Abstract Micro-algae play important roles in primary production, nutrient cycling, and applied biotechnology. Mico-algae are phylogenetically, morphologically physiologically diverse often easy to grow cultures. Growth is the key parameter of viability crucial for survival situ efficiency vitro . Therefore, growth used eco-physiological experiments describe fundamental niche optimum conditions....

Atmospheric deposition of nutrients to the surface seawater may significantly affect marine phytoplankton growth. Two in situ bioassay experiments were performed East China Sea (ECS) by adding (N, P, and Si) atmospheric aerosols into seawater. Chlorophyll a (Chl a) concentrations largely enhanced simultaneous input N P with maximal increase 0.68–0.78 μg Chl per μmol addition. This increment was...

Abstract This study examines how salinity reduction triggers the response of three marine microalgae at molecular and unicellular levels in terms chemical, mechanical, behavioral changes. At lowest salinity, all microalgal species exhibited an increase membrane sterols behaved stiffer. The glycocalyx-coated Dunaliella tertiolecta was surrounded by a thick actin layer showed highest physiologica...

In the intense mucilage formation observed in Sea of Marmara 2021, Phaeocystis pouchetii (Prymnesiophyceae) together with Skeletonema costatum, Cylindrotheca closterium, Thalassiosira rotula (Bacillariophyceae), and Gonyaulax fragilis (Dinophyceae) were detected foamy surface layer, Chrysoreinhardia giraudii Nematochrysopsis marina (Chrysophyceae), which are known to produce filamentous benthic...

An understanding of the annual variations in phytoplankton community freshwater lakes, and drivers responsible for these variations, is essential lake management. In this study we collected analyzed seasonal samples assessed environmental variables Nansi Lake from 2011 to 2015, order identify dynamics main each phylum. The results showed that diversity followed cycles, which were interrupted by...
