Copulatory Behaviour

While preparing a review of published descriptions of copulatory behaviour in macropod marsupials (McLean, Lundie-Smith and Jarman 1993), we were surprised to find no description for one of the most studied species, the quokka (Setonix brachyurus, e.g. see Bradshaw 1983). Copulating quokkas have been seen previously by researchers (e.g. Kitchener 1970), but no account was given. Here we provide descriptions of copulatory behaviour in quokkas, and comment on levels of sexual behaviour and activity by quokkas in the wild and in captivity.

The Arabian leopard is a critically endangered subspecies endemic to the Arabian Peninsula. A fundamental understanding of the ovarian activity of the leopard is important to enhance the success with which it breeds in captivity. The objective of the present study was to characterise the endocrinology of the follicular cycle, ovulation and pregnancy in captive females using faecal steroid hormone analyses and observations of sexual behaviour. The follicular cycle of the leopard was shown to last 18–23 days based on the interval between consecutive peaks of faecal oestrogen conjugates, and the occurrence of silent heats was high. Puberty had commenced at 2 years of age, but faecal steroid profiles did not match those of the adult female until 3 years of age. No seasonal change in ovarian steroid excretion was observed, although behavioural oestrus was suppressed in summer. Significant rises in faecal progestagen concentrations were only recorded in mated leopards, indicating that these females were strictly induced ovulators. However, only 60% of these mating periods were ovulatory. Progestagen concentrations during pregnancy were significantly higher than those of the non-pregnant luteal phase. The average duration of the non-pregnant and pregnant luteal phases was 39 and 97 days, respectively. The basic features of the reproductive cycle of the Arabian leopard described here form an important foundation for further study into its reproduction.

Behavioural Repertoire

The behavioural repertoire of Macropus rufus in captivity is described in comparison with data from literature. Most behavioural elements observed do not differ from those of free-ranging populations. Some new elements of agonistic and sexual behaviour are described. The sequential organisation of adult social behaviour allows a distinction between the functional categories of agonistic, friendly and sexual behaviour as well as a series of transitional elements. In sexual behaviour, low-intensity sexual checking can be distinguished from high-intensity courting and mating behaviour. In agonistic contexts a distinction between elements of ritualised and unritualised fighting is possible on the basis of sequences, with fixed sequences of behaviour patterns in ritualised fighting. Young M. rufus show nearly all behaviour patterns of adults, though frequently out of context. Their behavioural repertoire is not organised into different functional categories. Playfighting as well as running-play are not restricted to the mother-young dyad.

In Captivity

At the height of the breeding season male koalas frequently attempted copulation. These attempts were often apparently spontaneous, but many followed bellowing or agonistic interactions. Sexual behaviour began at 3 y old in males, except for penile erections, which sometimes occurred in younger males. Males performed no courtship behaviour. Behavioural oestrus was brief, and consisted of four distinct types of activity: jerking, bellowing, mild aggression towards the male, and pseudomale behaviour. Oestrous females could become very excited by the presence of a male, and the four activities were very flexible in their expression. Copulation itself was quite brief and consisted of mounting, thrusting, convulsions, and disengagement. The pair were always in a vertical position in a tree, the male grasping the female's neck in his jaws.

Semen Extender

The increasing number of endangered snake species, isolation of small fragmented populations with associated inbreeding and mating or conception problems in captivity underscore the need to develop assisted reproductive techniques such as semen cryopreservation and artificial insemination to enhance conservation efforts. However, no efficient protocols for semen evaluation, cooling, or freezing are described in the 4 known publications on snake semen cryopreservation. In this initial study, semen was collected noninvasively from 4 live adult red diamond rattlesnakes (Crotalus ruber) by ventral massage. An aliquot of each ejaculate was diluted in Ham's F10 and evaluated for motility and speed of progression (SOP, scale of 1–5, 5 being fastest) before and after freezing. Because ejaculate volumes were very small, each one was subjected to 2 to 4 treatments only. Samples were diluted in Lake's extender with 2 or 4% dimethyl sulfoxide or Test-Yolk extender with 4%, 8%, or 10% glycerol before cooling to 4°C. Semen extended with Lake's (a common avian semen extender) was then frozen by one of two protocols (FP): FP1, pelleted in liquid nitrogen vapor; FP2, placed in cryovials in an alcohol bath for 4 h in a –80°C freezer (cooling rate of 1°C min–1). Semen extended with Test-Yolk (a widely used mammalian semen extender) was frozen by one of two protocols: FP3, placed in cryovials in a controlled-rate freezer and cooled at 1°C min–1 to –20°C, then 50°C min–1 to –80°C; FP4, placed in cryovials in a controlled-rate freezer and cooled at 1°C min–1 to –8°C, then 3°C min–1 to –16°C, then 5°C min–1 to –80°C. Interestingly, semen frozen in Lake's extender exhibited no post-thaw motility, regardless of dimethyl sulfoxide concentration or FP (Table 1). In contrast, all semen frozen in Test-Yolk exhibited motility post-thaw. Semen from male 42 frozen by FP3 with 8% glycerol resulted in the greatest post-thaw motility of all treatments for both males. However, the same treatment for male 122 was not as successful, suggesting a possible male effect on semen cryosurvival (Table 1). The single sample frozen with 4% glycerol exhibited the lowest post-thaw motility, indicating that higher concentrations of the cryoprotectant may be beneficial to snake sperm. The exciting results of this preliminary study may guide future research in the long-neglected field of snake semen cryopreservation.
