- Abstract: The influence exerted by tree communities, topography, and soil chemistry on the assembly of macrofungal communities remains poorly understood, especially in highly diverse tropical forests. Here, we used a large dataset that combines inventories of macrofungal Basidiomycetes fruiting bodies, tree species composition, and measurements for 16 soil physicochemical parameters, collected in 34 plots located in four sites of lowland rain forests in French Guiana. Plots were established on three different topographical conditions: hilltop, slope, and seasonally flooded soils. We found hyperdiverse Basidiomycetes communities, mainly comprising members of Agaricales and Polyporales. Phosphorus, clay contents, and base saturation in soils strongly varied across plots and shaped the richness and composition of tree communities. The latter composition explained 23% of the variation in the composition of macrofungal communities, probably through high heterogeneity of the litter chemistry and selective effects of biotic interactions. The high local heterogeneity of habitats influenced the distribution of both macrofungi and trees, as a result of diversed local soil hydromorphic conditions associated with contrasting soil chemistry. This first regional study across habitats of French Guiana forests revealed new niches for macrofungi, such as ectomycorrhizal ones, and illustrates how macrofungi inventories are still paramount to can be to understand the processes at work in theAbstract: The influence exerted by tree communities, topography, and soil chemistry on the assembly of macrofungal communities remains poorly understood, especially in highly diverse tropical forests.

RESUMO: L'influence exercée par les communautés d'arbres, la topographie et la chimie du sol sur l'assemblage des communautés de champignons reste très peu comprise, en particulier dans les forêts tropicales. Nous avons utilisé un jeu de données conséquent qui combine des inventaires de fructifications fongiques de Basidiomycètes, la composition en espèces d'arbres ainsi que les mesures de seize paramètres physico‐chimiques du sol, le tout collecté dans 34 parcelles de forêts tropicales situées dans 4 sites différents en Guyane Française. Les parcelles ont été établies dans trois conditions topographiques : en haut de colline, le long de la pente et dans les bas‐fonds inondés. Nous avons trouvé des communautés de Basidiomycètes très diverses, principalement appartenant aux Agaricales et Polyporales. Le phosphore, le contenu en argile et le taux de saturation sont extrêmement variables entre les parcelles et impactent la richesse et la composition des communautés d'arbres. Cette dernière explique 23% de la variation de la composition des communautés fongiques, probablement à travers la forte hétérogénéité de la chimie des litières et les effets sélectifs des interactions biotiques. L'hétérogénéité locale forte des habitats influencent la distribution à la fois des champignons et des arbres, conséquence de conditions hydromorphiques locales associées à une chimie contrastées des sols. Cette première étude régionales des habitats forestiers de Guyanes Française a révélé de nouvelles niches pour les macromycètes, telles que les ectomycorhizes, et souligne l'importance primordiale des inventaires afin de comprendre les processus au travail sous les tropiques … (more)
