Bee responses to anthropogenic disturbances have received much recent attention in scientific literature. These studies typically involve 1–3 years of sampling along spatial gradients of disturbance, though occasionally greater temporal replication and/or longer time periods are used at the expense of spatial replication. We surveyed bees using a blue vane trap during spring, summer and autumn from 2008 to 2017 at one location in Canberra, Australia. To the best of our knowledge, this is the longest near‐continuous record of bee activity in the southern hemisphere. We use these data to describe the temporal dynamics of the bee community, which was characterised by high annual variability in overall abundance, richness and composition and a negative correlation between spring rainfall and bee activity. The phenologies of abundant species are also described. Our findings relate only to our study site but are similar to findings from other long‐term studies conducted in the northern hemisphere, which collectively present a picture of high natural variability in bee communities that must be considered when interpreting findings of bee responses to anthropogenic disturbances.

澳洲东南部蜜蜂(膜翅目:Apoidea)群落10年期的物候

蜜蜂对人为干扰的反应最近在科学文献中引起了人们的注意。这些研究通常需要沿着扰动的空间梯度进行1-3年的采样,尽管偶尔会使用更大的时间复制和/或更长的时间间隔来牺牲空间复制。我们于2008年至2017年春季,夏季和秋季在澳大利亚堪培拉的一个地点使用蓝色叶片诱捕器对蜜蜂进行了调查。据我们所知,这是南半球蜜蜂活动的最长近连续记录。我们使用这些数据来描述蜜蜂群落的时空动态,其特征是总体丰度,丰富度和组成方面的年度高变异性以及春季降雨与蜜蜂活动之间的负相关性。还描述了丰富物种的物候。我们的发现仅与我们的研究地点有关,但与北半球进行的其他长期研究相似,这些研究共同呈现了蜜蜂群落中自然变异性高的情况,在解释蜜蜂对人为干扰的反应发现时必须考虑这些变异。
