    Coupling Bacterial Community Assembly to Microbial Metabolism across Soil Profiles by Lu Luan, Chao Liang, Lijun Chen, Haotian Wang, Qinsong Xu, Yuji Jiang, Bo Sun

    Published 2020-06-01
    “…The migration rate (m) and β-null deviation pattern supported the hypothesis of a relatively greater influence of dispersal in deep soil, which was correlated with bacterial community assembly by stochastic processes. These changes in the entire community assembly reflected consistent assembly processes of the two most dominant phyla, Acidobacteria and Chloroflexi. …”

    Regional biogeography versus intra-annual dynamics of the root and soil microbiome by Lukas P. Bell-Dereske, Gian Maria Niccolò Benucci, Pedro Beschoren da Costa, Gregory Bonito, Maren L. Friesen, Lisa K. Tiemann, Sarah E. Evans

    Published 2023-06-01
    “…Though all microbial communities were found to have significant spatiotemporal patterns, sampling site and collection date better explained bacterial than fungal community structure, which appeared more defined by stochastic processes. Root communities, especially bacterial, were more temporally structured than soil communities which were more spatially structured, both across and within sampling sites. …”

    Life Cycle Dynamics of a Key Marine Species Under Multiple Stressors by Saskia A. Otto, Susa Niiranen, Thorsten Blenckner, Maciej T. Tomczak, Bärbel Müller-Karulis, Gunta Rubene, Christian Möllmann

    Published 2020-05-01
    “…Our model integrates linear and non-linear responses to changes in life stage density, climate and predation pressure as well as stochastic processes. We use the integrated life cycle model to simulate copepod dynamics under a combination of stressor scenarios and to identify conditions under which population responses are potentially mitigated or magnified. …”

    Published 2022
    “…Deterministic processes predominated the community assembly regardless of AD ecosystem function, but stronger influences of stochastic processes were observed in dysfunctional AD ecosystems, which was likely attributable from the stronger effect of immigrants from the feedstock. …”

    Community organization and network complexity and stability: contrasting strategies of prokaryotic versus eukaryotic microbiomes in the Bohai Sea and Yellow Sea by Xiaoxiao Wang, Hualong Wang, Yantao Liang, Andrew McMinn, Min Wang

    Published 2024-09-01
    “…Abundant subgroups of prokaryotic/eukaryotic microbiomes exhibited greater environmental niche breadth and lower phylogenetic distance compared to the rare subgroups. Stochastic processes contributed greatly to microbiome dynamics, and deterministic processes governed the bacterioplankton organization with a lower phylogenetic turnover rate. …”

    Decadal changes in species composition of rare oak Quercus chungii forests with logging history by Wenbin Li, Xueer Zhong, Zhenji Li, Yonghui Huang, Xinfeng Chen, Lihan Huang, Ya Wang, Yuxin Chen

    Published 2024-12-01
    “…In this study, we assessed how species and phylogenetic composition of Q. chungii communities changed, and whether these temporal trajectories were primarily contributed by stochastic processes. We established two sites composed by Q. chungii adult trees in the nature reserve in 2013, and measured their species composition in 2013 and 2023, respectively. …”
