06-2.43). In BKMR, the joint effect of the four-metal mixture on NTD risk increased steadily with the levels of the mixture. A change in Ba concentration from the 25th to 75th percentile displayed a risk effect when the other three metals were fixed at the 25th, 50th or 75th percentile, while such a change in Ca concentration showed a protective effect when the other metals were held at the 25th or 50th percentile. No interactions among metals were found. In the mouse experiment, dams treated with 200 mg/kg BaCl2 showed 16.8% of NTDs in fetal mice, compared to 2.6% in the untreated control group (P less then 0.01). Taken together, higher mixture levels of the four alkaline earth metals were associated with increased risk for NTDs, with Ba being the major contributor for the joint effect. Intragastric administration of Ba can induce NTDs in mice.In urban areas, green infrastructure (GI) has been widely developed utilizing different types of engineered soil to enhance ecosystem functions to interact with soil dissolved organic matter (DOM). However, there remains a lack of urban studies that have examined the link between GI features and soil DOM. This study, which was conducted in a typical heavily industrialized and urbanized area (Ningbo City, East China), aimed to characterize the chemical variation and composition of DOM in the engineered soil of four GI types (enhanced tree tips, ETP; street-side infiltration swales, SSIS; vegetated swales, VS; urban forests, UF). The results showed that soil organic carbon varies among the four GI types with significantly lower content in SSIS and ETP compared to VS and UF. Smaller variation was observed in the water-soluble organic carbon (WSOC) content, with UF having significantly higher content than ETP. Three humic-like substances and one protein-like substance were derived using the parallel factor analysis (PARAFAC) model. These fluorescent compositions and their spectral parameters displayed specific distributions among GI features with VS having the highest proportion of humic-like substances (C1) and the lowest proportion of protein-like substances (C4). The distribution of spectral indices indicated terrigenous sources of DOM in these GI engineered soils. Significant positive correlations were found between protein-like substances and the population density and nightlight index, while negative correlations were found between humic-like substances (C1) and these two indices. These results demonstrate significant human disturbance of the chemical composition and characteristics of GI features. Our findings suggest that the overall design and management of GI features have a fundamental influence on soil DOM that is vital for carbon cycling in urban ecosystems.Understanding the driving mechanisms of local genetic diversity is a fundamental challenge under the global environmental changes. Rivers provide an excellent study system to demonstrate the effects of hydrochory dispersal and habitat selection on genetic diversity of riparian flora. In this study, we focused on the genetic variation of common reed (Phragmites australis) in the Yellow River Delta, China. Firstly, samples were collected in the Yellow River Delta, its neighboring wetland and its upstream plain. The genetic variation of P. australis was investigated using two chloroplast DNA fragments and eleven nuclear microsatellites. The findings showed that the genetic variation of P. australis in the Yellow River Delta belonged to two distinct lineages (haplotype O and haplotype P), which were similar to the upstream, and to the neighboring populations, respectively. Moreover, the genetic results suggested the potential dispersal of haplotype O from upstream to downstream. Secondly, we surveyed the plant functional traits of common reed from the Yellow River Delta in the field and in the common garden. The results showed significant differences between riverine and non-riverine populations in plant functional traits (e.g. specific leaf area and leaf length), haplotype composition and genetic clustering, which implied natural selection by habitat conditions. Lastly, we re-analyzed the plant performance data from a salt manipulation experiment with different haplotypes, and the results supported that salinity is a significant selective stressor on P. australis lineages in the Yellow River Delta. selleck Our study highlights the significance of hydrochory dispersal and habitat selection in the river effects on genetic diversity of riparian flora, and provides important information for biodiversity conservation and wetland management in the Yellow River Delta.Visceral leishmaniasis (VL) is a neglected disease caused by trypanosomatid protozoa in the genus Leishmania, which is transmitted by phlebotomine sandflies. Although this vector-borne disease has been eliminated in several regions of China during the last century, the reported human VL cases have rebounded in Western and Central China in recent decades. However, understanding of the spatial epidemiology of the disease remains vague, as the spatial risk factors driving the spatial heterogeneity of VL. In this study, we analyzed the spatiotemporal patterns of annual human VL cases in Western and Central China from 2007 to 2017. Based on the related spatial maps, the boosted regression tree (BRT) model was adopted to explore the relationships between VL and spatial correlates as well as predicting both the existing and potential infection risk zones of VL in Western and Central China. The mined links reveal that elevation, minimum temperature, relative humidity, and annual accumulated precipitation make great contributions to the spatial heterogeneity of VL. The maps show that Xinjiang Uygur Autonomous Region, Gansu, western Inner Mongolia Autonomous Region, and Sichuan are predicted to fall in the highest infection risk zones of VL. Approximately 61.60 million resident populations lived in the high-risk regions of VL in Western and Central China. Our results provide a better understanding of how spatial risk factors driving VL spread as well as identifying the potential endemic risk region of VL, thereby enhancing the biosurveillance capacity of public health authorities.
