[1] Seasonal coherence between satellite-derived phytoplankton parameters (chlorophyll a concentration (Chl) and phytoplankton bloom initiation time (BIT)), environmental variables (sea ice concentration, surface solar radiation, and wind speed), and climate patterns (El Niño 3.4, the Southern Annular Mode, the Pacific South America pattern, the semiannual oscillation, and the wave-3 stationary...

To better understand seasonal variation in phytoplankton community structure in the East China Sea (ECS), 4 research cruises were carried out between August 2009 and June 2011 over the continental shelf. Phytoplankton community structure and ambient seawater physicochemical parameters were examined. The phytoplankton community in the ECS was mainly composed of diatoms and dinoflagellates, with ...

We motivate and analyse a reaction-advection-diffusion model for the dynamics of a phytoplankton species. The reproductive rate of the phytoplankton is determined by the local light intensity. The light intensity decreases with depth due to absorption by water and phytoplankton. Phytoplankton is transported by turbulent diffusion in a water column of given depth. Furthermore, it might be sinkin...

We examined the potential effects of environmental variables, and their interaction, on phytoplankton community succession in spring using long-term data from 1992 to 2012 in Lake Taihu, China. Laboratory experiments were additionally performed to test the sensitivity of the phytoplankton community to nutrient concentrations and temperature. A phytoplankton community structure analysis from 199...

In this study, a global data set on size-fractionated chlorophyll distributions collected in the open ocean (depth >400 m) is used to investigate phytoplankton community size structure in relation to temperature and inorganic nutrient availability in an attempt to identify the individual and shared effects of these 2 factors. The macroecological patterns show an increase in the fraction of larg...

Understanding the mechanisms that determine how phytoplankton adapt to warming will substantially improve the realism of models describing ecological and biogeochemical effects of climate change. Here, we quantify the evolution of elevated thermal tolerance in the phytoplankton, Chlorella vulgaris. Initially, population growth was limited at higher temperatures because respiration was more sens...

Eukaryotic microplankton plays an important role in water biotic community and maintaining the stability of ecosystems. Environmental DNA metabarcoding provides opportunity to integrate traditional emerging approaches discover more new species, develop molecular indices that can be rapidly, frequently, robustly used quality assessments. In order examine assemblages eukaryotic lower reaches Qian...

Phytoplankton in coastal waters are important for the evaluation of either biodiversity or environmental impacts because this highly vulnerable ecosystem. Seasonal and annual changes phytoplankton community structure Quang Ngai during period 2015 to 2019 were analyzed assess diversity reveal possible causes these changes. A total 366 taxa belonging 10 classes identified throughout present study...

We motivate and analyze a reaction-advection-di usion model for the dynamics of a phytoplankton species. The reproductive rate of the phytoplankton is determined by the local light intensity. The light intensity decreases with depth due to absorption by water and phytoplankton. Phytoplankton is transported by turbulent di usion in a water column of given depth. Furthermore, it might be sinking ...

Phytoplankton is the basis for aquatic food webs and mirrors the water quality. Conventionally, phytoplankton analysis has been done using time consuming and partly subjective microscopic observations, but next generation sequencing (NGS) technologies provide promising potential for rapid automated examination of environmental samples. Because many phytoplankton species have tough cell walls, m...
