticulatum and K appaphycus alvarezii [brown (BRN) and green (GRN) color morphotypes] from Sulawesi Utara (Sulawesi Island), Indonesia, as determined by examining their photosynthetic response across different temperatures and irradiances using dissolved oxygen measurements and pulse‐amplitude modulated fluorometer. Net photosynthesis–irradiance ( P – E ) curves at 26°C revealed that net photosynthetic rates of the three seaweeds gradually increased until the estimated saturation irradiances ( E k ) of 58 μmol photons m− 2 s−1 (49–68 μmol photons m− 2 s−1, 95% Bayesian prediction intervals; BPI) for E . denticulatum, and 158 and 143 μmol photons m− 2 s−1 (134–185 and 99–203 μmol photons m− 2 s−1, 95% BPI) for BRN and GRN K . alvarezii, respectively; and that no photoinhibition was observed at the highest irradiance of 1000 μmol photons m− 2 s−1. All seaweed samples exhibited photosynthetic tolerance to high PAR as shown by their recovery in maximum quantum yields (Fv / Fm ) following chronic exposures; as well as tolerance over a broad range of temperature, which is from 19 to 33°C for E . denticulatum, 20–29°C for BRN K . alvarezii, and 17–32°C for GRN K . alvarezii. Temperature responses of these carrageenophytes indicated that they were well‐adapted to the annual seawater temperatures in the cultivation site; however, they are also likely close to threshold levels for thermal inhibition, given the decline in Fv / Fm above 30°C.

The effect of irradiance and temperature on the photosynthesis and growth of a Vietnamese-cultivated red alga, Kappaphycus alvarezii, was determined by laboratory and field measurements. Dissolved oxygen sensors and pulse amplitude modulated (PAM) fluorometry were used for the measurements of photosynthetic efficiency. A Diving-PAM revealed that in situ measurements of the effective quantum yield (Φ PSII ) were negatively correlated with incident irradiance. Φ PSII decreased as irradiance increased at noon and recovered in the evening, suggesting photo-inhibition. A model of the net photosynthesis-irradiance (P-E) relationship determined in a laboratory experiment at 26°C revealed that the net photosynthetic rate quickly increased at irradiances below the estimated saturation irradiance of 154 μmol photons m −2 s −1 (95 % Bayesian credible interval (BCI) of 117-203 μmol photons m −2 s −1 ). Gross photosynthesis and dark respiration under the laboratory measurements were also determined over a range of temperatures (8-42°C), revealing that the gross photosynthetic rates of 8.0 (BCI 7.03-9.59) μg O 2 g ww −1 min −1 at 31.1 (BCI 30.2-32.0)°C, and the dark respiration rate increased exponentially from a low of 0.22 μg O 2 g ww −1 min −1 at 10°C to a high of 1.88 μg O 2 g ww −1 min −1 at 42°C. The estimated highest value of the maximum quantum yield (Φ PSII at 0 μmol photons m −2 s −1 = F v /F m ) determined with the Imaging-PAM and occurred at 22.2 (BCI 20.8-23.5)°C and was 0.51 (BCI 0.48-0.54).Relative growth rate (RGR) and the survival rate after 2 weeks of laboratory culture showed that the relatively high growth rates (ca. 1.5 %) occurred at 28 and 32°C; however, mortality was 100 % at 36°C. This species is considered to be well-adapted to the natural temperature range of study site; however, it is likely close to the marginal temperature conditions. Furthermore, daytime incident irradiance on the frond under fine clear sky might be too strong for the effective photosynthesis of this species, suggesting that optimum irradiance for gross photosynthesis with the minimum decline of Φ PSII seems to be much lower.
