To understand the effect of moso bamboo (Phyllostachys edulis) expansion on the community structure and species diversity of different artificial forests, continuous ecological interfaces from a moso bamboo stand to a Chinese fir (Cunninghamia lanceolata) stand, and broad-leaved forest (dominated by Camptotheca acuminata+Sassafras tzumu) were selected to set transects. The results showed that the density of moso bamboo increased with the expansion to Chinese fir stand or broad-leaved forest, accompanied by an increase in bamboo density but a decreasein the original species. Bamboo expansion changed the community height and diameter at breast height (DBH) structures, such that the range of height in the community narrowed from 2-14 m in the Chinese fir stand and 6-20 m in the broad-leaved forest to 10-16 m in the bamboo stand, accounting for 91.79% and 80.45% of the total, respectively. In addition, the main range of DBH narrowed from 3-20 cm in the Chinese fir stand and 5-35 cm in the broad-leaved forest to 5-15 cm in the bamboo stand, accounting for 94.78% and 96.99% of the total, respectively. Margalef index and Shannon-Wiener index of shrub and herb layers increased during the expansion of moso bamboo to C. lanceolata and broad-leavedforest.Species evenness and dominance of the shrub layer did not change significantly; however, species evenness of the herb layer increased. At the same time, the S?rensen index and Jaccard index of the herb layer were significantly higher than those of the shrub layer. The Cody index was lower in the herb layer than in the shrub layer in the Chinese fir forest expansion but was close to that in the broad-leaved forest expansion. Overall, our results indicate that bamboo expansion would further simplify the community structure of second forests, but increase species diversity in shrub and grass layers. The understory vegetation in the Chinese fir stand exhibited an obvious increasing species turnover rate during bamboo expansion, but this was different in the expansion to broad-leaved forest.

Deciduous broad-leaved forests are one of the typical forest vegetation types in the subtropical karst hills. In order to understand the community type and composition structure of this type of forest vegetation, we established forty-nine 20 m × 20 m random plots in deciduous broad-leaved forests with typical karst habitats in Yangshuo County and Lingchuan County of Guilin. We conducted an in-depth analysis of the coupling relationship from different community types, structures, and environmental factors. The results were as follows:(1)The deciduous broad-leaved forests in the karst hills could be classified into three community types based on quantitative methods, Ass. Choerospondias axillaris-Camptotheca acuminata+ Croton tiglium (Association Group A), Ass. Swida wilsoniana-Camptotheca acuminata(Association Group B), Ass. Quercus acutissima-Loropetalum chinense(Association Group C).(2)The species richness, species abundance, basal area, and the importance value for evergreen and deciduous species were different for each community type. Deciduous species were dominant in the tree layer for all three association groups. Shrub layer for Association Group A and Group B were also dominated by deciduous species, while Association Group C was dominated by evergreen species.(3)The species richness, species abundance, basal area and importance value of deciduous species in Association Group A and Group B were greater than evergreen species within the 1-5 cm and 5-10 cm diameter classes. In Association Group C, all indicators were greater for evergreen species than deciduous species for the 1-5 cm and 5-10 cm diameter classes. For the ≥10 cm diameter class, deciduous species were dominant for all indicators in all three association groups except for the species richness in Association Group B.(4)The rock bare rate, soil water content, elevation, aspect, pH, soil organic matter, total nitrogen, available nitrogen, available potassium, canopy openness and human disturbance gradient were the dominant factors affecting the distribution of different types of communities in the study.

This study explored the bole epiphytic bryophytes in the tropical rainforest and the tropical montane evergreen broad-leaved forest in Xishuangbanna, aimed to reveal their composition, diversity patterns, and maintenance mechanisms. The study site is located in Mengla County. Ten sampling plots(20 m × 20 m)of each vegetation type were chosen, and about ten tree individuals were sampled in each plot to survey the bole epiphytic bryophytes. The results were as follows:(1)In total, 60 species belonging to 39 genera and 20 families were recorded. Among them, 48 species belonging to 33 genera and 19 families were recorded in the tropical rainforest, and 19 species belonging to 14 genera and 9 families were recorded in the tropical montane evergreen broad-leaved forest.(2)The dominant family of the tropical rainforest is Neckeraceae, while the dominant family of the tropical montane evergreen broad-leaved forest is Sematophyllaceae.(3)The species richness, β and γ diversities of the tropical rainforest were higher than the tropical montane evergreen broad-leaved forest.(4)The coverage of epiphytic bryophytes was significantly different among different diameter classes and bark roughness.(5)Pendants, fans, wefts, and rough mats prefer the tropical rainforest, while turfs, cushions, smooth mats gather in the tropical montane evergreen broad-leaved forest.(6)The results of redundancy analysis showed that host characteristics, especially bark roughness, significantly affected the composition and distribution of life forms. Tropical rainforest provide a greater diversity of microhabitats than tropical montane evergreen broad-leaved forest, and thus harbor more epiphytic bryophyte species than the latter. Considering different bryophyte life form were recorded in different vegetation types or host characteristics, life forms can be considered as an important indicator for forest monitoring and management.

In order to gain insight into the species diversity and functional diversity of forest vegetation in karst hills and their relationships with environmental factors. We analyzed the species diversity and functional diversity of deciduous broad-leaved forest, mixed evergreen and deciduous broad-leaved forest, and evergreen broad-leaved forest in karst hills of Guilin through community investigation, determination of functional traits and environmental factors. And in combination with statistical methods such as one-way analysis of variance, multiple comparisons, and redundancy analysis to investigate the impact mechanisms of environmental factors on the species diversity and functional diversity of different vegetation types. The results were as follows:(1)The Patrick richness index was significantly higher in evergreen broad-leaved forest than that in deciduous broad-leaved forest, and mixed evergreen and deciduous broad-leaved forest. The Pielou evenness index of mixed evergreen and deciduous broad-leaved forest was the highest, followed by deciduous broad-leaved forest and the lowest in evergreen broad-leaved forest.(2)The functional richness index of evergreen broad-leaved forest was significantly higher than that of mixed evergreen and deciduous broad-leaved forest and deciduous broad-leaved forest; the functional evenness index was the highest in mixed evergreen and deciduous broad-leaved forest, the second in deciduous broad-leaved forest, and the lowest in evergreen broad-leaved forest.(3)Redundancy analysis combined with Monte Carlo random replacement test results indicated that species diversity of deciduous broad-leaved forest was mainly affected by canopy openness and soil water-soluble calcium. Functional diversity was affected by soil water-soluble calcium and rock exposure rate. Rock exposure rate and soil thickness were the main restricting factors that affect species diversity and functional diversity of mixed evergreen and deciduous broad-leaved forest. In addition, species diversity was significantly affected by soil available nitrogen. The influencing factors of species diversity and functional diversity of evergreen broad-leaved forest were consistent, and they were all significantly affected by rock exposure rate, soil water content and soil thickness. The results of this study reveal the effects of species diversity and functional diversity of different forest vegetations on non-biological environmental changes, expand the understanding of species diversity and functional diversity of karst hills, and provide further reference for biodiversity protection of karst hills.

By exploring the species diversity and soil physical and chemical properties of four typical forest types (natural broad-leaved mixed forest, artificial broad-leaved mixed forest, artificial broad-leaved pure forest, and artificial coniferous and broad-leaved mixed forest) in Zengcheng District, Guangzhou City, based on their origins and stand types, we analyzed their species diversity differences and the relationship between them and soil environmental factors, providing a theoretical basis for improving the quality of natural forests accurately. Using the typical quadrat survey method and statistical analysis methods, we calculated the Magalef richness index, Shannon-Wiener index, and Simpson dominance index to analyze the differences in species composition, dominance, and species diversity of the arbor and shrub layers in typical forest communities in Zengcheng District, and conducted correlation analysis with soil environmental factors. A total of 193 species belonging to 82 families and 153 genera were surveyed in the study area. The dominant species and their importance values of the four forest types were as follows: natural broad-leaved mixed forest (Machilus thunbergii, 6. 36%), artificial broad-leaved mixed forest (M. thunbergii, 5. 52%), artificial broad-leaved pure forest (Eucalyptus, 29. 54%), and artificial coniferous and broad-leaved mixed forest (Canarium, 4. 73%). The dominant species in natural and artificial broad-leaved mixed forests showed an inverted J-shaped distribution, while artificial coniferous and broad-leaved mixed forests and broad-leaved pure forests showed a normal distribution. The four forest types had significant differences in species diversity, soil nitrogen, and phosphorus content. Among them, the artificial broad-leaved pure forest had the lowest species diversity in the arbor layer and the highest species diversity in the shrub layer. The soil nutrient content of the four forest types varied significantly, and there was a significant correlation between species diversity and soil physical and chemical properties. Forests of different origins and stand types in the region require different management measures. [ABSTRACT FROM AUTHOR]

A better understanding of the spatiotemporal dynamics of species composition and biodiversity provides significant insights into the distribution patterns of biodiversity and the prediction of biodiversity fate in a global change context. However, how species and phylogenetic diversity change along elevational gradient with temporal scale in mountain ecosystems is still unknown. In this study, we used census data (2004, 2008 and 2013) of an elevational transect (elevational range 9602878 m) covering eastern and western slopes of Gaoligong Mountains, SW China, to investigate the spatiotemporal dynamics of forest arbor layer (DBH≥5 cm) species composition, species diversity and phylogenetic diversity. The results were as follows: (1) Species diversity was hump-shaped along the elevational gradient, while the phylogenetic diversity increased with increasing elevation. Clustering phylogenetic structure was observed at low elevations, and over dispersed or random structure was detected at high elevations. (2) Overall, temporal species and phylogenetic beta diversity analysis showed no significant difference among these three investigation time points. However, we found a higher clustering of phylogenetic structure along the temporal scale. (3) Spatial beta diversity showed that there was a significant loss of species at low elevations (960 1 381 m) on the eastern slope, where the vegetation had been disturbed or completely converted into farmland. The main lost species including Terminalia chebula, Quercus acutissima, Pistacia weinmanniifolia, Hovenia acerba and Ilex wattii. In contrast, the change in the western slope was mild at low elevations, only observing species abundance increasing, which including Cyclobalanopsis oxyodon, Symplocos chinensis, and Taiwania cryptomerioides. Therefore, we speculated that the dynamic changes in species and phylogenetic diversity of the arbor layer of subtropical evergreen broadleaf forest might be related to communities succession process and climatic change in middle and high elevations, while the communities at low elevations were seriously impacted by human activities in Gaoligong Mountains. The results deepen the understanding of the mechanisms of plant community dynamics in Gaoligong Mountains, and provide new insights to guide precise conservation strategies in the region.

Exploring the mechanism of species coexistence based on functional traits has become a hot topic of community ecology in recent yews. This study was aimed to understand the reasons for the establishment of the vertical structure, and to investigate the functional traits of plant leaves at different layers of the semi-humid evergreen broad-leaf forest in Qiongzhu Temple, Kunming. The results were as follows: ( 1) All plant functional traits showed varying degrees of trends at different layers. (2) The Castarwpsis orthacantha community was divided into three layers according to plant life forms, i.e. tree, shrub, and herb, which were consistent with the clustering results of functional traits. (3) The S.E.S PW values at the tree, shrub and herb layers were all < 0, indicating that the functional structure in the community exhibited a significant divergence. In summary, the adaptation of leaf functional trails of different species in plant communities to different combinations of light and water conditions in the vertical direction of the community, was the main influence on the establishment of the vertical structure, which supporting habitat filtering is the main ecological process in the establishment of the vertical milldam. Species at different layers had different functional trails, and the species diversity at the same layer increased through the varying degrees of competitive exclusion. The formation of community vertical structure was the result of changes in environmental factors in the vertical direction within the community; species with different needs for resources were distributed at different heights, and vertical structure was an effective use of resources, and increased species diversity within the community.
