To investigate the functional significance of the behaviour of large mammals in hot, arid conditions, field observations were made of the behaviour of red kangaroos. The behaviour of individual animals was recorded in detail during hot summer days and measurements of the prevailing temperature and radiation environment were made. Changes in the postures adopted by animals during the day are described in relation to environmental conditions; and the occurrence of certain postures and behaviours at periods of greatest heat stress is reported.

Sexual behaviour following castration was studied in rabbits with varying precastrational sexual experience. Although most aspects of sexual behaviour declined within a few weeks of castration, experienced animals of mixed strains continued to mount with unreduced frequency for at least 10 weeks following castration. Inexperienced animals, as well as experienced New Zealand White animals, ceased to ejaculate and mount within 4 weeks. The effect of experience on postcastrational sexual behaviour thus seems to vary between different rabbit strains.

Lemur fulvus, L. catta, and L. variegatus differ markedly in the details of mother-infant relations. Do these differences account for those seen in adult life? We hope to determine this through interspecific cross-fostering. Here we describe the normal pattern of rearing of 5 infants among two groups of 2 and 5 adult L. variegatus, reared in the laboratory. The descriptions cover the first 7 months of life, and include the effects of maternal separation at 150 days of age, when estrus normally disrupts maternal care. The principal finding is that in the mother's absence young turn more to other adults than to their siblings, who are, apparently, not adequate social substitutes for adults.

The Mediterranean blenny Blennius rouxi has been studied mainly in the Banyuls-sur-Mer region. Data on its behaviour have been obtained by skin diving, SCUBA diving and observations in captivity. At Banyuls-sur-Mer Blennius rouxi lives at a depth of 1 to 42m. As an exception among Mediterranean blennies, Bl. rouxi feeds by grazing off the substrate. Algae, sponges and polychaetes (Sedentaria) are the main components of its food (HEYMER and ZANDER, in press). We could not confirm that the colouration, a white body with a conspicuous dark horizontal band, can be regarded as a signal of cleaning activity in statu nascendi. The male male have a spatial territory in which they occupy haptic holes. The female female lead a vagabond life and actively join the male male in their territories during the breeding season. Head nodding is an agonistic behaviour against other female female and has an attractive significance for spawning-motivated female female. The male male threaten with a widely opened mouth (threat yawning). Our data and observations on the ethology of Bl. rouxi are discussed and compared with those known of Bl. sphinx, Bl. incognitus, and Bl. zvonimiri, its nearest relatives.

Chemocommunication functions are known in many social mammals, such as gerbils, hamsters, and deer. But also mammals known as at least partly solitary do communicate by chemical signals. The existence and use of pheromones in domestic cats was the subject of this study. It turned out that male and female cats spent much time in exploring their own and foreigners' urine and skin gland secretion rubbed off on several objects. Male receivers performed sniffing and flehmen more frequently than females on the same urine, whereas female cats paid more attention to skin gland secretion. Both urine and cheek gland secretion of the female donor appeared to contain pheromones which inform the tomcat about her hormonal phase.

The responses of a captive family group of 12 Dwarf Mongooses (4 female and 8 male) towards a sick group member were recorded daily for 3 h over a 38 day period (until the animal died), these data being compared with those for a comparable control period. Changes in feeding rank order, resting site, resting duration and grooming frequency and duration were found, these being to the advantage of the sick individual. The probable adaptive significance of such behaviour is discussed.

The main question of our investigation is: Do there exist age-specific learning abilities in animals? 120 QUAILS (Coturnix coturnix japonica) of 12 different age groups (between one day and 20 weeks) were tested in a combination apparatus 0y using two training methods. 60 quails were trained with decreasing (1), 60 other quails with increasing learning assistance (2). In each case the learning period lasted 5 days after which the animals were tested in a two-way choice apparatus and in a simple maze. Retention was tested 3 weeks later. - The 2 methods led to different results. In general the younger animals learnt better than the other ones when trained by method 1. No differences in learning performance between the 12 age groups were obtained by method 2.

Feeding, mating behaviour, communication, breeding biology, and development of Pipa carvalhoi are described. Like in other species of the genus Pipa, the eggs are laid onto the female's back during several turnovers, and this behaviour can be observed even in the absence of males. Acoustic communication involves a mating call and a combat call. The biology and behaviour of Pipa carvalhoi are compared to that of other pipid frogs, and it is suggested that the specialized breeding biology of the genus Pipa evolved as an adaptation to the life in small ponds and ditches which are rich in nutrients but poor in oxygen.
