粪甲虫(鞘翅目:金龟子亚科(Scarabaeinae)介导许多生态功能,这些功能对维持陆地环境的生态系统功能至关重要。虽然大量的文献探讨了蜣螂介导的生态过程,很少有人知道的个别贡献,从不同的物种。在这里,我们的目的是检查内和种间的差异,粪埋葬率进行两个辊粪甲虫物种(Canthon smaragdulus Fabricius,1781年和Canthon sulcatus Castelnau,1840年)。此外,我们还评估了粪甲虫生物量与粪埋率之间的关系。我们设置了一个实验室实验,3个处理(2男,2女,和一对夫妇)和10个重复,每个处理的每种粪甲虫,和粪便埋藏率后,暴露100克混合猪和人的粪便48小时。我们的研究结果表明,粪便埋葬率的男性,女性和夫妇在每个物种没有不同。然而,C. smaragdulus个体的粪葬比C. sulcatus个人做的。此外,我们发现没有影响的个人生物量的粪便掩埋量的种内和种间水平。这些研究结果强调了需要进一步研究,考虑到不同的物种,即使来自同一属,可能会执行不同的生态过程,以及有关的重要性,考虑甲虫生物量时,测量其生态功能。我们呼吁开展研究,以填补关于单个物种对维持不同粪甲虫介导的生态过程的贡献的知识空白。
Dung beetles (Coleoptera: Scarabaeinae) mediate many ecological functions that are important to maintain the ecosystem functioning of terrestrial environments. Although a large amount of literature explores the dung beetle-mediated ecological processes, little is known about the individual contribution from distinct species. Here, we aimed to examine the intra and interspecific variations in dung burial rates performed by two roller dung beetle species (Canthon smaragdulus Fabricius, 1781 and Canthon sulcatus Castelnau, 1840). Furthermore, we evaluated the relationship between dung beetle biomass and dung burial rates. We set up a laboratorial experiment with three treatments (two males, two females, and a couple) and 10 replicates per treatment for each dung beetle species, and dung burial rates were measured after exposing 100 g of mixed pig and human excrement for 48 hours. Our results demonstrate that dung burial rates of males, females, and couples within each species do not differ. However, C. smaragdulus individuals performed a larger dung burial than C. sulcatus individuals did. In addition, we found no effect of individual biomass on the amount of dung burial on intra and interspecific levels. These findings highlight the need for further research considering that distinct species, even from the same genus, may perform different rates of ecological processes, as well as about the importance for considering the beetle biomass when measuring their ecological functions. We call for studies to fill in the knowledge gap about the individual species’ contribution to the maintenance of different dung beetle-mediated ecological processes.
