“…The generality of the bat-pollination syndrome is shown by the readiness with which pteropodids visit, and in some cases pollinate, Neotropical bat plants grown as ornamentals, and with which Neotropical phyllostomids visit Oriental bat plants (Marshall, 1985). The pantropical genus Parkia is pollinated in a very similar way by unrelated bats in the Old and New World (Hopkins, 1994).…”

Current knowledge of flower visitors and pollination in the Oriental Region is summarised. Much less is known about pollination than seed dispersal and the coverage of habitats and taxa in the region is very uneven. The available evidence suggests that pollination in lowland forests is dominated by highly social bees (mainly Trigona and Apis species), with beetles probably the next most important group, followed by other bees and flies. In comparison with the better-studied Neotropics, large solitary bees, moths, Lepidoptera and vertebrates are relatively less important. These differences are greatest in the canopy of the lowland dipterocarp forests of Southeast Asia, where they probably reflect the unique temporal pattern of floral resource availability resulting from 'general flowering' at supra-annual intervals. Apis bees (but not Trigona species) are also important in most montane, subtropical and non-forest habitats. Apart from the figs (Ficus spp.), there are few well-documented examples of plant species visited by a single potential pollinator and most plant-pollinator relationships in the region appear to be relatively generalised. The small sizes of most pollinators and the absence of direct human exploitation probably make pollination mutualisms less vulnerable to failure as a result of human impacts than dispersal mutualisms, but more subtle impacts, as a result of altered gene flows, are likely to be widespread. On current evidence, pollination systems in the Oriental Region do not require any specific conservation action, but this review reinforces arguments for making the preservation (or restoration) of habitat connectivity the major focus of Oriental conservation.

Toutes espkces confondues, la pCriodicitC est annuelle et nettement saisonnikre. Elle n'est pas corrClCe aux variations pluviomCtriques et, en particulier, elle n'est pas li6e i l'existence d'une saison skche. Elle semble plus nettement like aux variations photopCriodiques, bien que celles-ci soient de faible amplitude (35 min ii 5'30' de latitude nord). Toutefois, chaque arbre se dtfeuille selon une periodicit6 qui lui est propre. I1 existe donc un paradoxe entre la saisonnalitC de la dCfeuillaison et son caractkre individuel.

The FrenchGuianan forest is an evergreen rain forest that contains approximately 100 deciduous tree species. The taxonomical distribution of the deciduous character is widely spread, and its presence or absence among some taxa, as well as its ancient origin, are arguments in favour of an endogenous origin. Leaf-fall periodicity was studied on a sample of 500 trees during a 2-year period. Periodicity is annual and seasonal. It is not correlated to rainfall and not linked to the occurrence of a dry season. It seems closely correlated to photoperiodical variations, even though those variations are weak (35 min at latitude 5'30'N). However, each tree has its own periodicity for leaves shedding. Therefore, there is a paradox between seasonality and individual periodicity of leaf fall. The existence of this paradox leads us to consider the hypothesis of an integration of endogenous and exogenous components in the determination of leaf-fall periodicity.

“…Parkia is a pantropical genus of the family Fabaceae (Aubréville, 1950 ;Arbonnier, 2002) which includes 34 species distributed in South America (18 species), Asia (12 species) and Africa (4 species including one in Madagascar) (Hopkins, 1986 ;Luckow and Hopkins, 1995 ;Luckow, 2005). P. biglobosa is a species of this genus and is commonly used in medicine and traditional pharmacopoeia (Ouédraogo, 1995).…”

Parkia biglobosa is a medicinal plant that is used in the traditional treatment of various pathologies. The fermented seeds of this plant « néré » are used commonly in the treatment of high blood pressure. In order to establish the safety of these, acute and subacute toxicity tests were performed. For this purpose, hematological and biochemical parameters were determined in rats after repeated dosing of 1000, 2000, 3000, 4000 and 5000 mg/kg body weight (bw) of the aqueous and ethanolic extracts of the fermented seeds of P. biglobosa for 28 days. The resulting LD 50 is greater than 5000 mg/kg bw and the extracts have no effect on most of the measured blood parameters. This study revealed that extracts of the fermented seeds of Parkia biglobosa are non-toxic at all doses tested and have immunostimulant and analgesic activity.
