dc.description.abstract | La fragmentacón de un bosque genera cambios en muchos aspectos bióticos y abióticos de los pares remanentes. En este estudio describe la composición florística de un fragmento de bosque en el departamento del Guaviare, Colombia, analizando el efecto de borde y factores abióticos. Se establecieron diez parcelas de 100 x 10 m se muestrearon todas las especies delos árboles con DAP >= 10 cm. El índice de importancia mostró que las especies con mayores valores fueron Iriartea deltoidea, Croton matourensis y Pouroma minor. Se estableció que las especies cercca al borde corresponden mayormente a plantas pioneras (de semillas pequeñas) y las especies lejos de éste son principalmente de bosque maduro (de semillas grandes). Una ordenación demostró que cada una de las parcelas posee una composición florística relativamente diferente, que no se explica por factores como característica del suelo o temperatura, aunque la humedad parece jugar un papel importante. La distancia entre las parcelas tampoco fue un buen predictor de la composición florística, indicando que, cuando se mantiene los dispersores de semillas, la disperción limitada o opera fuertemente a las escalas espaciales estudiadas. El fragmento a las escalas espaciales estudiadas presenta una composición con muchos elementos típicos de un proceso de sucesión, aunque conserva una gran diversidad de especies de los bosques originales. Concluimos que la fragmentacón ha ocasionado cambios en términos de la composición florística y se recomiendo adoptar medidas para detener esteproceso, con el fin de mantener parte ed la composición y los procesos ecológicos de los bosques nativos. | spa |
dc.description.abstract | fragmentation generates changes in biotic and abiotic factors of remnants. The aim of this study was ti describe the floral composition of a forest fragment in Guaviare, Colombia, in relation to the edge effect and abiotic factors. Ten plots of 100m x 10 m were sampled. The importance value index showed that the most important species in the fragment were Iriartea deltoidea, Croton matourensis, and Pourouma minor. Additionally, it was established that the species found near the edge were mainly pioneer plants (small seeded species) while the species away from it corrsponded primarily to mature forest plants (small seeded species) while the species away from it corresponde primarily to mature forest plants (with large seeds). An odination demostrated that each plot had a relatively different floristic composition, which could not be explained by soil composition or temperature. However, humidity seems to play an important role. The distance between plots was not a good predictior of floristic affinities, suggesting that when the seed dispersal vectors are maintained, dispersal limitation has weak effects at the spatial scales studied.The fragment exhibits typical elements of a succesional process, although in harbors a high especies diversity from the original forest. We conclude that fragmentation has caused changes in terms of floral composition, and its necessary to take measures to stop this process in order to maintain part of the floristic composition and the ecological processes of the native forest. | eng |
