We measured abundance, diversity, and richness of Euglossa bees (Euglossini, Apidae) in lowland semi-deciduous forest in Darién National Park, Panamá, during the wet and dry seasons in the canopy and understory for five consecutive years (2013 to 2017) using McPhail traps baited with eucalyptus oil. We found a precipitous decline in abundance and richness throughout the 5 years of our study. Alpha diversity also declined throughout the study. Abundance, species richness and alpha diversity were significantly higher in the dry than in the wet season. There were no significant differences in the diversity, richness, or abundance between the canopy and understory. Our data contrast sharply with previous long-term studies of euglossine bees which showed stable populations.

巴拿马热带森林中本地蜜蜂(蜜蜂科:Euglossa)的衰退

我们连续五年(2013 年至 2017 年)测量了巴拿马达连国家公园低地半落叶林中桉树蜜蜂(Euglossini,Apidae)的丰度、多样性和丰富度,在树冠和林下的雨季和旱季期间用桉树油作为诱饵的麦克菲尔陷阱。在整个 5 年的研究中,我们发现丰度和丰富度急剧下降。在整个研究过程中,阿尔法多样性也有所下降。丰度、物种丰富度和 alpha 多样性在旱季明显高于雨季。冠层和林下层之间的多样性、丰富度或丰度没有显着差异。我们的数据与之前对 Euglossine 蜜蜂的长期研究形成鲜明对比,后者显示出稳定的种群。
