Alien plants, although usually rare in mountain habitats, can significantly impact native species diversity. The aim of this study was to analyse patterns of alien plant distribution in the Tatra Mts (Slovakia), focusing primarily on comparison of various transportation routes as a conduit for the spread of alien plants. We collected data on transects along: (i) railways, (ii) paved roads with unlimited access, (iii) tourist routes in mountain valleys (paved and unpaved roads, footpaths) with limited access and (iv) plots in areas surrounding mountain chalets. The majority of alien plants were found in locations at lower elevations and with intensive human activity. Patterns of distribution along the main corridors in the Tatras reflect the intensity and manner of use of each transportation route. Paved roads with unlimited access and railways are used most frequently and host the greatest number of alien species. Our observations show that the mode of access of these routes is more important than the road surface. Roads with limited vehicular access, be it unpaved and paved, are very similar in their alien species richness, while paved roads with limited and unlimited access significantly differ. Footpaths that cannot be accessed by vehicles are almost free of alien plants, even though they are found in the widest elevation range and often parallel to roads in the same valley. Other factors significantly negatively affiliated with alien species richness were elevation, cover of the tree and moss layer and moisture, and positively affiliated with the amount of nutrients.

影响塔特拉山外来植物分布的基础设施和其他环境因素的作用

外来植物虽然通常在山区栖息地很少见,但可以显着影响本地物种的多样性。本研究的目的是分析塔特拉山(斯洛伐克)的外来植物分布模式,主要侧重于比较作为外来植物传播渠道的各种运输路线。我们收集了沿线断面的数据:(i) 铁路,(ii) 无限制通行的铺砌道路,(iii) 访问受限的山谷中的旅游路线(铺砌和未铺砌的道路、人行道)以及 (iv) 山区小屋周围地区的地块. 大多数外来植物位于海拔较低且人类活动密集的地区。塔特拉山主要走廊沿线的分布模式反映了每条运输路线的强度和使用方式。无限制进入的铺砌道路和铁路使用最频繁,外来物种数量最多。我们的观察表明,这些路线的通行方式比路面更重要。车辆通行受限的道路,无论是未铺砌的还是铺砌的,其外来物种丰富度都非常相似,而通行受限和无限通行的铺砌道路则存在显着差异。车辆无法进入的人行道几乎没有外来植物,即使它们位于最宽的海拔范围内,并且通常与同一山谷中的道路平行。与外来物种丰富度呈显着负相关的其他因素是海拔、树​​木和苔藓层的覆盖度和水分,与养分含量呈正相关。我们的观察表明,这些路线的通行方式比路面更重要。车辆通行受限的道路,无论是未铺砌的还是铺砌的,其外来物种丰富度都非常相似,而通行受限和无限通行的铺砌道路则存在显着差异。车辆无法进入的人行道几乎没有外来植物,即使它们位于最宽的海拔范围内,并且通常与同一山谷中的道路平行。其他与外来物种丰富度显着负相关的因素是海拔、树​​木和苔藓层的覆盖度和水分,与养分量呈正相关。我们的观察表明,这些路线的通行方式比路面更重要。车辆通行受限的道路,无论是未铺砌的还是铺砌的,其外来物种丰富度都非常相似,而通行受限和无限通行的铺砌道路则存在显着差异。车辆无法进入的人行道几乎没有外来植物,即使它们位于最宽的海拔范围内,并且通常与同一山谷中的道路平行。其他与外来物种丰富度显着负相关的因素是海拔、树​​木和苔藓层的覆盖度和水分,与养分量呈正相关。它们的外来物种丰富度非常相似,而有限和无限进入的铺砌道路则大不相同。车辆无法进入的人行道几乎没有外来植物,即使它们位于最宽的海拔范围内,并且通常与同一山谷中的道路平行。其他与外来物种丰富度显着负相关的因素是海拔、树​​木和苔藓层的覆盖度和水分,与养分量呈正相关。它们的外来物种丰富度非常相似,而有限和无限进入的铺砌道路则大不相同。车辆无法进入的人行道几乎没有外来植物,即使它们位于最宽的海拔范围内,并且通常与同一山谷中的道路平行。其他与外来物种丰富度显着负相关的因素是海拔、树​​木和苔藓层的覆盖度和水分,与养分量呈正相关。
