Picophytoplankton in Freshwater Ecosystems: The Importance of Small-Sized Phototrophs [PDF]
About 40 years have passed since the discovery of picophytoplankton; the present knowledge of the taxonomy, physiology and ecology of these tiny photoautotrophic cells offers new perspectives on the importance of the microbial contribution to global biogeochemical cycles and food webs.

Global Responses of Phytoplankton Size Structure to Marine Heatwaves
Abstract Marine heatwaves (MHWs) are receiving fast‐growing attention due to their devastating ecological and socioeconomic impacts under global warming. Despite studies on the response of phytoplankton abundance to MHWs, their effects on phytoplankton size structure (PSS), a crucial property of phytoplankton community, are poorly understood.

This study examined spatial and seasonal dynamics of phytoplankton communities in the Dakatia River, identifying 37 genera across six major taxonomic classes, with Bacillariophyceae being the most dominant. Seasonal peaks in phytoplankton abundance and diversity indices indicated higher richness and evenness during winter, while multivariate analyses ...

Air-sea fluxes of methanol, acetone, acetaldehyde, isoprene and DMS from a Norwegian fjord following a phytoplankton bloom in a mesocosm experiment [PDF]
The ocean's influence on volatile organic compounds (VOCs) in the atmosphere is poorly understood. This work characterises the oceanic emission and/or uptake of methanol, acetone, acetaldehyde, isoprene and dimethyl sulphide (DMS) as a function of ...

Abstract Eutrophication in the Baltic Sea has caused an imbalance in the inorganic nitrogen (N) to phosphorus (P) ratio, leaving excess phosphate (PO4) after the phytoplankton spring bloom that terminates after N depletion. Using monitoring data, we demonstrated that the PO4 concentration has continued to increase in the outermost Gulf of Finland ...

Blooms of filamentous cyanobacteria reduce zooplankton quality and pelagic food web efficiency
Abstract Cyanobacterial blooms in marine and freshwater ecosystems have increased in magnitude, frequency, and distribution worldwide during recent decades. Filamentous cyanobacteria are of unsuitable size for mesozooplankton feeding and of poorer nutritional quality than other phytoplankton taxa. The production and quality of higher trophic levels are

Microzooplankton grazing on phytoplankton in the basin of northern South China Sea and the two typical areas of the Northwest Pacific [PDF]
分别于2014年4月和6月在南海北部海盆、2014年12月及2015年3-5月分别在吕宋海峡东侧和黑潮亲潮合流的西北太平洋海域,通过显微镜计数微型浮游动物主要类群丰度,同时应用稀释法结合流式细胞(FCM)技术和高效液相色谱(HPLC)技术,重点探究浮游植物生长率和微型浮游动物摄食率的时空差异及与环境因子的关系,以及不同浮游植物类群的生长率和微型浮游动物的选择性摄食。获得以下主要结果: 春季南海北部海域表层微型浮游动物丰度平均值为2742±1210indL-1,生物量平均为6.30±4.09µ ...
