- Notes on the conservation threats to the western lesser spot-nosed monkey (Cercopithecus petaurista buettikoferi) in the Bijagós Archipelago (Guinea-Bissau, West Africa)Publication . Colmonero Costeira, Ivo; Sá, R. M.; Djaló, M. L.; Cunha, N.; Cunha, J.; Minhós, T; Russo, Isa-Rita; Bruford, Michael; Costa, Susana; M, Ferreira Da SilvaThe lesser spot-nosed monkey (Cercopithecus petaurista) is a widely distributed West African guenon, which is generally considered less vulnerable to local extinctions than many sympatric primate species. Guinea-Bissau harbours the westernmost populations of the species, which is thought to be very rare or even extinct on the mainland, but to have putative populations on some islands of the Bijagós Archipelago. However, due to a lack of regional studies, baseline information on these insular populations is missing. We collected baseline data on the anthropogenic activities that possibly threaten the long-term con servation of this primate by using non-systematic ethnographic methodologies. The species was reported to be decreasing in number or rare by locals on two of the islands, and we identifed two main conservation threats to it: generalised habitat loss/ degradation, and hunting. While subsistence hunting has been recorded before in these areas, we report, to the best of our knowledge for the frst time for these islands, the presence of a semi-organised commercial wild meat trade. The carcasses of western lesser spot-nosed monkeys were observed being stored and shipped from seaports to be sold at urban hubs (Bissau and Bubaque Island). The efect of commercial trade on the species could be severe, considering the small, naturally occur ring, carrying capacities typical of insular ecosystems. The results of this study highlight the importance of understanding the leading social drivers of wild meat hunting of lesser spot-nosed monkeys on the Bijagós Archipelago, and the need to conduct baseline research on these insular populations, for which qualitative and quantitative methods could be combined.
