摘要

气候变化和人类影响正在改变山区生态系统,对物种分布和生物多样性产生重大影响。在这些变化中,低地物种向山区的上移尤为突出。本研究考察了沿喀尔巴阡山脉海拔梯度分布的三个白头翁物种的生态位重叠和遗传多样性:低地白头翁(4x)、山地白头翁(2x)和高山白头翁(2x)。通过使用 SNP 分析对 600 多个个体进行基因分型,然后进行主坐标分析(PCoA)、邻接网络分析和结构聚类分析,我们不仅发现了不同的遗传群体,而且还发现了所有物种之间的杂交,这表明存在三系杂交的可能性。环境背景和生态位重叠分析进一步证实了基因掺杂,这些分析表明物种之间存在大量重叠,尤其是在垂直分布方面。气候包络图显示,由于气候变化,山区物种的可用栖息地可能会减少,从而导致竞争加剧和杂交加剧。人类活动的影响进一步加剧了这些杂交趋势。在所研究的物种中,L. gaudinii面临的杂交风险最大,而L. ircutianum则可能经历栖息地扩张。通过提供全面的遗传和生态概述,我们的研究强调了杂交在生物多样性保护中的重要性,以及山区环境变化和人类活动带来的挑战。这项研究不仅有助于了解喀尔巴阡山脉的遗传多样性,还强调了分子生态学和山区生态系统保护策略的广泛意义。

Genetic Diversity and Ecogeographical Niche Overlap Among Hybridising Ox-Eye Daisies (Leucanthemum, Asteraceae) in the Carpathian Mountains: The Impact of Anthropogenic Disturbances.

Climate change and human influence are transforming mountain ecosystems, significantly impacting species distributions and biodiversity. Among these changes, the upward migration of lowland species into mountain regions stands out. This study examines the ecogeographical niche overlap and genetic diversity among three Leucanthemum species distributed along an altitudinal gradient in the Carpathian Mountains: the lowland L. ircutianum (4x), the montane L. rotundifolium (2x) and the alpine L. gaudinii (2x). By genotyping over 600 individuals using SNP analysis, followed by principal coordinate analysis (PCoA), Neighbour-Net Network and Structure clustering, we reveal not just distinct genetic groups but also hybridisation across all species, suggesting the potential for triple hybrids. Genetic admixture is further supported by environmental background and niche overlap analyses that reveal substantial overlap among species, particularly in line with their vertical distribution. Climate envelope plots indicate a likely reduction in available habitat for mountainous species due to climate change, leading to an increase in competition and an intensification of hybridisation. Anthropogenic influences are further intensifying these hybridisation trends. Among the studied species, L. gaudinii is most at risk of overwhelming hybridisation, whereas L. ircutianum may experience habitat expansion. By providing a comprehensive genetic and ecological overview, our research highlights the significance of hybridisation in biodiversity conservation and the challenges posed by environmental changes and anthropogenic activities in mountain environments. This study not only contributes to the understanding of genetic diversity in the Carpathians but also underscores the broader implications for molecular ecology and conservation strategies in mountain ecosystems.

期刊介绍: Molecular Ecology publishes papers that utilize molecular genetic techniques to address consequential questions in ecology, evolution, behaviour and conservation. Studies may employ neutral markers for inference about ecological and evolutionary processes or examine ecologically important genes and their products directly. We discourage papers that are primarily descriptive and are relevant only to the taxon being studied. Papers reporting on molecular marker development, molecular diagnostics, barcoding, or DNA taxonomy, or technical methods should be re-directed to our sister journal, Molecular Ecology Resources. Likewise, papers with a strongly applied focus should be submitted to Evolutionary Applications. Research areas of interest to Molecular Ecology include: * population structure and phylogeography * reproductive strategies * relatedness and kin selection * sex allocation * population genetic theory * analytical methods development * conservation genetics * speciation genetics * microbial biodiversity * evolutionary dynamics of QTLs * ecological interactions * molecular adaptation and environmental genomics * impact of genetically modified organisms
