Abstract. Shallow tropical marine environments are likely to experience future water temperatures that will challenge the ability of life to survive. Changes in temperature and irradiance during tidal cycles in the Tanjung Rhu estuary, Langkawi, Malaysia in 2007 did not significantly affect the benthic diatom communities, although, higher photosynthetic parameters, such as maximum relative electron transport rate (rETRmax), photosynthetic efficiency (α), maximum quantum yield (F_v/F_m) and effective quantum yield (∆F/F_m'), were recorded at high tide when the temperatures were lower. However, when benthic diatoms were experimentally exposed to irradiances of 1800 µmol photons m⁻² s⁻¹, they were only able to photosynthesize at temperatures

热带海洋底栖硅藻暴露于高辐照度和高温下的响应

摘要。浅热带海洋环境可能会遇到未来的水温，这将挑战生命的生存能力。尽管较高的光合参数，例如最大相对电子传递速率（rETRmax），光合效率（α），较高的光合参数，但2007年在马来西亚兰卡威的丹绒鲁河口的潮汐周期中温度和辐照度的变化并未显着影响底栖硅藻群落。当温度较低时，在涨潮时记录最大量子产率（F _v / F _m）和有效量子产率（ΔF/ F _m'）。但是，当底栖硅藻实验性地暴露于1800 µmol光子m ^-2  s ^-1时，他们只能在温度下光合作用
