I will provide a short and selective overview of models of species coexistence. I will also present two new models, a spatially structured model of species abundances, and a spatially implicit model predicting both the abundances of species and their phylogenetic relatedness. I will show how the parameters of these models can be inferred based on field data. I will then present our first attempts to assemble a dataset designed to the validation of such models in species-rich tropical forest tree communities of French Guiana. My emphasis will be on designing a proper field strategy in a tropical forest project, and I will show some of our early and exciting results combining tools in plant physiology, molecular biology, and modelling. Finally I will discuss how existing models of biodiversity can benefit from such databases.
