Abstract

MENDEZ-TORIBIO, Moisés et al. Composition, structure and diversity of Tziritzícuaro tropical dry forest tree community, Balsas Watershed, Michoacán, Mexico. Rev. Mex. Biodiv. [online]. 2014, vol.85, n.4, pp.1117-1128. ISSN 2007-8706.  https://doi.org/10.7550/rmb.43457.

We characterized the composition, structure and diversity of tropical dry forest trees at Tziritzícuaro, municipality of La Huacana, in the Depresión del Balsas, Michoacán. We sampled all trees that were rooted inside 36 plots of 100 m² (0.36 ha) with a diameter at breast height (DBH) ≥ 1 cm. A total of 78 species, including 50 genera and 24 families were recorded. Fabaceae was the most important family respect to the number of species (24), genera (14) and individuals (274). It was recorded a total of 1 013 individuals and 2 313 stems. Basal area, cover and height average were of 0.18 m², 310 m² and 5 m, respectively. The average of species richness was of 10 species, with a mean value of Fisher α= 8. The tropical dry forest studied shares comparable characteristics to similar communities located in other parts of Mexico and the Neotropics, this enable to confirm patterns previously detected in the composition, structure and diversity of this vegetation type.

Keywords : trees; alpha diversity; Fabaceae; importance value.
