Observations on the behaviour of the Rufous Hare-wallaby Lagorchestes hirsutus were obtained from a captive colony maintained in Alice Springs. This information was used to interpret observations of animals made during field studies in the Tanami Desert. Aspects of the species' behavioural repertoire which were recorded included activity patterns, postures, gaits, interactions, nesting habits and vocalisations. Lagorchestes hirsutus is predominantly nocturnal and its activity patterns and body postures resemble those recorded for other species of small macropods. It appears to be a relatively solitary animal but there was some evidence of social organisation within animals maintained in captivity. Aspects of the sexual and aggressive behaviour of L. hirsutus appear to resemble more closely those of the potoroids than of larger macropodids.

AbstractThe agonistic and sexual behaviour of the Cyprinodont fish Aphyoseznion bivittatum is described. Both males and females develop colour patterns which are useful in identifying the motivational state of the fish and these are also described. Aggressive encounters between males are prolonged and highly ritualised. They result in dominant - subordinate relationships being set up and this is probably associated with a hierarchical structure of social organisation in the wild. The data was analysed to show differences in the sequences of aggressive behaviour of dominant and subordinate males. The possible adaptive values of the differences found are discussed. The sequence of courtship behaviour is relatively simple due to the limited behavioural repertoire of females.

Hydromys Chrysogaster

The Water Rat Hydromys chrysogaster is Australia's largest amphibious rodent, occupying freshwater rivers, lakes, and coastal and estuarine habitats throughout the continent (Watts and Aslin 1981). Little is known of the species' social organisation or use of space in the wild although Harris (1978) suggested that adults might be intrasexually aggressive. The home ranges of all sex and age classes overlap to some extent but home ranges of adults of the same sex appear to overlap less (Harris 1978). Adult males occupy the largest home ranges which overlap those of one or more females. In captivity individuals kept in groups form hierarchies in which only the dominant females usually breed successfully (Olsen 1982). Fighting occurs primarily among males, with the highest incidence of injuries observed at the beginning of the main September-March breeding season (Olsen 1980, 1982). The results of trapping studies indicate that population density may vary considerably, with the greatest numbers of animals typically occupying man-modified habitats such as irrigation channels or fish farms (McNally 1960, Watts and Aslin 1981, Smales 1984). Aggressive behaviour appears to be related to pelage colour (phenotype) and population density; the higher the density the greater the number of injured individuals (Olsen 1980).

The Times

The temporal activity patterns of individually housed captive southern brown bandicoots (Isoodon obesulus) were recorded using time-lapse infra-red videorecording. Recordings were made over a period of four continuous days per animal under natural lighting and climatic conditions for Perth, Western Australia during March 2002. Analysis showed that all bandicoots were almost entirely nocturnal and spent ~71% (~17 hr day-1) of their time in their nests. The times of onset of activity were remarkably regular, and occurred both following feeding during the late afternoon and again after dusk (average 1841 hrs). Bandicoots were active for an average of ~7 hr night-1. Virtually all activity involved the bandicoots running around their enclosures (~6.5 hr day-1). This running was interspersed with shorter periods spent feeding (~25 min day-1), grooming (~8 min day-1) and drinking (~2 min day-1). No other behaviours were observed. There was a greater degree of variation in the time of cessation of activity between individuals. Time of cessation ranged from 0039 hrs ± 20 min to 0504 hrs ± 25 min. The average time of cessation of activity was 0315 hrs ± 61 min and was not related to either time of onset of activity or sunrise.

Time Spent Feeding

Stereotypy is a characteristic occasionally observed in captive animals. This behaviour is regularly associated with animal housing conditions that deviate fundamentally from the species' natural environment. In addition to the detrimental affect it may have on the associated animal, it creates a difficult situation for the public in understanding the presentation of animals in captivity. In April 1996, modification to the platypus exhibit at Healesville Sanctuary resulted in an increased level of light being deflected onto the glass of the shallow tank exhibit. This change in the housing conditions coincided with repetitive circling behaviour by the female platypus and avoidance activity by the male platypus. In addition, the proportion of time spent feeding by the female platypus was reduced. Modification of the exhibit furniture did not significantly alter the female's behaviour. A reduction in the light level being deflected onto the tank resulted in an immediate reduction in the circling behaviour observed for the female. The male resumed free swimming and utilisation of the entire tank. Within two weeks all stereotypic behaviour had ceased and the two platypuses had resumed normal activity patterns.

'In a colony of captive koalas, all aggressive behaviour was a variation on the single motor pattern of throwing a foreleg around an opponent and biting. Squabbles (the most common aggressive behaviour) were brief, low level interactions usually arising from the efforts of one koala to climb past or over another. Minor fghts involved only single bites and the combatants stayed in the same place; major ,fights involved multiple bites and changes of position. Dependent young were seldom involved in aggression. Between males. minor fights were essentially intensified squabbles, but major fights involved wrestling and chasing; they were more likely between males unfamiliar with each other, or those already aroused by, e.g., other aggressive interactions. Females became aggressive especially during pregnancy and at the end of lactation. At such times they stood their ground and vocalized at other koalas, especially males, but attacked only if the opponent came within reach. Although the opponent usually withdrew. sometimes a male seemed provoked to attack. Males sometimes attacked females without obvious provocation. Aggression was slightly more common in than outside the breeding season. Competition for females or food, dominance hierarchies, appeasement, and the defence of young were not seen.

This study was focused on the monitoring of behaviour and complex social relationships existing among gelada (Theropithecus gelada) monkeys. The study involved a group of five males that were raised in captivity in the Zoo Zlín – Lešná. Ethological monitoring was performed by means of photographing of the group behaviour of these animals. Studied were the basic forms of social behaviour, i.e. food collection (foraging), free movement, (locomotion) observing of the neighbourhood (watching), grooming, climbing on trees, playing, aggressive behaviour (fighting), and resting. The temporary point of view, foraging was the most important time-consuming activity (55.3 ± 2.0 % of the study time); its maximum frequencies occurred in time intervals of 9 and 11 a.m. and 1 to 3 p.m.. The second place was occupied by the locomotion (15.3 ± 4.1 % of the study time) and its maximum frequencies were recorded between 9 and 11 a.m. and between 2 and 3 p.m. Grooming was the third most important activity (8.5 ± 4.8 % of the study time). The distribution of periods of rest (7.5 ± 3.1 % of the study time) was relatively uniform and its maxima were observed between 10:30 a.m. and 4 p.m. Observing of the neighbourhood and climbing on trees occupied 5.6 ± 3.3 % and 3.6 ± 3.0 % of the time, respectively and playing was the least frequent activity (2.2 ± 9.0 % of the study time), similarly as the aggressive behaviour (2.0 ± 23.0 % of the study time).

Most reptiles exhibit no parental care and aggressive behaviour towards heterospecific predators has rarely been recorded in the natural environment. Several species of the subfamily Egerniinae are amongst the most highly social of all squamate reptiles, exhibiting stable social aggregations and high levels of long-term social and genetic monogamy. We have examined Cunningham’s skinks, Egernia cunninghami, over a three-year period during late January and early February (total 32 days) in the alpine region of New South Wales using video and thermal imaging. Four birthing sessions were witnessed during our field studies of social aggregations of skinks. Our observations monitored skink encounters, in the presence of offspring, with an eastern brown snake, Pseudonaja textilis (two separate encounters, one recorded by video/imaging) and 12 encounters with the Australian magpie, Gymnorhina tibicen. All events were associated with aggressive chasing and/or attack by adult skinks. The first snake encounter involved the active targeting of a recently born juvenile with the mother of the juvenile attacking the snake (running towards the snake, biting and remaining attached for several seconds). The second encounter (the following year) comprised two adult skinks attacking and biting a snake, Pseudonaja textilis. All magpie encounters resulted in chases by adult skinks.
