To better understand the response and adaptation of plants to altitudinal changes, four sites at the altitude of 2200 m, 2500 m, 3100 m and 3400 m on Balang Mountain were selected to test and calculate the eco-physiological parameters in leaves of Betula utilis, including photosynthetic nitrogen use efficiency (PNUE), CO diffusion conductance (stomatal conductance g and mesophyll conductance g) and nitrogen allocation in each component (fractions of leaf nitrogen allocated to Rubisco P, to bioenergetics P, to light-harvesting components P, and to cell wall P). Their changes with altitudinal variations and the relationships between leaf PNUE and the other parameters were analyzed. The results showed that PNUE, P, and P of the leaves were relatively higher at 2500 m and 3100 m.

A total of 13 phenotypic traits from 11 natural populations of Cupressus chengiana were investigated by using nested analysis, variation coefficient, phenotypic traits differentiation coefficient, and un-weighted pair-group method by arithmetic averages (UPGMA) cluster analysis. Phenotypic variations among and within populations of C. chengiana were discussed, the relationship among phenotypic traits and that between phenotypic traits and environmental factors were analyzed, and the 11 populations were divided.

Article Synopsis
  • Researchers studied 11 functional traits of canopy trees in tropical montane rainforest plots on Hainan Island to understand how species abundance affects functional diversity.
  • They used metrics like mean pairwise distance (MPD) and mean nearest taxon distance (MNTD) to assess how tree traits and abundance relate to biodiversity and local habitat differences.
  • Results indicated that while MPD was influenced by trait dimensions and abundance, MNTD displayed stronger correlations between weighted and non-weighted values; overall, functional richness increased with species abundance, hinting at a potential threshold.

The effects of three plantation stands, Erythrophleumf ordii (EF), Pinus massoniana (PM), and their mixed plantation (MP), on soil microbial biomass and microbial community structure in south subtropical China were studied by the method of phospholipid fatty acids (PLFAs) analysis. The results showed that the amounts of microbial total PLFAs and PLFAs of each microbial group in these three plantation stand soils were significantly higher in dry season than in rainy season. In dry season, the amounts of microbial total PLFAs, bacteria PLFAs, fungi PLFAs, and actinomycetes PLFAs were the highest in the PM soil, moderate in the MP soil, and the lowest in the EF soil.
