Rhenium uptake and distribution in phaeophyceae macroalgae, Fucus vesiculosus

Rhenium uptake and distribution in phaeophyceae macroalgae, Fucus vesiculosus

Owing to Rhenium (Re) having no known biological role, it is not fully understood how Re is concentrated in oil kerogens. A commonly held assumption is that Re is incorporated into decomposing biomass under reducing conditions. However, living macroalgae also concentrate Re to several orders of magnitude greater than that of seawater. This study uses Fucus vesiculosus to assess Re uptake and it...

Frequent Clonality in Fucoids (fucus Radicans and Fucus Vesiculosus; Fucales, Phaeophyceae) in the Baltic Sea(1).

Asexual reproduction by cloning may affect the genetic structure of populations, their potential to evolve, and, among foundation species, contributions to ecosystem functions. Macroalgae of the genus Fucus are known to produce attached plants only by sexual recruitment. Recently, however, clones of attached plants recruited by asexual reproduction were observed in a few populations of Fucus ra...

Proximate Composition and Nutritional Value of Three Macroalgae: Ascophyllum nodosum, Fucus vesiculosus and Bifurcaria bifurcata

Proximate composition (moisture, protein, lipid and ash content) and nutritional value (fatty acid, amino acid and mineral profile) of three macroalgae (Ascophyllum nodosum, Fucus vesiculosus and Bifurcaria bifurcate) were studied. Chemical composition was significantly (p < 0.001) different among the three seaweeds. In this regard, the B. bifurcata presented the highest fat content (6.54% of d...

Observation of bacteria over the surface of released oogonia from Fucus vesiculosus L. (Phaeophyceae)

Pese al enorme número de bacterias que se encuentran normalmente en la columna de agua, se registra por primera vez su presencia sobre oogonios del alga Fucus vesiculosus. En cortes transversales, sin embargo, los oogonios se encontraban libres de epibiosis. Las algas fucoides son fundamentales en ciertos ambientes costeros, mas el impacto microbiano sobre su ciclo de vida y colonización es com...
