Immature Male Chimpanzees’ (Pan troglodytes schweinfurthii) Social Relationships with Adult Males, but Not Peers, Persist into Adulthood
The cost of deep sleep
OBJECTIVES: Primates spend almost half their lives asleep, yet we know little about how evolution has shaped variation in the duration or intensity of sleep (i.e., sleep regulation) across primate species. Our objective was to test hypotheses related to how sleeping site security influences sleep intensity in different lemur species. METHODS: We used actigraphy and infrared videography to generate sleep measures in 100 individuals (males = 51, fe…
The development of feeding behavior in wild chimpanzees ( Pan troglodytes schweinfurthii )
OBJECTIVES: Primates have an extended period of juvenility before adulthood. Although dietary complexity plays a prominent role in hypotheses regarding the evolution of extended juvenility, the development of feeding behavior is still poorly understood. Indeed, few studies have investigated the timing and nature of feeding transitions in apes, including chimpanzees. We describe general patterns of feeding development in wild chimpanzees and evalu…
Activity patterns in seven captive lemur species
Cathemerality, or activity throughout the 24-hr cycle, is rare in primates yet relatively common among lemurs. However, the diverse ecological conditions under which cathemerality is expressed complicates attempts to identify species-typical behavior. For example, Lemur catta and Varecia have historically been described as diurnal, yet recent studies suggest that they might exhibit cathemeral behavior under some conditions. To investigate this va…

Transparency, usability, and reproducibility
Recent decades have seen rapid development of new analytical methods to investigate patterns of interspecific variation. Yet these cutting‐edge statistical analyses often rely on data of questionable origin, varying accuracy, and weak comparability, which seem to have reduced the reproducibility of studies. It is time to improve the transparency of comparative data while also making these improved data more widely available. We, the authors, met …
Goal negotiation with older people in three day care settings
Drawing on a wider study of effectiveness in three models of day care, this paper explores the process and outcome of goal negotiation with older people in a day hospital, an outreach service and a day centre. Using qualitative data from interviews with day care attenders and focus groups with service providers, differing perspectives on goal setting and achievement are presented. It concludes with a brief discussion of this approach in the wider…
Standardized health check data from community-dwelling elderly people
The main aim of this study was to compare EASY-Care data obtained during nurse-administered annual health checks in two populations of older people. A secondary aim was to determine whether a standardized assessment system administered as part of routine practice by a trained nurse during the over-75 health check could generate useful information for comparing population health and functional status of community-dwelling-older people. One hundred…
