[HTML][HTML] Diversity of pico-to mesoplankton along the 2000 km salinity gradient of the Baltic Sea

YOO Hu, B Karlson, S Charvet… - Frontiers in …, 2016 - frontiersin.org
Microbial plankton form the productive base of both marine and freshwater ecosystems and
are key drivers of global biogeochemical cycles of carbon and nutrients. Plankton diversity is …

Chrysophytes and other protists in High Arctic lakes: molecular gene surveys, pigment signatures and microscopy

S Charvet, WF Vincent, C Lovejoy - Polar Biology, 2012 - Springer
Microscopic analysis of the phytoplankton and other protist communities in High Arctic lakes
has shown that they often contain taxa in the Chrysophyceae. Such studies have been …

[HTML][HTML] Mixotrophy in chlorophytes and haptophytes—effect of irradiance, macronutrient, micronutrient and vitamin limitation

R Anderson, S Charvet, PJ Hansen - Frontiers in microbiology, 2018 - frontiersin.org
Chlorophytes and haptophytes are key contributors to global phytoplankton biomass and
productivity. Mixotrophic bacterivory has been detected for both groups, but a shortage of …

[HTML][HTML] Pyrosequencing analysis of the protist communities in a High Arctic meromictic lake: DNA preservation and change

S Charvet, WF Vincent, A Comeau… - Frontiers in …, 2012 - frontiersin.org
High Arctic meromictic lakes are extreme environments characterized by cold temperatures,
low nutrient inputs from their polar desert catchments and prolonged periods of low …

Effects of light and prey availability on Arctic freshwater protist communities examined by high-throughput DNA and RNA sequencing

S Charvet, WF Vincent, C Lovejoy - FEMS Microbiology Ecology, 2014 - academic.oup.com
Protists in high-latitude lakes are constrained by cold temperatures, low inorganic nutrient
supply and low light availability for much of the year due to ice cover and polar darkness. The …

Experimental identification and in silico prediction of bacterivory in green algae

NA Bock, S Charvet, J Burns, Y Gyaltshen… - The ISME …, 2021 - academic.oup.com
While algal phago-mixotrophs play a major role in aquatic microbial food webs, their
diversity remains poorly understood. Recent studies have indicated several species of …

[HTML][HTML] Prevalence of partnerships between bacteria and ciliates in oxygen-depleted marine water columns

WD Orsi, S Charvet, P Vdacny, JM Bernhard… - Frontiers in …, 2012 - frontiersin.org
Symbioses between Bacteria, Archaea, and Eukarya in deep-sea marine environments
represent a means for eukaryotes to exploit otherwise inhospitable habitats. Such symbioses are …

…, B Steven, S Charvet… - … of systematic and …, 2009 - microbiologyresearch.org
A novel, moderately halophilic, endospore-forming bacterial strain, designated Hal 1 T , was
isolated from a permafrost core collected from the Canadian high Arctic. The temperature for …

[HTML][HTML] Small pigmented eukaryote assemblages of the western tropical North Atlantic around the Amazon River plume during spring discharge

S Charvet, E Kim, A Subramaniam, J Montoya… - Scientific reports, 2021 - nature.com
Small pigmented eukaryotes (⩽ 5 µm) are an important, but overlooked component of global
marine phytoplankton. The Amazon River plume delivers nutrients into the oligotrophic …

[HTML][HTML] Late winter under ice pelagic microbial communities in the high Arctic Ocean and the impact of short-term exposure to elevated CO2 levels

A Monier, HS Findlay, S Charvet… - Frontiers in Microbiology, 2014 - frontiersin.org
Polar Oceans are natural CO 2 sinks because of the enhanced solubility of CO 2 in cold water.
The Arctic Ocean is at additional risk of accelerated ocean acidification (OA) because of …
