    Evaluation of the current status and risks of aquatic ecology in the Jialing River Basin based on the characteristics and succession trends of phytoplankton communities by Maojin Huang, Fei Xu, Jia Xia, Xue Yang, Fubin Zhang, Siyao Liu, Tuo Zhang

    Published 2025-01-01
    “…The aquatic ecosystem health was better in autumn than in spring and in the mainstem than in the tributary. 3) Ammonia nitrogen and permanganate indices were key drivers of community composition in the tributary, while the main stem was negatively correlated with total phosphorus, ammonia nitrogen, and permanganate indices. 4) Stochastic processes dominated the assembly of phytoplankton communities in spring in the Jialing River, while autumn in the Jialing and Xichong Rivers (tributary river) and spring in the Xichong River were mainly dominated by deterministic processes. …”

    Published 2023-12-01
    “…The paper discusses the circumstances and technical solutions that contribute to the integration of electrical and thermal networks of urban neighborhoods within the framework of a surplus of electricity generating capacities arising from the imbalance in the development of energy generation and consumption, stochastic processes of market economy development, the transfer of energy-intensive industrial production to other countries, the desire to diversify fuel energy resources, passion for the construction of energy sources for alternative energy resources in counterbalance to traditional energy facilities without taking into account all aspects of the interaction of the former with the environment, etc. …”

    Similar biogeographic patterns of abundant and rare bacterial communities are driven by distinct assembly mechanisms in grassland soils by Sihao Zhu, Bai Yue, Kun Liu, Ning Zhao

    Published 2024-12-01
    “…Mean annual precipitation (MAP) was the dominant driver of community assembly at the transect scale, with extreme MAP (<200 or >400 mm) resulting in more deterministic processes and a moderate level of MAP (200–400 mm) leading to more stochastic processes. However, the effects of geographical distance and soil properties on different grassland habitats cannot be ignored. …”

    A novel framework unveiling the importance of heterogeneous selection and drift on the community structure of symbiotic microbial indicator taxa across altitudinal gradients in amp... by Jin Zhou, Zhidong Liu, Sishuo Wang, Jing Li, Lin Zhang, Ziyan Liao

    Published 2025-02-01
    “…In different altitude groups, we found that heterogeneous selection governed the community structure of symbiotic microbes across DSUs, while stochastic processes tended to increase with altitude. For DTUs at phylum and family levels, drift emerged as the dominant mechanism driving the community structure in the most symbiotic microbial taxa, while heterogeneous selection governs the most dominant or indicator taxa. …”

    Published 2025-02-01
    “…The empirical histograms for half-daily water level changes can be well-fitted by piecewise-exponential functions containing four or three sections, consistent with the understanding that level changes are deterministic rather than stochastic processes, as is well known in hydrology. Such statistical tests can serve as benchmarks for modeling water levels and discharges. …”

    Published 2025-02-01
    “…In comparison, S. alterniflora-associated bacterial communities were enriched with both sulfate-reducing bacteria (SEEP-SRB1) and sulfate-oxidizing bacteria (Sulfurimonas), which maintained a dynamic balance in the local sulfur-cycle, and thereby enhanced S. alterniflora growth. In addition, stochastic processes dominated the assembly of soil bacterial communities associated with all four plant species, but were most important for the S. alterniflora community. …”
