| ABSTRACT We compared the reproductive phenology and floral visitors of Eschweilera tetrapetala growing along the edge and in the interior of a submontane forest in the Chapada Diamantina mountains, Bahia State, Brazil. We sought to determine if there were inter-annual differences in intensity and seasonality associated with environmental conditions, and if there were differences in floral visitors between the two environmental contexts. Phenological observations were performed for three years, and included the occurrence of an El Niño event. We applied circular statistics to detect seasonal trends, performed cross correlations between phenophases and climate, Kruskal-Wallis and Wilcoxon signed-rank tests for inter-annual variation, and the... |

| This study aims to detect the composition, abundance patterns, and successional stage distributions exhibited by arboreal species inside and at the linear edge of a submontane seasonal forest in the Chapada Diamantina (12°28'31'S, 41°23'14'W), Bahia, Brazil. The individual plants with breast height diameters ≥5 cm were sampled in 30 quadrats (10 m × 10 m), 15 in the forest edge and 15 inside the forest. Species were classified according to successional category. Phytosociological and diversity indices were calculated. Shannon indices were compared using Hutcheson's t-test, and the remaining parameters were analyzed by ANOVA. Linear edges exerted a high impact on the floristic composition, diversity, and abundance of species, though little interference was... |
