Guyadiv is a network of permanent forest plots installed in French Guiana. The site Piton de l'Armontabo is composed of one 1ha-plot. A complete inventory of this plot has been made in 2006 : 538 trees with dbh>=10cm have been registrated and 533 species have been identified. 99,1% of the registrated trees have been identified to the species level. We only have the point coordinates and not the precise demarcation of the sample plot. In…

The UMR EcoFoG possesses an herbarium reference collection based on samples harvested all along the different forest plots studied by our teams.

A Excel database is linked to this collection and the taxa found in it are listed in the Guyafor database. The collection gathers more than 3000 samples representing 74 families, 288 genera and…

Geographical distribution of three nuclear clusters (Q1, Q2, Q3) inferred by a Bayesian clustering analysis (STRUCTURE) after evaluating genetic diversity at nine nuSSR over 217 Jacaranda copaia in five regions in the Neotropics (Western Amazonia, Southern Amazonia, Central Amazonia, Guiana Shield, Central America). For more details, see Scotti-Saintagne et al., 2013 Journal of biogeography vol 40 pp 707-719. This work was funded by the…
