Toxic Picoplanktonic Cyanobacteria—Review [PDF]

open access: yesMarine Drugs, 2015
Cyanobacteria of a picoplanktonic cell size (0.2 to 2.0 µm) are common organisms of both freshwater and marine ecosystems. However, due to their small size and relatively short study history, picoplanktonic cyanobacteria, in contrast to the ...

Freshwater autotrophic picoplankton: a review

open access: yesJournal of Limnology, 2002
Autotrophic picoplankton (APP) are distributed worldwide and are ubiquitous in all types of lakes of varying trophic state. APP are major players in carbon production in all aquatic ecosystems, including extreme environments such as cold ice-covered and ...

The planktonic food web in the Gulf of Naples based on the analysis of carbon and nitrogen stable isotope ratios

open access: yesMarine Ecology, EarlyView., 2023
Abstract Plankton play a key role in marine food webs by producing and transferring organic matter and energy to higher trophic levels. To define the trophic structure and interactions within the planktonic communities in the Gulf of Naples, we determined carbon and nitrogen stable isotope ratios in particulate organic matter (POM, <20 μm ...

Effects of the Coastal Uplift on the Kuroshio Ecosystem, Eastern Taiwan, the Western Boundary Current of the North Pacific Ocean

open access: yesFrontiers in Marine Science, 2022
The Kuroshio is the western boundary current of the North Pacific Ocean. In the subtropical region of eastern Taiwan, a coastal uplift of the isotherms has occurred.

Seasonal Dynamics of Lake Winnipeg’s Microbial Communities Reveal Aerobic Anoxygenic Phototrophic Populations Coincide with Sunlight Availability

open access: yesMicroorganisms, 2022
In this first comprehensive study of Lake Winnipeg’s microbial communities, limnetic and littoral euphotic zones were examined during each season from 2016 through 2020.

Eukaryotic versus prokaryotic marine picoplankton ecology [PDF]

open access: yesEnvironmental Microbiology, 2012
Summary Marine microorganisms contribute markedly to global biomass and ecosystem function. They include a diverse collection of organisms differing in cell size and in evolutionary history. In particular, microbes within the picoplankton are similar in size but belong to two drastically different cellular plans, the prokaryotes and ...

Diazotroph-Derived Nitrogen Assimilation Strategies Differ by Scleractinian Coral Species

open access: yesFrontiers in Marine Science, 2021
Reef-building corals generally thrive in nutrient-poor tropical waters, where among other elements, nitrogen (N) availability often limits primary productivity.

Distribution and seasonal variation of picoplankton in Sanggou Bay, China

open access: yesAquaculture Environment Interactions, 2016
Picoplankton abundance and biomass in Sanggou Bay, China, were investigated in 4 successive seasons (April, August and October 2011, January 2012). Different distribution patterns of picoplankton abundance and biomass were observed according to season ...

Comparative Metabarcoding and Metatranscriptomic Analysis of Microeukaryotes Within Coastal Surface Waters of West Greenland and Northwest Iceland

open access: yesFrontiers in Marine Science, 2020
Climate change alters environmental conditions that are expected to have a profound effect on the biodiversity, community composition, and metabolic processes of microeukaryotic plankton in Arctic and Subarctic coastal waters. The molecular biodiversity [

Light‐Driven and Nutrient‐Driven Displacements of Subsurface Chlorophyll Maximum Depth in Subtropical Gyres

open access: yesGeophysical Research Letters, 2023
The mechanism that determines the dynamics of subsurface chlorophyll maximum depth (zSCM) has long been debated. Although a coupling between zSCM and the top of nitracline (znit) has been widely observed in the open ocean, a co‐location of zSCM and an ...
