“…Temperature, rainfall, salinity, and other environmental factors have an impact on the distribution and growth of S. alopecuroides. Wang [30]'s study found that the annual average temperature, annual variation range for temperature, average temperature of the driest quarter, precipitation of the warmest quarter, and altitude are important factors affecting the distribution of S. alopecuroides. Yao [31]'s study found that the main ecological factors affecting the distribution of S. alopecuroides are altitude and precipitation in the coldest season.…”

Sophora alopecuroides L., a perennial herb in the arid and semi-arid regions of northwest China, has the ecological functions of windbreaking and sand fixation and high medicinal value. In recent years, global warming and human activities have led to changes in suitable habitats for S. alopecuroides, which may affect the accumulation of natural products. In this study, MaxEnt 3.4 and ArcGIS 10.4 software were used to predict the distribution of potentially suitable habitats for S. alopecuroides in China under climate change. Furthermore, the geographical distribution of S. alopecuroides as affected by human activities, the differences in the content of natural products of S. alopecuroides between different suitable habitats, and the correlation between natural products and environmental factors were analyzed. The results showed that suitable habitats for S. alopecuroides were projected to expand in the future, and the major environmental factors were temperature (Bio1), rainfall (Bio18), and soil pH (pH). When Bio1, Bio18, and pH were 8.4283 °C, 7.1968 mm, and 9.9331, respectively, the distribution probability (P) of S. alopecuroides was the highest. After adding a human activity factor, the accuracy of the model prediction results was improved, and the area of suitable habitats was greatly reduced, showing a fragmented pattern. Meanwhile, habitat suitability had a specific effect on the content of natural products in S. alopecuroides. Specifically, the content of natural products in S. alopecuroides in wild habitats was higher than that in artificial cultivation, and highly suitable habitats showed higher contents than those in non-highly suitable habitats. The contents of total alkaloids and total flavonoids were positively correlated with human activities and negatively correlated with land use types. Among them, total alkaloids were negatively correlated with aspect, and total flavonoids were positively correlated with aspect. In addition, it is suggested that Xinjiang should be the priority planting area for S. alopecuroides in China, and priority should be given to protection measures in the Alashan area. Overall, this study provides an important foundation for the determination of priority planting areas and resource protection for S. alopecuroides.

Aim: Species diversity in the region of the Qinghai-Tibet Plateau has been extensively explored, whereas the distribution of genetic diversity remains poorly understood in this species-rich area, parts of which are listed as biodiversity hotspots. In this study, we aimed to map the patterns of genetic diversity and divergence of plant species in this region, and to identify potential evolutionary hotspots for conservation planning.Location: Region of the Qinghai-Tibet Plateau (QTP). Methods:We compiled published molecular data for 60 plant species, and calculated intra-population genetic diversity and inter-population genetic divergence using haplotype sequences (chloroplast or mitochondrial DNA). We analysed the relationships between genetic diversity and longitude, latitude and elevation. We mapped the landscapes of genetic diversity and divergence for each species in GIS, and combined the resulting landscapes in order to identify hotspots of high genetic diversity and divergence.Results: There were no significant relationships between genetic diversity and longitude, latitude and elevation. For most species, areas characterized by high genetic diversity and divergence were located across the Hengduan Mountains. Nine evolutionary hotspots across the region of the QTP were identified. Main conclusions:The Hengduan Mountains are a remarkable hotspot of all three dimensions of biodiversity (genes, species and ecosystems), yet patterns of genetic diversity were partially incongruent with the distribution of species diversity. For example, several hotspots of genetic diversity were located on the QTP proper, which is relatively species poor. This partial geographic mismatch between species and genetic diversity highlights the need to consider both aspects in conservation programs. Our study suggests that more protected areas in the region of the QTP need to be established in order to protect genetic diversity and thus adaptive potential.
