Appendix S2: Dataset codes. The data are stored in Appendix S1 and consist of 15 variables. Here, we explain what each header in the dataset signifies. record A number assigned to each line (record) of the data file. species The name of the species studied. We studied 11 different species: Cordia alliodora, Cordia stenoclada, Ficus obtusifolia, Ficus tecolutensis, Cupania glabra, Ficus trigonata, Lonchocarpus schiedeanus, Coccoloba hondurensis, Pouteria squamosa, Spondias radlkoferi,Trichilia havanensis. collection Collection number ind A code assigned to each individual (tree). level A numerical code that indicates the order of ramification of the measured stem: 1 for trunks and values greater than 1 for branches. circumf_cm Circumference of the stem, in centimeters diam_cm The diameter of the stem, in centimeters. diam_m The diameter of the stem, in meters. crown_area_m The two-dimensional area of the polygon described by the foliage presented to the sky by a given stem, in square meters. species2 A code assigned to each species: Cordia alliodora: 3, Cordia stenoclada: 4, Ficus obtusifolia: 5, Ficus tecolutensis: 6, Cupania glabra: 1, Ficus trigonata: 7, Lonchocarpus schiedeanus: 8, Coccoloba hondurensis: 2, Pouteria squamosa: 9, Spondias radlkoferi: 10,Trichilia havanensis: 11. numind Number of sampled individuals from each species. trunk A binary variable that indicates whether the stem was a trunk (1) or a branch (0). Young Young¬¥s modulus, constant within species. salt A binary variable that indicates whether trees were pruned by salt breezes: yes (1), no (0). paraglider A binary variable that indicates which method was used to measure the crown area: 1 if an aerial photograph was taken from a powered paraglider and 0 if traditional ground-based methods were used. The size of the leaves of each species is given by the variable ’Äúleaf’Äù defined in the R program in Appendix S3.
