外来入侵植物的日益蔓延改变了全世界的生物多样性。迄今为止，该领域的研究主要集中在入侵植物物种如何影响授粉媒介行为，但缺乏关于外来植物物种对野生授粉媒介种群影响的数据。自 19 世纪引入并在 20 世纪 50 年代后迅速传播以来，外来黄花（加拿大一枝黄花、一枝黄花）一直是欧洲最成功的入侵植物物种之一。我们研究了黄花对波兰东南部野生传粉昆虫群落的影响。比较了黄花入侵湿草甸（10条样线）和未入侵对照湿草甸（10条样线）之间野生蜜蜂、食蚜蝇和蝴蝶的丰度、物种丰富度和多样性。此外，我们还比较了两组地点之间的植物多样性和平均覆盖度。一枝黄花的入侵对野生传粉媒介的多样性和丰度产生了非常强烈的负面影响。植物多样性和平均覆盖度也受到黄花入侵的负面影响。野生传粉昆虫根据其筑巢和食物专长进行分组，但没有一种能够抵抗入侵，这表明引入的黄花可能会影响整个野生传粉昆虫群落。我们的研究强调，迫切需要为受到外来植物威胁的栖息地中的野生授粉媒介制定具体的保护计划，我们呼吁不仅在波兰，而且在整个大陆范围内引入阻止黄花入侵的计划。 (C) 2009 Elsevier Ltd. 保留所有权利。
The increasing spread of invasive alien plants has changed biodiversity throughout the world. To date research in this area has focused on how invasive plant species affect pollinator behaviour, but there is a lack of data on the impact that alien plant species have on wild pollinator populations. Since their introduction in the 19th century, and rapid spread after the 1950s, alien goldenrods (Solidago canadensis, Solidago gigantea) have been among the most successful invasive plant species in Europe. We studied the effects of goldenrods on wild pollinator communities in SE Poland. The abundance, species richness and diversity of wild bees, hoverflies and butterflies were compared between wet meadows invaded by goldenrod (10 transects) and non-invaded controls (10 transects). Furthermore, we compared the plant diversity and average cover between the two groups of sites. Invasion of goldenrods had a very strong negative effect on wild pollinator diversity as well as abundance. Plant diversity and average cover were also negatively affected by goldenrod invasion. Wild pollinators were grouped according to their nesting and food specialization, but none were resistant to the invasion, indicating that introduced goldenrod may affect the entire wild pollinator community. Our study emphasises the urgent need to develop specific protection plans for wild pollinators in habitats threatened by foreign plants and we call for the introduction of programs to stop the invasion of goldenrod not only in Poland, but also on a continental scale.
