Modern pollen spectra of the Teletskoye Lake shore: early results

Abstract

The article presents for the first time the results of an analysis of modern pollen spectra of the Teletskoye Lake shore sampled using 12 Tauber traps installed in various characteristic forest and meadow communities. Landscape descriptions have been performed for each sampling point, which increases the reliability of the interpretation of pollen spectra. Spectra are presented as a percentage of pollen from 27 identified taxa with a significant predominance of conifers, which are widespread in the composition of vegetation. Herb pollen is more diverse in the spectra compared to tree pollen but contributes less to their formation. The pollen of early flowering species is not represented in the spectra due to the late dates of trap installation. Based on the analysis, indicator taxa (Betula sect. Betula, Pinus sylvestris, Larix) marking the differentiation of natural conditions in the latitudinal and meridional parts of Lake Teletskoye were revealed mainly according to humidity regime.
