title: The Sperm Attractant of the Marine Brown Alga Ascophyllum nodosum (Phaeophyceae).
abstract: Spermatozoids of the intertidal seaweed Ascophyllum nodosum (Fucales, Phaeophyceae) are attracted to eggs prior to fertilization. The attractant has been isolated and its structure identified as 1(3E, 5Z, 8Z)-undecatetraene (finavarrene). The relation of finavarrene to sex hormones in other brown algae is discussed.
