摘要

维管植物(VP)和苔藓植物(B)是森林生物多样性的重要组成部分,它们对森林内的管理强度和自然干扰均有响应。在这项研究中,我们在斯洛文尼亚广泛的可持续管理森林中调查了林下VP和B在多样性和组成水平上的跨分类群一致性。对所选植物类群的分类和功能特征进行了研究,重点研究了地栖植物。我们采用基于特征的方法来研究功能特征。平均而言,在可持续经营的温带森林中,B的物种丰富度随VP数量的增加而增加。此外,研究类群之间的物种组成也存在适度的正相关。土栖VP和B在性状组成上是一致的,受土壤反应、养分和光有效性的影响,而在对水分的响应上则略有相似。耐压VP的组成与B血红蛋白呈负相关,表明森林环境受干扰程度较低。这可能是由于斯洛文尼亚森林的可持续管理,近年来气候变化和自然干扰加剧。两类群在分类学多样性与组成和性状多样性与组成4个不同层次上的跨分类比较显示出不同程度的一致性。因此,必须从不同方面监测这两个群体的状况和时间趋势,以得出可靠的结论。

Congruence between vascular plants and bryophytes in response to ecological conditions in sustainably managed temperate forests (taxonomic- and trait-based levels)
Abstract Vascular plant species (VP) and bryophytes (B) constitute a significant portion of forest biodiversity and respond to both management intensity and natural disturbances within forests. In this study, we investigated the cross-taxa congruence between understorey VP and B at both diversity and composition levels across a wide range of sustainably managed forests in Slovenia. The taxonomic and functional characteristics of the selected plant groups were studied, with a particular emphasis on ground-dwelling species. We employed a trait-based approach to examine the functional characteristics. On average, the species richness of B in sustainably managed temperate forests increased with the corresponding number of VP. Furthermore, a moderate positive correlation in species composition between the studied groups of ground-dwelling organisms was also observed. The ground-dwelling VP and B were congruent in terms of trait-based composition, which was influenced by soil reaction and nutrients and light availability, while trait-based diversity was only slightly similar in response to moisture. A negative correlation between the composition of stress-tolerant VP and B hemeroby was found, indicating forest environments with a low level of disturbance. This is likely due to the sustainable management of Slovenian forests, where climate change and natural disturbances have intensified in recent years. A cross-taxon comparison of the two groups at four different levels, namely taxonomic-based diversity and composition and trait-based diversity and composition, revealed varying degrees of congruence. It is therefore important to monitor the status and temporal trends of both groups from different aspects to draw reliable conclusions.
