Богатыревичи 2

Spore-pollen analysis revealed the regional features of the vegetation communities forming. The percentages of all the AP and NAP taxa have been calculated of the total pollen sum AP+NAP (AP = pollen sum of trees and shrubs; NAP = pollen sum of upland herbs). The percentages of the pteridophytes and aquatics have been calculated of the total pollen sum. Indication of the pollen zones has been fulfilled according to the scheme of Makhnach et al. (1981) with some corrections based on more recent investigations.

DESCRIPTION OF THE POLLEN ZONES. MURAVIAN (=EEMIAN, MIKULINSKI) INTERGLACIAL

mr5 — Corylus-Tilia-Alnus

Arboreal species dominate while the herb plants are few. Synchronous maxima of Tilia and Alnus, preceded by the maximum of Corylus are characteristic of this zone. In most sections these events take place against a background of an increasing role of Carpinus. In Bogatyrevichi 1 and 2, increase of Polypodiaceae values and sporadic grains of Pinus, Betula, Ulmus were rec­ognized.

mr6 — Carpinus

The principal feature of this zone is the maximum of Carpinus, the presence of Picea and, increase of its percentage by the end of the zone. In Bogatyrevichi 1 and 2 a significant amount of Pinus and sporadic grains of Larix and Abies are registered at the end of the zone. The per­centages of Corylus and Tilia become lower.

mr7 — Pinus-Carpinus-Corylus I Pinus-Co-rylus-Quercus-Carpinus

This zone is characterized by the maximum of Pinus and by the second (small) peak of Carpinus. In Bogatyrevichi 1, Betula, Picea, Corylus and Alnus are present, Quercus, Tilia and Ulmus are rare, and the NAP values (Artemisia, Eri­caceae, Poaceae) are abundant. Sphagnum and Polypodiaceae prevail among spores.
