Effect of light on the circadian activity rhythm of the slow loris, Nycticebus coucang
… study, the locomotor activity of a nocturnal prosimian, the slow loris (<em>Nycticebus coucang</em>), was monitored under an experimentally varied light regime. During the process of reversing their day-night cycle, activity was monitored for a light-dark cycle roughly correlating to the …

Captive breeding programmes for nocturnal prosimians
… the nocturnal and arboreal nature of nocturnal prosimians field research on these species is limited. Maintaining populations in zoos provides an opportunity to increase our knowledge of these elusive species. This study aimed to update and contribute to the limited research on captive …

Neuroethology of Social Attention in Primates
… novel telemetric device in socially-interacting prosimian primates, and later in monkeys and humans responding to gaze cues in the lab. Finally, we examined the neuronal responses to gaze cues in a macaque posterior parietal area implicated in attention control--the lateral intraparietal area, …

Behavior and Ecology of Wild Slow Lorises (Nycticebus coucang): Social Organization, Infant Care System, and Diet
… loris Nycticebus coucang, a nocturnal arboreal prosimian primate, in the Malaysian rainforest. Data collected are locational data obtained during 1,000 h of radio-tracking slow lorises, behavioral data from visually observing radio-collared individuals, morphometric data, and records on food …

An Assessment of Number Representation in the Small-Eared Bushbaby (<i>Otolemur garnettii</i>)
<p>In an effort to explain the underlying mechanisms of number representation, both the object-file and the approximate number system have been proposed. Despite the recognition in animals, both nonhuman and human, it remains unclear how numbers are represented cognitively or what system is …
