Background: African pangolins are currently experiencing unprecedented levels of harvesting, feeding both local demands and the illegal international trade. So far, the lack of knowledge on the population genetics of African pangolins has hampered any attempts at assessing their demographic status and tracing their trade at the local scale. We con...

Understanding what shapes the mammal species poaching in protected areas is critical to developing targeted management strategies for reducing poaching. We collected the data for poaching incidents on the GPS coordinates from 2011 to 2017 to map poaching incidents in the Pendjari Biosphere Reserve. Poaching incidents were then related to environmen...

Illegal hunting of wildlife is one of the major issues in tropical ecosystems, especially when it occurs in highly degraded habitats with forest cover fragmentation. In this study, we assessed the impact of bushmeat hunting in a large forest patch (the Lama Natural Forest; LNF) and 11 nearby forest islands, using Traditional Ecological Knowledge fr...
Article
Tree hyraxes (Dendrohyrax) are one of only three genera currently recognized in Procaviidae, the only extant family in the mammalian order Hyracoidea. Their taxonomy and natural history have received little attention in recent decades. All tree hyrax populations of Guineo-Congolian forests of Africa are currently treated as a single species, Dendro...

We are an international group of biological scientists, conservationists, and environmentalists who have been closely following the plight and conservation of pangolins over a number of years. Pangolins comprise the mammalian Order Pholidota, which contains eight living species found in diverse habitats in Africa (4 species) and Asia (4 species), w...
Thesis
Full-text available
This thesis endeavours to understand how grazing and browsing herbivores co-exist, with special emphasis on understanding the mechanisms of competition and facilitation over temporal and spatial scales. We focused on feeding ecology and habitat use study of the free ranging bovid species of Pendjari Biosphere Reserve in Northwestern Benin. Here we...

We conducted in the Dahomey Gap (DG) a pioneer study on the genetic tracing of the African pangolin trade. We sequenced and genotyped 189 white-bellied pangolins from 18 forests and 12 wildlife markets using one mitochondrial fragment and 20 microsatellites loci. Tree-based assignment procedure showed the ‘endemicity’ of the pangolin trade, as stri...
Article
Identification and assessment of the influence of socio-cultural beliefs in the perception of ecosystem services values are increasingly important for the management of forest resources. In this paper, we present a comparative study of local perceptions of the diversity of ecosystem services, values and priorities between communities living near sa...
Article
Full-text available
Health risks associated to the use of tropical wildlife have so far been envisioned through the lens of zoonotic pathogens spread by the bushmeat trade, putting aside the equally vibrant network of traditional medicine markets (TMMs). We collected information on the preservative techniques used for animal body parts from TMMs in Benin through a sem...
Article
Full-text available
Background Pangolins are trafficked in unsustainable volumes to feed both local and global trade networks for their meat and the medicinal properties of their derivatives, including scales. We focus on a West African country (Benin) to assess the medicinal and spiritual values of pangolins among different ethnic groups and identify the cohort of bu...

In a context of fragmentation of forest landscape and sustainable use of orchid species, an analysis of the local knowledge base is necessary for developing conservation strategies of orchid habitat. This study aims at i) assessing factors affecting local perception on conservation status of orchids, and ii) determining degradation factors of their...
Article
Understanding factors limiting rare species is a major concern in conservation ecology. Little is known about how large mammalian bovid species from West Africa partition diet resources, and to what extent the rare topi antelope and other sympatric bulk grazers can cope with this co-existing system. Using tooth collagen stable isotope data, we stud...

Hunting is an important activity for the survival of local communities. However, unregulated hunting threatens the sustainability of wildlife and subsequently affects the same populations. This study investigated bushmeat hunting practices and their implications in wildlife sustainable management in Bobo-Dioulasso (Burkina-Faso). A total of 226 hun...

Full-text available
Although pangolins are considered to be one of the most trafficked wild mammals in the world, their conservation status remains uncertain through most of their ranges, and notably in western Africa. Using local ecological knowledge in combination with direct occurrence evidence, we assessed the distribution and abundance of the white-bellied pangol...

The silver butter catfish (Schilbe intermedius) is widely distributed across African river systems. To date, information on its mitochondrial genetic diversity, population structure, and historical demography are not well-established. Herein, we combined newly generated mitochondrial cytochrome c oxidase (COI) subunit I gene sequences with previous...

Spotted-necked otters (Hydrictis maculicollis) are present in several major river systems in southern Benin, and their environmental requirements link them to food and water security issues as the region is so densely populated by humans. The lack of baseline data on their distribution and ecology is another major constraint that the species is fac...

The effectiveness of protected areas to guarantee future conservation of several plant species remains questionable. This study was carried out in the Biosphere Reserve of Pendjari (BRP) and surrounding unprotected areas to assess the efficiency of the reserve to conserve orchids. A total of 90 plots (52 in protected areas; 38 in unprotected areas)...

In Benin, people have a rich ethnobotanical knowledge of plant species, reflecting the cultural and ecological diversity of their environment. Several studies were focused on the question of how valuable are plant species for local communities. However, there has been very little research interest in the orchid species in spite of the importance of...

Knowledge on faunal diversification in African rainforests remains scarce. We used phylogeography to assess (i) the role of Pleistocene climatic oscillations in the diversification of the African common pangolin (Manis tricuspis), and (ii) the utility of our multi-locus approach for taxonomic delineation and trade tracing of this heavily poached sp...
Article
Understanding the mechanisms of species coexistence within local assemblages can play a crucial role in conservation of a species. There is little understanding of how large mammalian bovid species from West Africa partition diet resources, and to what extent they may vary their diet and habitat selection seasonally in order to coexist.

The spotted-necked otter (Lutra maculicollis) is believed to be declining across its range and, in Benin, has recently been listed as endangered. In Benin, the spotted-necked otter is largely restricted to the south of the country, where it is threatened by a number of factors, including conflict with fishermen. Understanding the nature and extent...

Bovid diets have been studied for decades, but debate still exists about the diets of many species, in part because of geographical or habitat-related dietary variations. In this study we used stable carbon isotope analyses of faeces to explore the seasonal dietary preferences of 11 bovid species from a West African savanna, the Pendjari Biosphere...
