    Spatial and Temporal Pervasiveness of Indigenous Settlement in Oak Landscapes of Southern New England, US, During the Late Holocene by Stephen J. Tulowiecki, Brice B. Hanberry, Marc D. Abrams

    Published 2025-03-01
    “…Results suggested that fire-tolerant vegetation, mainly oak (<i>Quercus</i> spp.), was more abundant near Indigenous settlements from 4955 to 205 YBP (i.e., 86–91% fire-tolerant trees), and significantly (<i>p</i> < 0.05) higher from 3205 to 205 YBP; fire-tolerant vegetation was less abundant away from settlements, where it also experienced greater fluctuations. Correlative models showed that warmer temperatures and distance to Indigenous settlement, which are both indicators of fire, were important predictors in the 17th–18th centuries of fire-tolerant tree abundance; soil variables were less important and their relationships with vegetation were unclear. …”

    On the propagation and interaction of the low-frequency ion-acoustic multi-solitons in a magnetoplasma having nonextensive electrons using Hirota bilinear method by Aljawhara H Almuqrin, Delmas V Douanla, Camus GL Tiofack, Alim, Alidou Mohamadou, Sherif ME Ismaeel, Samir A El-Tantawy

    Published 2025-09-01
    “…The reductive perturbation method is utilized to obtain the Korteweg-de Vries (KdV) equation for describing the low-frequency IAWs in proximity to critical values of the pertinent physical variables in the system. At specific essential plasma compositions, the modified KdV (mKdV) equation is derived for the parameter values at which the KdV model fails to analyze the nonlinear dynamics of the low-frequency IAWs adequately. …”

    Stochastic processes govern gut bacterial community assembly in a Schistosoma mansoni-transmitting snail, Biomphalaria straminea. by Zhanhong Yuan, Jinni Hong, Jehangir Khan, Jinghuang Lu, Benjamin Sanogo, Zhongdao Wu, Xi Sun, Datao Lin

    Published 2025-02-01
    “…This indicates that the interplay between stochastic and deterministic processes in the snail gut microbial assembly is associated with host fitness during snail adaptation to a new environment. Based on the null model analysis, we also found that stochastic processes (based on dispersal limitation, homogenizing dispersal, and undominated processes) play a larger role than deterministic (based on homogeneous selection and variable selection) in driving the snail gut bacterial community assembly. …”
