“…At Fongoli, Senegal, it is likely that chimpanzees have never had access to red colobus monkeys at this hot, dry and open site, although the range of red colobus monkeys (P.b. temminckii) in Senegal and adjacent countries in West Africa has diminished 3 . Fongoli chimpanzees are currently not sympatric with red colobus, although they eat vertebrate prey of various types, including a number of primate species.…”

“…Fifty percent ( N = 37) of the studies from southern Senegal came from the long-term research site of Fongoli ( McGrew, Pruetz & Fulton, 2005 ; Pruetz, 2006 ; Pruetz, 2007 ; Pruetz et al, 2015 ). The remaining studies mostly fell within the Niokolo-Koba NP ( Galat et al, 2000 ; Galat, Galat-Luong & Nizinski, 2009 ), particularly Mt. Assirik ( McGrew, Baldwin & Tutin, 1981 ; McGrew, Baldwin & Tutin, 1988 ; Baldwin, McGrew & Tutin, 1982 ; Harrison, 1983 ; Pruetz et al, 2012 ).…”

“…In Senegal red colobus were recorded along the Koulountou and Gambia Rivers, and one group was observed within the town of Kolda ( Galat, Galat-Luong & Nizinski, 2009 ). In Boké (Guinea), the species was only recorded in Badiar NP, along the Senegalese border, the N’Dama forest and Sangarédi ( Bailo, Alphonse & Gu, 2009 ; Galat, Galat-Luong & Nizinski, 2009 ; WCF, 2015b ). Red colobus were reported across southern Guinea-Bissau, with more recent studies coming from Cantanhez NP.…”

BackgroundWest African landscapes are largely characterised by complex agroforest mosaics. Although the West African forests are considered a nonhuman primate hotspot, knowledge on the distribution of many species is often lacking and out-of-date. Considering the fast-changing nature of the landscapes in this region, up-to-date information on primate occurrence is urgently needed, particularly of taxa such as colobines, which may be more sensitive to habitat modification than others. Understanding wildlife occurrence and mechanisms of persistence in these human-dominated landscapes is fundamental for developing effective conservation strategies.MethodsIn this paper, we aim to review current knowledge on the distribution of three threatened primates in Guinea-Bissau and neighbouring regions, highlighting research gaps and identifying priority research and conservation action. We conducted a systematic literature review of primate studies from 1976 to 2016 in Guinea-Bissau, southern Senegal and western Guinea (Boké Region). We mapped historical observation records of chimpanzee (Pan troglodytes verus), Temminck’s red colobus (Pilicolobus badius temminckii) and king colobus (Colobus polykomos), including our preliminary survey data from Dulombi, a newly established National Park (NP) in Guinea-Bissau.ResultsWe found 151 documents, including 87 journal articles, that contained field data on primates in this region. In Guinea-Bissau, nearly all studies focussed south of the Corubal River, including mainly Cantanhez, Cufada, and Boé NP’s. In Senegal, most of the data came from Fongoli and Niokolo-Koba NP. In Boké (Guinea) studies are few, with the most recent data coming from Sangarédi. In Dulombi NP we recorded eight primate species, including chimpanzees, red colobus and king colobus. Across the selected region, chimpanzees, red colobus and king colobus were reported in eleven, twelve and seven protected areas, respectively.DiscussionOur study demonstrates large geographical research gaps particularly for the two colobines. For the first time after more than two decades, we confirm the presence of red colobus and king colobus north of the Corubal River in Guinea-Bissau. The little information available from large parts of the red colobus range raises questions regarding levels of population fragmentation in this species, particularly in Casamance and across northern Guinea-Bissau. There are still no records demonstrating the occurrence of king colobus in Senegal, and the presence of a viable population in north-eastern Guinea-Bissau remains uncertain. While the occurrence of chimpanzees in Guinea-Bissau and Senegal is well documented, data from Boké (Guinea) are sparse and out-of-date. Our approach—the mapping of data gathered from a systematic literature review—allows us to provide recommendations for selecting future geographical survey locations and planning further research and conservation strategies in this region.

“…(2) High insectivory may be because of low diversity and abundance of appropriate vertebrate prey at Fongoli (Bogart,2009), and the abundance of termites here provides an opportunity for the chimpanzees to obtain necessary protein, nutrients, and amino acids (McGrew,1983; Pruetz and Bertolani,2007; Bogart and Pruetz,2008). A typical prey species for chimpanzees, the red colobus monkey ( Piliocolobus badius ) (Boesch,1994), is not found in the hot, dry environment at Fongoli (Galat et al,2009). The most common vertebrate prey is the bushbaby (Pruetz, unpublished data), but galago density (0.59/ha) is well below that of termite mounds (Bogart,2009).…”

Little is known about the behavior of chimpanzees living in savanna-woodlands, although they are of particular interest to anthropologists for the insight they can provide regarding the ecological pressures affecting early hominins living in similar habitats. Fongoli, Senegal, is the first site where savanna chimpanzees have been habituated for observational data collection and is the hottest and driest site where such observation of chimpanzees occurs today. Previously, indirect evidence suggested these chimpanzees consumed termites throughout the year, an unusual occurrence for western and eastern chimpanzees. Although meat eating by chimpanzees continues to receive much attention, their use of invertebrate prey has received less emphasis in scenarios of hominin evolution. Here, we further examine the invertebrate diet of Fongoli chimpanzees using direct observational methods and accounting for potential environmental influences. Termite feeding positively correlated with high temperatures. Fongoli chimpanzees spend more time obtaining termites than any other chimpanzee population studied, and this extensive insectivory contributes to the list of distinctive behaviors they display relative to chimpanzees living in more forested habitats. We suggest that savanna chimpanzees at Fongoli differ significantly from chimpanzees elsewhere as a result of the selective pressures characterizing their harsh environment, and this contrast provides an example of a viable referential model for better understanding human evolution. Specifically, our results support the hypotheses that invertebrate prey may have figured more prominently into the diet of early hominins in similar habitats, especially given that invertebrates are an important source of protein and other essential nutrients in a highly seasonal environment.
