Abstract

Fire is increasingly used as a management tool in temperate deciduous forests, but the effects of fire on arthropods in these systems remain unclear. Here, we used flight-intercept traps to sample beetle assemblages (Coleoptera) in portions of a temperate deciduous forest of eastern North America subjected to either a higher-severity burn, a lower-severity burn, or no burn. We collected beetles immediately following the burns and for up to 2 yr post-burn. Average (±SE) beetle abundance did not differ between the higher-severity (45 ± 13) and lower-severity (55 ± 26) burns but was 2× higher in the burned sites vs. the unburned site (25 ± 6). Likewise, traps in the 2 burned sites captured a similar number of beetle species (17 ± 0.5 and 15 ± 0.5, respectively), and more species than in the unburned site (12 ± 0.4). These patterns were consistent over time post-burn in all sites. Beetle composition also consistently differed between the burned and unburned sites; bark and ambrosia beetles (Curculionidae: Scolytinae) were the most abundant groups in the burned sites. Species turnover (beta diversity) was highest in the unburned site. Eleven species were associated with specific combinations of burn treatment and time post-burn. The results suggest that fire severity and time post-burn play key roles in structuring local beetle assemblages and that longer fire intervals (≥3 yr) are required to facilitate recovery. Measuring beetle responses to fire in temperate deciduous forests improves our understanding of the effects of disturbance-based management on local biodiversity.

规定火灾烈度和燃烧后时间对温带落叶森林甲虫群落的影响。
在温带落叶森林中,火越来越多地被用作一种管理工具,但在这些系统中,火对节肢动物的影响尚不清楚。在这里,我们使用飞行拦截陷阱对北美东部温带落叶林中的甲虫组合(鞘翅目)进行了取样,这些甲虫分别遭受了较高程度的烧伤、较低程度的烧伤和没有烧伤。我们在烧伤后立即收集甲虫,并在烧伤后长达2年。重度烧伤(45±13)和轻度烧伤(55±26)的甲虫平均丰度(±SE)无显著差异,但烧伤部位的甲虫丰度(25±6)是未烧伤部位的2倍。2个烧毁点捕获的甲虫种类(分别为17±0.5种和15±0.5种)与未烧毁点捕获的甲虫种类(12±0.4种)相似,且数量较多。这些模式在烧伤后的所有地点都是一致的。甲虫的组成在燃烧点和未燃烧点之间也始终存在差异;树皮甲虫和凤头花甲虫是燃烧遗址中数量最多的类群。物种周转(β多样性)在未燃烧地最高。11种与烧伤治疗和烧伤后时间的特定组合有关。结果表明,火灾的严重程度和燃烧后的时间对当地甲虫组合的结构起关键作用,并且需要较长的火灾间隔(≥3年)才能促进恢复。测量温带落叶林中甲虫对火灾的反应有助于我们了解基于干扰的管理对当地生物多样性的影响。
