Approche historique de l'expansion des pêcheurs ghanéens Fante et Ewe sur le littoral ivoirien IRD
Delaunay, K..
Small-scale marine fisheries in the Côte d'Ivoire are at present in the hands of Ghanaian fishermen (Fante and Ewe tribes), who have a long-established tradition as seafarerers. in order to understand this situation, we have examined the historical processes leading to this Ghanaian "dynamism". Study of the timing of the expansionist movement of Ghanaian fishermen shows that the Fante and Ewe have developed different strategies, which help explain the logic of the phenomena of permanent settlement and technological change. The historical approach leads to a study of social relationships. (Résumé d'auteur)

Chronique d'une culture conquérante : le taro (Tchad méridional et Nord-Cameroun) IRD
Seignobos, Christian.
Un Colocasia se diffuse actuellement, à parir du Nigéria, dans les régions du Tchad et du Nord-Cameroun. Le suivi de ce tubercule laisse apparaître un certain nombre de mécanismes, tant pour les acteurs de la diffusion que pour les groupes qui développent sa culture. Il permet à la fois d'exhumer le rôle des taros "archaïques" dans d'anciens agrosystèmes et de mieux percevoir certaines stratégies villageoises actuelles. Cette diffusion spontanée demanderait en outre à être prise en compte par les développeurs à l'écoute des besoins de sociétés villageoises. (Résumé d'auteur)

Control of leaf growth by abscisic acid: hydraulic or non-hydraulic processes Inra
Tardieu, F.; Parent, B.; Simonneau, T..
Abscisic acid (ABA) affects plant metabolism and water transfers via multiple mechanisms at cell, organ and whole plant levels. These mechanisms translate into contradictory effects on leaf growth, so the literature reports positive, null or negative effects of ABA on leaf growth upon water deficit. We review evidences based on genetic manipulations of ABA biosynthesis, feeding the plant with artificial ABA or partial root drying and provide elements to avoid confusions of effects. We propose that ABA has mainly three effects on growth. (i) Via its controlling effect on stomatal aperture and transpiration rate, an increased concentration of ABA tends to buffer the day-night alternations of leaf growth rate and the negative effect of evaporative demand....

Cultural contacts between Micronesia and Melanesia IRD
Intoh, M..
Les îles Carolines en Micronésie et les îles du nord de la Mélanésie ont partagé pendant la préhistoire plusieurs traits culturels, parmi lesquels les langues, les herminettes en térèbre (#Terebra$ sp.), les leurres en nacre, le tissage, la pêche au cerf-volant, etc. L'étude de la répartition des herminettes en térèbre en Micronésie a montré que cet outil unique apparaît relativement tard dans la chronologie préhistorique micronésienne, après l'an 1000 de notre ère. Cet objet semble avoir été en usage simultanément en Micronésie et en Mélanésie sans que l'on puisse dire si l'origine est micronésienne ou mélanésienne. Les enclaves polynésiennes en Mélanésie ne semblent pas étrangères à cette introduction. Les autres traits culturels partagés montrent qu'il...

Diel time-courses of leaf growth in monocot and dicot species: endogenous rhythms and temperature effects Inra
Poiré, R.; Wiese-Klinkenberg, A.; Parent, B.; Mielewczik, M.; Schurr, U.; Tardieu, F.; Walter, A..
Diel (24 h) leaf growth patterns were differently affected by temperature variations and the circadian clock in several plant species. In the monocotyledon Zea mays, leaf elongation rate closely followed changes in temperature. In the dicotyledons Nicotiana tabacum, Ricinus communis, and Flaveria bidentis, the effect of temperature regimes was less obvious and leaf growth exhibited a clear circadian oscillation.These differences were related neither to primary metabolism nor to altered carbohydrate availability for growth. The effect of endogenous rhythms on leaf growth was analysed under continuous light in Arabidopsis thaliana, Ricinus communis, Zea mays, and Oryza sativa. No rythmic growth was observed under continuous light in the two monocotyledons,...

Effects of agricultural practices on spatial dispersal patterns of four permanent grassland species Inra
Amiaud, B.; Merlin, A.; Damour, A.; Gaujour, E.; Plantureux, S..
The effects of agricultural practices on floristic composition of grasslands are well known but few studies investigated these effects on plant spatial patterns involved in the maintenance of plant diversity. In order to identify major processes controlling dispersal patterns of four grassland species, presenting several dispersion modalities (anemochorous, barochorous and zoochorous sensu Grime et al., 1988), we have used spatial analysis (4TLQV and Wavelet)adapted to grids sampling. With these methods, when the quadrat variances are plotted against block size, the peaks of these graphs are interpreted as the scale of the mapped phenomena (Guo and Kelly, 2004). A generalization of mowing impact according to dispersal modalities was highlighted by our...

Grands commerçants d'Afrique de l'Ouest : logiques et pratiques d'un groupe d'hommes d'affaires contemporains IRD
Grégoire, Emmanuel (ed.); Labazée, Pascal (ed.); Amselle, J.L. (pref.).
L'image de la "Nana Benz" togolaise, brassant des milliards de francs CFA que lui a rapportés son commerce de pagnes florissant, est bien connue. Celle du grand commerçant d'Afrique de l'Ouest, en grand boubou, ou en costume trois pièces, l'est tout autant. Ces images toutes sensationnelles qu'elles soient rappellent qu'en Afrique, l'initiative privée connaît ses réussites. Elle a ses traditions et surtout un bel avenir. Les auteurs de cet ouvrage, qui porte sur les réseaux marchands d'Afrique de l'Ouest, en décrivent les rouages et le fonctionnement.Ils montrent que, loin de constituer des survivances d'économies anciennes, ces réseaux sont au contraire des structures dynamiques, imaginatives, jouant à la fois des opportunités offertes par l'économie...
