Population structure of three woody species in four ethnic domains of the sub‐sahel of Burkina Faso
T. K. Sop, J. Oldeland, U. Schmiedel, I. Ouedraogo, A. Thiombiano
In developing countries many people depend on woody resources for their livelihoods. Monitoring human impact on the populations of socio-economically important species is therefore important for the conservation of vulnerable plants.
In order to assess and compare the population structure and regeneration patterns of three multipurpose spec(...)

The Ironical Figure of Reuben Bourne in NathanielHawthorne’s “Roger Malvin’s Burial”
PODA Michel
The figure of Reuben Bourne in “Roger Malvin’s Burial” by
Nathaniel Hawthorne is quite striking. Appearing as the fictional duplicate of
a classical knight hero, endowed with bravery, self-denial and sense of
honour, he falls short of the reader’s expectations in the course of events. He
is but a wounded hero, whose real capacity cannot ma(...)

Approche participative et gouvernance locale des ressources forestières dans la forêt classée de Tuy : atouts et contraintes
DIPAMA Jean-Marie
Partout en Afrique sahélienne, le souci de préserver la biodiversité dans certains écosystèmes avait amené les pouvoirs publics à prendre en charge la gestion des ressources naturelles dont les forêts classées. Mais, pour des raisons diverses, ces enclaves subissent d’énormes préjudices suite à une exploitation de plus en plus accrue, souvent(...)

Effects of various cooking methods and food components on bioaccessibility of mercury from fish
Ousséni Ouédraogo, Marc Amyot
Fish consumption is the main source of human exposure to mercury. Studies from specific human populations have reported Hg levels lower than those modeled from consumption data These discrepancies between expected and measured Hg levels may be explained by differences in dietary habits such as cooking methods and food components on fish Hg bio(...)

Phenolic compounds and antioxidant activities in some fruits and vegetables from Burkina Faso
Romaric G. Bayili , Fatoumata Abdoul-Latif , Oumou H. Kone , Mamounata Diao , Imael H. N. Bassole and Mamoudou H. Dicko
Levels of total phenolic compounds (TPC), proanthocyanidins (PAs) and antioxidant activities among sixteen fruits and vegetables commonly consumed in Burkina Faso were determined. Levels of TPC ranged from 0.21 to 3.33 mg of gallic acid equivalent per gram of fresh matter. The highest contents in TPC were found in hot chi(...)
