Euglossine bees are an ecologically important group, which due to their diverse resource needs act as pollinators of many neotropical plants. Male euglossines collect fragrant compounds used in mating displays from diverse sources, including the flowers of orchids and other plants. This aspect of euglossine biology has proven exceptionally useful for studies of euglossine bee populations, because male bees can be readily attracted to fragrance baits deployed in natural habitats. We synthesise the data accumulated over the 50 years since the introduction of euglossine bee baiting inventories and make these data openly available in the EUGCOMM database. By fitting hierarchical joint species distribution models to presence-absence and abundance data, we reveal that the assemblages of bees attracted depend on the baits used in interaction with species-specific fragrance preferences and that bee assemblages are most diverse at sites in landscapes characterised by partial but not complete forest cover. We suggest that these results reflect the diverse resource needs of euglossine bees and are consistent with the hypothesis that male euglossines establish home ranges incorporating multiple habitat types. These results may have important consequences for the design of nature reserves in the tropics, if these iconic pollinators are to be conserved for the future.

在香味诱饵中收集到的 Euglossine 蜜蜂组合的数据库和合成

Euglossine 蜜蜂是一个生态上重要的群体,由于其多样化的资源需求,它们充当许多新热带植物的传粉者。雄性真光藻从多种来源收集用于交配展示的芳香化合物,包括兰花和其他植物的花朵。Euglossine 生物学的这一方面已被证明对研究 euglossine 蜜蜂种群非常有用,因为雄性蜜蜂很容易被部署在自然栖息地的香味诱饵所吸引。我们综合了自引入 euglossine 蜜蜂诱饵清单以来 50 年来积累的数据,并在 EUGCOMM 数据库中公开提供这些数据。通过将分层联合物种分布模型拟合到存在-不存在和丰度数据,我们发现,被吸引的蜜蜂组合取决于与特定物种的香味偏好相互作用所使用的诱饵,并且蜜蜂组合在以部分但不完全森林覆盖为特征的景观地点最为多样化。我们认为这些结果反映了 euglossine 蜜蜂的多样化资源需求,并且与雄性 euglossine 建立包含多种栖息地类型的家庭范围的假设一致。如果这些标志性传粉媒介要在未来得到保护,这些结果可能对热带自然保护区的设计产生重要影响。我们认为这些结果反映了 euglossine 蜜蜂的多样化资源需求,并且与雄性 euglossine 建立包含多种栖息地类型的家庭范围的假设一致。如果这些标志性传粉媒介要在未来得到保护,这些结果可能对热带自然保护区的设计产生重要影响。我们认为这些结果反映了 euglossine 蜜蜂的多样化资源需求,并且与雄性 euglossine 建立包含多种栖息地类型的家庭范围的假设一致。如果这些标志性传粉媒介要在未来得到保护,这些结果可能对热带自然保护区的设计产生重要影响。
