Figure 1: Geographical location, pluviometry, and design of reciprocal transplantation experimental sites. a) Location of French Guiana along the north of South America; b) Greyscale map of pluviometry across French Guiana and location of the two plantation sites (Laussat and Régina). Average rainfall: Laussat (2500mm/year), Régina (3500mm/year) (reproduced from Brousseau et al ., 2015 with permission). c) Design of the reciprocal transplantation experiment. The black sigmoid curves represent the edaphic difference between HT and SF; The details on cartoon trees represent the different morphologies found in Symphonia associated with the HT and SF (i.e. S. sp1 in HT and S. globulifera in SF); solid lines represent juveniles planted in the same habitats and region as their provenance. Dashed lines represent transplants between habitat within regions. Dotted lines represent transplants between regions within habitats. Dotdashed lines represent transplants across regions and habitats.
