摘要:

AbstractObservations in captivity of 9Ptilocercusand 12 Echinosorex are described. Behavioral data include information on predation, nesting, defense, locomotion and communication (including physical details of vocalizations). Inferences concerning early mammalian evolution are discussed.

摘要:

AbstractJewel fish possess an innate cognitive mechanism which recognizes the two facing eyes of other fish. This mechanism functions adaptively in both a social and antipredator context, estimating the risks associated with other facing fish. Appearing about the time fry begin to school, this mechanism triggers a discriminative flight response to approaching models with two schematic facing eyes. Fry also tend to avoid the region in front of the parents from which they can see their two facing eyes.In a social context, juveniles and adults appear to be intimidated by facing adversaries as demonstrated by their energy expenditure during attacks and readiness to attack, respectively. These findings are discussed in relation to developmental plasticity of the innate cognitive mechanism and concomitant changes in risk assessment.

摘要:

AbstractThe determination of hormone titers in small plasma volumes by radioimmunoassay makes it possible to demonstrate the mutual relationship between testosterone titers and sexual behaviour. Testosterone titers were measured after courtship tests in male Zebra Finches to determine whether these levels are influenced by sexual behaviour. The results show that immediately after a courtship test there is a significant difference in hormone levels between sexually experienced and inexperienced birds. Sexual experience can also be shown to influence baseline testosterone titers in male Zebra Finches: experienced ♂♂ have a high baseline level while inexperienced ♂♂ have a low baseline level. In two other behaviour patterns, undirected song and courtship song, it could be demonstrated, that the amount of these behaviours shown is linearly correlated with the amount of testosterone in the blood plasma. Both song types have different hormonal threshold values. The comparison of testosterone titers between different treatment groups can only be made if the groups are maintained under identical conditions, since housing conditions appear to have a very marked influence on testosterone titers. The mechanism of action of testosterone in sexual behaviour is di

摘要:

AbstractThis paper reports the social behavior of two groups of captiveLemur variegates.An intensive three‐month study provided baseline data. This was supplemented by two years of follow‐up observations. Various components of the captive behavioral repertoire are described. Data on feeding behavior, vocalizations, grooming, agonistic interactions, sexual behavior and infant development were collec
