Effect of solar eclipse on the behavior of a captive group of hamadryas baboons (Papio hamadryas)

Abstract 10.1002/zoo.10077.abs To date there have been no systematic studies on the effects of a solar eclipse on the behavior of nonhuman primates. However, some descriptive studies have reported an increase in inactivity levels and congregation of individuals during a solar eclipse. The aim of the present work was to carry out a systematic study […]

Relationship between feeding time and food intake in hamadryas baboons (Papio hamadryas) and the value of feeding time as predictor of food intake

Abstract 10.1002/(SICI)1098-2361(1999)18:63.3.CO;2-L The relationship among time spent feeding, number of feeding bouts, feeding bout length, and the amount of food ingested was determined in a study of 18 hamadryas baboons (Papio hamadryas) at the German Primate Center (DPZ). There was considerable within- and between-subject variation in all four variables. Feeding time and number of feeding […]

Application of Piecewise Hierarchical Linear Growth Modeling to the Study of Continuity in Behavioral Development of Baboons (Papio hamadryas)

In behavioral science, developmental discontinuities are thought to arise when the association between an outcome measure and the underlying process changes over time. Sudden changes in behavior across time are often taken to indicate that a reorganization in the outcome-process relationship may have occurred. The authors proposed in this article the use of piecewise hierarchical […]

Social bonds in female baboons: the interaction between personality, kinship and rank

Previous analyses indicate that female baboons that form strong and stable social bonds reproduce more successfully than others, and that some elements of females’ personalities are associated with the tendency to form close social bonds. Here we use a new method to confirm that females’ personalities were stable over time, although not fixed, and that […]
