    Opis:
    Colonization of terrestrial ecosystems by the first land plants, and their subsequent expansion and diversification, were crucial for the life on the Earth. However, our understanding of these processes is still relatively poor. Recent intensification of studies on various plant organisms have identified the plant cell walls are those structures, which played a key role in adaptive processes during the evolution of land plants. Cell wall as a structure protecting protoplasts and showing a high structural plasticity was one of the primary subjects to changes, giving plants the new properties and capabilities, which undoubtedly contributed to the evolutionary success of land plants. In this paper, the current state of knowledge about some main components of the cell walls (cellulose, hemicelluloses, pectins and lignins) and their evolutionary alterations, as preadaptive features for the land colonization and the plant taxa diversification, is summarized. Some aspects related to the biosynthesis and modification of the cell wall components, with particular emphasis on the mechanism of transglycosylation, are also discussed. In addition, new surprising discoveries related to the composition of various cell walls, which change how we perceive their evolution, are presented, such as the presence of lignin in red algae or MLG (1→3),(1→4)-β-D-glucan in horsetails. Currently, several new and promising projects, regarding the cell wall, have started, deciphering its structure, composition and metabolism in the evolutionary context. That additional information will allow us to better understand the processes leading to the terrestrialization and the evolution of extant land plants.

    Opis:
    This pa per pres ents de vel op ment of the paleolake Starowlany ex ist ing in the Eemian Inter gla cial (MIS 5e) in north - east ern Po land. The lake his tory is based on Cladocera anal y sis. The paleolake Starowlany is lo cated in the cen tral part of the Sokó³ka Hills, ap prox i mately 9 km north of the town of Sokó³ka in the North Podlasie Low land. The sed i ments stud ied filled a south ern part of a tun nel val ley formed dur ing the Warta Gla ci ation. The cor ing was car ried out with a geo log i cal drill ing and con sti tuted a part of the frame work aimed at pre par ing the Sokó³ka sheet for the De tailed Geo - log i cal Map of Po land in scale 1:50 000. The core was 7 m long. Peaty silt, peats and or ganic silt were pres ent at the depth of 4.0–6.6 m, un der deluvial sands, tills and silt. Or ganic se ries was over lain by a clayey silt with no gla cial cover. Cladocera anal y sis was con ducted with 20 sam ples from a depth in ter val 6.6–4.1 m. Re mains of 17 spe cies of Cladocera were found, rep re sent ing the fam i lies: Chydoridae, Sididae and Bosminidae. A vast ma jor ity of them were the lit to ral spe cies. In the paleolake Starowlany four de vel op ment zones were dis tin guished that re flected changes as re gards tem per a ture, trophic lev els and changes of wa ter level in the lake. The paleolake ex isted from the early un til the mid dle Eemian. The high est wa ter level and the most fa vor able con di tions for zoo plank ton de vel op ment oc curred in zones SCZ I and II. The high est trophic level took place in SCZ III (mid dle Eemian). In the late Eemian the wa ter level dropped and the paleolake was trans formed into a wet land. At cer tain points, the higher wa ter level en abled ex is - tence of a few Cladocera spe cies. The rea sons for dis ap pear ance of the paleolake Starowlany in cluded a lo cal de crease in ground wa ter lev els as well as morphometric and geo log i cal char ac ter is tics of the lake.

    Opis:
    Our research confirmed the value of kettle-hole mires for reconstructing Holocene environmental changes. The multi-proxy approach in which three palaeoecological methods were used (analyses of testate amoebae, plant macrofossils and pollen) improved the interpretation potential. We studied two Sphagnum mires situated in Tuchola Pinewoods (N Poland). In Tuchola mire 9000 years of environmental changes (groundwater level and pH) were recorded. Water table changes inferred from Tuchola mire show patterns similar to regional hydrological changes recorded in Polish lakes and mires as well as in other European sites. Jelenia Wyspa mire recorded changes in local vegetation and palaeohydrology during the last 1500 years. A rise in the groundwater table, caused by deforestation in the catchment area, allowed Sphagnum to expand. Consequently, the peatland evolved into an oligotrophic mire dominated by peat mosses. Approx. 200 years ago water pH increased and subsequently decreased, the lowest value being associated with the deforestation maximum. Furthermore, the planting of pine probably also caused an acidification of Jelenia Wyspa mire.
