    Patterns of association of native and exotic boring polychaetes on the southeastern Pacific coast of Chile: the combined importance of negative, positive and random interactions by Paula E. Neill, Nicolás Rozbaczylo, Cristóbal Villaseñor-Parada, Garen Guzmán-Rendón, Sandra Sampértegui, Cristián E. Hernández

    Published 2020-04-01
    “…Nevertheless, the large number of random interactions observed indicates that species coexistence can be accounted for by stochastic processes, as proposed by neutral theory. Coexistence may be a frequent result of interactions between native and exotic species, although less apparent than competitive exclusion. …”

    Spatial scale affects the relative role of stochasticity versus determinism in soil bacterial communities in wheat fields across the North China Plain by Yu Shi, Yuntao Li, Xingjia Xiang, Ruibo Sun, Teng Yang, Dan He, Kaoping Zhang, Yingying Ni, Yong-Guan Zhu, Jonathan M. Adams, Haiyan Chu

    Published 2018-02-01
    “…Conclusions Our findings revealed that (1) stochastic processes are relatively more important on the North China Plain, while deterministic processes are more important on the Tibetan Plateau; (2) soil pH was the major factor in shaping soil bacterial community structure of the North China Plain; and (3) most variation in soil microbial community composition could not be explained with existing environmental and spatial factors. …”

    Asymptotics, exact results, and analogies in p-adic random matrix theory by Van Peski, Roger

    Published 2023
    “…This generalizes the explicit formula for the classical Cohen-Lenstra measure on abelian p-groups. (5) We give an exact sampling algorithm for products of corners of Haar GLₙ(Zₚ)-distributed matrices, and show by analyzing it that the singular numbers of such products obey a law of large numbers and their fluctuations converge dynamically to independent Brownian motions. (6) We classify left GLₙ(Qₚ)-invariant stochastic processes on the (discrete) homogeneous space GLₙ(Qₚ)/GLₙ(Zₚ) with independent increments. …”
