The red imported fire ant ( Buren) is a highly adaptable invasive species that can nest and reproduce in different habitat soils. We aimed to explore the adaptability of red imported fire ants in different habitats by analyzing changes in the physicochemical properties of nest soils and bacterial communities. Five habitat types (forest, tea plantation, rice field, lawn, and brassica field) were selected. The results showed that the pH of the nest soils increased significantly in all five habitats compared to the control soils of the same habitat. A significant increase in nitrogen content was detected in the nests. The Cr, Pb, Cu, and Ni levels were significantly reduced in the soils of the five habitats, due to nesting activities. Analysis of the composition and diversity of the soil microbial community showed that, although the richness and diversity of bacteria in the nest soils of red imported fire ants in the five habitats varied, the relative abundance of Actinobacteria significantly increased and it emerged as the dominant bacterial group. These results indicate that red imported fire ants modify the physicochemical properties of nest soils and bacterial communities to create a suitable habitat for survival and reproduction.

Purpose Of The Study: 1,3,4,6-tetra-O-acetyl-2-O-trifluoromethanesulfonyl-β-D-mannopyranose (mannose triflate), the precursor used for the synthesis of [F] Fluorodeoxyglucose ([F] FDG) is imported from a few commercial suppliers abroad. As part of self-reliance, a reliable synthesis and characterization of mannose triflate has been developed, details of which are reported in this paper.
Materials And Methods: Synthesis of 1,3,4,6-tetra-O-acetyl-2-O-trifluoromethanesulfonyl-β-D-mannopyranose (Mannose triflate) carried by Triflation of 1,3,4,6-Tetra-O-acetyl-β-D-mannopyranose with Tf2O-pyridine under argon atmosphere for 6 h.

European livestock sectors rely heavily on imported protein feeds, presenting challenges regarding sustainability and supply security. Green biorefineries (GBR) represent a local alternative where protein concentrates are extracted from grassland crops, but the environmental performance of these systems depends on feedstock cultivation practices. This study combined field trials and life cycle assessment (LCA) to quantify how nitrogen (N) fertilization rates, clover inclusion rates, and feedstock management (fresh vs.

While foraging tunnels of the red imported fire ant, , have been well studied, much less is known about the tunnels constructed between neighboring nests, despite their perceived importance in intra-colony exchange and collaboration. In this study, we investigated such tunnels by excavating 80 pairs of nests (with distances of <1 m between nests) located in different types of habitats. For each pair of nests, we recorded the number of inter-nest tunnels and observed their shape, diameter, subsurface depth, and ant presence within them.

The red imported fire ant (RIFA; ) is an invasive species that severely threatens ecology, agriculture, and public health in Taiwan. In this study, the feasibility of applying multispectral imagery captured by unmanned aerial vehicles (UAVs) to detect red fire ant mounds was evaluated in Fenlin Township, Hualien, Taiwan. A DJI Phantom 4 multispectral drone collected reflectance in five bands (blue, green, red, red-edge, and near-infrared), derived indices (normalized difference vegetation index, NDVI, soil-adjusted vegetation index, SAVI, and photochemical pigment reflectance index, PPR), and textural features.
