Buzz-pollinated plants are an essential source of pollen for a significant portion of local bee communities. Buzz pollination research has focused on studying the properties of bee buzzes and their implications on pollen release, morphological specialization of flowers, and the reproductive ecology of buzz-pollinated plants. In contrast, diversity patterns and ecological interactions between bees and buzz-pollinated plants have been studied less. This study analyzed the buzzing bee community of twelve tropical buzz-pollinated co-occurring plant species in a tropical montane cloud forest during the flowering periods of two consecutive years, focusing on diversity, compositional similarity, structure, and specialization (H₂´) of the network. Twenty-one bee species belonging to Apidae, Colletidae, and Halictidae were recorded, fifteen species in 2014, and eighteen in 2015. Floral display and visited flowers doubled from first to second year, although the flowering period was 2 months longer in the first year. Bee compositional similarity between plants tended to be low; however, this was due rather to a high nestedness than species replacement. Temporal bee compositional similarity was also low but variable, and different plant species showed the highest similarity between years. The number of bee visits depended significantly on the number of flowers and years. Interactions between bees and plants showed a tendency to generalization. Compared to other buzz-pollinated networks, specialization (H₂´) was similar, but diversity was low and the network small. In endangered ecosystems like the Mexican cloud forest, however, buzzing bees support biodiversity and provide an essential ecological service by pollinating dominant understory flora.

蜂媒授粉植物是当地大部分蜜蜂群落的重要花粉来源。蜂鸣授粉研究的重点是研究蜜蜂蜂鸣的特性及其对花粉释放、花的形态特化和蜂授粉植物的生殖生态学的影响。相比之下，蜜蜂和蜂媒授粉植物之间的多样性模式和生态相互作用研究较少。本研究分析了热带山地云林连续两年开花期的十二种热带嗡嗡授粉共生植物物种的嗡嗡蜂群落，重点关注多样性、组成相似性、结构和专业化（H ₂ ´) 的网络。蜜蜂科、蜂蜂科和蜂蜂科共记录了 21 种蜜蜂，2014 年有 15 种，2015 年有 18 种。 从第一年到第二年，花卉展示和参观花卉翻了一番，尽管第一年的花期延长了 2 个月. 植物之间的蜜蜂组成相似性往往较低；然而，这是由于高度嵌套而不是物种替换。时间上的蜜蜂组成相似度也很低，但变化很大，不同的植物物种在年份之间表现出最高的相似度。蜜蜂访问的数量在很大程度上取决于花的数量和年份。蜜蜂和植物之间的相互作用表现出泛化的趋势。与其他嗡嗡声传粉的网络相比，专业化（H ₂ ´) 相似，但多样性较低且网络较小。然而，在墨西哥云雾林等濒临灭绝的生态系统中，嗡嗡的蜜蜂通过为主要的林下植物群授粉来支持生物多样性并提供必不可少的生态服务。
