“…Inductive mechanisms involving detection of spawns of other individuals, especially those of the opposite sex of the same species, may evolve under such selective pressures (e.g. Beach et al 1975, Zeeck et al 1988, Painter 1992, Hardege et al 1996. Gametes may be released only when those of others are around.…”

Possible roles of pheromones in inducing spawning of 2 brittle stars, Ophiocoma dentata and Ophiocoma scolopendrina, were tested with gonad homogenates. In both species, the ovary homogenate induced conspecific, competent males to spawn. The potential pheromone was speciesspecific and had no effect on conspecific females. The testis homogenate did not have any effect. Of the males 50% could be induced at an estimated concentration of 7.8 × 10 -7 g ml -1 (wet ovary weight/seawater) with a threshold concentration at 10 -8 g ml -1 . Some males could be induced to spawn at least 3 consecutive times at 1 d intervals. The unidirectional induction, i.e. males induced by female releasate, suggests high selective pressure of sperm limitation in these 2 species.

“…Shared mating experience, similar or familiar reproductive behaviour, sex signaling, sensory, hormonal and tactile cues are all important pre-mating factors which influence both the rate and volume of reproductive activities in snail populations (Phelan and Baker, 1987;Zeeck et al, 1988;Frey et al, 1998;Hankison and Morris, 2003;Jang et al, 2009;Koene, 2010). Olfaction and tactile cues are known to play decisive roles in mate selection during courtship and mating in snails (Horth, 2007;Tekeichi et al, 2007).…”

Three populations of Archachatina marginata snails (P 1 , P 2 and P 3 ) obtained from natural snail habitats located in three states of Nigeria (one population per state) namely Enugu, Edo and River States were evaluated for pre-mating reproductive isolation using mate-choice tests. Total number of mated snails were very small (19.2%) compared to the number tested. Mating propensity (MP) varied significantly (P ≤ 0.05) among snail populations in two test groups and observed MP in the test groups differed significantly (chi-square test, P < < < <0.05; 0.001) from that expected under random mating. Pair formation was significantly (chi-square test, P < < < < 0.05; 0.001) influenced by differences in MP and within-population (homotypic) and between population (heterotypic) mating occurred in frequencies that differed significantly (chi-square test, P ℜ ℜ ℜ ℜ 0.05; 0.001) from that expected under random mating. Whereas observed heterotypic pair formation were less than that expected under random mating, homotypic pair formation were either equal or more than that expected under random mating. Duration of reproductive activities differed significantly (P ≤ 0.05) among test populations. It was concluded that reduced pair formation, elongated duration of courtship, and reduced mating between populations of A. marginata, indicate partial or incomplete pre-mating reproductive isolation.

“…In Platynereis dumerilii the nuptial dance is triggered by a volatile ketone, 5-methyl-3-heptanone (Zeeck et al 1988), which was extracted via a closed loop stripping technique (Grob & Zurcher 19761 and identified by means of GC-MS analysis. The nuptial dance is followed by the release of gametes of both partners due to further pheromonal signals of non-volatile character but, to date, still unknown chemical nature.…”

Sex pheromones in marine polychaetes:volatile organic substances (VOS) isolated from Arenicola marina

Volatile organic substances (VOS) were extracted from the coelomic fluid of gravid specimens of the lugworm Arenicola marina through the use of using a closed loop stripping technique and analysed via coupled gas chromatography-mass spectroscopy. VOS detectable in coelomic fluid of mature specimens include aldehydes, n-alkanes, methyl-alkanes, terpenes and ketones. The bouquet of compounds is very similar to nereid volatiles that have been recently described as having sex pheromonal activity. One of the major constituents is the ketone 5-methyl-3-heptanone, the sex pheromone of Platynereis dumerilii and Nereis succinea. Behavioural bioassays with gravld specimens produced no evidence that this substance has any pheromonal function in A. marina. Samples taken at monthly intervals showed an increase in the content of VOS in the coelomic fluid of both sexes during maturation with 1 major peak, 2-ethyl-hexanol, representing up to 50% of the total amount of VOS in spawning male lugworms. Behavioural assays with ripe females established the existence of a chemical cue inducing the burrow ~rngation behaviour during which sea water is pumped through the burrows. This behaviour ensures transport of spermatozoa from the water column into the tube inhabited by the female and increases fertilization success by minimising the dilution effects of the incoming tide. The VOS extract obtained from male spawning water had biological activity in eliciting the 'pumping' behaviour in females, with 16 of 24 worms irrigating continuously upon exposure, whilst controls showed no increase of activity, with 'pumping' occurring at 30 to 40 min intervals.
