| description | Due to the fact that tree size can significantly influence community structure, and thus diversity, structural diversity indices which incorporate DBH and total tree height can be more accurate estimators than the classic diversity indices. The structural diversity of a tropical humid forest (THF) and a tropical sub-humid forest (TSF), in Tabasco, Mexico, was compared using eight structural indexes that estimate community basal area sorted by DBH and tree height classes. The species, DBH and total tree height of trees > 10 cm DBH were determined. The structural indices were statistically compared between the two communities. The TSF presented 27 species, 211 trees and 129 palms ha-1, a mean DBH of 28.0 cm and 9 trees > 20 m height. The THF presented 66 species and 591 trees ha-1, a mean DBH of 21.2 cm and 36 trees > 20 m height. The structural indices of the THF (2.76 – 6.737) were significantly higher than those of the TSF (2.345 – 4.978). The Gini indices of the THF (0.61 and 0.494) indicated that trees were more heterogeneous in size (diameter and height) than those of the TSF (0.583 and 0.419). The structural indices therefore evaluate species diversity and community structural diversity in a more complete way, with the THF presenting higher structural diversity than TSF, which suggests the value of their use within tree vegetation studies. |

Debido a que el tamaño de los árboles puede influir significativamente en la estructura de una comunidad y consecuentemente en su diversidad, los índices de diversidad estructural constituyen estimadores más precisos que los índices de diversidad clásicos ya que incorporan el diámetro y altura de los árboles. Mediante el uso de ocho índices estructurales, considerando el área basal de la comunidad por clases de diámetro y altura de los árboles, se comparó la diversidad estructural de una selva alta perennifolia y una mediana subperennifolia en Tabasco, México. Para los árboles con diámetro a la altura del pecho mayor a 10 cm, se determinó especie, diámetro a la altura del pecho y altura total, y los índices se compararon estadísticamente entre las dos comunidades. La selva mediana subperennifolia presentó 27 especies, 211 árboles y 129 palmas por hectárea, diámetro promedio a la altura del pecho de 28.0 cm y 9 individuos > 20 m de altura. La selva alta perennifolia tuvo 66 especies y 591 árboles por hectárea, diámetro promedio a la altura del pecho de 21.2 cm y 36 árboles > 20 m de altura. Los índices de diversidad estructural de la selva alta perennifolia (2.76 – 6.737) fueron significativamente (p<0.01) mayores que los de la mediana subperennifolia (2.345 – 4.978). Los índices (Gini) de la selva alta perennifolia (0.61 y 0.494) indicaron que los árboles son más variables en su tamaño (diámetro y altura) que los de la mediana subperennifolia (0.583 y 0.419). Se concluye que los índices de diversidad estructural reflejan tanto la diversidad de especies como la complejidad estructural de la comunidad, siendo más diversa la selva alta perennifolia que la mediana subperennifolia. Se sugiere su uso para las comunidades arboladas.
