Structure and composition of associated communities of pine-izote (Pinus pseudostrobus-Nolina parviflora) from Puebla, Mexico
The analysis of the structure and flora of the plant communities allows knowing the interrelations of the community with the environment. In Puebla, Mexico, there are plant communities composed of pine and izotal that suggest the following question: What is the similarity or floristic difference between both types of vegetation found in nearby areas? The objective was to analyze the richness, diversity, and floristic similarity in the pine forest and izotal to contribute to the knowledge of the diversity of this type of plant communities. Sampling units (SU) of 1000 m2, 16 m2, and 1 m2 were established for the high, medium, and low strata, respectively. Species were recorded, and density, dominance, and frequency were estimated to calculate the Importance Value Index. Diversity was calculated with the Shannon-Wiener index and the true diversity indexes. Cluster analysis was applied to assess floristic similarity and the species-SU association through ordination Bray-Curtis index. The floristic richness in the pine forest was 79 species and 86 in the izotal; the Shannon indices were 1.47 and 1.34, respectively and these indices were significantly different; the true diversity indices were 4.34 and 3.81, respectively. Both communities share 53 species, and they have a floristic similarity of 49 %. Pine forest and izotal showed significant differences in the density and coverage of species. This study contributes to the understanding of the structure and exchange of species in the flora of communities in dry areas of Mexico.

The analysis of the structure and flora of the plant communities allows knowing the interrelations of the community with the environment. In Puebla, Mexico, there are plant communities composed of pine and izotal that suggest the following question: What is the similarity or floristic difference between both types of vegetation found in nearby areas? The objective was to analyze the richness, diversity, and floristic similarity in the pine forest and izotal to contribute to the knowledge of the diversity of this type of plant communities. Sampling units (SU) of 1000 m2, 16 m2, and 1 m2 were established for the high, medium, and low strata, respectively. Species were recorded, and density, dominance, and frequency were estimated to calculate the Importance Value Index. Diversity was calculated with the Shannon-Wiener index and the true diversity indexes. Cluster analysis was applied to assess floristic similarity and the species-SU association through ordination Bray-Curtis index. The floristic richness in the pine forest was 79 species and 86 in the izotal; the Shannon indices were 1.47 and 1.34, respectively and these indices were significantly different; the true diversity indices were 4.34 and 3.81, respectively. Both communities share 53 species, and they have a floristic similarity of 49 %. Pine forest and izotal showed significant differences in the density and coverage of species. This study contributes to the understanding of the structure and exchange of species in the flora of communities in dry areas of Mexico. |

El análisis de la estructura y flora de las comunidades vegetales permite conocer las interrelaciones de la comunidad con su entorno. En Puebla, México, existen comunidades vegetales compuestas de pino e izotal, por lo que surge la pregunta ¿Cuál es la similitud o diferencia florística entre ambos tipos de vegetación que se encuentran en áreas cercanas? El objetivo fue analizar la estructura de la vegetación con base en la riqueza y semejanza florística en el pinar e izotal para contribuir al conocimiento de la diversidad de este tipo de comunidades vegetales. Se establecieron unidades de muestreo (UM) de 1000 m2, 16 m2 y 1 m2 para el estrato alto, medio y bajo respectivamente. Se registraron las especies y se estimó la densidad, dominancia y frecuencia, para calcular el Índice de Valor de Importancia. Se calculó el índice de diversidad de Shannon-Wiener y el de diversidad verdadera. La semejanza florística se estimó mediante análisis de agrupamiento; la asociación de especies y UM con ordenación por el índice Bray-Curtis. La riqueza florística en el pinar fue de 79 especies y en izotal 86; el índice de Shannon fue 1,47 y 1,34, respectivamente y fueron significativamente diferentes; el de diversidad verdadera 4,34 y 3,81 respectivamente. Ambas comunidades comparten 53 especies y presentan una semejanza florística del 49 %; mostraron diferencias significativas en la densidad y cobertura de especies. Este estudio contribuye al entendimiento de la estructura y el recambio de especies en la flora de comunidades de zonas secas de México.
