The joy of sex pheromones.
Sex pheromones provide an important means of communication to unite individuals for successful reproduction. Although sex pheromones are highly diverse across animals, these signals fulfil common fundamental roles in enabling identification of a mating partner of the opposite sex, the appropriate species and of optimal fecundity. In this review, we synthesize both classic and recent investigati...
متن کاملNovel Sex Cells and Evidence for Sex Pheromones in Diatoms
BACKGROUND Diatoms belong to the stramenopiles, one of the largest groups of eukaryotes, which are primarily characterized by a presence of an anterior flagellum with tubular mastigonemes and usually a second, smooth flagellum. Based on cell wall morphology, diatoms have historically been divided into centrics and pennates, of which only the former have flagella and only on the sperm. Molecular...
متن کاملSex pheromones in amphibians: a review
Amphibians are interesting animals, very often kept by aquarists and vivarists. Their ability of intraspecific chemical signalization belongs to very interesting biological features. The skin glands of anurans secrete various biologically active compounds. The pheromones are peptides consisting of various numbers of amino acid residues and their synthesis is regulated by hormones (e.g. prolacti...
متن کاملSex and the single neuron: pheromones excite.
Pheromones are potent chemical signals used by animals across all phyla to control reproductive function and social behavior. Whereas there are few examples of the effects of pheromones on human behavior (fortunately?), in other species, such as laboratory mice, the effects of pheromones have been shown to be dramatic: a female mouse might abort a pregnancy if exposed to pheromones from a male ...
متن کاملA mutation with major effects on Drosophila melanogaster sex pheromones.
Sex pheromones are intraspecific chemical signals that are crucial for mate attraction and discrimination. In Drosophila melanogaster, the predominant hydrocarbons on the cuticle of mature female and male flies are radically different and tend to stimulate or inhibit male courtship, respectively. This sexual difference depends largely upon the number of double bonds (one in males and two in fem...
