Opis:
Palaeobotanical (mainly palynological) data from 38 sections of Lithuania and adjacent areas were used in order to resolve some palaeogeographical problems. The Butënai Interglacial (Holsteinian) had one distinct climatic optimum, represented by the B2–B4 pollen zones. This was a period of warm and wet climate with notable mild winters. The average annual temperature might have been 2–4ºC warmer and the annual precipitation some 300 mm greater than at present in Lithuania. There was probably no permanent snow cover during winters. Isopollen maps for the main forest constituents allow deduction of the directions of migration of individual tree taxa.

Opis:
A pollen sequence of Holsteinian/Mazovian age known since the 1980s in Brus (Western Polesie) is the second site with a plant macrofossil record in eastern Poland. High sedimentation rates in a palaeolake that functioned in this area have allowed a detailed climate reconstruction that enabled to trace the Older and Younger Holsteinian oscillations and to outline the water-level changes in the water body. Climate reconstructions, based on full palaeobotanical analyses (pollen and macroremains), were compared with those from Nowiny Żukowskie (Lublin Upland), revealing regional climatic patterns. The two Holsteinian climate oscillations were correlated with those detected in the Dethlingen section of Germany (Koutsodendris et al., 2010), providing more information on the spatial scale of these events.

Opis:
Lacustrine sediments representing Marine Isotope Stage 11 (MIS 11) were found in Hermanów (SE Poland) in a present-day closed depression under a thin cover of Weichselian and Holocene deposits (1.4 m). These sediments filled a palaeolake created as a result of melting of a dead-ice block at the end of MIS 12. Geological research has excluded the presence of an ice sheet during MIS 12 in this area. The lobe of the ice sheet of this glaciation was located several kilometres to the west of Hermanów. The palaeolake was part of a larger palaeolakeland in southeastern Poland, formed during MIS 11. The palaeomorphology of this interglacial is evident in the contemporary relief of the area and the outline of the lakes corresponds to the pattern of the closed palaeodepressions. Based on the record of sediments from Hermanów, a new perspective regarding the sub-division of MIS 11 is presented. Two regressive phases are observed in the Holsteinian Interglacial (MIS 11c) - OHO and YHO. The subsequent substages with five cold fluctuations according to the newest stratigraphic standards should be assigned to MIS 11b with a very clear cooling and a slightly warmer MIS 11a. Carbon isotopic composition of organic matter corroborates geological and environmental analysis. The isotopic composition suggests two cooling periods: OHO and MIS 11b. Stable climatic conditions with little temperature fluctuations persisted between the cooling periods.
