Some chimpanzee populations exhibit ground night nesting, which occurs in different habitat types, is driven by a variety of interconnected factors, and may reflect cultural or social differences. This has important implications for ape conservation management, given that accurate nest builder identification is required to estimate density, crucial in(More)
We examined 834 nests built by western lowland gorillas in Cameroon between July 2008 and July 2011 to identify the plant species used in their construction. Preference for each plant species for nesting was assessed using a ‘preference index’ calculated by combining information on the occurrence of each species in the forest and in the nests. Forty-six(More)
The study of the archaeological remains of fossil hominins must rely on reconstructions to elucidate the behaviour that may have resulted in particular stone tools and their accumulation. Comparatively, stone tool use among living primates has illuminated behaviours that are also amenable to archaeological examination, permitting direct observations of the(More)
Monitoring populations of endangered species over time is necessary to guide and evaluate conservation efforts. This is particularly important for nonprotected areas that ensure connectivity between protected populations but are prone to uncontrolled hunting pressure. We investigated whether use of transects by local people and transect reuse for repeated(More)
We present an overview of a method for estimating an entire queueing function, &fnof;(&#955;), 0 &#8804; &#955; &lt; <italic>c</italic>, from a single simulation sample path, where &#955; is the arrival rate to the system and <italic>c</italic> is the system capacity. For example, &fnof;(&#955;) could be the average sojourn time in a queueing network as a(More)
