    Genetic diversity and structure analyses of largemouth bass (Micropterus salmoides) original and cultured populations based on microsatellite markers by SU Shengyan, ZHANG Linbing, LI Haiyang, GAO Can, HE Xinjin, TIAN Can, LI Jianlin, WANG Meiyao, TANG Yongkai

    Published 2020-12-01
    “…For the two-phased model of mutation (TPM), both WILCOXON and sign tests showed that California population was in a status of mutation-drift disequilibrium. For population structure, it was found by analysis of molecular variance (AMOVA) that 15.57% of the genetic variation came from among populations, 25.05% from within populations, and 59.38% from among individuals (P<0.01). …”

    Genetic diversity and population structure of parasite infrapopulations within and across hosts for two trophically transmitted trematode parasites by Sarah R. Goodnight, April M.H. Blakeslee, Michael W. McCoy

    Published 2025-04-01
    “…Thus, we expect that first-intermediate host dynamics and dispersal ability played a large role in predicting population-level parasite genetic diversity and genetic structure in this system. This study investigates the effects of small- and large-scale processes on parasite genetic population structure and diversity and provides critical genetic data for future studies on these genera.…”

    Local Forest Structure and Host Specificity Influence Liana Community Composition in a Moist Central African Forest by Begüm Kaçamak, Maxime Réjou‐Méchain, Nick Rowe, Vivien Rossi, Nicolas Barbier, Samantha Bazan, Eric Forni, Daniel Guibal, David J. Harris, Grace Jopaul Loubota Panzou, Jean‐Joël Loumeto, Eric Marcon, Bruno X. Pinho, Isaac Zombo, Sylvie Gourlet‐Fleury

    Published 2025-03-01
    “…ABSTRACT Lianas are important components of tropical forest diversity and dynamics, yet little is known about the drivers of their community structure and composition. Combining extensive field and LiDAR data, we investigated the influence of local topography, forest structure, and tree composition on liana community structure, and their floristic and functional composition, in a moist forest in northern Republic of Congo. …”

    Evolution characteristics of overburden structure in inclined fully mechanized caving under residual coal pillars of the upper layer by LIU Yong, WANG Hongwei, WU Xuesong, TIAN Chengpeng, GUAN Rongfu, NIE Yunxiao, FAN Zhiwei, CAO Peipei

    Published 2024-12-01
    “…The results showed that the mining of the lower fully mechanized caving face induced instability in residual coal pillars of the upper layer, resulting in large-scale overburden collapse. The roof structure within the disturbed zone evolved progressively into a composite structure of "low-level inverted step cantilever beams and high-level large masonry beams". …”
