 Title    Monochiralities Caused by Sexuality  
 Abstract    It is shown how the interaction of sexuality and chirality causes monochiralities of the biosphere. In [1], Rikken and Raupach say: "We show experimen-tally that magnetochiral anisotropy can give rise to an enan-tiomeric excess in a photochemical reaction driven by unpolarized light in a parallel magnetic field, which sug-gests that this effect may have played a role in the origin of the homochirality of life."* Also the fact that outside the tropics the sun goes always to the right (left) on the northern (southern) hemisphere suggests that this effect may, via the sun-dependent growth of organisms, have played a role in the origin of the homochirality of life.

 Title    Sexual Pheromones and Related Egg Secretions in Laminariales (Phaeophyta)  
 Abstract    Volatile egg secretions of 15 species belonging to 5 families of the brown algal order Laminariales have been analyzed by high resolution glass capillary gas chrom atography. 16 com­ ponents have been identified and partially determ ined quantitatively. The composition of the pherom one bouquets and pherom one specificity for induction of spermatozoid-release and -chemotaxis are discussed in respect to ecophysiological functions and significance as chemo-taxonom ic markers.
