As so ci ate Ed i tor: Wojciech Granoszewski We de scribe the pen ul ti mate gla cial -last inter gla cial tran si tion from the one of the nu mer ous palaeolake suc ces sions in cen tral Po land, which have yielded many doc u mented Eemian and Early Weichselian flo ral re cords. In the new pro file, Parchliny 2016, the lac us trine de pos its were ana lysed lithologically, bo tani cally, zoo log i cally, and geochemically, pro vid ing new data that il lus trate the en vi ron men tal tran si tion from the Late Saalian (MIS 6a) to the Eemian inter gla cial (MIS 5e). Five phases of palaeolake de vel op ment have been dis tin guished. The first phase was re lated to the rapid melt ing of a dead ice block bur ied in the tills to form a lake. The sec ond phase doc u mented a Late Saalian ini tial suc ces sion, with the dom i nance of open steppe com mu ni ties (Stadial 1), fol lowed by a third phase with grad ual in creas ing den sity of veg e ta tion, the spread of bo real for ests (Zeifen interstadial) and fur ther in crease in open com mu ni ties and the re treat of pine (Kattegat stadial). The fourth phase re flected the be gin ning of Eemian inter gla cial by the ex pan sion of pi o neer ing birch-pine and purely birch for ests and an in creas ing pro por tion of de cid u ous trees, in clud ing oak (V th phase). Di a tom, cladoceran and geo chem i cal stud ies indi cate at least two stages of lake de vel op ment. The first stage (Late Saalian) was of an open lake (2-4 m deep), in rel a tively cold con di tions and nu tri ent-poor wa ter with the low est amounts of or ganic car bon and ni tro gen. The sec ond stage (Eemian inter gla cial), shows warmer, shal lower con di tions in which the lake's pri mary pro duc tion in creased, the wa ter was well ox ygen ated, and there were more trophic lev els.

“…The combination of selected geochemical (total organic carbon – TOC, total nitrogen – TN, TOC/TN) and isotopic data (δ 15 N, δ 13 C) obtained from OM with botanical proxies is used for paleoenvironmental reconstructions (e.g. Janbu et al, 2011; Kołaczek et al, 2015; Lauterbach et al, 2011; Niska and Mirosław-Grabowska, 2015).…”

During the Holocene, multiple thermal changes commonly occurred in the northern hemisphere. They are well-recorded in lakes with minimum human impact from the Arctic Circle area. The development of these lakes reflects ecological and climatic changes occurring from the formation of the lakes until present-day times. All environmental fluctuations affect biodiversity and are reflected in the number and composition of species. The goals of this study were to detect the ecological changes in a small Finnish lake using pollen, Cladocera and geochemical analyses. The research area is located within the northern zone of boreal coniferous forest and is the most sparsely populated region of Finland. The lake is located in Kuusamo uplands, E Finland, near the polar circle and over 20 km from the Russian border. Indicators of cold water were found only during the initial stage, after the 8.2 ka event and then the temperature was higher. Trophy was high at the beginning of the lake development and then a significant increase in trophy was found after 2600 BP. The impact of human activity is hardly traceable in Arctic Circle Finland throughout the Holocene Thermal Maximum. During the late-Holocene (after 4200 yr cal. BP), this impact is still weak and, even as late as the 20th century, only a few traces of human activity are recorded. General conclusion is that long-term climatic shift has been the most important factor driving changes in the limnology of Lake Talvilampi.

“…The coexistence of species characteristic of oligo-mesotrophic and eutrophic waters and the high share of Bosmina coregoni suggest a rather mesotrophic nature of the water body at that time. Thermophilic species such as Pleuroxus and Camptocerus rectirostris at the end of Alleröd, along with the cold-tolerant Eurycercus lamellatus [65], point to a moderately warm climate. In the transition to the Younger Dryas, the total number of Cladocera decreased, the number of ephippia increased, and cold-tolerant species such as Chydorus sphaericus and Alonella nana became dominant.…”

This article aims to trace in detail the periods of rapid changes during the Late Glacial period based on a subfossil Cladocera analysis and a palynological, geochemical, and statistical analysis. At the end of the Older Dryas, the water level in the reservoir was low, with quite cold waters and inconvenient conditions for developing Cladocera-dominated cold-tolerant species. The beginning of the Alleröd is marked by increasing vegetation density and a rising water temperature, with favorable conditions for developing rare species. At its end, there was a large diversity of species, along with the quite deep and rather mesotrophic nature of the water body. The beginning of the Younger Dryas is a shift back to conditions similar to those noticed during the Older Dryas. The shift to Holocene is manifested by a rapid increase in the number of species and abundance of planktonic forms that appeared before the Holocene onset. The high resolution of the research (1 cm sampling) allowed us to set up more precisely the boundaries between the stadials and interstadials of the Late Glacial and to find some species which were found in the sediment earlier than in previous studies.
