On a carbon dioxide gradient in the Fucales egg
1954Previous investigations suggest that a CO2-pH gradient is involved in the development of polarity in the Fucales egg. To test this hypothesis, a method was developed to measure the relative CO2 output from the two hemispheres of this egg. The eggs are photosynthetically tagged with C14 and embedded in a thin jelly membrane in which the eggs develop ...

During the 43 days natural and laboratory experiments it was established that in Ascophyllum nodosum (L.) Le Jol. Fucus vesiculosus L. and F. serratus L. from the Barents Sea the changes in the pigments concentrations take place after polar night. The data obtained are discussed, while taking into account the adaptation of photosynthetic apparatus of ...

Seasonal module dynamics in Sargassum subrepandum (Fucales, Phaeophyta)
Journal of Phycology, 2008Module dynamics of the fucoid alga Sargassum subrepandum (Forssk.) C. Agardh was studied in the southern Red Sea. Seasonal variation in thallus density and size was determined, and the initiation, growth, reproduction, and shedding of modules (primary laterals) were ascertained, using a tagging approach.
