Tropical forests are suffering several changes due to human activities. Among these, selective logging may represent a less damaging alternative, although it may alter species compositions of animals and plants in forest ecosystems. Dung beetles (Coleoptera: Scarabaeinae) are used as bioindicators as they respond quickly to environmental changes. Thus, in this study, we tested the effects of time after logging and seasonality on species richness, number of individuals, and assemblage structure of dung beetles in central Brazilian Amazon Forest. We also identified indicator species of logged and unlogged sites. We used a total of 240 flight interception traps (20 per area) in 11 logged sites (between one and 15 years after logging) and one unlogged site. We collected 28,508 dung beetles from 85 species. Most individuals (24,349, 85.41%) were collected during the dry period. Four species were good indicators of the unlogged site, while 21 species were indicators of logged sites. Time after logging and seasonality significantly affected species richness, the number of individuals collected, and assemblage structure. These effects were more significant from the second to the fifth year after logging. Logged sites represented 77% to 95% of species richness in the unlogged site. From the sixth year after logging, dung beetle assemblages were significantly recovered. Our results show that low-impact selective logging practices in sustainable forest sites may not cause irreversible impacts on dung beetle diversity.

由于人类活动，热带森林正在遭受多种变化。其中，选择性伐木可能是破坏性较小的替代方案，尽管它可能会改变森林生态系统中动植物的物种组成。粪甲虫（鞘翅目：Scarabaeinae）被用作生物指示剂，因为它们对环境变化反应迅速。因此，在这项研究中，我们测试了采伐后的时间和季节性对巴西中部亚马逊河森林中甲虫的物种丰富度，个体数量和组合结构的影响。我们还确定了已记录站点和未记录站点的指示符种类。我们在11个已记录站点（记录后1至15年之间）和1个未记录站点共使用了240个飞行拦截诱集装置（每个区域20个）。我们从85个物种中收集了28,508头甲虫。大多数人（24,349，85。在干燥期间收集了41％的水）。有4种是未记录地点的良好指标，而21种是已记录地点的指标。伐木后的时间和季节性显着影响物种的丰富性，采集的个体数量和组合结构。从采伐后的第二年到第五年，这些影响更为显着。伐木场占未伐木场物种丰富度的77％至95％。从伐木后的第六年开始，粪甲虫组合得到了显着恢复。我们的研究结果表明，在可持续森林场所进行的低影响选择性伐木做法可能不会对be虫的多样性造成不可逆转的影响。伐木后的时间和季节性显着影响物种的丰富性，采集的个体数量和组合结构。从采伐后的第二年到第五年，这些影响更为显着。伐木场占未伐木场物种丰富度的77％至95％。从伐木后的第六年开始，粪甲虫组合得到了显着恢复。我们的研究结果表明，在可持续森林场所进行的低影响选择性伐木做法可能不会对be虫的多样性造成不可逆转的影响。伐木后的时间和季节性显着影响物种的丰富性，采集的个体数量和组合结构。从采伐后的第二年到第五年，这些影响更为显着。伐木场占未伐木场物种丰富度的77％至95％。从伐木后的第六年开始，粪甲虫组合得到了显着恢复。我们的研究结果表明，在可持续森林场所进行的低影响选择性伐木做法可能不会对be虫的多样性造成不可逆转的影响。粪便甲虫组合得到了显着恢复。我们的研究结果表明，在可持续森林场所进行的低影响选择性伐木做法可能不会对be虫的多样性造成不可逆转的影响。粪便甲虫组合得到了显着恢复。我们的研究结果表明，在可持续森林场所进行的低影响选择性伐木做法可能不会对be虫的多样性造成不可逆转的影响。
