蜜蜂是主要的传粉类群,提供了一个关键的生态系统服务,许多被子植物依赖于成功的繁殖。现有数据表明,全世界的蜜蜂数量正在下降,但热带地区的数据不足,无法评估其状况和分布,对生态服务的影响,以及对管理行动的反应。在此,我们回顾了超过150篇论文,这些论文使用了六种常见的采样方法(盘式诱捕器,诱饵,Malaise诱捕器,扫网,定时观察和抽吸器),以更好地了解它们的优点和缺点,并帮助指导方法选择,以满足研究目标和多物种监测方法的发展。有几项研究评估了清扫网、捕集盘和不适捕集器的有效性,但只有一项研究评估了定时观察,没有一项研究评估了抽吸器。只有五项研究比较了其余四种抽样方法中的两种或两种以上。关于哪种方法对多个物种取样最可靠,几乎没有共识。然而,我们建议,如果研究的目的是估计丰度或物种丰富度,在开放的热带系统中,不适陷阱,盘陷阱和扫网是最有效的采样协议;相反,不适陷阱,网和诱饵可能是最有效的森林。蜜蜂数量的下降强调了方法标准化和报告精度的迫切需要。此外,我们建议报告一个可捕系数,衡量资源(蜜蜂)丰度和捕捞努力之间的相互作用。Melittologists还可以考虑现有的方法,如占用模型,以量化分布和丰度的变化后,建模的异质性诱捕概率,并考虑开发监测框架,从多个数据来源的可能性。
Bees are the predominant pollinating taxa, providing a critical ecosystem service upon which many angiosperms rely for successful reproduction. Available data suggests that bee populations worldwide are declining, but scarce data in tropical regions precludes assessing their status and distribution, impact on ecological services, and response to management actions. Herein, we reviewed >150 papers that used six common sampling methods (pan traps, baits, Malaise traps, sweep nets, timed observations and aspirators) to better understand their strengths and weaknesses, and help guide method selection to meet research objectives and development of multi-species monitoring approaches. Several studies evaluated the effectiveness of sweep nets, pan traps, and malaise traps, but only one evaluated timed observations, and none evaluated aspirators. Only five studies compared two or more of the remaining four sampling methods to each other. There was little consensus regarding which method would be most reliable for sampling multiple species. However, we recommend that if the objective of the study is to estimate abundance or species richness, malaise traps, pan traps and sweep nets are the most effective sampling protocols in open tropical systems; conversely, malaise traps, nets and baits may be the most effective in forests. Declining bee populations emphasize the critical need in method standardization and reporting precision. Moreover, we recommend reporting a catchability coefficient, a measure of the interaction between the resource (bee) abundance and catching effort. Melittologists could also consider existing methods, such as occupancy models, to quantify changes in distribution and abundance after modeling heterogeneity in trapping probability, and consider the possibility of developing monitoring frameworks that draw from multiple sources of data.
