Calcium carbonate and phosphorus interactions in inland waters

Limnology and Oceanography Letters, Volume 10, Issue 2, Page 158-178, April 2025.
Abstract Phosphorus, an element essential to all life, is impacted by calcium carbonate (CaCO3) co‐precipitation and dissolution dynamics across aquatic ecosystems. Changes to climate, hydrology, and eutrophication, coupled with differences in terminology related to naming CaCO3‐producing ecosystems (i.e., chalk, carbonate, karst, travertine), point to

Alternating Drying and Flowing Phases Control Stream Metabolism Through Short‐ and Long‐Term Effects: Insights From a River Network

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 3, March 2025.
Abstract Stream metabolism is a key biogeochemical process in river networks, synthesizing the balance between gross primary production (GPP) and ecosystem respiration (ER). Globally, more rivers and streams are drying due to climate change and water abstraction for human uses and this can alter the organic carbon residence time leading to decoupled ER

EST analysis of the scaly green flagellate Mesostigma viride (Streptophyta): Implications for the evolution of green plants (Viridiplantae)

BMC Plant Biology, 2006
Background The Viridiplantae (land plants and green algae) consist of two monophyletic lineages, the Chlorophyta and the Streptophyta. The Streptophyta include all embryophytes and a small but diverse group of freshwater algae traditionally known as the ...

Nieuwe waarnemingen van Tolypella (Charophyceae) in België

, 2019
Three Tolypella species (T. glomerata, T. intricata and T. prolifera) have been recorded in Belgium, all of them only sparingly and with most observations dating from the 19th C. We document new records of T. glomerata and T. intricata from stagnant fresh water in the Flemish region and discuss the general ecology and distribution of these rare species,

New Strains of the Deep Branching Streptophyte Streptofilum: Phylogenetic Position, Cell Biological and Ecophysiological Traits, and Description of Streptofilum arcticum sp. nov

Environmental Microbiology, Volume 27, Issue 1, January 2025.
The deep branching streptophyte algae Streptofilum is characterised by a unique cell coverage. Here, we present new strains of the genus and characterised those strains comprehensively. We found that the unique coverage is a common feature in this genus and described a new species within the genus based on morphological and molecular differences ...

Chara squamosa (Characeae, Charophyceae) in Serbia - insights from the taxonomic revision of the BEOU charophyte collection and recent field records [PDF]

Botanica Serbica
Chara gymnophylla is one of the first charophyte species reported for Serbia during the late 19th and the early 20th centuries, and at that time it was the second in terms of the frequency of its occurrence in the country.
