Structure and diversity of arboreal vegetation in coffee agroforestry systems in Sierra de Atoyac, Veracruz
Structure and tree diversity was studied in coffee agroforestry systems (SAF-café): rustic (RU), polyculture complex (PC), simple polyculture (PS), and as semi-evergreen forest (SM) from the Sierra de Atoyac, Veracruz, establishing three sampling units (UM) per altitudinal band (600-900 and 900-1200...

| description | Structure and tree diversity was studied in coffee agroforestry systems (SAF-café): rustic (RU), polyculture complex (PC), simple polyculture (PS), and as semi-evergreen forest (SM) from the Sierra de Atoyac, Veracruz, establishing three sampling units (UM) per altitudinal band (600-900 and 900-1200) m on each system and forest above mentioned, for a total 24 UM of 600 m2 (20 m x 30 m) each one. Each system was characterized by the diameter and height distribution of individuals as well as the calculated importance value (IVI), forest value (IVF), diversity (Shannon H ‘, α Fisher) and floristic similarity (Sorensen: Si) indices. To analyze patterns of species distribution of vegetation classification (cluster analysis: β flex) and ordination (canonical correspondence analysis: CCA) techniques were applied. 79 tree species were determined, richness per system was: SM= 65; PC= 61; RU= 32; PS= 18. Cordia alliodora (Ruiz & Pav.) Cham. was the most important structurally species in the SAF-café coffee and Myriocarpa longipes Liebm., and Bursera simaruba (L.) Sarg. in the SM. The diversity was significantly higher in PC (H ‘= 3.56) and SM (H ‘= 3.58) without significant differences (p < 0.05) between them. The highest floristic similarity was between SM and PC (Si = 0.69). Also the altitude was the most influential environmental factor in the floristic composition of the systems. |

Se estudió la estructura y diversidad arbórea en sistemas agroforestales de café (SAF-Café): rusticano (RU), policultivo complejo (PC) y policultivo simple (PS), así como en una selva mediana subperennifiolia (SM) de la Sierra de Atoyac, Veracruz, estableciéndose tres unidades de muestreo (UM) por cada franja altitudinal (600-900 y 900-1200) m snm en cada sistema y selva mencionados, para un total de 24 UM de 600 m2 (20 m x 30 m) cada una. Caracterizándose cada sistema mediante la distribución diamétrica y de alturas de sus individuos así como con el cálculo de índices de valor de importancia (IVI), de valor forestal (IVF), de diversidad (Shannon: H’, α Fisher) y de semejanza florística (Sorensen: Si). Para analizar patrones de distribución de especies, se aplicaron técnicas de clasificación (agrupamiento: β flex) y ordenación (correspondencia canónica: CCA) de la vegetación. Fueron determinadas 79 especies arbóreas, la riqueza por sistema fue: SM=65; PC=61; RU=32; PS=18. Cordia alliodora (Ruiz & Pav.) Cham. resultó ser la especie más importante estructuralmente en los SAF-café, Bursera simaruba (L.) Sarg. y Myriocarpa longipes Liebm. en la SM. La diversidad fue significativamente mayor en PC (H´=3.56) y SM (H´=3.58) sin presentar diferencias significativas (p < 0.05) entre estos. La semejanza florística mayor fue entre SM y PC (Si =0.69). Asimismo la altitud fue el factor ambiental que más influyó en la composición florística de los sistemas.
