Abstract:

Both unified neutral theory and niche theory have played an important role in understanding the mechanisms of species coexistence in tropical rain forests. Using Torus-translation tests, we examined the relationships between microtopography (elevation, convexity, and slope) and the distribution of 89 wood species with ≥5 individuals and diameter at breast height (DBH) ≥ 1.0 cm in a 5-ha permanent plot in a subtropical broad-leaved evergreen forest in Baishanzu, Zhejiang Province. We classified plants into three growth stages (sapling, juvenile and mature stages) based on their diameter-classes, and compared relationships between microtopography and the distribution of plants in different growth stages for each species. Species with less than 40 individuals always showed few associations with their habitats, while most common species in the 89 studied showed significant associations with their habitats. The majority of species exhibited shifts in habitat preference among growth stages; the exceptions were Rhododendron latoucheae, Cyclobalanopsis stewardiana and Cleyera pachyphylla, whose associations with habitats were similar at all stages. Our study suggests that topographical differentiation is important for maintaining species diversity in this subtropical broad-leaved evergreen forest, and that habitat associations of species change ontogenetically.
