On the western fringe of baboon distribution: mitochondrial D-loop diversity of Guinea Baboons (Papio papio Desmarest, 1820) (Primates: Cercopithecidae) in Coastal Guinea-Bissau, western Africa -- Maria J. Ferreira da Silva, Catarina Casanova & Raquel Godinho, Pp. 4441–4450 DOI: dx.doi.org/10.11609/JoTT.o3216.4441-50 Highlights 1) We assessed genetic diversity levels and population structure for the Guinea baboon (Papio papio), a poorly known and threatened species. 2) We collected non-invasive samples from two locations in Guinea-Bissau - Cufada Lagoons Natural Park (CLNP) and Cantanhez Forest National Park (CNP). 3) Among closely related mtDNA haplotypes, we found a very divergent haplotype (2.3% divergence), suggesting the presence of a contact zone between genetically differentiated populations in CLNP. 4) No significant genetic differentiation was found between sampling locations, possibly due to common ancestral origin or frequent dispersal of individuals. 5) The presence of different maternal lineages and a higher percentage of variation within social units suggested historical female-biased dispersal for Guinea-Bissau baboons. 6) Guinea baboons presented lower haplotype, nucleotide and theta diversity than Hamadryas baboons. 7) Guinea-Bissau baboons probably went through a past population bottleneck or a rapid colonisation or re-colonisation events by few or genetically similar individuals. 8) This study supports the need for additional genetic studies within the full Guinea baboons range.
