摘要

Some Eurasian shrubs, including species of Lonicera, have become invasive in North America. Recently, Lonicera caerulea cultivars have been developed from Eurasian germplasm and promoted for North American markets as honeyberry, haskap, or sweetberryhoneysuckle. Checklist-based evaluation tools offer insight into the invasive potential of non-native plants introduced to North America, but can be difficult to utilize effectively for taxa with limited cultivation histories. The recent arrival of L. caerulea to North America's horticulture trade makes it difficult to answer questions that rely on an established history of ecological interactions in an introduced range. The only ecological observation that we have found in North America is a 2011 report of a naturalized woodland population of reproductive honeyberry shrubs in Minnesota. However, in northern Europe, the Norwegian Biodiversity Information Centre reported that Eurasian L. caerulea has spread rapidly from planted localities, and poses risks of severe impacts to Norway's natural plant communities. Our best interpretation of available data used in two risk-assessment tools developed for North America indicates that cultivars of Eurasian L. caerulea pose a high risk of invasiveness. A complicating factor is the native occurrence of the closely related mountain fly honeysuckle (Lonicera caerulea subsp. villosa (Michx.) . Love & D. Love] and blue fly honeysuckle [Lonicera caerulea subsp. cauriana (Fernald) B. Boivin] in portions of North America where cultivars of Eurasian L. caerulea have been promoted. Fly honeysuckles tend to be sporadic, small in stature, and not particularly productive; conversely, Eurasian cultivars have been hybridized and selected for rapid growth and high yield. Unanswered concerns include: 1) should L. caerulea germplasm from Eurasia be considered native in North America; 2) could hybrid, Eurasian genotypes of L. caerulea exhibit greater competitive fitness than the North American fly honeysuckles; and 3) will the introduction of Eurasian L. caerulea cultivars have population genetic consequences for indigenous fly honeysuckles.

Caerurea最近到达北美园艺贸易的到来使得难以回答依赖于引入范围内依赖既定生态互动史的问题。我们在北美发现的唯一生态观察是2011年在明尼苏达州的繁殖蜜羊灌木植入林地植物的综合林地植物报告。然而，在北欧，挪威生物多样性信息中心报道了欧亚人L. Caerulea迅速从种植的地方蔓延，对挪威的天然植物社区产生严重影响的风险。我们对为北美开发的两种风险评估工具中使用的可用数据的最佳解释表明欧亚人的栽培品种具有高风险的侵袭性。复杂因素是密切相关的山飞储藏金（Lonicera caerulea subsp的本地发生。villosa（Michx）。爱＆D.爱情]和蓝色飞储藏[Lonicera caerulea亚木。捕龙（Fernald）B. Boivin]部分北美欧亚L. Caerulea的品种促进了北美。飞储金往往是散发性，小的身材，而不是特别高效;相反，欧亚品种被杂交，选择快速增长和高产。未答复的担忧包括： 1）L.来自欧亚大陆的Caerulea种质是否被认为是北美的本土; 2）可以杂交，L. caerulea的欧亚基因型，比北美飞的金银花更多的竞争性; 3）欧亚人L. Caerulea品种的引入是否会有人口遗传后果对土着飞行金银花。
