Elevational climatic gradients are powerful ecological model systems to understand drivers of biodiversity and possible impacts of climate change. However, rigorously designed studies taking into account the diversity, traits and phylogeny of multiple insect taxa, biotic interactions and environmental factors are lacking for most biogeographical regions. ANDIV3 will use a unique natural forest gradient from 250-3350 m elevation in southern Peru, a global biodiversity hotspot, to study diversity patterns and biotic interactions of bees and wasps. Field observation and experiments on species richness, abundance, morphological and physiological traits, and mutualistic and antagonistic biotic interactions of bees and wasps will be combined with intense (meta)barcoding of functional groups, stored pollen and arthropod prey. Bee and wasp diversity, plant-pollinator and host-antagonist interactions will be studied with transect observations, traps nests and pan traps during the dry and wet season on 30 study sites. In cooperation with ANDIV4 the hidden interactions of bees and wasps with microbial communities will be assessed. The results will allow to test general hypotheses on the role of bottom up resource limitation, top-down control and interactive effects of temperature and precipitation as drivers of biodiversity patterns. Together with the other three ANDIV projects on moth, dung insects and microbial communities this project will allow integrative data analyses to improve the understanding of drivers of holometabolous insect diversity, community assembly, traits and interaction networks. ANDIV3 will foster knowledge transfer and scientific training through close collaboration with Peruvian counterpartners.

海拔气候梯度是了解生物多样性驱动因素和气候变化可能影响的强大生态模型系统。然而，大多数生物地理区域缺乏考虑多种昆虫类群的多样性、特征和系统发育、生物相互作用和环境因素的严格设计的研究。ANDIV3将利用全球生物多样性热点地区秘鲁南部海拔250-3350米的独特天然森林梯度，研究蜜蜂和黄蜂的多样性模式和生物相互作用。对蜜蜂和黄蜂的物种丰富度、丰度、形态和生理特征、互拮生物相互作用等进行实地观察和实验，并结合对功能群、储存花粉和节肢动物猎物进行强（元）条形码分析。在干湿季节，将在30个研究地点通过样条观察、陷阱巢穴和平底陷阱研究蜜蜂和黄蜂的多样性、植物-传粉者和寄主-拮抗剂的相互作用。与ANDIV4合作，将评估蜜蜂和黄蜂与微生物群落的隐藏相互作用。这些结果将允许测试关于自下而上的资源限制、自上而下的控制以及温度和降水作为生物多样性模式驱动因素的相互作用的一般假设。该项目与其他三个ANDIV项目（蛾类、粪类昆虫和微生物群落）一起，将提供综合数据分析，以提高对全代谢昆虫多样性、群落聚集、性状和相互作用网络驱动因素的理解。该方案将通过与秘鲁伙伴的密切合作，促进知识转移和科学培训。
