BACKGROUND AND AIMS Brown algae are critical components of marine ecosystems around the world. However, the genome of only one species of the class has so far been sequenced. This contrasts with numerous sequences available for model organisms such as higher plants, flies or worms. The present communication expands our coverage of DNA content information to 98 species of brown algae with a view...

First reported for the Azores in 1994, Endarachne binghamiae is commonly found throughout the year on hard substrates in the upper mid-tidal region of the exposed Azorean shores. Morphological and culture studies of this species were carried out based on material collected from six localities on the island of São Miguel. Erect thalli collected in the field are dorsiventrally flattened and arise...

On the exposed rocky shores of central Chile there exists a continuous small-scale harvesting of bull-kelp Durvillaea antarctica, by 'mariscadores' (shellfish and algae gatherers). These harvest both fronds and stipes for human consumption. To assess the effects of human activity on D. antarctica populations, the density, standing crop and size structure of the kelp were compared in nonharveste...

Mineral composition of algal biomass from Fucus vesiculosus (the Baltic Sea, Estonia) is rich in light elements (Mg, K, Ca, Na) and halogens (Br, I). Arsenic content is also high (over 300 ppm); the content of other toxic elements (Hg, Sb, Se, etc.) is extremely low. Mineralization of the algal whole biomass does not depend on seasonal varieties. The content of α-L-guluronic acid residues, and ...

This study collates compositional analysis of seaweeds data with information generated from in vitro gas production assays the presence and absence seaweeds. The aim was to assess rank 27 native northern European as potential feed ingredients for use reduce methane emissions ruminants. It provides future vivo dietary trials concerning manipulation strategies CH 4 efficiently domestic ruminants ...
