03/02/2022 de 11h00 à 12h00PS 2 salle 201

GuyaDiv is a network of forest plots installed over the whole territory of French Guiana, where trees over 10 cm DBH are identified. We use its information (1507 species censused in 68 one-hectare plots) to estimate the exponent of the species-area relationship, assuming Arrhenius’s power law. We can then extrapolate the number of species from a local, wide inventory (62.5 ha in Paracou research station). Then, the number of tree species is estimated over the territory.
