Resumen
Descripción
Grandes extensiones de bosques maduros y poco alterados se observan en las regiones centrales y del norte en la isla de Coiba, Panamá (7°29' N Y 81°45' W). En este trabajo registramos un total de 231 especies de plantas, de las cuales 203 fueron árboles y arbustos. Las familias con mayor número de especies fueron la Leguminosae, Rubiaceae, y Melastomataceae. El bosque de las tierras altas del centro de la isla es dominado por Calophyllum longifolium, Eschweilera pittieri, Cassipourea elliptica, y Ternstroemia tepezapote, mientras que en el bosque bajo de los alrededores predominan Calophyllum longifolium, Tetragastris panamensis, y Carapa guianensis. Pelliciera rhizophora, y Rhizophora mangle, son las especies más comunes en los manglares del sur de la isla, mientras que Prioria copaifera y Peltogyne purpurea se encuentran en mayor abundancia en los bosques en pantanos de agua dulce. Dentro del bosque mixto al norte de la isla, se establecieron dos parcelas de 20 x 20 m. En ellas marcamos y medimos los diámetros a la altura del pecho de todas las plantas leñosas mayores de 1 cm, exceptuando las trepadoras. Una tuvo 29 especies y 156 tallos, la otra 37 especies y 158 tallos. Estos niveles de diversidad son relativamente bajos si se comparan con parcelas de igual dimensión en bosques semejantes de tierra firme en Panamá.
Mature and Iittle-altered forest cover large expanses of the central and northem regions of Coiba island, Panamá (7°29' N; 8 1°45' W). A total of 231 species of plants, 203 of which were trees and shrubs, were recorded. The families with the most species were Leguminosae, Rubiaceae, and Melastomataceae. The higher elevation forest of the island center is dominated by Calophyllum longifolium, Eschweilera pittieri. Cassipourea elliptica, and Ternstroemia tepezapote, while Calophyllum longifolium. Tetragastris panamensis, and Carapa guianensis predominate in the surrounding, low-Iying foresto Pelliciera rhizophora and Rhizophora mangle are the most cornmon species of the mangrove forests along the southero shore of the island, and freshwater swamps are characterized by high densities of Prioria copaifera and Peltogyne purpurea. Within the variegated forest in the northero part of the island, we estabIished two 20 x 20 ro plots. Within each plot we rnarked and rneasured the diameter at breast height (dbh) of all woody plants greater than 1 cm dbh, excluding lianas. One plot yielded 29 species and 156 sterns, while the other had 37 species and 158 sterns. These levels of diversity are relatively low when compared to sarne-sized plots &oro comparable forest areas on mainland Panama.
