Bryophytes play important role in forest ecosystem functioning and their distribution and diversity are driven by numerous environmental factors. The aim of the present study was to bring new insights in deeper understanding of terrestrial bryophytes diversity in temperate forests, as well as to determine the environmental factors which have predominant influence on ground-floor bryophytes. The survey was conducted in Fruška Gora Mountain (Serbia) across seven forest sites where ground-bryophytes were sampled. Soil moisture, temperature, and pH were measured as soil characteristics, while herbaceous cover, litter cover, stream distance, number of trees and shrubs were used as characteristics of stand structure. Species richness, Shannon diversity index, and evenness index were used as diversity measures. Generalised linear model and canonical correspondence analysis (CCA) were used to test the influence of environmental variables on bryophyte diversity. Litter cover was the most important explanatory variable, followed by soil moisture, stream distance and tree number, respectively. Overall, the stand structure was found to have a greater impact on ground-floor bryophyte diversity compared to soil characteristics. Identification of the most significant ecological factors affecting the diversity and distribution of bryophytes in forest ecosystems is of great importance in forest ecology with the aim of defining adequate management methods to preserve the biodiversity of forests, with particular emphasis on endangered and rare bryophyte species.
苔藓植物在森林生态系统功能中起着重要作用，其分布和多样性受许多环境因素的驱动。本研究的目的是深入了解温带森林中陆生苔藓植物的多样性，并确定对地面苔藓植物有主要影响的环境因素。该调查在 Fruška Gora 山（塞尔维亚）的七个森林地点进行，在这些地点采集了地面苔藓植物。土壤水分、温度和 pH 值被测量为土壤特性，而草本覆盖、凋落物覆盖、溪流距离、树木和灌木的数量被用作林分结构的特征。物种丰富度、香农多样性指数和均匀度指数被用作多样性测度。广义线性模型和典范对应分析（CCA）被用于测试环境变量对苔藓植物多样性的影响。凋落物覆盖是最重要的解释变量，其次是土壤水分、溪流距离和树木数量。总的来说，与土壤特性相比，林分结构被发现对底层苔藓植物多样性有更大的影响。确定影响森林生态系统中苔藓植物多样性和分布的最重要生态因素，对于森林生态学具有重要意义，目的是确定适当的管理方法来保护森林的生物多样性，特别强调濒危和稀有苔藓物种。
