Abstract

The species composition and the general characteristics of the fauna of phytophagous beetles (superfamilies Chrysomeloidea and Curculionoidea) on the Sterlitamak shikhans are considered based on original material. The shikhans Tratau, Kushtau, and Yuraktau are cone-shaped relict limestone mountains that are unique natural objects located near Sterlitamak in the Republic of Bashkortostan. The shikhans reveal an extremely high total species diversity of leaf beetles and weevils, comprising 327 species from 8 families, or no less than 25% of the entire faunas of these groups in the forest-steppe belt of the Volga Region and the Cis-Urals. Of the three shikhans, the fauna of Tratau with 283 species is the richest and the most specific. Among the zonal complexes, the group of phytophagous beetles of steppe ecosystems is the most diverse on the shikhans, comprising 297 species, or 90% of the species recorded. The arealogical and ecological analyses have shown that the shikhan faunas have a fairly original structure characterized by pronounced participation of both Western and Central Palaearctic species, many of which are located there at the meridional limits or within the insular parts of their ranges. The studied faunas have a large proportion of petrophilic steppe and desert-steppe forms and include many relict faunal elements of different origins. Most of the relicts are concentrated in petrophytic steppes, screes, and rock outcrops of the shikhans, some of them being trophically associated with relict and/or endemic plant species. Stephanocleonus ignobilis, Pseudocleonus dauricus, and Ceutorhynchus subpilosus are known in Bashkortostan only from the shikhans; it is suggested that these relict species should be included in the regional Red Data Book. In addition, two apparently flightless and probably new species of flea beetles from the genera Phyllotrera Chevr. and Longitarsus Berth. were found on Tratau. The forest ecosystems contain a sufficiently rich group of nemoral species associated with the European oak; these species occur in Bashkortostan at or near their eastern range limits. The data presented clearly show that the fauna and communities of phytophagous beetles of the Sterlitamak shikhans are highly original, reflecting the uniqueness of their natural complexes as a whole and providing a very important argument against industrial development of any of the shikhans.

摘要

根据原始材料，考虑了Sterlitamak shikhans上的噬食性甲虫（超科Chrysomeloidea和Curculionoidea）的种类组成和动物区系的一般特征。希克汉族的Tratau，Kushtau和Yuraktau是圆锥形的遗迹石灰岩山脉，是位于巴什科尔托斯坦共和国Sterlitamak附近的独特自然物体。锡克汉族人揭示了叶甲虫和象鼻虫的极高物种总数，包括来自8个科的327种，占伏尔加河地区和顺乌拉尔地区森林草原带中这些动物群总数的25％以上。在这三种shikhans中，Tratau的动物区系最丰富，最具体，共有283种。在纬向复合体中，草原生态系统的植物食性甲虫种类在shikhans上最为丰富，包括297种或90％的已记录物种。区域学和生态学分析表明，shikhan动物群具有相当原始的结构，其特征是西部和中古古北种的明显参与，其中许多位于子午线界限或其范围的岛内。所研究的动物群具有较大的嗜湿草原和荒漠草原形式，并包括许多不同来源的遗留动物群元素。大多数遗物集中在石羊汉的石化草原，熨平板和岩石露头上，其中一些与遗物和/或特有植物物种营养相关。区域学和生态学分析表明，shikhan动物群具有相当原始的结构，其特征是西部和中古古北种的明显参与，其中许多位于子午线界限或其范围的岛内。所研究的动物群具有较大的嗜湿草原和荒漠草原形式，并包括许多不同来源的遗留动物群元素。大多数遗物集中在石羊汉的石化草原，熨平板和岩石露头上，其中一些与遗物和/或特有植物物种营养相关。区域学和生态学分析表明，shikhan动物群具有相当原始的结构，其特征是西部和中古古北种的明显参与，其中许多位于子午线界限或其范围的岛内。所研究的动物群具有较大的嗜湿草原和荒漠草原形式，并包括许多不同来源的遗留动物群元素。大多数遗物集中在石羊汉的石化草原，熨平板和岩石露头上，其中一些与遗物和/或特有植物物种营养相关。所研究的动物群具有较大的嗜湿草原和荒漠草原形式，并包括许多不同来源的遗留动物群元素。大多数遗物集中在石羊汉的石化草原，熨平板和岩石露头上，其中一些与遗物和/或特有植物物种营养相关。所研究的动物群具有较大的嗜湿草原和荒漠草原形式，并包括许多不同来源的遗留动物群元素。大多数遗物集中在石羊汉的石化草原，熨平板和岩石露头上，其中一些与遗物和/或特有植物物种营养相关。在巴什科尔托斯坦共和国，仅从希克汉族人就知道无脊椎动物Stephanocleonus ignobilis，Pseudocleonus dauricus和Ceutorhynchus subpilosus。建议将这些遗迹物种列入区域红色数据手册。另外，来自Phyllotrera Chevr属的两种显然不能飞行的跳蚤甲虫。和Longitarsus泊位。在Tratau被发现。森林生态系统包含与欧洲橡树相关的足够丰富的nemoral种。这些物种出现在巴什科尔托斯坦共和国东部范围或附近的范围。所提供的数据清楚地表明，Sterlitamak shikhans的植物噬食性甲虫的动物群和群落是高度原始的，反映了其天然复合物整体的独特性，并为反对任何shikhans的工业发展提供了非常重要的依据。
