ABSTRACT
Rapid urban development poses a threat to global biodiversity. At the same time, urban green spaces offer opportunities for holding biodiversity in cities. Among biological communities, the soil fauna plays a crucial role in ecological processes but is often ignored. Understanding the effects of environmental factors on soil fauna is critical for ecological conservation in urban areas. In this study, five typical green space habitats were selected including bamboo grove, forest, garden, grassland, and wasteland in spring, for detecting the relationship between habitats and Armadillidium vulgare population characteristics in Yancheng, China. Results indicate that soil water content, pH, soil organic matter, and soil total carbon varied significantly among habitats, as well as the body length and body weight of pill bugs. The higher proportion of larger pill bugs was found in the wasteland and the lower proportion in the grassland and the bamboo grove. The body length of pill bugs was positively related to pH. Soil total carbon, soil organic matter, and the number of plant species were correlated with the body weight of pill bugs.
ABSTRACT
The development of a lysosome-targeting fluorescent probe to visualize endogenous and exogenous methylglyoxal (MGO) in live cells has important implications for associated diseases. Herein, a lysosome-targeting fluorescent probe MGO-Naph-A was designed and synthesized to detect MGO with high selectivity. The probe contained naphthalimide as the fluorescent group, o-phenylenediamine as the MGO recognition group, and morpholine as the lysosome targeting group. This fluorescent probe could detect endogenous and exogenous MGO in living cells by precisely targeting and staining lysosomes. It could also detect MGO in living zebrafish. The results showed that the probe MGO-Naph-A has the potential to visualize MGO in lysosomes.
