Abstract |
Fungi from tropical regions are currently under-represented in the classification system. Indeed, difficult access to tropical forests and irregular occurrence carpophores make it complicated to study fungus species in such environments, unlike in European zones where fungal diversity and taxonomy are better known. The purpose of this work was to enhance classification by integrating new data that would bring out the importance of certain traits of these fungi, and provide a clearer understanding of how the biodiversity of fungi from the forest ecosystems of French Guiana is organized, particularly those causing wood decay through white rot, brown rot or soft rot. In our study, we chose to work in the zone comprising the internal transcribed spacers ITS1 and ITS2, which are relatively variable, and the 5.8 S small ribosomal subunit, which is not highly variable. The primers ITS 1(5’-TCCGTAGGTGAACCTGCGC-3’) and ITS 4 (5’-TCCTCCGCTTATTGATATGC-3’), specific to fungi, were chosen for this taxonomic analysis of the studied species. This study was carried out on 101 fungus fruiting bodies at the Paracou forest site in French Guiana. Of those 101 fungi, 72 were identified by BLASTn. Four species were Ascomycetes of the genus Muscodor and Xylaria. The other 68 species, all in the class of the Basidiomycetes, were divided into the following orders: 31 Agaricales, 1 Atheliales, 2 Boletales, 1 Gomphales, 12 Polyporales, 1 Trechisporales and 1 Tremellales. There was also an indeterminate taxon very similar to the lichens. Within the order Polyporales, the main genera were found, such as Antrodiella, Coriolopsis, Fomitopsis, Ganoderma, Lentinus, Pycnoporus, Steccherinum, Trametes, Fomitoporia. All these fungi have the particularity of causing wood decay. |

Abstract |
Cet article se propose d’analyser les stratégies mises en œuvre en France et au Brésil vis-à-vis de la production et de la diffusion de données de suivi de pressions anthropiques sur les écosystèmes amazoniens, à savoir les impacts de l’orpaillage en Guyane française et du développement agricole au Brésil. On montre qu’indépendamment de la législation en vigueur, les stratégies mises en œuvre par les États sont très différentes et que cela influe de façon déterminante sur les positionnements et revendications de la société civile vis-à-vis de ces données. Au cours de la dernière décennie, le Brésil tend vers une ouverture croissante de l’accès aux données concernant la déforestation, poussé à la transparence par la contre-expertise d’ONG nationales et par la pression internationale. En Guyane, on constate au contraire un mouvement de fermeture des données concernant le suivi des impacts de l’orpaillage, lié à une implication croissante des services d’État en charge de la sécurité nationale dans le processus de suivi. |

Abstract |
The reproductive ecology of two species of Dieffenbachia (D. seguine [Jacq.] Schott and D. paludicola N.E. Br. ex Gleason) was studied at the Nouragues field station research in French Guiana. As in other known Dieffenbachia, the two studied species presented the classical cyclocephaline (dynastine scarab beetle) pollination system: Nocturnal anthesis with a strong odor, protogynous and short anthesis over 2 (3) days, female flowers being receptive on the first night and pollen being released on the second night. Inflorescences of D. seguine were visited by two species of scarab beetles (Cyclocephalini, Dynastinae): the dark brown Cyclocephala rustica and the black Erioscelis proba; while Inflorescences of D. paludicola were only visited by Erioscelis proba. Scarab beetles were efficient pollinators resulting in a high reproductive success even if some self-pollination can occur. Original data were gathered on flower and fruit predation leading to pollen and seed loss but their effect of the reproductive success still needs to be quantified. |
