Abstract

The paper compares different approaches to the reconstruction of environmental conditions from rodent fossil complexes, namely, the bioclimatic method and the method of reconstructing soil and plant conditions considering voles. For the reconstruction, data from ten localities in Western Siberia dated to the second half of the Middle Pleistocene were analyzed. The bioclimatic method allowed us to reconstruct the arid climatic zone in the south of Western Siberia (the Pre-Altai Plain and the Middle Irtysh) and the moderately cold and arctic climate for the localities situated northwards. The method of reconstruction of soil and vegetation conditions showed the predominance of xerophytic plant communities for the southern localities and mesophytic, mesohygrophytic, and hygrophytic for the northern ones. As additional indicators of environmental conditions, specialized species were proposed: subterranean animals (Siberian zokor and northern mole voles) and briophages (West Siberian lemming).

基于啮齿动物化石区系重建鄂毕河和额尔齐斯河地区的环境条件

摘要

本文比较了从啮齿动物化石复合体重建环境条件的不同方法，即生物气候方法和考虑田鼠的土壤和植物条件重建方法。为了重建，分析了西西伯利亚十个地点的中更新世下半叶的数据。生物气候方法使我们能够重建西西伯利亚南部的干旱气候带（前阿尔泰平原和额尔齐斯河中部）以及北部地区的中冷和北极气候。土壤和植被条件重建方法显示，南方地区以旱生植物群落为主，北方地区以中生、中湿生和湿生植物群落为主。
