Arctic marine photoautotrophic picoplankton

Marine Ecology Progress Series, 1985
Abundance and activity of picoplankton (here defined as cells passing a 1 pm Nucleporem screen) were studied in northern Foxe Basin, eastern Canadian Arctic. Substantial proportions (10 to 70 %) of the chlorophyll a content, ribulose-1,5-bisphosphate carboxylase activity (RuBPC, E.C.

Diversity of Microbial Eukaryotes Along the West Antarctic Peninsula in Austral Spring

Frontiers in Microbiology, 2022
During a cruise from October to November 2019, along the West Antarctic Peninsula, between 64.32 and 68.37°S, we assessed the diversity and composition of the active microbial eukaryotic community within three size fractions: micro- (> 20 μm), nano ...

Phosphorus Acquisition Strategies Among Phytoplankton and Free-Living Bacterial Communities in the Baltic Proper. [PDF]

Environ Microbiol Rep
Phosphorus is a key element for cellular functions and poses significant challenges for planktonic microbial communities under limited availability. Metagenomics highlighted that heterotrophic bacteria predominantly relied on phosphate scavenging while eukaryotic phytoplankton primarily utilized membrane remodelling to cope with limited phosphorus ...

Seasonal modulation of mesoscale processes alters nutrient availability and plankton communities in the Red Sea [PDF]

, 2019
Hydrographic and atmospheric forcing set fundamental constraints on the biogeochemistry of aquatic ecosystems and manifest in the patterns of nutrient availability and recycling, species composition of communities, trophic dynamics, and ecosystem ...

Arsenolipids in Cultured Picocystis Strain ML and Their Occurrence in Biota and Sediment from Mono Lake, California

Life, 2020
Primary production in Mono Lake, a hypersaline soda lake rich in dissolved inorganic arsenic, is dominated by Picocystis strain ML. We set out to determine if this photoautotrophic picoplankter could metabolize inorganic arsenic and in doing so form ...

Marine protist diversity in European coastal waters and sediments as revealed by high-throughput sequencing [PDF]

, 2015
International audienceAlthough protists are critical components of marine ecosystems, they are still poorly characterized. Here we analysed the taxonomic diversity of planktonic and benthic protist communities collected in six distant European coastal ...

Diel Protein Regulation of Marine Picoplanktonic Communities Assessed by Metaproteomics

Microorganisms, 2021
The diel cycle is of enormous biological importance in that it imposes temporal structure on ecosystem productivity. In the world’s oceans, microorganisms form complex communities that carry out about half of photosynthesis and the bulk of life ...

Effect of zooplankton-mediated trophic cascades on marine microbial food web components (bacteria, nanoflagellates, ciliates) [PDF]

, 2009
To examine the grazing effects of copepod-dominated mesozooplankton on heterotrophic microbial communities, four mesocosm experiments using gradients of zooplankton abundance were carried out at a coastal marine site.
