摘要:

AbstractThis paper describes in detail the elements of social behaviour and social organizations of four closely related rodents (Notomys alexis, Pseudomys albocinereus, P. shortridgeiandP. desertor) from diverse habitats, and the social organizations of seven other conilurine rodents are described briefly. Most of the data were determined from quantitative observations of animals caged in twos or in larger groups for at least ten days. Breeding pairs were observed daily throughout pregnancy and parenthood. A dispersed organization and three types of communal organization are described, and evolutionary trends in dispersion and territoriality, cohesion, communication and co‐operation are discusse

摘要:

AbstractThe possibility that displacement activities might be consequences of stress‐induced humoral responses was investigated. Adrenocorticotropic hormone and glucose were injected into the brain ventricles of unrestrained domestic pigeons. ACTH leads to an increased frequency of yawning and headshaking and glucose to a decrease in arousal. It is concluded that these behavioural responses correspond partly with the displacement activities shown by birds. The role of the cerebrospinal fluid as a mediator of behaviourally active substances is discusse

摘要:

AbstractDevelopmental changes in the frequency of occurrence of some 23 action patterns were studied in pairs of coyotes, wolves, dogs and their hybrids. Over 4,300 entries were recorded from days 24–42 (85.5 h observationsin toto). All subjects showed a decrease in contactual behaviors from 24–30 days, and a subsequent increase in play fighting and chasing. In all species, with the exception of the coyotes, the bite was inhibited and play behavior was recorded from 24 days onwards, but only after the 30th day in the coyotes. Species differences in occurrence and frequency of certain action patterns were evident in the wolves, coyotes and dogs, and these differences were also reflected in their hybr

摘要:

AbstractLemur fulvus, L. catta, andL. variegatusdiffer 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 adultL. 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 adu
