我们探讨了使用生态位建模的数据汇编在一个参与性计划的数千名志愿者观察员，定量评估外来物种熊蜂的入侵的空间风险。B。自1991年以来，日本已将terrestris商业引入温室番茄作物授粉。最近，本种的归化种群迅速扩散，特别是在北方日本的北海道。两个基于生态位的模型从独立的数据集（存在-不存在和仅存在数据集）构建，并用于相互验证。这两个模型表现良好，并表明参与性计划编制的数据是有用的，用于生成这种入侵物种的潜在分布的预测模型。模型还揭示了B. terrestris与林地面积比例呈负相关，这与该物种的已知生物学相对应。与此相反，为番茄授粉引入的菌落数的效果（以番茄产量为代表）并没有显著影响B的分布。terrestris，表明其传播现在正进入一个阶段的扩散，从建立野生种群和主要扩散从商业殖民地在温室中不再是一个限制因素，这种入侵物种的分布。(C)2009爱思唯尔有限公司保留所有权利。
We explored the use of ecological niche-modeling from data compiled in a participatory program of thousands of volunteer observers to quantitatively evaluate the spatial risk of invasion by the alien species Bombus terrestris. B. terrestris has been commercially introduced to japan for the pollination of greenhouse tomato crops since 1991. Recently, naturalized populations of this species have spread rapidly, particularly in Hokkaido, northern Japan. Two niche-based models were constructed from independent data sets (presence-absence and presence-only data sets) and were used to validate one another. Both models performed well and indicated that the data compiled by participatory programs were useful for generating predictive models of the potential distribution of this invasive species. The models also revealed that the potential distribution of B. terrestris is negatively related to the proportion of woodland area, which corresponds to the known biology of this species. In contrast, the effect of the number of colonies introduced for tomato pollination (represented by tomato production) did not significantly affect the distribution of B. terrestris, indicating that its spread is now entering a phase of dispersal from established feral populations and that primary dispersal from commercial colonies in greenhouses is no longer a limiting factor for the distribution of this invasive species.
