Life history and age-dependent mortality processes in tropical reptiles
Hugo Cayuela, Godfrey C. Akani, Emmanuel M. Hema, Edem A. Eniang, Nioking Amadi, Stephanie N. Ajong, Daniele Dendi, Fabio Petrozzi, Luca Luiselli
Abstract Actuarial senescence appears to be a common process, and senescence patterns are highly variable across the tree of life. To date, studies on animal senescence have largely focused on model species, such as as fruit flies, humans and a few other endotherms. In contrast, our knowledge about ageing remains fragmentary in ectotherm verte(...)

Preliminary data on density and habitat of carnivores in two protected areas of Burkina Faso (West Africa)
Emmanuel M. Hema, Tinsgnimi Dialla, Djidama Sirima, Yaya Ouattara, Ismael M. Tou, Luca Luiselli
Abstract Apparent density [determined as kilometric index of abundance (KIA), by direct sightings and by droppings along line transects] and habitat use of some species of carnivore mammals were studied in two protected areas of Burkina Faso (Comoé-Leraba and Nazinga). Despite the fact that the dataset was collected throughout several years an(...)

Fabio Petrozzi, Emmanuel M. Hema, Gabriel Hoinsoudé Segniagbeto, Nioking Amadi, Godfrey C. Akani, Russell L. Burke, Laurent Chirio, Luca Luiselli
To better understand the habitat preferences of the African spurred tortoise (Centrochelys sulcata), we tested possible associations between their distribution and land use, vegetation cover, the presence of roads, human settlements, and rainfall patterns, all of which affect the distributions of other tortoise species. African spurred tortois(...)

Antimicrobial resistance has been declared a global threat to public health, as a massive increase in this problem has been observed worldwide. This study aims to investigate the role of class I integrons (Int1) in the dissemination of tetracycline and chloramphenicol resistance genes in Escherichia coli in rural Burkina Faso. A study was cond(...)

PROXIMATE ANALYSIS OF FIVE COWPEA [(Vigna unguiculata (L.) Walp.)] LINES AS FEED RESOURCES FOR RUMINANT PRODUCTION IN BURKINA FASO
Barro Antoine 1, Batieno Téyouré Benoit Joseph 2, Neya James Bougouma 2, Palé Korotoumou 1, 2, Jean Baptiste De La Salle Tignégré 3, Kaboré Adama *2, Sawadogo Mahamadou 4
The main food resource for ruminant production in Burkina Faso is natural grazing, which cannot
sustain ruminant production all year round. Therefore, it is necessary to incorporate cultivated
forages including crop residues such as fodder whose nutritional values must be verified before
they are used in ruminant feed. To this end, samples(...)

Aboveground biomass allometric equations and distribution of carbon stocks of the African oak (Afzelia africana Sm.) in Burkina Faso
Larba Hubert Balima, Blandine Marie Ivette Nacoulma, Philippe Bayen, Kangbéni Dimobe, François N’Guessan Kouamé, Adjima Thiombiano
The significant role of tropical forest ecosystems in the global carbon budget has increased the need for accurate estimates of tropical forest biomass. The lack of large-scale biomass allometric equations hampers the understanding of the spatial distribution of tree biomass and carbon stocks and their influencing factors in West Africa. This(...)

Population dynamics and age-dependent mortality processes in tropical reptiles
Hugo Cayuela, Godfrey C. Akani, Emmanuel M. Hema, Edem A. Eniang, Nioking Amadi, Stephanie N. Ajong, Daniele Dendi, Fabio Petrozzi, Luca Luiselli
Abstract Understanding age-dependent mortality processes is a critical challenge for population biologists. Actuarial senescence appears to be a common process across the tree of life. Senescence patterns are highly variable in pluricellular organisms: senescence can be gradual or sharp and its onset may be early or delayed. By contrast, studi(...)

Epidemiology and Resistance Phenotypes of Salmonella spp. Strains Responsible for Gastroenteritis in Children less than Five Years of Age in Ouagadougou, Burkina Faso
Ali Konaté, Nathalie Guessennd, Fernique Konan Kouadio, Réné Dembelé, Assèta Kagambèga, Innocent Kouamé Kouadio, Haoua Cissé, Mohamed Baguy Ouattara, Wendpoulomdé Ad Kaboré, Tiékoura Konan Bertin, David Coulibaly N’golo, Alfred S. Traoré, Nicolas Barro
Conventional treatment of children with severe gastroenteritis is based on antibiotic therapy. Due to the emergence of Multi-Drug resistant bacteria and pediatric therapeutic failures, this study was undertaken to determine resistance phenotypes of Salmonella spp. responsible for children, gastroenteritis.

Water stress tolerance potential of five priority species for afforestation in Burkina Faso.
François Wenemi Kagambèga, Rasmata Nana, Philippe Bayen, Adjima Thiombiano, Joseph Issaka Boussim
Description du sujet. Dans les régions arides et semi-arides, la disponibilité en eau est l’un des facteurs limitant de la croissance et du développement des arbres. L’étude de la réponse au déficit hydrique des espèces végétales permettrait de sélectionner du matériel végétal résistant pouvant se développer dans les zones sujettes à des défic(...)

ANALYSE DE QUELQUES NÉOGRAPHISMES PUBLICITAIRES AU BURKINA FASO
OUEDRAOGO Youssouf et DAÏLA Béli Mathieu
La pratique du français en contexte naturel se particularise du français standard à
l’écrit et à l’oral. Dans cet article, il est question de la formation des mots sur les
affiches et enseignes publicitaires et les infographies télévisuelles. En effet, les
mots sont formés de lettres, de chiffres et ne tiennent compte que de la phonie.

Effects of Water Quality and Post-Harvest Handling on Microbiological Contamination of Lettuce at Urban and Peri-Urban Locations of Ouagadougou, Burkina Faso
Juliane Dao, Kathrin Stenchly, Oumar Traoré , Philip Amoah and Andreas Buerkert
Vegetable production in urban gardens of Ouagadougou contributes to food security, but
water for irrigation is often of low quality. This is particularly acute if irrigation water is taken
from wastewater polluted channels. This study aimed at (i) verifying to what degree irrigation
water quality is correlated with contamination of lettuce(...)

Abstract There is an unprecedented demand for bushmeat in large cities in sub-Saharan Africa, and this is a major threat to many species. We conducted 2,040 interviews in six cities in four West African countries, in forest and savannah settings. We analysed age- and sex-related differences in the frequency of bushmeat consumption. Overall, we(...)

Madi Savadogo, Adama Sow, Laibané Dieudonné Dahourou, Aurélie Cailleau, Miguiri Kalandi, Germain Jérôme Sawadogo
Le virus de la peste équine africaine (PEA) provoque des épizooties sévères lorsqu’il est transmis aux chevaux par ses vecteurs, les culicoïdes. Une étude transversale a été réalisée dans cinq régions du Burkina Faso afin de déterminer la séroprévalence du virus chez les ânes et d’identifier les facteurs de risque potentiel. Au total, 460 séru(...)
