Tree canopy composition in the tropical mountain rainforest of los Tuxtlas, Mexico
We studied the arboreal composition of the tropical mountain rainforest’s upper canopy in the San Martín Pajapán volcano, Tatahuicapan, Veracruz, México (18°26’ N; 94°17’ W). Two forest stands were studied, one in an exposed position and one protected. The Shannon index of diversity and the Jaccard...

| description | We studied the arboreal composition of the tropical mountain rainforest’s upper canopy in the San Martín Pajapán volcano, Tatahuicapan, Veracruz, México (18°26’ N; 94°17’ W). Two forest stands were studied, one in an exposed position and one protected. The Shannon index of diversity and the Jaccard index of affinity were calculated to calculate affinities between plots and between stands of different environmental exposures. The average Shannon value was 3.391 +0.121 for the exposed zone and 3.511 +0.53 for the protected zone. There is a greater species number and tree density in the exposed stand. This difference might be caused be different orientation to dominant winds. The diversity index value is high is similar between the stands, despite the important difference in species composition. Rev. Biol. Trop. 56 (3): 1571-1579. Epub 2008 September 30.<br>El objetivo de este trabajo fue conocer la composición arbórea del bosque tropical lluvioso en el volcán de San Martín Pajapán. Se comparan dos áreas en diferente exposición: expuesta a los vientos dominates y protegida de los vientos. El valor medio del índice de diversidad de Shannon es de 3.391 +0.121 para la zona expuesta y 3.511 +0.53 para la protegida. El número de especies y la densidad de árboles por hectárea es mayor en la zona expuesta y la composición de especies es muy diferente entre las parcelas. |
