Microbial communities are an important component of mangrove ecosystems. In order to reveal the diversity of endophytic fungi in the mangrove ferns and in China, the internal transcribed spacer (ITS) regions of endophytic fungi in four plant tissues (leaves, petioles, roots, and rhizomes) from three locations (Zhanjiang, Haikou, and Wenchang) were sequenced. The richness, species composition, and community similarity were analyzed.

Within urban green spaces, tree species diversity is believed to correlate with aboveground biomass, though there is some disagreement within the literature on the strength and directionality of the relationship. Therefore, we assessed the relationship between the biodiversity of woody species and the aboveground biomass of woody plant species in the tropical, coastal city of Haikou in southern China. To accomplish this, we obtained comprehensive tree and site data through field sampling of 190 urban functional units (UFUs, or work units) corresponding to six types of land uses governmental-institutional, industrial-commercial, park-recreational, residential, transport infrastructure, and undeveloped area.

Hance is an endemic plant species distributed in southern China. In this study, we report and characterize the complete plastid genome sequence of in order to provide genomic resources helpful for promoting its conservation and garden utilization. The complete plastome is 153,526 bp in length and contains the typical quadripartite structure of angiosperm plastome, including two inverted repeat (IR) regions of 24,638 bp, a large single-copy (LSC) region of 85,417 bp, and a small single-copy (SSC) region of 18,833 bp.

Two-dimensional (2D) layered WS2 nanosheets have been regarded as exciting and emerging candidate materials in constructing high performance photodetectors. In this work, we develop a facile solvothermal method to synthesize oxygen-doped WS2 microrods composed of layer-by-layer stacked nanosheets. The WS2 microrods exhibit an obvious bandgap of 1.

Anthropogenic processes and socio-economic factors play important roles in shaping plant diversity in urban parks. To investigate how plant diversity of Ma' anling urban volcano park in Hainan Province, China respond to these factors, we carried out a field investigation on the taxonomic and phylogenetic diversity of vascular plants and soil properties in this area. We found 284 species of vascular plants belonging to 88 families and 241 genera, which included 194 native species, 23 invasive species, 31 naturalized species, 40 cultivars, and 4 rare / endangered plant species.
