Species composition, physiognomy and plant diversity of the tropical montane evergreen broad-leaved forest in southern Yunnan

Sexual Systems and Ecological Correlates in an Azonal Tropical Forests, SW China

“…Most plots were 25 × 20 m in area, and all trees in those plots were identified. In each plot, five 5 × 5 m subplots were set for floristic survey of the understory including herbs (Zhu et al 2005). In a few plots, only species with dbh > 5 cm were recorded (Zhu et al 1998a, b).…”

Elevational Distribution of Adult Trees and Seedlings in a Tropical Montane Transect, Southwest China

“…The relative narrowness of the elevational distributions of dominant tree species is caused by opposing environmental constraints (Williams et al 2010; Arellano and Mac ıa 2014). The vegetation changes observed in our study were likely influenced by strong seasonal dryness (and perhaps temperaturediscussed later), with tropical rain forest occurring in wet valleys and tropical montane evergreen broad-leaved forest occurring in dry montane habitats (Zhu et al 2005).…”

“…Species composition was more similar for both adult trees and seedlings at high elevations (Figure 3). This may have resulted from drier environmental conditions at high elevations acting as an environmental filter and reducing species richness (Zhu et al 2005;Cao et al 2006). Aggregation of high-elevation plots was observed in NMDS ordinations of all 4 similarity indices, including the Raup Crick index (a probabilistic measure unaffected by the number of species-Chase et al 2011), suggesting that the high similarity of these plots is not a simple artifact caused by depauperate flora at these elevations.…”

“…This study aimed to help fill that gap with an investigation in Xishuangbanna Dai Autonomous Prefecture in southwestern China, an area rich in biodiversity across various types of seasonal tropical forests (Cao and Zhang 1997;Zhu et al 2006). A number of studies of forest species composition and assemblage structures have been conducted in this region (Wu 1980;Wu et al 1987;Zhang and Cao 1995;Cao and Zhang 1997;Zhu et al 2005;. In Xishuangbanna, vegetation below 800 m in elevation has been classified as tropical seasonal rain forest, vegetation between 1000 m and 1200 m as tropical montane rain forest, and vegetation between 1200 m and 1400 m as tropical montane evergreen broad-leaved forest (Wu et al 1987).…”
