Autocorrelogram of CAI values for each study area: mean Moran's <i>I</i> computed for 12 to 14 distance intervals.

<p>On the left side (<1 m), the abscissa for the two first symbols represent the vertical distance between soil layers from a same pit, the left and right symbols distinguishing adjacent layers from non-adjacent layers, respectively. On the right side (>10 m), the abscissa corresponds to horizontal distance between soil volumes from different pits located in a same plot (first symbol between 10 m and 100 m), different plots of a same site (between 100 m and 5000 m) or different sites (>5000 m). Full symbols indicate significantly positive or negative Moran's <i>I</i> value (<i>P</i><0.05).</p

Data_OuedraogoEtAl2017_Biotropica

We provide a zip file containing three txt files and one R script file used in the analyses presented in the article assessing the size at reproduction of 31 major timber species in central Africa. The ReproductiveSize_DATA.txt file contains the list of trees monitored for reproductive phenology in three central African countries (Cameroon, Congo, and Central African Republic) in 11 sites, with their species names, diameter, crown exposure index, and phenological status. The ReproductiveSize_TRAITS.txt file contains the list of the 31 studied species with their traits (regeneration guild, leaf habit, wood density, maximum diameter and height, dispersal mode, and maximum growth rate). The ReproductiveSize_MCDL.txt file contains the list of the 31 studied species with their minimum cutting diameter limits in the three studied contries. The ReproductiveSize_SCRIPT.r file contains the code used to perform the analyses and make the figures

Cluster dendrogram grouping species with similar distribution patterns.

<p>A hierarchical cluster analysis on the Euclidean distances between species scores and an average agglomeration method was used to identify groups of species according to their distribution patterns, i.e. position across the compositional axes. The grey boxes indicate the cut-off level used to identify the four groups.</p
