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.

The nu mer ous dystrophic (humic) lakes are a very im por tant fea ture of Wigry Na tional Park, NE Po land. As the most re cent palaeo eco logi cal data in di cate, at the be gin ning of its de vel op ment (in the Late Gla cial and Early and Mid dle Ho lo cene) these wa ter bod ies func tioned as har mo ni ous lakes, and their trans for ma tion into dystrophic lakes and the sta bi li za tion of the trophic state took place at the be gin ning of the Subboreal. Palynological anal y sis of sed i ments from two such lakes (Lake OElepe and Lake Suchar II), with spe cial em pha sis on non-pol len palynomorphs (NPPs), was aimed at a de tailed bi o log i cal char ac ter iza tion of dystrophic lakes dur ing their long-last ing ex is tence. The ob tained re - sults al lowed for the des ig na tion of or gan isms char ac ter is tic for dystrophic lakes, of which rep re sen ta tives ap peared with the de creas ing pH of the wa ter and the for ma tion of Sphag num peat around lakes. These or gan isms were di vided into four groups: al gae, fungi, tes tate amoe bas, and an i mals. Their rep re sen ta tives ap pear in var i ous de vel op men tal stages of dystrophic lakes.

The re sults of pol len, non-pol len palynomorph and microcharcoal par ti cle anal y ses of de pos its from a small pond in north east ern Po land are pre sented. The study fo cused on hu man-in duced veg e ta tion changes that oc curred in a close vi cin ity of the set tle ment com plex at Poganowo dur ing the Mid dle Ages (ca 10th–16th cen tu ries). We dis tin guished three phases of hu man im pact. First and third phases cor re spond to in ten si fied set tle ment ac tiv ity. The sec ond phase was a pe riod when hu man ac tiv ity de creased and wood land re gen er a tion took place. The high in ci dence of the par a - sitic fun gus Kretzschmaria deusta in a lo cal for est stand dur ing the third phase was si mul ta neous with nu mer ous spores of coprophilous fungi (Sordaria-type and Cercophora-type). We con sider that Kretzschmaria deusta in hab ited the roots and bases of tree trunks dam aged by dig ging and graz ing an i mals.

Sig nif i cant spread - ing of sec ond ary semi-nat u ral birch for est, de vel op ment of horn beam for est and in creas ing im por tance of anthropogenic open com mu ni ties were the most char ac ter is tic fea tures of veg e ta tion evo lu tion.
