New technologies enable viral discovery in a diversity of hosts, providing insights into viral evolution. We used one such approach, the virome capture sequencing for vertebrate viruses (VirCapSeq-VERT) platform, on 21 samples originating from six dead Maxwell’s duikers (Philantomba maxwellii) from Taï National Park, Côte d’Ivoire. We detected the presence of an orthohepadnavirus in one animal and characterized its 3128 bp genome. The highest viral copy numbers were detected in the spleen, followed by the lung, blood, and liver, with the lowest copy numbers in the kidney and heart; the virus was not detected in the jejunum. Viral copy numbers in the blood were in the range known from humans with active chronic infections leading to liver histolytic damage, suggesting this virus could be pathogenic in duikers, though many orthohepadnaviruses appear to be apathogenic in other hosts, precluding a formal test of this hypothesis. The virus was not detected in 29 other dead duiker samples from the Côte d’Ivoire and Central African Republic, suggesting either a spillover event or a low prevalence in these populations. Phylogenetic analysis placed the virus as a divergent member of the mammalian clade of orthohepadnaviruses, though its relationship to other orthohepadnaviruses remains uncertain. This represents the first orthohepadnavirus described in an artiodactyl. We have tentatively named this new member of the genus Orthohepadnavirus (family Hepadnaviridae), Taï Forest hepadnavirus. Further studies are needed to determine whether it, or some close relatives, are present in a broader range of artiodactyls, including livestock.

Objectifs : Des investigations ont été menées dans 11 sites du lac de Buyo situés sur le cours du fleuve Sassandra dans le Parc National de Taï (Côte d’Ivoire) en vue de connaître les espèces de poisson qui utilisent ces zones comme sites de reproduction. Méthodologie et Résultats : Dans chaque site d’échantillonnage, les variables environnementales ont été mesurées et les poissons ont été capturés à l’aide de filets maillants. Les stades de maturité sexuelle avancés ont été considérés comme critères de reconnaissance des sites de fraie. La richesse spécifique a été de 32 espèces, répartie en 13 familles et dominée par les Cichlidae (7 espèces, soit 22%). Sur la base des stades sexuels de maturité, 14 espèces, en phase de reproduction, ont été capturées dans les 11 sites d’échantillonnage. Les résultats de l’analyse des sédiments ont indiqué une prédominance de sable (>60%) dans les sites de reproduction et des valeurs optimales de température (28,52°C), de pH (6,53), de conductivité (36,50 μS/cm) et d’oxygène dissous (5,37 mg/l). Conclusion et application des résultats : La présente étude a montré que les sites échantillonnés dans le lac de Buyo situé à l’intérieur du le Parc National de Taï sont caractérisés par des sédiments sableux et constituent des frayères pour plusieurs espèces de poisson. La localisation de ces zones de reproduction représente donc un outil important pour les gestionnaires dans la conservation de la diversité piscicole du parc national de Taï. Mots clés : sites de frai, stade de maturité sexuelle, ichtyofaune, lac de barrage de Buyo. Specific inventory and characteristics of some spawning grounds of Lake Buyo in the Taï National Park (South-West Côte d'Ivoire) Abstract Objectives: Investigations were carried out in 11 sites of Lake Buyo located in the midstream of Sassandra River in Taï National Park (Côte d'Ivoire) to get to know fish species that use these areas as spawning sites. Methodology and Results: Environmental variables were measured in each sampling sites and fish were caught using gillnets. Advanced stages of sexual maturity were considered as recognition criteria of spawning areas. Specific richness was of 32 species, belonging in 13 families and dominated by Cichlidae (7 species, 22%). Based on advanced sexual maturity stages, 14 species in spawning period, were captured at the 11 sampling sites. Results of sediment analysis indicated a predominance of sand (> 60%) in spawning sites and optimal values of temperature (28.52°C), pH (6,53), conductivity (36,50 μS/cm) and dissolved oxygen (5,37 mg/l). Conclusion and application of results: The present study showed that sites sampled in Lake Buyo located within the Tai National Park are characterized by sandy sediments and constitute spawning areas for several fish species. The location of these spawning areas therefore is an important tool for managers in conserving fish diversity of Taï National Park. Keywords: spawning sites, stage of sexual maturity, Ichtyofauna, Buyo Dam Lake.

AbstractDistance sampling, line transects and radio-tracking have been used previously to estimate population abundances and movements of hornbills. We used a large dataset of audio recordings made over 10 years to estimate seasonal variation in abundance of three species: Black-casqued Hornbill Ceratogymna atrata, Yellow-casqued Hornbill C. elata and Brown-cheeked Hornbill Bycanistes cylindricus, in Taï National Park, Côte d'Ivoire. The latter two species are Near Threatened. Recordings of hornbill wing-beats were used to control for potential seasonal variation in call production. Yellow- and Black-casqued Hornbill calls were 10 times as abundant from July to February as they were from March to June. Brown-cheeked Hornbills showed a similar trend, but less pronounced. From these data we concluded that large numbers of Yellow- and Black-casqued Hornbills had left the Taï National Park during this period. The significance of these findings is discussed in relation to the fragmentation and regeneration of the Upper Guinea forests and the relatively small size of the remaining forest habitat in the region.Les taux d'abondance et de mouvement des populations de calaos étaient auparavant estimés par un échantillonnage et des analyses sur le logiciel Distance, des transects linéaires et des repérages télémétriques. Nous avons eu recours è un grand ensemble d'enregistrements audio effectués sur plus de 10 ans afin d'estimer la variation saisonniàre de l'abondance de trois espàces rencontrées dans le Parc National de Taï, en Côte d'Ivoire : le Grand Calao è Casque Noir Ceratogymna atrata, le Grand Calao è Casque Jaune Ceratogymna elata et le Calao è Joues Brunes Bycanistes cylindricus. Ces deux derniàres espàces sont aujourd'hui considérées comme presque menacées. Nous avons procédé è des enregistrements de battements d'ailes pour tester une potentielle variation saisonniàre de la production des cris. Les cris des Grands Calaos è Casque Jaune et è Casque Noir étaient dix fois plus abondants entre juillet et février qu'entre mars et juin. En revanche, les Calaos è Joues Brunes n'ont présenté qu'une petite variation du taux d'abondance entre ces deux périodes. D'apràs ces données, nous avons conclu qu'un grand nombre de Calaos è Casque Jaune et è Casque Noir quittent le Parc National de Taï entre mars et juin. La signification de ces découvertes est discutée en tenant compte de la fragmentation et de la régénération des forêts de Haute Guinée ainsi que de la dimension relativement petite de l'habitat forestier subsistant dans cette région.

The Impact

AbstractConsumption of bushmeat, a staple food of people living in the vicinity of protected areas, is a challenge for the conservation of wildlife. The underlying factors driving this consumption are, however, relatively understudied, particularly among rural households, and improved understanding would facilitate the development of conservation strategies. We therefore aimed to identify the factors that influence bushmeat consumption in rural households to the west of Taï National Park, in Côte d'Ivoire. We carried out enquiries in a total of 144 rural households in 20 localities during July–December 2012. Bushmeat, the majority of which comprised rodents and bovids, accounted for 13% of the animal protein consumed in these households. This consumption was significantly higher in households in which poverty was more acute (low annual income and more dependent children). We found that repeated awareness campaigns involving theatre performances and/or film screenings (multimedia campaigns) contributed to a decrease in bushmeat consumption. This decrease exceeded 62% after exposure to four multimedia campaigns. We highlight the importance of awareness campaigns for reducing consumption of wild animals, and demonstrate the importance of recurring multimedia campaigns to maximize the impact of such conservation activities in rural communities.

AbstractIn recent years, new applications of microremain dietary analysis using dental calculus as a source of dietary data on ancient human subsistence and behaviours have accelerated. The dental calculus of contemporary human and non-human populations with known diets have been used as reference datasets, including the chimpanzees of Taï National Park (Côte d'Ivoire), but explaining the preservation mechanism involved is challenged by our incomplete knowledge of the microremain content within the diets of these reference populations and our rudimentary information on microremain incorporation into dental calculus. Here, we analyse phytoliths in faecal samples to assess to what extent plant phytoliths of a diet are reflected in the dental calculus as well as in the egested faeces. In this study, we identify and document the faecal phytolith assemblages as an indicator of plant consumption in two Western chimpanzees of the Taï National Park (Côte d'Ivoire) before (wet season), during (dry season) and after (dry season) a dust-rich period. Moreover, observational dietary records of these two individuals were compiled to improve the interpretability of this dental calculus phytolith dataset. The faecal phytolith assemblages vary significantly across samples in terms of abundance and diversity. The most common phytolith morphotypes were eudicot plates, single-cell and multi-cell tracheids, monocot rugulose and echinate spheroids and, to a lesser extent, unspecified thick and thin elongates. High loads of grit and other micro-remains (e.g. diatoms) are found during the dry period. Using observational dietary records as a starting point and our faecal results as a terminus, we consider how dental calculus can accumulate phytoliths. Our findings enable identification of the phytolith morphotypes that are under-represented in dental calculus, which is highly informative for future dental calculus research strategies.

Little information is available on the prevalence of retrovirus infections in populations of non-human primates living in their natural habitats. To gain such information, methods were developed to detect antibodies to simian T-lymphotropic virus type 1 (STLV-1) in urine from wild chimpanzees. Samples from more than 74 chimpanzees living in three communities in the Taï National Park, Côte d'Ivoire, were analysed. The prevalence of STLV-1 antibodies in adults and adolescents was significantly higher (35/49, 71·4 %) than that in infant and juvenile chimpanzees (3/31, 9·7 %).
