入侵物种是生物多样性丧失的主要驱动因素之一。一些物种可以在新的栖息地建立并茁壮成长，影响当地社区，例如受管理的传粉媒介。在这方面，入侵物种随时间的扩张过程对其控制和管理至关重要。一个很好的例子是欧洲大黄蜂Bombus terrestris，自1997年以来，它被多次引入智利，用于作物授粉，并迅速入侵南美洲南部。通过编制2000 - 2019年阿根廷和智利562个发生点，对阿根廷和智利土地白刺虫入侵的时间动态进行了评估。我们使用两个估计器（最小凸多边形和95%固定核）来估计入侵面积随时间的增加。我们发现，在南美洲南部，B. terrestris入侵的面积随着时间的推移呈线性增加，这两种估计是一致的。在这种情况下，物种特征、环境特征和引进动态促进了快速入侵过程，并将继续扩大，在不久的将来到达其他南美国家。由于这种大黄蜂是一个超级多面手，正如气候生态位模型预测的那样，如果不采取行动，它可能会扩展到整个南美洲。
Invasive species are one of the main biodiversity loss drivers. Some species can establish and thrive in novel habitats, impacting local communities, as is the case of managed pollinators. In this regard, an invasive species' expansion process over time is critical for its control and management. A good example is the European bumblebee Bombus terrestris, which has rapidly invaded the southern part of South America after being repeatedly introduced in Chile for crop pollination since 1997. We assessed the temporal dynamics of B. terrestris invasion in Argentina and Chile by compiling 562 occurrence points from 2000 to 2019. We used two estimators (minimum convex polygon and 95% fixed kernel) to estimate the increase of the invaded area over time. We found that the area invaded by B. terrestris in the southern part of South America presents a linear increase over time, which was consistent for both estimators. In this scenario, species traits, environmental characteristics, and introduction dynamics facilitate a rapid invasion process that will continue to expand, reaching other South American countries in the near future. As this bumblebee is a super-generalist, it probably will expand across South America, as climate niche modelling predicts, if no actions were taken.
