| description | Background and Aims: The study of tropical forests is of great interest due to its high biodiversity related to the variability of the environment, which increases the diversity and specificity of its components. This study presents an evaluation of the structure, richness and diversity of woody angiosperms of the semideciduous forest (SMsC) in the center of the state of Veracruz, with the aim of contributing to their knowledge and to identify areas of high value for the conservation of the few fragments of primary vegetation that still exist in the area.Methods: Sixty-seven plots of 100 m2each were delineated, distributed in five study sites in the municipalities of Jalcomulco and Tlaltetela. In each plot, all individuals with DBH ≥5 cm were registered and measured and coverage, density, basal area and height were estimated, as well as the values of α diversity (total richness, richness per plot and α Fisher index), β diversity (similarity matrix with Jaccard and % similarity), and as the species ecological importance by the Curtis Relative Importance Value (RIV).Key results: Ninety-eight woody plant species were registered, grouped in 84 genera and 35 families of angiosperms. The most diverse families were Fabaceae and Euphorbiaceae. The predominant life form were trees (75.5%). This tropical forest shows a high richness and species turnover. The dominant species according to the RIV were Resinanthus aromaticus and Brosimum alicastrum, although the set of six dominant species varied greatly between the study sites.Conclusions: The presence of some key species such as Brosimum alicastrum, Resinanthus aromaticus and Sapranthus microcarpus allowed to identify the characteristic features of the semideciduous forest and its ecotones with the medium evergreen forest and the deciduous forest. |

Antecedentes y Objetivos: El estudio de las selvas tropicales es de gran interés debido a su alta biodiversidad, relacionada con la variabilidad del ambiente, que incrementa la diversidad y la especificidad de sus componentes. Este estudio presenta una evaluación de la estructura, riqueza y diversidad de especies de angiospermas leñosas de la selva mediana subcaducifolia (SMsC) en el centro de Veracruz, con el objetivo de contribuir al conocimiento de sus características e identificar áreas de alto valor para la conservación de los escasos fragmentos de vegetación primaria que aún existen en la zona.Métodos: Se delimitaron 67 parcelas de muestreo de 100 m2, distribuidas en cinco sitios de estudio en los municipios Jalcomulco y Tlaltetela. En cada parcela se registraron y midieron todos los individuos con DAP ≥5 cm y se estimaron sus valores de cobertura, densidad, área basal y altura, así como los valores de diversidad α (riqueza total, riqueza por parcela e índice α de Fisher) y los valores de diversidad β (matriz de similitud con coeficiente de Jaccard y porcentaje de similitud), además de la importancia ecológica de las especies mediante el Valor de Importancia Relativa de Curtis (VIR).Resultados clave: Se registraron 98 especies de plantas leñosas, agrupadas en 83 géneros y 35 familias de angiospermas. Las familias más diversas fueron Fabaceae y Euphorbiaceae. La forma biológica predominante (75.5%) fueron los árboles. La selva tropical mostró una alta riqueza y elevada tasa de recambio de especies. Las especies dominantes de acuerdo con el VIR fueron Resinanthus aromaticus y Brosimum alicastrum, aunque el conjunto de las seis especies dominantes fue muy variable entre los sitios de estudio.Conclusiones: La presencia de especies clave como Brosimum alicastrum, Resinanthus aromaticus y Sapranthus microcarpus permitió identificar los elementos característicos de la SMsC y sus ecotonos con la selva mediana subperennifolia y la selva baja caducifolia.
