    Opis:
    The paleoecological research of biogenie sediments sampled in the different lake-mire ecosystems of the Łęczna Włodawa Lake District were the basis of studies on hydrological changes during the Late Glacial and Holocene. The lithological differentiation (spatial and temporal) of lacustrine and mire sediments in the studied sites indicates that the hydrological changes were of local nature. The investigations also evidence a specific functioning of the lakes in this region. Lake basins were formed as a result of the ground ice degradation and the transformation of groundwater circulation in the Late Glacial. The total area of lakes in the Lake District was the largest from the Younger Dryas to the Subboreal chronozone. The gradual lowering ofwater level during the early Holocene resulted in the transformation of sedimentation process, and in the development of typologically differentiated mires and lacustrinc-mire complexes.

    Opis:
    Veg e ta tion changes in the Lower San Val ley near Jaros³aw are re con structed from the Youn ger Dryas to the pres ent time on the ba sis of palynological anal y sis of the peat core. The pol len pro file came from a an old riverbed and was sup ple mented by ra dio car bon datings. The Youn ger Dryas and early Preboreal veg e ta tion was char ac ter ised by a high pro por tion of for est com mu ni ties with pine (Pinus sylvestris and P. cembra) and birch (Betula), while patches of open area were dom i nated by the steppe with Ar te mi sia. Cli ma tic ame lio ra tion dur ing the Preboreal chronozone led to the rapid spread of elm (Ulmus), which was prob a bly a dom i nant taxon on the low est ter races of the val ley. Terrestrialization of the wa ter body ex ist ing in the palaeomeaner and the sub se quent be gin ning of peat ac cu mu la tion caused a de - te ri o ra tion in pol len pres er va tion. Hence, the in ter pre ta tion of the pro file sec tion span ning the pe riod be tween the Bo - real and Subatlantic chronozones was se ri ously dis turbed due to se lec tive cor ro sion and the overrepresentation of Pinus sylvestris type and Filicales monolete sporomorphs. Be tween ca. 336 and 1152 AD fluc tu a tions in wood land cover were re corded. Im por tant com po nents in those for ests, de spite the dom i na tion of Pinus sylvestris, were Quercus, Carpinus betulus, Fagus sylvatica and Abies alba. The first pol len grains of ce re als (Cerealia type) were found be fore ca. 1605–1414 BC and may be at trib uted to the ag ri cul tural ac tiv ity of the Neo lithic and/or early Bronze tribes. Pe ri - ods of strong de for es ta tion caused by hu mans were prob a bly re lated to the time when the Tarnobrzeska Group of the Lusatian Cul ture and the Przeworska Cul ture were ac tive. The first groups of Slavs did not sig nif i cantly in flu ence the en vi ron ment, but the sub se quent de vel op ment of those groups led to more vis i ble de for es ta tion, which was trig gered af ter the es tab lish ment of Jaros³aw in the 11th cen tury AD.

At the cur rent stage of re search, the age of the stud ied de pos its was de ter mined by AMS radio car bon dat ing of few sam ples only. This meant that the chro nol ogy of the in ves ti gated pro files had to be es ti mated also in di rectly us ing their palynological cor re la tion with a ra dio met ri cally well-dated pro file from Lake Wigry. The ob tained pol len data con firmed the pic ture of the postglacial veg e ta tion changes of the Wigry Na tional Park, which was based on ear lier stud ies of Lake Wigry. Fur ther more, it doc u mented the ex is tence, mainly in the Preboreal and At - lan tic chronozones, of tem po rary changes in veg e ta tion, which might be a re ac tion to a short-lived cold fluc tu a tions of cli mate.

    Opis:
    The Vistulian decline was a period of rapid environmental events. The authors correlated ages of the last Scandinavian Ice Sheet limits in northern Poland with ages of prominent events adapting the conditions of periglacial environment of Central Poland in response to the Late Vistulian climate warming. Ages from previous thematic geological and palaeogeographical studies were collected. The approach used indicates that despite methodological uncertainties and sometimes inconsistency of ages, it is especially helpful in timing of first warming signals (ca. 19–18 cal ka BP) and establishing of environmentally bipartite 3 millennia of the Oldest Dryas in the extraglacial zone. Abrupt warming at the onset of the Bølling-Allerød is well registered in biotic and abiotic archives available from Central Poland and remains in agreement with the large recession of the southern ice sheet margin.
