Conservation of Colombian primates: an analysis of published research

In Colombia, there are approximately 27-31 primate species, including at least five endemic ones and a high proportion of threatened species. Differences in these primates' distribution, abundance, ecology, and charisma, among many other things, have led to large variation in the amount and nature of investigations performed on the different species. Basic information on each native primate species is necessary to build adequate conservation plans; therefore, knowledge of the quantity and type of information available on each species can be helpful to identify possible research gaps. Based on publications from 1900 to 2008 on 25 primate species present in Colombia, we evaluated primate research in this country in terms of quantity, type, and topics of investigation. Additionally, we comparatively assessed the role of Colombian primatology within all scientific production on primate species present in this country. Our analyses indicate that in Colombia, primate research has developed mainly in the field-work area, with studies focused primarily on ecology and behavior. Investigations of topics such as karyology, anatomy, and physiology are very limited, and molecular biology is understudied compared to research on this subject in other countries. Captive studies are also comparatively scarce. Our analyses also suggest that those species distributed in areas where research stations are located have been the focus of a greater proportion of investigations. A few study sites (PNN La Macarena, Rio Peneya Station, PNN Tinigua, and Caparu Biological Station) stand out as primate research "hot-spots" within Colombia; however, field work in these stations is frequently jeopardized by the constant threat imposed by revolutionary armed forces in the rural and forested parts of Colombia.
