AbstractObservations of a free-living population of Bosca's newt, Triturus boscai, show that courtship behaviour in nature is similar to the behaviour observed in earlier laboratory studies. Complementary evidence was obtained on the behaviour called flick, which is sometimes inserted at the end of the static display phase, and may be viewed as an equivalent behaviour to the retreat display of the other small-bodied newt species. Sexual interference in the natural population was mainly caused by males. Two characteristic male behaviour patterns were recognised, the waiting position and the push-tail. Females tend to withdraw from situations of interference. Courtship sequences solely consisting of orientation and spermatophore transfer phases, so-called short-circuit sequences, may be interpreted as a male strategy to avoid the very severe male-to-male interference that exists in a wild population.

Due to low population densities, copulation in the cuckoo bee genus Nomada has not previously been observed, although a seminal paper by Tengö and Bergström (1977) on the chemomimesis between these parasitic bees and their Andrena or Melitta hosts postulated that secretions from male glands might be sprayed onto females during copulation. Our observations on the initiation and insertion phase of copulation in three species of Nomada now indicate antennal grabbing as a mechanism by which chemicals are transferred between the sexes. Histological studies of the antennae of N.fucata and N.lathburiana reveal antennal modifications associated with cell aggregations that represent glandular cells, and SEM studies revealed numerous excretory canals.

SUMMARY To determine whether the display of male courtship behaviour depends on the action of androgen on discrete areas of the brain, single crystalline implants of testosterone propionate (TP) (mean weight 40 μg) were positioned unilaterally in the brains of castrated male Barbary doves. Implants in the preoptic, anterior hypothalamic and lateral hypothalamic areas induced the full courtship display consisting of chasing, bowing and nestsoliciting. None of these behaviour patterns was re-established at precastration levels measured in terms of duration of display. Durations of courtship displayed by implanted males were similar to those induced by daily intramuscular injections of TP (300 μg/day × 15) into castrated birds. The effectiveness of implants of TP into other regions of the brain could be related to their proximity to the preoptic and anterior hypothalamic regions. There were marked deficits in the pattern of courtship of castrated doves with implants in areas adjacent to the preoptic and anterior hypothalamic regions — the neostriatum intermediale, the area basalis, and posterior hypothalamus; implants more distantly placed in the paleostriatum primitivum and lateral forebrain bundle area did not induce courtship behaviour. Cholesterol implants (59 μg) and blank implant tubing in the preoptic and anterior hypothalamic areas did not affect behaviour. The results obtained were not specific for TP implants; chasing and nest-soliciting displays were also induced by either testosterone implants (51 μg) or oestradiol-17β monobenzoate implants (47 μg). In both cases, the courtship display lacked bowing. It is concluded that the preoptic and anterior hypothalamic areas are directly sensitive to testosterone and that these areas are associated with the control of courtship behaviour.

Social Association

Abstract Although male courtship displays have evolved primarily to sexually attract females, they also generate inadvertent public information that potentially reveals the courter’s relative sexual attractiveness and the perceived quality and sexual receptivity of the female being courted to nearby eavesdropping male competitors, who in turn may use this information to bias their social partner choices. We tested this hypothesis by first presenting individual eavesdropping male guppies (Poecilia reticulata) the opportunity to simultaneously observe two demonstrator males whose courtship behaviour was manipulated experimentally to differ, following which we tested them for their preference to associate socially with either demonstrator males. Test males preferentially associated with the demonstrator male who they had previously observed courting a female over the other (non-courting) demonstrator. This social association preference was not expressed in the absence of a female to court. Our findings highlight the potential for sexual behaviour influencing male-male social associations in nature.

Courtship Displays

Gobies emit sounds during different stages of reproduction, including courtship, pre-spawning events (in the nest) and spawning. The breeding sounds of the painted goby Pomatoschistus pictus and associated courtship behaviour were recorded in captivity and described for the first time. Males emitted thump-like sounds mainly when displaying alone in the nest and produced drumming sounds outside the nest. Thumps have never been reported for other species of the genus Pomatoschistus. Thumps were short (~80 ms) very-low frequency (below 100 Hz) non-pulsed sounds, whereas drums were longer (hundreds of ms) and consisted of low frequency (~300 Hz) pulse trains. Thump characteristics varied significantly among males but also showed high within-male variability. The frequency of thump emissions and courtship behaviour (total number of courtship displays, lead and nest display) were positively correlated with male size but not with male somatic condition. Thump bursts emitted during nest displays were significantly longer than when emitted with other behaviours. These results suggest that larger males courted females more intensively, both with visual and acoustic displays, than smaller ones.

Norwegian Fjord

The distribution pattern and nocturnal surface behaviour of the deep-sea medusa Periphylla periphylla in a Norwegian fjord was studied. Medusa abundance, size distribution and condition were determined, using surface collections, net tows and ROV-based video profiles. Only larger, mature medusae reached the surface and aggregated into small groups of both sexes, whereas juvenile medusae remained in deeper waters. Observations on the behaviour and cytology of aggregated medusae suggested a mating strategy. We hypothesize that this behaviour is the by-product of a holopelagic life history, developed in a more oceanic deep environment with low species abundance, as surface aggregation increases the chance of encounter and mating.
