a field observation of sclater's guenon (cercopithecus sclateri pocock, 1904).		1989	2807098
distribution and abundance of sacred monkeys in igboland, southern nigeria.	although primates are hunted on a global scale, some species are protected against harassment and killing by taboos or religious doctrines. sites where the killing of sacred monkeys or the destruction of sacred groves is forbidden may be integral to the conservation of certain species. in 2004, as part of a distribution survey of sclater's guenon (cercopithecus sclateri) in southern nigeria, we investigated reports of sacred monkeys in the igbo-speaking region of nigeria. we confirmed nine new s ...	2009	19408287
sacred populations of cercopithecus sclateri: analysis of apparent population increases from census counts.	the development of effective conservation and management actions for populations of wild species generally requires monitoring programs that provide reliable estimates of population size over time. primate researchers have to date given more attention to evaluating techniques for monitoring primates in natural habitats compared to populations that occur in villages or urban areas. we conducted censuses to estimate the abundance and density of two sacred, village-dwelling populations (lagwa and a ...	2014	24282131
africa's primates in 1992: conservation issues and options.	there are about 60 species of african primates, and over 50% of these are generally considered to be vulnerable to extinction. planning for the conservation of these primates, and the objective assessment of the degree of endangerment faced by different species and subspecies is hampered, however, by poorly resolved taxonomy and inadequate data on geographic distributions, ecology, and population biology. the african primate species at most imminent risk of extinction may be sclater's guenon, th ...	1994	31936978
