火灾会严重影响森林生态系统。然而,关于火灾对自然森林火灾后地块昆虫群落影响的研究很少。这项研究对火灾后2022年和2023年莫尔多维亚国家自然保护区(欧洲俄罗斯)森林中的鞘翅目动物区系进行了分析。在2010年和2021年从烧毁的地块(9)以及未烧毁的(对照)地块(2)中采样了昆虫,并比较了α多样性。材料加工后,我们共检查了来自38科的12,218个鞘翅目标本,鉴定了194个物种。Nitidulidae家族,天牛科,Elateridae,Scarabaeidae是所有地块中最丰富的。天牛科,Elateridae,Nitidulidae,葡萄球菌科,球藻科,和Scarabaeidae表现出最大的物种多样性。总的来说,在所有地块上都发现了17种,包括Cetoniaaurata,平菇,光亮体皮病,人鱼半翅目,Epuraeabiguttata,Glischrochilusgrandis,Glischrochilushortensis,四合格列希隆,Soroniagrisea,Pediacusdepressus,麻黄,Anastrangaliareyi,四面轻体,胸廓上叶,LepturaliaNigripes,Rhagiummordax,还有AnisandrusDispar.只有五个物种对某些地块表现出偏好。在未燃烧(对照)地块上观察到最大的丰度和物种多样性。2010年和2021年发生火灾的地块的鞘翅目总丰度值最低。这些大火摧毁了几乎所有潜在的甲虫定居地点,喂养,育种,和庇护所。与第二年相比,火灾发生后的第一年,陷阱记录的鞘翅目丰度更高。鞘翅目动物区系在对照地块上表现出最大的相似性。
Fires can significantly impact forest ecosystems. However, studies on the effects of fires on insect communities in post-fire plots in natural forests are rare. This study presents an analysis of the Coleoptera fauna in the forests of the Mordovia State Nature Reserve (European Russia) in 2022 and 2023 after a fire. Insects were sampled from burned plots (9) in 2010 and 2021, as well as unburned (control) plots (2), and alpha diversity was compared. After processing the material, we examined a total of 12,218 Coleoptera specimens from 38 families and identified 194 species. The families Nitidulidae, Cerambycidae, Elateridae, and Scarabaeidae were the most abundant across all plots. Cerambycidae, Elateridae, Nitidulidae, Staphylinidae, Coccinellidae, and Scarabaeidae exhibited the greatest species diversity. In total, 17 species were found on all plots, including Cetonia aurata, Protaetia cuprea volhyniensis, Trogoderma glabrum, Carpophilus hemipterus, Epuraea biguttata, Glischrochilus grandis, Glischrochilus hortensis, Glischrochilus quadripunctatus, Soronia grisea, Pediacus depressus, Chrysanthia geniculata, Anastrangalia reyi, Leptura quadrifasciata, Leptura thoracica, Lepturalia nigripes, Rhagium mordax, and Anisandrus dispar. Only five species exhibited preferences for certain plots. Maximum abundance and species diversity were observed on unburned (control) plots. The plots where fires occurred in 2010 and 2021 had the lowest total abundance values for Coleoptera. These fires destroyed almost all potential sites for beetle settlement, feeding, breeding, and shelter. Traps recorded a higher abundance of Coleoptera in the first year after fires compared to the second year. The Coleoptera fauna showed the greatest similarity on the control plots.
