Understanding and managing pollination service is hindered by taxonomic impediments and paucity of data, particularly in the tropics. Herein we apply integrative species delineation and taxonomy to test impacts of land use on the diversity of bee communities within Xishuangbanna (Yunnan, south China), a highly biodiverse tropical region which has undergone extensive land conversion to rubber plantation. 128 Operational Taxonomic Units (OTU) were inferred by an iterative and integrative approach. Bee activity differed significantly across land use samples, although community composition corresponded more to level of vegetation density, when accounting for spatial structure. Species diversity was high in young rubber plantations, although composition overlapped with other species-rich habitats (natural forest edge and river banks), and older plantations (>8 years) showed very low diversity under all measures. Community structures were similar between the natural forest interior and edge, although analysis indicated contrasting drivers of diversity, with clustering in the interior and overdispersion in the forest edge. Further, phylogenetic diversity and derived indices were underestimated when reference data were omitted from analysis. The description of bee communities herein permits more informed choices in land management with respect to ensuring continuation of essential services by bees.
授粉服务的理解和管理受到分类学障碍和数据匮乏的阻碍，特别是在热带地区。在此，我们应用综合物种划定和分类学来检验土地利用对西双版纳（中国云南，热带地区）蜜蜂群落多样性的影响，该地区生物多样性极高，但经历了广泛的土地转化为橡胶种植园。通过迭代和综合的方法推断出 128 个操作分类单位（OTU）。尽管在考虑空间结构时，群落组成更符合植被密度水平，但蜜蜂的活动在不同土地利用样本中差异显著。在年轻的橡胶种植园中，物种多样性很高，尽管其组成与其他物种丰富的栖息地（自然森林边缘和河岸）重叠，但在所有措施下，超过 8 年的老种植园的多样性非常低。在自然森林内部和边缘之间，群落结构相似，尽管分析表明多样性的驱动因素不同，内部聚类，森林边缘过度分散。此外，当分析中省略参考数据时，系统发育多样性和衍生指数被低估。本文对蜜蜂群落的描述允许在土地管理方面做出更明智的选择，以确保蜜蜂继续提供必要的服务。
