A new species of Gesneriaceae, S.J.Ling, F.Wen & M.X. Ren from Hainan Island, south China, is highlighted and described. The new species is distinguished by its actinomorphic corolla, narrow floral tube and ovate anthers hidden in the floral tube. The new species also showed clear geographic and altitudinal isolation from the three currently-recognised species on the Island. Molecular phylogenetic analysis, based on nuclear ITS1/2 and plastid L-F sequences, supported the delimitation of the new species, which forms a single lineage with all the other species from Hainan Island. The roles of geographic and floral isolation in the evolution of the new species and its affinities are discussed.

As the third largest class of dyes in the world, triphenylmethane dyes are widely applied in colorimetric sensing. However, triphenylmethane dyes are commonly nonfluorescent, which limits their sensing applications. It is worthwhile to study the fluorescence off/on control of triphenylmethane dyes and promote the applications of triphenylmethane dyes in sensing technology.

Tourism, as an important manifestation of urbanization, is becoming increasingly popular. Although it offers numerous advantages for the local community, it also exerts a multifaceted impact on local wildlife. Previous research on the effects of tourism has mainly focused on protected areas or tourist spots, rarely considering the surrounding non-tourist attraction areas.

Emerging organophosphate flame retardants (E-OPFRs) are a new class of pollutants that have attracted increasing attention, but their bioaccumulation patterns and trophodynamic behaviors in aquatic food webs still need to be validated by comparison with legacy OPFRs (L-OPFRs). In this study, we simultaneously investigated the bioaccumulation, trophic transfer, and dietary exposure of 8 E-OPFRs and 10 L-OPFRs in a tropical estuarine food web from Hainan Island, China. Notably, the ΣL-OPFRs concentration (16.

As one of the neonicotinoid insecticides, thiacloprid (THI) is extensively used in agriculture and frequently detected in various aquatic environments, posing a potential threat to aquatic organisms. However, the effects of THI exposure on aquatic turtles remain unknown. In this study, we focused on investigating whether THI has a toxic effect on the gut-liver axis in aquatic turtles.

To assess the environmental status of an abandoned aquaculture and breeding area in the northeast coast of the Hainan Island, surface and well water, sediment and surface soils were sampled and analyzed for conventional physicochemical properties, heavy metals and antibiotics. Metagenome tests were also conducted to determine the composition and diversity of the microbial community in typical habitats. Affected by the discharge of wastewater from higher-place pond aquaculture, coastal freshwater rivers have undergone significant salinization, Cl and Na were as high as 4.
