“…This negative effect of both drivers, i.e. nutrients (linked to AI) and temperature (linked to MHWs), over long-term scales contrast with a recent meta-analysis which have shown that neither experimental increases in P inputs nor warming significantly affected Chl a production in coastal regions, estuaries or the open ocean (Wu et al, 2021). Based on our long-term results concerning the effects of Saharan dust-deposition events and MHWs, and contrasting findings in the literature (nutrients and warming) over mid-term scales, we cannot disregard the possibility that additional environmental drivers (e.g.…”

“…What is more, the clearer water body in the sampling site during high tide may also benefit the growth of phytoplankton cells, but this effect on the Chl a biomass would be eliminated in such an hourly scale. The nutrients concentration also plays a pivotal role in modulating phytoplankton growth and even blooms [ 47 ], but such a nutrient-induced activation for cell growth could not explain the Chl a being so altered in an hourly scale either [ 48 ]. Finally, the small cell-sized phytoplankton prevailed in the experimental area, consistent with previous studies [ 17 , 27 , 28 ].…”

Photosynthetic Characteristics of Smaller and Larger Cell Size-Fractioned Phytoplankton Assemblies in the Daya Bay, Northern South China Sea

Cell size of phytoplankton is known to influence their physiologies and, consequently, marine primary production. To characterize the cell size-dependent photophysiology of phytoplankton, we comparably explored the photosynthetic characteristics of piconano- (<20 µm) and micro-phytoplankton cell assemblies (>20 µm) in the Daya Bay, northern South China Sea, using a 36-h in situ high-temporal-resolution experiment. During the experimental periods, the phytoplankton biomass (Chl a) in the surface water ranged from 0.92 to 5.13 μg L−1, which was lower than that in bottom layer (i.e., 1.83–6.84 μg L−1). Piconano-Chl a accounted for 72% (mean value) of the total Chl a, with no significant difference between the surface and bottom layers. The maximum photochemical quantum yield (FV/FM) of Photosystem II (PS II) and functional absorption cross-section of PS II photochemistry (σPS II) of both piconano- and micro-cells assemblies varied inversely with solar radiation, but this occurred to a lesser extent in the former than in the latter ones. The σPS II of piconano- and micro-cell assemblies showed a similar change pattern to the FV/FM in daytime, but not in nighttime. Moreover, the fluorescence light curve (FLC)-derived light utilization efficiency (α) displayed the same daily change pattern as the FV/FM, and the saturation irradiance (EK) and maximal rETR (rETRmax) mirrored the change in the solar radiation. The FV/FM and σPS II of the piconano-cells were higher than their micro-counterparts under high solar light; while the EK and rETRmax were lower, no matter in what light regimes. In addition, our results indicate that the FV/FM of the micro-cell assembly varied quicker in regard to Chl a change than that of the piconano-cell assembly, indicating the larger phytoplankton cells are more suitable to grow than the smaller ones in the Daya Bay through timely modulating the PS II activity.

“…Phytoplankton experiencing nutrient limitations are compelled to adapt to the warming of seawater. The increase in temperatures has the potential to expedite the absorption of nutrients by phytoplankton, as evidenced by studies conducted by Berges et al, 2002;Wu et al, 2021 andWei et al, 2022. The presence of the coastal nuclear power plant (NPP) in SMB plays a significant role in this phenomenon, as NPPs produce substantial quantities of warm water effluent (Hu, 2004), thereby substantially raising the temperature of the surrounding aquatic environment (Langford, 1990;Krishnakumar et al, 1991;Zhang et al, 2023).…”

“…Phytoplankton, as the primary producer in aquatic ecosystems, play a crucial role in the microbial food web due to their ability to utilize nutrients and fix carbon (Cloern and Dufford, 2005;Zhou et al, 2008;Garmendia et al, 2011). The impact of anthropogenic nutrient inputs and global warming on marine phytoplankton has been significant (Novak et al, 2019;Wu et al, 2021). In coastal ecosystems across the globe, such as the East China Sea, the discharge of wastewater from tributaries has resulted in frequent harmful algal blooms (HABs) and subsequent fish mortality.…”

“…Coastal waters exhibit the greatest susceptibility to the impacts of human activities. Given the intricate and diverse nature of anthropogenic pressure (Borja et al, 2015), the manifestations and magnitude of these effects can differ significantly across geographical locations, and even within the same area over time (Wu et al, 2021;Gao et al, 2022;Wei et al, 2022). Hence, this study uses a systematic analysis treating the temporal data as various groups to describe the shift in phytoplankton composition, abundance, and response to environmental changes in four continuous seasons in Sanmen Bay.…”

In the context of global change, the stressors of warming and eutrophication have significant ecological implications in coastal waters. In order to examine the diversity of phytoplankton and its relationship with water quality, we conducted a survey of phytoplankton community compositions and their correlation with environmental changes over four seasons in a eutrophic bay located in the East China Sea. Through a systematic analysis, we identified diatoms and dinoflagellates as the primary dominant groups, with the species Skeletonema costatum, Skeletonema marinoi, Biddulphia sinensis, Thalassiosira eccentrica, Leptocylindrus danicus, Coscinodiscus oculus-iridis, Coscinodiscus jonesianus, and Chaetoceros knipowitschi as the most abundant species in all seasons. Significant seasonal alterations were observed in both environmental settings and phytoplankton species richness, dominance, and abundance. The phytoplankton community varied in its response to diverse aquatic environments and was principally affected by temperature, silicic acid concentrations, and suspended solids. Elevated temperatures were found to promote an increase in phytoplankton abundance. However, no clear evidence of diatom and dinoflagellate succession in relation to N:P ratio was observed across seasons. Water quality analysis illustrated that the majority of the study area exhibited a mid-eutrophic with severe organic pollution. The abundance of phytoplankton was significantly influenced by eutrophication and organic pollution. The accelerated warming process related to coastal nuclear power plants and nutrient regime alterations significantly affect the temporal shift of the phytoplankton community. These findings contribute valuable insights into the effects of eutrophic environments on the structure of phytoplankton communities in coastal aquatic systems.
