From temperate to polar waters: Transition to non‐cyanobacterial diazotrophy upon entering the Atlantic gateway of the Arctic Ocean

Limnology and Oceanography, Volume 70, Issue 10, Page 2924-2940, October 2025.
Abstract Nitrogen fixation, the microbial reduction of dinitrogen to ammonia, is increasingly recognized to occur in the Arctic Ocean. However, knowledge about the composition, biogeography, abundance, and ecology of nitrogen‐fixing organisms (diazotrophs) is poor.

Environmental controls of autotrophic biofilm biomass and community composition in subarctic lakes and streams in Greenland

Limnology and Oceanography, Volume 70, Issue 10, Page 2941-2956, October 2025.
Abstract Photosynthetic biofilms are key components of Arctic freshwater ecosystems, supporting primary production and forming the base of aquatic food webs. While several environmental factors regulating biofilms are known, their relative importance and connection to catchment characteristics across different Arctic ecosystems remain unclear.

Rare occurrence of nine Microcystis species (Chroococcales, Cyanobacteria) in a single lake (Lake Dojran, fYR Macedonia)

Advances in Oceanography and Limnology, 2017
Investigations carried out on Lake Dojran, fYR Macedonia, during the spring-autumn seasons in 2015 have been focused on detecting the degree of eutrophication in the lake, successive algal flora changes in the plankton communities and eventual presence ...

Draft Genome Sequence of the Toxic Freshwater Microcystis aeruginosa Strain PMC 728.11 (Cyanobacteria, Chroococcales)

Microbiology Resource Announcements, 2020
Microcystis aeruginosa is one of the major species that causes toxic cyanobacterial blooms in freshwater systems worldwide. Here, we report the draft genome sequence of M. aeruginosa PMC 728.11, a microcystin-producing cyanobacteria isolated from the freshwater reservoir of Juanon in Valence, France.

Positional 13C enrichment analysis of aspartate determines PEPC activity in vivo

New Phytologist, Volume 248, Issue 1, Page 401-414, October 2025.
Summary Photoautotrophic organisms fix inorganic carbon (Ci) by RIBULOSE‐1,5‐BISPHOSPHATE CARBOXYLASE/OXYGENASE (RUBISCO) and PHOSPHOENOLPYRUVATE CARBOXYLASE (PEPC). Monitoring Ci assimilation rates in vivo is a major challenge in analyzing photoautotrophic metabolism and engineering improved photosynthesis, as conventional methods do not distinguish ...

Cyanobacteria Phylogenetic Studies Reveal Evidence for Polyphyletic Genera from Thermal and Freshwater Habitats

Diversity, 2020
Cyanobacteria are among the most diverse morphological microorganisms that inhabit a great variety of habitats. Their presence in the Azores, a volcanic archipelago of nine islands in the middle of the North Atlantic Ocean, has already been reported ...
