| 英文摘要 | The effects of seawater temperature on the physiological performance of three Halimeda species were studied for a period of 28 d. Five treatments were established for Halimeda cylindracea, Halimeda opuntia and Halimeda lacunalis, in triplicate aquaria representing a factorial temperature with 24 degrees C, 28 degrees C, 32 degrees C, 34 degrees C and 36 degrees C, respectively. The average F-v/F-m of these species ranged from 0.732 to 0.756 between 24 degrees C and 32 degrees C but declined sharply between 34 degrees C (0.457 +/- 0.035) and 36 degrees C (0.122 +/- 0.014). Calcification was highest at 28 degrees C, with net calcification rates (G(net)) of (20.082 +/- 2.482) mg/(g center dot d), (12.825 +/- 1.623) mg/(g center dot d) and (6.411 +/- 1.029) mg/(g center dot d) for H. cylindracea, H. opuntia and H. lacunalis, respectively. Between 24 degrees C and 32 degrees C, the specific growth rate (SGR) of H. lacunalis (0.079%-0.110% d(-1)) was lower than that of H. cylindracea (0.652%-1.644% d(-1)) and H. opuntia (0.360%-1.527% d(-1)). Three Halimeda species gradually bleached at 36 degrees C during the study period. Malondialdehyde (MDA) and proline levels in tissues of the three Halimeda were higher in 34-36 degrees C than those in 24-32 degrees C. The results indicate that seawater temperature with range of 24-32 degrees C could benefit the growth and calcification of these Halimeda species, however, extreme temperatures above 34 degrees C have negative impacts. The measured physiological parameters also revealed that H. cylindracea and H. opuntia displayed broader temperature tolerance than H. lacunalis. |
