| 英文摘要 | Asplenium nidus is an abundant epiphytic fern of tropical rain forests in the old world, where it plays an important ecological role in the forest canopy as host to diverse arthropod communities. we investigated the factors that determine the distribution and abundance of a. nidus in the canopy of an aseasonal lowland dipterocarp forest at pasoh forest reserve, malaysia. we found that a. nidus was more abundant in the understory, and on hosts with smooth bark and relatively flat branch angles. ferns were found on a wide diversity and size range of host taxa. however, both host taxa and host diameter at breast height had a significant effect on a. nidus occupancy. asplenium nidus had an aggregated spatial distribution at all scales within the study area. spatial aggregation at larger scales appears to be driven by habitat preference, as a. nidus abundance was positively associated with swampy areas and negatively associated with hilly areas. at smaller scales, limited dispersal of their wind-dispersed spores most likely explains the aggregated distribution. larger individuals occurred higher in the canopy and were more common in the hilly area. thus, the distribution of a. nidus may represent a trade-off between the availability of suitable microsites for establishment in the understory and better growth conditions higher in the canopy. however, a. nidus is known to comprise a complex of cryptic species, and future studies should incorporate molecular techniques to elucidate the potential role of speciation in explaining these patterns. |
