Abstract

Wild boar is an ecological engineer whose feeding activity can significantly influence the structure and composition of plant communities. The purpose of this study was to analyze the restoration of plant cover on wild boar rootings in areas recently colonized by wild boar in the north of Western Siberia compared to other parts of its range. The data were collected in four types of plant communities typical for the middle taiga subzone in Western Siberia. The rooting activity of wild boar led to a decrease in the projective cover and species richness of the herbaceous–dwarf-shrub and moss–lichen layers in the forest communities in the middle taiga of Western Siberia. The plant cover on the rootings was regenerated only by species that are typical of the original plant community. Unlike most other parts of the range of wild boar, in our study area we did not observe an increase in floristic species richness due to colonization or rootings by explerent plant species. This probably resulted from the initial low species richness of the northern plant communities.

西伯利亚中部针叶林野猪生根活性对植物群落的影响

摘要

野猪是一名生态工程师，其摄食活动会显着影响植物群落的结构和组成。这项研究的目的是分析西伯利亚西部北部最近被野猪殖民的地区与其野外其他部分相比，野猪根系上植物覆盖物的恢复情况。这些数据是在西伯利亚西部中针叶林次带典型的四种植物群落中收集的。野猪的生根活动导致西伯利亚中西部针叶林森林群落的草本覆盖层，矮灌木丛和苔藓地衣的投射覆盖度和物种丰富度下降。生根上的植物覆盖物仅通过原始植物群落的典型物种来再生。与野猪系列的其他大部分地区不同，在我们的研究区域中，我们没有观察到由于不同植物物种的定植或生根而导致植物物种丰富度的增加。这可能是由于北部植物群落最初的物种丰富度较低。
