Inositol and choline were present in varying amounts among the species of Rhodophyta, Phaeophyta, Chlorophyta, and Euglenophyta examined. However, in the two members of the order Fucales (division Phaeophyta) examined, no detectable amounts of choline were found. In contrast, the species of Cyanophyta examined contained no detectable amounts of either choline or inositol. All species of the fun...

137Cs activity concentrations were determined in samples of macrophytes Polysiphonia fucoides (red algae) and Zostera marina (vascular plant) collected during the entire vegetation season in the Gulf of Gdańsk in the southern Baltic Sea. The measurements showed considerable seasonality of 137Cs activity in both species; an increase of cesium concentrations was observed from spring to autumn wit...

Photosynthesis, Assimilates, C-Metabolism, M arine/Freshw ater Algae, Taxonomy The representatives of the major algal divisions including Chlorophyta, Rhodophyta and Heterokontophyta usually show specific patterns o f accumulated photoassim ilatory products. Among these compounds, the accumulated low-molecular weight carbohydrates such as mono­ saccharides, disaccharides, alditols (i.e. polyhyd...

Understanding critical habitats of threatened and endemic animals is essential for mitigating extinction risks, developing recovery plans, and siting reserves, but assessment methods are generally lacking. We evaluated critical habitats of 8 threatened or endemic fish species on coral and rocky reefs of subtropical eastern Australia, by measuring physical and substratum-type variables of habita...

Lomentaria hakodatensis Yendo, known from China, Japan, Korea, and the Pacific coasts of North America, was recorded for the first time in the lagoon of Venice on the Adriatic Sea in 2000. Specimens in the reproductive stage had tetrasporophytes, male, and female gametophytes. Morphological, anatomical, and reproductive features of the thalli are described and the occurrence of the species in t...

An extract of the red alga, Neorhodomela aculeata, exhibited antiviral activity against human rhinoviruses. Bioassay-guided purification was performed to yield six compounds, which were subsequently identified as lanosol (1) and five polybromocatechols (2-6) by spectroscopic methods, including 1D and 2D NMR and mass spectrometric analyses. Structurally, all of these compounds, except compound 5...

The name Dasya pilosa (Weber-van Bosse) A. Millar has become accepted in the current literature and is regarded as having the two heterotypic taxonomic synonyms D. adhaerens Yamada and Dasyopsis anastomosans Weber-van Bosse. The historical background of this synonomy is presented, including current ideas about the relationship between Dasya and Eupogodon. Because the oldest name available is Da...
