Efecto de la estructura de la vegeta ción sobre la distribución y riqueza de macro hongos en Isla Palma, Pacífico Colombiano

Abstract

The aim of this work was to study the macrofungal richness and relate its variation with environmental variables and vegetation structure in Isla Palma, Colombian Pacific region. For this, nine fixed 10x10 m plots were established, distributed in three 90 m long paths, perpendicular to the Eastern coast of the island, starting 20 m away from the tide line, and separated 60 m from each other. Macrofungi were collected in each plot monthly for six months. Vegetation parameters and light intensity were also measured. One hundred-seven (107) macrofungal morphospecies were found, being Marasmius and Mycena the dominant genera. Macrofungi richness was not related to vegetation parameters or with the light intensity; however, these parameters were related to the composition of macrofungi in the forest.
