Identification of Polymorphic Microsatellite Markers Linked to Cowpea Resistance to Cowpea Aphid Borne Mosaic Virus (CABMV) in Burkina Faso
Barro Antoine1*, Tignegre Jean Baptiste De La Salle2, Kiebre Zakaria1, Drabo Issa3 and Sawadogo Mahamadou1
Cowpea is rich in proteins and contains essential amino acids. It is used for
nutrition. For the producers, it is an important source of incomes. Cowpea is mainly
grown for its grains, its leaves, its young pods. However several viral diseases
attack cowpea. The most dangerous one is yellow mosaic transmitted by aphids or

Evaluation of Cowpea Resistance to Cowpea Aphid Borne Mosaic Virus in Burkina Faso
Antoine Barro, Mahamadou Sawadogo, Zakaria Kiébré, Bouma James Néya
Cowpea, Vigna unguiculata [L] Walp, is one of the most important grain legume grown in all arid and semi-arid regions of Africa. It contributes to reduce malnutrition and poverty and to achieve food security as well. However, cowpea production is hampered by many biotic and abiotic stresses which include viral diseases. Cowpea mosaic caused by(...)

Occurrence and Antibiotic Susceptibility of Aerococcus and Enterococcus Strains Isolated from Acute and Chronic Cellulites of Dental Origin in Ouagadougou, Burkina Faso
Kaboré WAD, Ali Konaté, Réné Dembelé, K Konaté, B. Faye, Dieu‐Donné Ouedraogo, Sylvie Boisramé, Traoré AS, Nicolas Barro, Lassana Sangaré
Cellulites of dental origin are extensive polymicrobial infections of the face and neck cell-adipose tissues. Management of infections of this nature presents significant challenges. The key to this is the identification of the causative organisms and determination of their susceptibility to antibiotics. Enterococcus and Aerococcus are pathoge(...)

Aspects of natural history in a sand boa,Eryx muelleri(Erycidae) from arid savannahs in Burkina Faso, Togo, and Nigeria (West Africa)
Leonardo Vignoli, Gabriel Hoinsoudé Segniagbeto, Edem A. Eniang, Emmanuel M. Hema, Fabio Petrozzi, Godfrey C. Akani, Luca Luiselli
The ecology of West African arid savannah snakes is still poorly known, especially in regard to the fossorial species. Here, field data on distribution, morphometrics, habitat use and diet are reported for the sand boa Eryx muelleri (Erycidae) from three different countries, i.e. Burkina Faso, Togo and Nigeria. This snake was observed in 21 di(...)

Background: This study investigated the prevalence, serotypes and antimicrobial sensitivity patterns of Salmonella
enterica in environment in Ouagadougou, Burkina Faso. A total of 476 samples, consisting of 36 samples of tap
water, 51 samples of well water, 87 samples of channel water, 44 samples of reservoir water, 238 samples of fish,

Population Structure in Natural Stands, Seed Germination and Seedling Growth of Sterculia setigera under Nursery Conditions in Burkina Faso (West Africa)
Philippe Bayen, Anne Mette Lykke, Amadé Ouédraogo, Adjima Thiombiano
The present study aimed at evaluating S. setigera population structure in natural stands and estimating the effect of pretreatment methods on seeds’ germination capacity and seedling establishment. Dendrometrical measurements were performed on 504 S. setigera trees for population structure assessment. The bell shaped structure obtained indicat(...)

Impact de l’artisanat minier sur les sols d’un environnement agricole aménagé au Burkina Faso
Ousmane BAMBA, Souleymane PELEDE, Aboubakar SAKO, Nicolas KAGAMBEGA Mariette Y. W. MININGOU
Au Burkina Faso, l’orpaillage contribue aux revenus des populations rurales. Cependant, cette activité utilise des technologies mal adaptées qui causent des impacts négatifs sur l'environnement et les ressources naturelles, en l’occurrence les sols. Dans un contexte du cours de l’or favorable, le nombre de mines artisanales s’est accru et il e(...)

Elephants or Excrement? Comparison of the Power of Two Survey Methods for Elephants in West African Savanna
Emmanuel M. Hema, R. F. W. Barnes, Wendengoudi Guenda
Statistical power is the key issue when evaluating wildlife trends. Wildlife managers in West Africa lack light aeroplanes and must often estimate wildlife trends on foot, either by counting the animals themselves or by counting their dung. We compared direct ground counts of elephants and dung counts in two consecutive years in Nazinga Game R(...)

Distribution of savannah elephants (Loxodonta africana africana Blumenbach 1797) within Nazinga game ranch, Southern Burkina Faso
Emmanuel M. Hema, R. F. W. Barnes, Wendengoudi Guenda
We tested the hypothesis that elephant distribution inside the Nazinga Game Ranch (Southern Burkina Faso) during the wet season is influenced by villages outside, while in the dry season elephants are restricted only by water. Occupancy was evaluated by recording elephant dung-piles on 54 line transects in each of three seasons: wet 2006, dry(...)

Rare earth and trace element geochemistry of termite mounds in central and northeastern Namibia: Mechanisms for micro-nutrient accumulation
Aboubakar Sako, Anthony J. Mills & Alakendra N. Roychoudhury
Rare earth element (REE) and trace element concentrations of ten termite mounds and adjacent topsoil from central and northeastern Namibia were used to investigate the processes underlying the alteration of soil chemical and physical properties by termites (Macrotermes spp.). Accumulation of micro-nutrients in the mounds was of particular inte(...)

The efficiency of meandering transects—in terms of accuracy, precision and effort required for estimating elephant abundance—was evaluated in the Kakum Conservation Area in Ghana. Four consecutive elephant dung surveys were carried out between February 2000 and February 2002 using meandering transects. The resulting dung density estimates were(...)

Adsorption and surface complexation modeling of palladium, rhodium and platinum in surficial semi-arid soils and sediment
Aboubakar Sako, Lidia Lopes & Alakendra N. Roychoudhury
Sorption isotherms, time-dependent adsorption and surface complexation modeling studies were used to investigate the post-depositional mobility of three of the platinum group-elements (Pd, Rh, and Pt) in semi-arid soil and sediment samples with varying surface properties. The acidity constants (Log Ka1 and Log Ka2), optimized from batch titrat(...)
