Taxonomic compositions of chironomids and results of chironomid-based PCA of sediment core 11-CH-12 ...
We studied a sediment core from the lake Khatanga-12 (Taimyr Peninsula, Krasnoyarsk region). The core is 131.5 cm long and covers a period of sedimentation of 7100 years. In this study we made a chironomid analysis and a qualitative reconstruction of paleoecological development of the region and qua...
