The ova of the common brown seaweeds Fucus spp.) release into sea water small amounts of w-hexane which attracts motile spermatozoa and so favours fertilization (Hlubucek et al., 1970). Hexane is active at a dilution of 1 part in 10 million and exemplifies the principle that, no matter how commonplace a chemical may be, as soon as it gives an advantageous signal in a biological system, its specificity as a messenger can be perpetuated by natural selection.

Below the Fucus-beXt, red algae, mainly perennial as Furcellaria lumbricalis, Coccotylus truncatus and Phyllophora spp. dominate, accompanied by several filamentous (e.g., Ceramium spp., Polysiphonia spp.) and crust-forming (e.g., Hildenbrandtia spp.) algae (Wallentinus, 1991). 

Lotze et al. (2001) showed that Fucus germlings in contrast to germlings of ephemeral algae Pilayella spp.) are not profiting from increased nutrient concentrations. This results, as shown by Worm et al. (2001) in Fucus being overgrown by epiphytes even if nutrient addition was given only for very short periods. 

The single and double methylations involve one and two molecules of 5-adenosylmethionine, respectively, and were first demonstrated in higher plants mPisum sativum (Castle et al., 1963), Salvia officinalis (Nicholas and Moriarty, 1963), and Menyanthes trifoliata, (Bader et al., 1964) and in the algae Laminaria saccharina (Villanueva et al., 1964), Fucus spiralis (Goad and Goodwin, 1%9), and Ochromonas spp. (Smith et al., 1966 Lederer, 1969). The mechanism proposed by Nes (Castle et al., 1963) for Cgg sterols (pathway 1, Fig. 3) and for C29 sterols (pathway 2, Fig. 3) was shown to operate in Ochromonas spp. from the following experiments ...
