CCA analysis of the measured biometry and regeneration variables using as explicatory variables: plots inside the aggregated retention (AR), basal area (BA, m2 ha−1), crown and debris cover (CC, %), plots covered by debris (D), plots with dominance of dicot plants (DICO), diffuse radiation (DIFR, W m-2), direct radiation (DIRR, W m-2), distance to aggregate edge (DIST, m), plots located in the dispersed retention (DR), global radiation (GR, W m-2), leaf area index (LAI), plots with dominance of monocot plants (MONO), photosynthetically active radiation (PAR) above understory plants and debris (PAR-A) (μmol m−2 s−1), PAR below understory plants and debris (PAR-B) (μmol m−2 s−1), plots located in roads (R), plots located near a remnant tree in the dispersed retention (RT), and volumetric soil water content (VSW, %). Plots were classified according to the different treatments: a aggregated retention (white dots), dispersed retention (gray dots), near a remnant tree in the dispersed retention (black dots), roads (white square), under debris (gray square), under monocot plants (black square), and under dicot plants (white triangle); b stand 1 (white dots), stand 2 (gray dots), and stand 3 (black dots)
