Opis:
The Lubuskie Lake Dis trict played an im por tant part in recolonisation of the Pol ish Plain due to its lo ca tion and the char ac ter of the ter rain. De spite that, it is and es pe cially its north ern part, poorly ex plored re gard ing both his tory of Late Gla cial and early Ho lo cene set tle ments, and the nat u ral en vi ron ment. The pa per pres ents re sults of multidisciplinary re search in this area. The most spec tac u lar dis cov er ies were con nected with re mains of set tle ments of the Hamburgian cul ture so ci et ies at Myszêcin – cur rently the rich est site of this cul ture over the en tire North Eu ro pean Plain. In the vi cin ity of this site sev eral Late Palaeo lithic and Mesolithic set tle ments of var ied func tions were re corded. First palynological re cords came from the Youn ger Dryas sed i ments in this area. In a log with a palynological spec trum com pris ing Youn ger Dryas and the be gin ning of the Ho lo cene, a char coal dust was found and it could in di cate hu man ac tiv ity as hu mans lived at a lake shore. An im por tant com ple ment to the im age of the Late Gla cial set tle ment at the Lubuskie Lake Dis trict was pro vided by the re search near Lubrza that re sulted in data re gard ing set tle ments of the Federmesser and OEwiderian cul ture so ci et ies. This re gion was not typ i cal in a palynological spec trum of de pos its dur -ing AllerÝd but also in di cated highly di ver si fied thick ness of basal peat in a small area.

Opis:
This pa per fo cuses on the use ful ness of a palaeolimnological method called the joint algological and zoo log i cal anal ysis. The joint algo-zoo log i cal anal y sis in volves count ing all iden ti fi able re mains of the main al gae groups (Bacillariophyta, Cyanophyta, Desmidiales, other Chlorophyta, Trachelomonas sp.) and in ver te brate groups (Cladocera, Ostracoda, Chironomidae, Chaoborus sp., and other in sects, Turbellaria, Bryozoa, Spongia and Testacida) in vol u met ric sam ples. We pres ent re sults from re cent sed i ments of Lake Glubokoe (Mos cow re gion, Rus sia) as an ex am ple of the ap pli ca tion of this method. We re con struct the struc ture of phytoplankton, zoo plank ton and zoobenthos com mu ni ties and their dy nam ics over the last 25 years. Our re sults sup port the va lid ity of this method in the re con struc tion of the struc ture of phyto- and zoo plank ton com mu ni ties and their dy nam ics, in for ma tion that may be lost when car ry ing out sep a rate anal y ses for in di vid ual groups. Sim plic ity is an other ad van tage of this meth od ol ogy.

Opis:
The main phases of the Late Gla cial and Ho lo cene de vel op ment of veg e ta tion in the Wigry Na tional Park were re con - structed based on the pol len anal y sis of sed i ments from three small dystrophic lakes (Lake Suchar Wielki, Lake Suchar II and Lake OElepe). 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.

Dis appear ance of ha zel around 1200 cal. years BC, ac com pa nied by ex pan sion of horn beam has been ob served and should be linked with ac tiv ity of the Z¹bie-Szestno type cul ture and the Lusatian cul ture tribes dur ing the Bronze Age, but not with a cli mate change. Con sid er able in ten si fi ca tion of set tle ment pro cesses re corded in the youn ger part of the Subatlantic chronozone was one of the im por tant rea sons that were re spon si ble for quick changes in for est struc ture. Strong and con tin ued de for es ta tion started as early as the end of the 10th cen tury AD and was sub stan tially in ten si fied in the first half of the 13th cen tury.
