    Primates have an extended juvenile period associated with critical social and environmental learning. In particular, social play is positively associated with brain size in primates, indicating an important role in cognition and development. However, this behaviour has been overlooked in the Hylobatidae family. The activity patterns of eight non-adult Bornean white-bearded gibbons (Hylobates albibarbis) from four groups were studied in the Sebangau peat-swamp forest in Borneo from 2005 to 2019. We compare our findings to previous reports for adult conspecifics, report the directionality of non-adult play behaviour, and examine whether the weather impacts daily activity patterns. Feeding (39.5%), resting (27.6%) and travelling (23%) were the main activities of juveniles, while infants mostly played (42.1%) or clung to their mothers (38.3%). Non-adult groups socialised and observed their surroundings more often, and they travelled and called less often than adults. Feeding and resting frequency did not differ significantly from that of adults. Infants engaged in self-centred play twice as often as juveniles and directed most of their playing attention towards sub-adults (58%). Weather variables, previously reported to be good predictors of certain adult activities, such as singing, did not appear to affect infant and juvenile activities. Play is a critical part of primate physical and social development, and this study describes some key behaviours of young gibbons. Understanding the play behaviour of gibbons in the wild will help inform the rehabilitation of an ever-increasing number of orphaned individuals who are victims of the illegal pet trade.

    Territorios de agua: infraestructura agrícola, reforma agraria y palma de aceite en el municipio de Marialabaja (Bolívar)
    (Colombian Institute of Anthropology and History, 2018) Catalina Quiroga; Diana Vallejo Bernal
    Las dinámicas de despojo y acaparamiento de agua son un eje central en investigaciones recientes que reconocen las relaciones asimétricas de poder y el poder de la naturaleza misma en el manejo, uso y control de los recursos. Sin embargo, no son muchos los trabajos sobre las alternativas de gestión local del agua. Este artículo aporta a este conjunto de literatura a partir de un acercamiento etnográfico al distrito de riego de Marialabaja (Bolívar), en el Caribe colombiano. El análisis de la construcción de esta obra ayuda a entender cómo la infraestructura se apropia como parte del territorio, a la vez que genera relaciones desiguales de acceso al agua. También muestra las consecuencias directas de una política de desarrollo rural en las vidas cotidianas de las poblaciones locales.
