By applying several methods on the same material (if possible on the same core to avoid correlation problems), the uncertainties and weaknesses of single disciplines can be reduced. Case studies are summarized to illustrate three types of research questions: What were the qualitative changes in the Late Glacial? How large were the temperature changes quantitatively? and What were the biotic responses to an independently recorded temperature change? Plant macrofossils play an important role in answering these questions. When several biostratigraphies and isotope stratigraphies are combined in a multidisciplinary study, we may disentangle the changes in various ecological factors, such as temperature, effective moisture, salinity, pH, or nutrient availability.

The study is based on secular series of precipitation totals from 18 meteorological stations for the 138-year period from 1881 to 2018. Use is made of Fourier analysis (FFT) and wavelet transform nonlinear estimation. The study has found a 35-year Brückner cycle in annual precipitation across the area. The number of days during the year with the types of cyclonic circulation that lead to extremely high precipitation, i.e. with the northerly and north-easterly (Nc + NEc) types and a cyclonic trough (Bc), is not clearly correlated with the 35-year harmonic variability derived from annual precipitation totals. However, the Fourier transform demonstrates a local maximum at T = 35 years. A harmonic 6-month cycle has been discovered as the only harmonic cycle in monthly precipitation. Its stability over the 138-year timespan is investigated.

A set of 156 relevés was used in the null model analysis. Presence-absence date was taken into account. The results suggest that the species combinations found in the sample analyzed may be treated as random. In this respect, pleustonic assemblages from the Argentine correspond to those from Poland.

Most of the samples were dated with counter No. 3 (L3) filled to 1 or 2 atm pressure (Mościcki and Zastawny, 1977). Our counter No. 1 (L1) previously described (Mościcki and Zastawny, 1976) has been remounted and is now operating at 2 atm pressure of carbon dioxide. Samples measured with this counter have date numbers starting with Gd-1000. Parameters of proportional counters are listed in Table 1. Our transistorized electronics is being gradually replaced by more compact integrated-circuit electronics in CAMAC system (Bluszcz and Walanus, 1980). Counts from proportional counter and guard counters are recorded in 5 channels and punched every 100 minutes. Typical measurement of any sample, including background and oxalic acid samples, consists of a series of 20 to 25 partial measurements. Partial results obtained in such series are analyzed...

Measurements have continued with the same proportional counters, pretreatment procedures, carbon dioxide purification, measurement and calculation as described previously (Pazdur et al, 1982). Ages are reported as conventional radiocarbon dates in years before ad 1950. No corrections for 13C/12C ratio were made for samples reported in this date list. Infinite dates are based on a 2-sigma criterion (Pazdur and Walanus, 1979). Sample descriptions and comments are based on information provided by the submitters.

Isopollen maps clearly demonstrated, that all thermophilous trees, which appeared in this area in the early Eemian (Quercus, Ulmus, Fraxinus), migrated from the east or northeast. Also Tilia and Alnus, which arrived in the area of Poland in the middle part of the Eemian Interglacial migrated from the east. Picea, which colonized the territory of Poland twice: first at the very early stage of the interglacial, and then in the younger Eemian, migrated from the east and northeast. Only Corylus, Carpinus betulus and Abies alba migrated from other directions (from the south, from the southwest and from the southwest , respectively). Domination of the western and southwestern directions of migration routes clearly differentiates the Eemian Interglacial from the Holocene, during which the majority of trees and shrubs migrated into territory of Poland from the south, southeast , southwest and west, and only a few, such as Ulmus and Picea, also from the east and northeast. We assumed that the most probable reason of this difference was a presence of the Wartanian (Saalian) refugia of many trees, including thermophilous taxa, in the Eastern Europe (west Russia or Black See region). From those regions, together with the decay of the ice sheet, these trees migrated directly into Central Europe along the northern slopes of the Carpathians, or at first migrated to the north via regions which were beyond the maximum range of the Saalian, and from there to the west after the ice sheet melted in this part of Europe.

The result, however, produces little more than doubts. The standard Fourier analysis indicates some periods, namely 3.7-, 7.0-, 8.8-, and 17.5-year periods, and these periodic signals are distributed relatively consistently over some regions of Europe. However, the expectations that the exact harmonic 8.8 years of 17.5 years, and not so exact 3.7 years of 7.0 years will be present at the same or close stations are not fulfilled.
