In tropical forests, the environmental heterogeneity can provide niche partitioning at local scales and determine the diversity and plant species distribution. Thus, this study aimed to investigate the variations of tree species structure and distribution in response to relief and soil profile features in a portion of the largest remnant of Brazilian Atlantic rain forest. All trees ³ 5 cm diameter at breast height were recorded in two 0.99 ha plots. Topographic survey and a soil characterization were accomplished in both plots. Topsoil samples (0-20 cm) were taken from 88 quadrats and analyzed for chemical and particle size properties. Differences for both diversity and tree density were identified among three kinds of soils. A canonical correspondence...

Tree diversity in sub-montane and lower montane primary rain forests in Central Sulawesi
Provedor de dados: Naturalis Digital Academic Repository
Autores: Culmsee, H.; Pitopang, R.
The tree diversity of sub-montane and lower montane primary forests is studied in plot-based inventories on two sites in Lore Lindu National Park, Central Sulawesi. Out of 166 species in total, 50 % are new records for Sulawesi (19 %) or the Central Sulawesi province (31 %). Species richness decreases with altitude. In the submontane forest, the highest Family Importance Values (FIV) are reached by the Lauraceae, Fagaceae, Sapotaceae, Moraceae and Euphorbiaceae. In the lower montane forest, the Fagaceae are of major importance (FIV 71.9), followed at some distance by the Myrtaceae, Elaeocarpaceae and Lauraceae. For each site, a group of important families is identified that is of minor importance or absent on the other site. The comparison of basal area...
