    AFLP from two contrasting habitat types

    No full text
    We get these data from AFLP. In our study, we compare the genetic diversity and differentiation between two contrasting habitat types of Betula ermanii. Our results indicated that the two different type show different genetic structure. We presume that this species evolve under natural selection

    Effects of Surface Defects on Performance and Dynamics of CsPbI<sub>2</sub>Br Perovskite: First-Principles Nonadiabatic Molecular Dynamics Simulations

    No full text
    Inorganic mixed-halogen perovskites exhibit excellent photovoltaic properties and stability; yet, their photoelectric conversion efficiency is limited by inherent surface defects. In this work, we study the impact of defects on properties of CsPbI2Br slabs using first-principles calculations, focusing on specific defects such as I vacancy (VI), I interposition (Ii), and I substitution by Pb (PbI). Our findings reveal that these defects affect the geometric and optoelectronic properties as well as dynamics of charge carriers of slabs. We employ two theoretical frameworks (surface hopping and Redfield theory) of nonadiabatic molecular dynamics simulations to comprehensively study relaxation processes and obtain consistent results. The presence of VI reduces carrier lifetimes, while the influence of PbI on carrier lifetimes is negligible. In contrast, Ii defects lead to prolonged carrier lifetimes. These insights provide valuable guidance for the rational design of perovskite photovoltaic devices, aiming to enhance their efficiency and stability

    DataSheet_1_Contrasting patterns of genetic and phenotypic divergence of two sympatric congeners, Phragmites australis and P. hirsuta, in heterogeneous habitats.docx

    No full text
    Habitat heterogeneity leads to genome-wide differentiation and morphological and ecological differentiation, which will progress along the speciation continuum, eventually leading to speciation. Phragmites hirsuta and Phragmites australis are sympatric congeners that coexist in saline-alkaline meadow soil (SAS) and sandy soil (SS) habitats of the Songnen Meadow. The results provided genetic evidence for two separate species of reeds. Genetic diversity and spatial genetic structure supported the specialist-generalist variation hypothesis (SGVH) in these two sympatric reed species, suggesting that P. australis is a generalist and P. hirsuta is a habitat specialist. When we compared these different species with respect to phenotypic and genetic variation patterns in different habitats, we found that the phenotypic differentiation of P. australis between the two habitats was higher than that of P. hirsuta. Multiple subtle differences in morphology, genetic background, and habitat use collectively contribute to ecological success for similar congeners. This study provided evidence of the two reed congeners, which should contribute to their success in harsh environments.</p

    Figure S4. Effects of low N condition on the chlorophyll and carotenoid contents of synthetic hexaploid wheats (BBAADD genome), diploid wheat (DD genome) and tetraploid wheats (BBAA genome). Diploid wheat:TQ18; newly formed (synthetic) hexaploid wheats: AT5, Allo-960 and ELI 13; tetraploid wheats: 37A, ALTAR81, black bird, BOT and TTR04. The seedlings were subjected to low N condition (0.1 mM) for 31 days. The values are means of three biological replicates. Asterisks indicated significant difference (t test, P < 0.05) between control and low N-stressed plants for a given genotype. (TIF 1779 kb
