Abstract

The article provides results of palynological and algological analysis of peat deposits from MIS-5c in the Kiryas site. Sampling and analysis were carried out from the same horizon that was analyzed by other methods in already published works with the dating of the underlying layer at 105.5 ± 3.6 thousand years ago. Algological analysis and spore-pollen analysis were carried out. Three successive changes in vegetation were identified in the territories adjacent to the studied section. Changes in the composition of algal communities were used to trace changes in watering and the trophic status of the peat bog. Peat formation began with warming in time after 105 thousand years ago, with forest-tundra vegetation; in the second stage, a biome close to the modern northern taiga was formed; in the third stage, cooling occurred with the formation of a forest-tundra community and the end of peat formation. Complex conjugate analysis of stratigraphic records by various methods increases the reliability of reconstructions of natural changes. The abundance of algae remains allows us to conclude that the water level and the trophic status of the peat bog have changed.

根据古生物学和藻类学分析得出的基里亚斯-L 遗址晚更新世植物区系（俄罗斯西西伯利亚）

文章提供了对基里亚斯遗址 MIS-5c 泥炭沉积物的古植物学和藻类学分析结果。取样和分析是在同一地层进行的，该地层曾在已发表的著作中用其他方法进行过分析，底层的年代为距今 105.5 ± 3.6 千年。进行了藻类学分析和孢粉分析。在所研究地段的邻近地区发现了植被的三次连续变化。藻类群落组成的变化被用来追踪泥炭沼泽浇水和营养状况的变化。泥炭形成始于距今 10.5 万年之后的气候变暖时期，当时有森林-苔原植被；在第二阶段，形成了接近现代北部泰加林的生物群落；在第三阶段，气候变冷，形成了森林-苔原群落，泥炭形成结束。通过各种方法对地层记录进行复杂的共轭分析，可以提高重建自然变化的可靠性。藻类遗迹的丰富程度使我们可以得出结论，泥炭沼泽的水位和营养状态已经发生了变化。
