Carbon and nitrogen contents depends on macroalgal species, their tissue section, and development stage

open access: yesPhycological Research, Volume 74, Issue 2, Page 175-187, April 2026.
SUMMARY Assessing the potential for macroalgae to function as a carbon sink (blue carbon) and nitrogen (N) assimilation is under intensive investigation. The content of elemental carbon (C) and N in macroalgae is the best indicator of their potential; however, with respect to the thallus, C and N content varies in space and time.

Evaluating the possible role of bottom currents and internal waves in shaping seafloor morphology in a mesophotic reef

open access: yesSedimentology, Volume 73, Issue 3, Page 593-619, April 2026.
ABSTRACT Mesophotic reefs are located in low light conditions which, depending on the region, are usually found in water depths greater than ~30 m. They are less affected by ocean warming than reefs found in shallower water depths and thus might become increasingly important for the sustainability of marine biodiversity.

Molecular phylogeny of the Family Scytosiphonaceae (Phaeophyceae)

open access: yesALGAE, 2006
Recent phylogenetic studies of scytosiphonacean brown algae show many conflicts with current classification. In order to clearly define the phylogenetic relationships of the family, we newly sequenced the photosystem I coding psaA gene (1488 base pairs) from 13 taxa (15 samples), of the family, and, for comparison, rbcL from four taxa.

Risk assessment of the production of seaweed in the Netherlands; food safety and nature

open access: yesFood Risk Assess Europe, Volume 4, Issue 2, April 2026.
Abstract Seaweed is seen as an important source of alternative proteins for a sustainable food system and food security. The cultivation of seaweed is therefore encouraged by the European Union (EU) and also by the Dutch government.In the Netherlands, seaweed is farmed on small scale in the Southwest Delta, the Wadden Sea and the North Sea. Despite the

SEASONALITY AND SPECIES COMPOSITION IN THE BENTHIC ALGAE OF CACIQUE REEF FLAT, CARIBBEAN COAST OF PANAMA

open access: yesTecnociencia, 2006
    A one year study (April 1998 to May 1999) was conducted on the Cacique reef flat in the Caribbean coast of Panama. Of 49 species of benthic macroalgae encountered, 17 (35%) were Chlorophyceae, 13 (26%) Phaeophyceae and 21 (43%) Rhodophyceae.

Diterpenes from the Brown Alga Dictyota crenulata

open access: yesMolecules, 2008
The crude extract of the Brazilian brown alga Dictyota crenulata was analyzed by NMR spectroscopy and HRGC-MS techniques. Seven diterpenes were identified: pachydictyol A, dictyodial, 4β-hydroxydictyodial A, 4β-acetoxydictyodial A, isopachydictyol ...

The complete plastid genome of the brown alga Scytosiphon lomentaria (scytosiphonaceae, phaeophyceae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
The complete plastid genome of Scytosiphon lomentaria was determined in this study. The circular genome was 139,208 bp in length with the GC content of 31.3%. It contained 137 protein-coding genes (PCGs), 27 transfer RNA (tRNA) genes, and 8 ribosome RNA (

Antiprotozoal Activities of Organic Extracts from French Marine Seaweeds

open access: yesMarine Drugs, 2011
Marine macrophytes contain a variety of biologically active compounds, some reported to have antiprotozoal activity in vitro. As a part of a screening program to search for new natural antiprotozoals, we screened hydroalcoholic and ethyl acetate extracts
