Population dynamics of medium and large mammals in a West African gallery forest area and the potential effects of poaching
Emmanuel M. Hema, Yaya Ouattara, Mamadou Karama, Fabio Petrozzi, Massimiliano Di Vittorio, Wendengoudi Guenda, Luca Luiselli
Few studies are available on the population dynamics of medium and large mammals in gallery forests of the Sudan and Sahel regions of West Africa. Line-transect studies of the abundance (estimated by KIA) of nine species of ungulates and three species of primates were carried out between 2004 and 2013 in the Comoé-Leraba protected area of Bur(...)

Detection of interannual population trends in seven herbivores from a West African savannah: a comparison between dung counts and direct counts of individuals
Emmanuel M. Hema, Massimiliano Di Vittorio, R. F. W. Barnes, Wendengoudi Guenda, Luca Luiselli
Abstract In West Africa, whether in forests or savannahs, most of the large mammal species have a scattered spatial distribution. Monitoring their population size represents a logistic, financial, theoretical challenge because counting of transects is not appropriate, unlike elsewhere in Africa. In this study, we (i) analyse the patterns of in(...)

Effets du pâturage sur la biomasse herbacée et sur des paramètres chimiques et biologiques des sols dans une savane arbustive au Burkina Faso
Lambiénou Yé, Jean‐Christophe Lata, Dominique Massé, Hassan Bismarck Nacro, Sébastien Barot
Cette etude a porte sur les sols et la vegetation herbacee d’une savane pâturee au Burkina Faso. Elle decrit les effets du pâturage sur la biomasse herbacee et sur les parametres chimiques et biologiques des sols. Pour ce faire, des couples de parcelles (protegees et non protegees du pâturage) ont ete installes dans les facies des quatre espec(...)

Bushmeat consumption in the West African Sahel of Burkina Faso, and the decline of some consumed species
Emmanuel M. Hema, Valy Ouattara, Gnoumou Parfait, Massimiliano Di Vittorio, Djidama Sirima, Daniele Dendi, Wendengoudi Guenda, Fabio Petrozzi, Luca Luiselli
Abstract To explore the patterns of bushmeat trade in the Sahel we carried out a multidisciplinary study, focusing on Burkina Faso. We conducted baseline interview surveys to examine the variation in people's perceptions of bushmeat in relation to their place of residence (urban vs rural), sex and age. We also analysed the long-term (1985–2010(...)

First assessment of age and sex structures of elephants by using dung size analysis in a West African savannah
Emmanuel M. Hema, Massimiliano Di Vittorio, Fabio Petrozzi, Luca Luiselli, Wendengoudi Guenda
Abstract 1. An age and sex structure study of the West African savannah elephant (Loxodonta africana africana) population of the Nazinga Game ranch (Burkina Faso) was carried out using direct sightings of individuals near water points, where they group during hot periods of the day, and droppings circumference measurements of dung pile along l(...)

The green economics of conventional, organic and genetically modified crops farming: a review
Yirviel Janvier Métouolé Méda, Irene Susana Egyir, John Baptist Donsaananang Jatoe, Calvin Atewamba and Pam Zahonogo
There are many controversies about the relative performances of conventional farming (CF), organic farming (OF) and genetically modified crops farming (GMCF) technologies. This paper aimed to identify the overall best technology by reviewing the performances of CF, OF and GMCF from a green economics perspective. Existing literature could not a(...)

Contrasted effects of annual and perennial grasses on soil chemical and biological characteristics of a grazed Sudanian savanna
Lambiénou Yé, Jean Christophe Lata, Dominique Masse, Hassan Bismarck Nacro, Roger Kissou, Ndèye Hélène Diallo, Sébastien Barot
Growth and composition of plant communities depends on physico-chemical and biological characteristics of soils. Conversely, plants influence nutrient cycling and soil characteristics. Thus, they affect the long-term availability of nutrients, which feedbacks on their own growth and the primary productivity of ecosystems. This study focuses on(...)

Exploring the main threats to the threatened African spurred tortoiseCentrochelys sulcatain the West African Sahel
Fabio Petrozzi, Edem A. Eniang, Godfrey C. Akani, Nioking Amadi, Emmanuel M. Hema, Tomas Diagne, Gabriel Hoinsoudé Segniagbeto, Laurent Chirio, Giovanni Amori, Luca Luiselli
Abstract The African spurred tortoiseCentrochelys sulcatais the second largest terrestrial turtle, with a scattered distribution across the West African Sahel. This species is threatened and declining consistently throughout its range, but little is known about the causes of its decline. It has been hypothesized that the decline is attributabl(...)

Selective disturbance by elephants ( Loxodonta africana ) on eight tree species in a West African savannah
Emmanuel M. Hema, R. F. W. Barnes, Massimiliano Di Vittorio, Luca Luiselli, Wendengoudi Guenda
Abstract African elephants ( Loxodonta africana ) are ecosystem engineers in African savannahs, but their role in the modifications of the populations of trees by means of their browsing activities has been poorly studied so far in West Africa. We studied the disturbance of elephants to eight selected species of trees in the Nazinga Game Ranch(...)

Dispersal of Egyptian VulturesNeophron percnopterus:the first case of long-distance relocation of an individual from France to Sicily
Massimiliano Di Vittorio, Sylvain Henriquet, Erick Kobierzycki, Luca Luiselli, Emmanuel M. Hema, Loredana Murabito, Giuseppe Rannisi, Pascual López‐López
Knowledge of juvenile dispersal is important for understanding population dynamics and for effective conservation, particularly of geographically isolated raptor populations. Here, we report the first documented case of a long-distance movement of an Egyptian Vulture Neophron percnopterus from the French population to Sicily. This observation(...)

Ecosystem services must tackle anthropized ecosystems and ecological engineering
Sébastien Barot, Lambiénou Yé, Luc Abbadie, Manuel Blouin, Nathalie Frascaria‐Lacoste
The notion of ecosystem service is meant to better link human societies to ecological systems and to
serve has a tool for decision making. However, the notion has never been applied in a comprehensive
and consistent way to anthropized ecosystems while most ecosystems are indeed anthropized. This
means that in initiatives of ecosystem servic(...)

Hydrogeochemical processes controlling groundwater quality around Bomboré gold mineralized zone, Central Burkina Faso
Aboubakar Sako, Ousmane Bamba and Aridjima Gordio
This study investigates the processes that control dug well and borewell water chemistry in crystalline basement aquifers in semi-arid environment. Changes in SO4 2− and NO3 −were observed in both dugwell and borewell samples. Six dug wells and seven borewells had high NO3− concentrations relative to SO4 2− suggesting prevailing oxidizing redo(...)

Cowpea (Vigna unguiculata (L.) Walp.) is a grain legume crop cultivated in all the
agro-ecological zones of Burkina Faso. It plays an important role in human
nutrition due to its richness in protein and it enormous agronomic, sanitary and
economic potentialities. However, several virus originated diseases negatively
affect it production, t(...)
