The spatiotemporal substitution method was used to collect yellow soil and purple soil with different acidification degrees;analyze the effects of acidification on the composition and properties of soil aggregates;explore the distribution characteristics，occurrence forms，and availability of arsenic（As）in soil aggregates with different acidification degrees;and reveal the key factors restricting the availability of soil As. The results showed that the distribution of total As in each aggregate was positively affected by its mass fraction，and the larger the mass fraction，the more the total As distribution. Soil acidification destroyed the aggregate structure，reduced the mass fraction of large aggregate S1（>2 mm）by 5 to 15 percentage points，led to the increase in amorphous iron content by 2 to 7 times，and decreased the total As distribution of S1. The available As was positively regulated by non-obligate/obligate adsorptive arsenic（F1，F2）（F1+F2 correlation coefficient 0.76）and negatively affected by residual arsenic（F5）（correlation coefficient −0.89）. Soil acidification significantly reduced the ratio of F1 to F2 after exogenous As entered the soil，resulting in a decrease in ω（available As）from 6.71-15.37 mg·kg−1 to 2.36-9.26 mg·kg−1，and the highest exogenous available As content was found in S1 and microaggregate S4（ © 2025 Science Press.

Animal adaptation to environmental challenges is a complex process involving intricate interactions between the host genotype and gut microbiome composition. The gut microbiome, highly responsive to external environmental factors, plays a crucial role in host adaptability and may facilitate local adaptation within species. Concurrently, the genetic background of host populations influences gut microbiome composition,highlighting the bidirectional relationship between host and microbiome. Despite this, our understanding of gut microbiome plasticity and its role in host adaptability remains limited, particularly in reptiles. To clarify this issue,we conducted a reciprocal translocation experiment with gravid females of the Qinghai toad-headed lizards(Phrynocephalus vlangalii) between high-altitude(2?600 m a.s.l.) and superhigh-altitude(3?600 m a.s.l.) environments on Dangjin Mountain of the Qinghai-Xizang Plateau,China. One year later, we assessed the phenotypes and gut microbiomes of their offspring. Results revealed significant plasticity in gut microbiome diversity and structure in response to contrasting elevations. Highaltitude conditions increased diversity, and maternal effects appeared to enable high-altitude lizards to maintain elevated diversity when exposed to superhigh-altitude environments. Additionally, superhigh-altitude lizards displayed distinct gut microbiome structures with notable host specificity, potentially linked to their lower growth rates. Overall, these findings underscore the importance of the gut microbiome in facilitating reptilian adaptation to rapid environmental changes across altitudinal ***, this study provides critical insights into microbial mechanisms underpinning local adaptation and adaptative plasticity, offering a foundation for future research on host-microbiome interactions in evolutionary and ecological contexts.

随着生活水平和消费水平的提高,人们对冷链物流配送需求与日俱增.同时,现实中的冷链物流公司往往需要同时承担多个运输任务.如何优化冷链物流配送路径,在保证客户满意度和冷藏品新鲜度的同时,降低多个配送任务各项成本,是当前急需解决的问题.鉴于此,首先构建包含车辆使用、油耗、碳排放、制冷、货损、时间窗惩罚成本以及客户满意度等约束的冷链物流配送模型;然后将多因子优化(MFO)信息共享框架与共生生物搜索(SOS)算法相结合,引入位置变换策略促进不同任务之间共享有效路径信息,提出基于位置变换策略的多任务共生生物搜索(PTMSOS)算法;最后将其用于求解多个冷链物流配送问题.仿真实验表明, PTMSOS算法不仅能够同时加快多个冷链物流配送问题的收敛速度,还能显著降低多个配送任务的各项成本.
