Biogeographic analysis of the composition of the mammalian fauna of Togo (West Africa)
The Dahomey Gap in West Africa is a human-derived savannah-like vegetation zone interspersed by patches of moist forest, with large rainforest blocks at both West (Upper Guinean Forest) and East (Lower Guinean Forest) of its limits. Togo is a tiny country situated in the middle of the Dahomey Gap. In this paper, a biogeographic analysis of the composition of the mammalian fauna of Togo is presented, by classifying each species on the basis of five distinct ecological distribution patterns. The greatest proportion of species were Pan-African (88.0%). Excluding the Pan-African species from the analysis, the mammalian fauna appeared to be affiliated similarly to both Upper Guinean and Lower Guinean Forest blocks. Only three endemic species were observed, all of them being rodents: Cryptomys zechi (Batyergidae), Funisciurus substriatus (Sciuridae), and Leimacomys buettneri (Muridae). Considering only the multispecies genera, the great majority did not show any barrier effect by the Dahomey Gap on their own species, as all of them did occur on both sides of Togo. A barrier effect by the Dahomey Gap was uncovered in 8 genera; overall, the Dahomey Gap apparently showed a barrier effect on 28.6% of the multispecies genera. It is emphasized that the full understanding of the role of the Dahomey Gap as a biogeographic barrier and of its island forests as centers of endemism is impeded by the lack of biogeographic reviews and meta-analyses on the composition of faunal and floral groups of the entire region
Snake oil and pangolin scales: insights into wild animal use at “Marché des Fétiches” traditional medicine market, Togo
Traditional medicine beliefs are culturally important in some West African communities, where there is a thriving domestic consumer demand for wild animal derivatives. Yet, such practices can threaten the conservation of wild populations and negatively impact animal welfare. To identify those species most likely to be affected, we investigated wildlife derivative trade at the largest fetish market of West Africa in Togo. Specifically, we asked what wild animals or animal products were most profitable, which wild animals were perceived by vendors to have increased most in rarity and what they were used for. A key question was whether vendors also sold plant-based alternatives. Vendors provided 36 local animal names, from which we inferred an estimated 281 species. Thirteen percent of these inferred species are categorised on the IUCN Red List as threatened (n = 35); 26% are declining (n = 72). The most commonly cited most profitable wildlife derivatives were “Pangolin” and “Python”; the most commonly cited most profitable live wild animal was “Chameleon”. Overall, wildlife use was predominantly spiritual rather than medicinal. Plant-based alternatives were available, but comprised < 40% of sales and appeared to be considered less important or less useful than wild animal products. The legal status of this domestic trade in Togo is unclear given the existence of potentially conflicting national legislation. In addition to further research focused on the actual impacts on populations and individuals of the species indicated, socio-economic importance of this trade, societal pressures driving consumer demand and an assessment of the feasibility of sustainable plant-based alternatives is warranted
Trade in African Grey Parrots for Belief-Based Use: Insights From West Africa's Largest Traditional Medicine Market
Over 1.2 million wild-sourced African Grey parrots (Psittacus erithacus) have reportedly been traded internationally since the 1970s, the majority of which were taken from the wild with serious implications for conservation, animal welfare, and biosecurity. While international trade has mostly been for the pet trade, in some West African countries, Grey parrots are also consumed for belief-based use. However, to date there has been little research into the scale and scope of this trade and its drivers. Here, we explore multiple facets of the trade in Grey parrots for belief-based use through interviews with five vendors at the largest “fetish” market of West Africa in Togo. We focus on understanding the purpose of medicinal and spiritual use of Grey parrots, and the socio-economic dimensions of this trade. Parrot heads were the most valuable and most frequently traded body part over the last year (2017), sold primarily for the medicinal purpose of helping to “improve memory.” Feathers were the most common transaction for spiritual use, largely purchased for “attracting clients”, “love”, and to “help with divorce”. Whole parrots and parrot heads had also been traded for spiritual use, mainly for “good luck” and “protection from witchcraft”. Our findings suggest ~900 Grey parrots were traded over the past 10 years in the market. Most vendors perceived an increase in the rarity of Grey parrot body parts over the past 5 years, which may reflect increased restrictions on international trade and/or the deteriorating state of wild populations. Although the sale of feathers collected from beneath roosting sites does not negatively impact wild populations, the relatively low value of these parts compared with other parrot derivatives and live parrots, suggests there may be minimal opportunity to leverage market mechanisms to protect wild populations through sustainable use. We identify a need for further investigations to examine the complex relationship between capture to supply the international pet market, a process in which many parrots die, and the local trade in belief-based use of derivatives
Ecological challenges for the buffer zone management of protected areas of forest-savannah mosaic in West Africa
In sub-Saharan Africa, the management of buffer zones around protected areas does not often take into serious account the needs of resource exploitation by the local populations or the conservation needs of these areas. We described the ecological characteristics and management issues affecting the buffer zone around the Fazao-Malfakassa National Park; a 192,000-ha protected area in central-western Togo of utmost conservation importance within the Dahomey Gap region. Within the buffer zone (10 km radius, 334,800 ha), we focussed on four high conservation value areas totalling 65,594 ha (20% of the total buffer zone area). Using 2015 sentinel-2 images we analyzed land cover patterns and described existing ecological zones. We complemented these with field surveys and interviews with 300 people living in 22 villages within the buffer zone to describe the conditions affecting the resident human population. Although over 60% of the total buffer zone area is degraded, we identified four areas of high conservation value (total area = 65,594 ha). Interviewees recognized that slash-and-burn was the most common form of land use, followed by agroforestry practices. Agriculture, charcoal, and firewood production were the main drivers affecting habitats, and land conflicts were recurrent due to the rise in human population. The decline in agriculture, reported by interviewees in some sectors, was attributable to ravages of crops by elephants. Three independent diversity indices showed that, in preserved zones, a greater diversity of animals (with similar utilization frequencies) were hunted than in degraded sites (where grasscutters were the dominant hunted species). There were also significant differences between degraded and preserved zones in terms of plants used for charcoal production and for non-timber forest products. We advocate the development of community-controlled hunting areas to enhance the conservation value of the four well-preserved zones. Instead, promoting sustainable agricultural production systems in the degraded areas can help to further stabilize the agricultural front and reduce land pressure on the park

Camera trap survey of mammals in the Fazao-Malfakassa National Park, Togo, West Africa
For the first time in Togo, we used camera trapping to investigate the mammal community in Fazao-Malfakassa National Park (FMNP), a forest and savannah mosaic landscape subject to poaching and other detrimental anthropogenic activity. We compiled a species inventory, that is species occurrence, habitat use and activity patterns during dry and wet seasons. Based on images from >80 locations during 9,007 camera days, we identified 32 mammal species, which, when combined with other published studies, increases the total number of mammals (excluding bats) historically reported to 57 species. Our results confirm the presence of five mammal species evaluated as threatened according to the IUCN Red List, highlighting the significant conservation value of the FMNP. Specifically, it appears to be the only protected area in Togo where the African savannah elephant and the African forest elephant occur sympatrically, and only the second site currently known with direct observations of Walter's duiker. We also report the presence of poachers and other anthropogenic activity within the FMNP. We recommend that continued survey efforts should be combined with detailed ecological data collection, effective law enforcement, community outreach and eco-tourism development, to safeguard the remaining mammal species communities necessary for a functioning ecosystem in the park

Local distribution and density estimates of primates in the transboundary reserve of the Mono river, Togo (west Africa)
The reserve of biosphere of Mono river is located in the Dahomey Gap, which is the relatively arid interruption in the West African forest belt that stretches from the Accra Plains in Ghana across the Volta River through Togo to the eastern border of Benin. This West African climate discontinuity is characterized by mosaics of dense semi-deciduous forests, Guinean savannahs, swampy meadows, marshes, mangroves and bodies of water, mosaics of agroforest, farms and fallow land. In this reserve, centered on the Mono valley between Togo and Benin, with 2042.18 km² area, we assessed the status of populations of primate species. Overall, 9 species were recorded : Galago senegalensis, Galagoides demidoff, Perodicticus potto, Papio anubis, Colobus vellerosus, Cercopithecus erythrogaster erythrogaster, Cercopithecus mona, Erythrocebus patas and Chlorocebus tantalus.
The populations of these species are distributed in four basic units of the reserve : the Asmara forest, the Togodo protected area complex, the Godjé-Godjin sacred forest and the Akissa sacred forest. Our works clearly established a seasonal and regular displacement of primate species populations among different ecological units. The Togodo protected areas complex is the sanctuary for primate populations in southern Togo and Benin, and mainly for the Red-bellied Monkey (Cercopithecus erythrogaster erythrogaster), which is considered a Critically Endangered species on the IUCN Red List.Distribution locale et estimation des densités des primates dans la réserve transfrontalière du fleuve Mono, Togo (Afrique de l’Ouest).
La réserve de biosphère de Mono est située dans le «Dahomey Gap» qui sépare la ceinture des forêts denses humides ouest-africaines en deux blocs forestiers : guinéen (occidental) et congolais (oriental). Cette discontinuité climatique dahoméenne est caractérisée par des mosaïques de forêts denses semi-décidues, des savanes guinéennes, des prairies marécageuses, des marais, des mangroves et des plans d’eau, des mosaïques d’agroforêts, champs et jachères. Dans cette réserve centrée sur la vallée du Mono entre le Togo et le Bénin, d’une surperficie de 2042,18 km2, nous nous évalué le statut des populations des espèces de primates. Au total, 9 espèces ont été recensées : Galago senegalensis, Galagoides demidoff, Perodicticus potto, Papio anubis, Colobus vellerosus, Cercopithecus erythrogaste erythrogaster, Cercopithecus mona, Erythrocebus patas et Chlorocebus tantalus. Les populations de ces espèces sont distribuées dans quatre unités fondamentales de la réserve : la forêt d’Asrama, le complexe d’aires protégées de Togodo, la forêt sacrée de Godjé-Godjin et la forêt sacrée d’Akissa. Les travaux ont clairement établi un déplacement saisonnier et régulier des populations de ces espèces de primates dans ces différentes unités écologiques. Le complexe d’aires protégées de Togodo constitue le sanctuaire pour les populations de primates dans le Sud du Togo et du Bénin et principalement celle du Hocheur à ventre roux (Cercopithecus erythrogaster erythrogaster) considéré comme espèce en danger critique sur la liste rouge de l’UICN.Segniagbeto Gabriel, Atsri Komina H., Delagnon Assou, Komla Elikplim Abotsi, Kokouvi Gbetey Akpamou, Amori Giovanni, Dendi Daniele, Decher Jan, Luiselli Luca.
