Ma jor changes in the in ver te brate com mu ni ties oc curred ca. 400 AD on wards when the lit to ral cladoceran Alonella nana started to re place the plank tonic Eubosmina as the dom i nant spe cies and chi rono mids Psectrocladius sordidellus group and Zalutschia zalutschicola in creased. These changes were most likely due to a de creas ing wa ter level and an en larg ing pro por tion of the lit to ral area, pro vid ing suit able veg e ta tive hab i tats, e.g. aquatic bryophytes (mosses), for these taxa. The low er ing wa ter level reached its min i mum just be fore the Me di eval Warm Pe riod, ca. 800–1000 AD, af ter which the lake level rose again and re mained high un til mod ern times.

Opis:: Late Holocene deposits containing abundant and well-preserved malacofauna were exposed within the Spa Park in Busko-Zdrój. Molluscan shells were found in sand, dark muds and calcareous muds. Dark and calcareous muds are intercalated by fine-grained sand and peat devoid of malacofauna. Ali these deposits were accumulated on swampy, flat bottom of wide river valley. The result of radiocarbon dating has shown that the formation of the deposits started in the upper part of the Subboreal Phase. Numerous Late Medieval portery shards were found in several topmost profile sections. The identified malacofauna suggests that similar climatic and habitat conditions prevailed throughout the entire sedimentation period. Snails typical of open habitats, accompanied by hygrophilous taxa, play a dominant role. Mesophilous and aquatic taxa occur in accessory proportions, while shadow-loving forms are virtually absent.

Opis:: The Falsztyński valley, in the eastern part of Podhale, Poland includes a low terrace spanning the stream channel, the structure of which has been studied in nine profiles. Five gravel levels and five mud levels with plant and abundant mollusc remains are described, temporally constrained by ten radiocarbon dates. The terrace deposits represent the terminal part of the Atlantic Phase and all of the Late Holocene. The mollusc analysis helped identify phases of environmental change, notably one in the Middle Ages connected with intensive settlement activities in the area of Podhale. These include deforestation, affecting mollusc communities with replacement of forest assemblages by open-country species. The gravel levels records increased fluvial activity periods correlated with humid climate phases. It is possible to distinguish five such periods corresponding to the transition of the Atlantic and Subboreal phases, the middle part of the Subboreal Phase, the transition of the Subboreal and Subatlantic phases, the younger part of the Subatlantic Phase, and the last 200 years. These correspond to the periods of increased fluvial activity in the valleys of other Carpathian rivers.

Opis:: Several tufa complexes are known in the Slovak Karst which is a typical karst area of a temperate climate. This area is built of Mesozoic carbonates, mainly Triassic in age. The karst systems drain carbonate plateaux and lead water to resurgences located in valleys which are up to 300 m deep. Below the resurgences there are Holocene fossil tufa deposits that exceed 12 m in thickness. The tufas include stromatolite, moss, phytoclastic, oncoidal, and intraclastic facies. Extensive barrages which once dammed the upper reaches of the streams were formed in narrow valleys. They are composed predominantly of moss facies and stromatolites, with subordinate oncoidal and phytoclastic facies. Phytoclastic, oncoidal and intraclastic facies are dominant in dammed segments of streams, and include gastropod shells and charcoal fragments. Some small moss cushions are also developed. Barrages and dammed areas formed in a longitudinal fluvial depositional system. Conversely, below resurgences located on plateau slopes tufas of a perched springline depositional system were formed. These comprise deposits of prograding cascades constructed by moss, phytoclastic and stromatolitic facies. Presently, the tufas analysed are inactive. They stopped growing in the Late Holocene time, after which there was abrupt incision of the streams. This caused downcutting into Holocene tufas, in some places reaching Mesozoic bedrock. At present tufa is being precipitated from streams in all the sites studied.

Opis:: The Vistula Lagoon is situated along the south-eastern shore of the Gulf of Gdańsk and is linked with the gulf through the Strait of Baltiysk. Separated from the open sea by the Vistula Spit, the Vistula Lagoon is a shallow body of water with a mean depth of 3 m; the bottom is covered with a layer of mud several metres thick. This article presents a unique, newly discovered locality of tree stumps occurring in situ at the bottom of the Vistula Lagoon. The radiocarbon age of the alder stumps and the top of the peat in which they are rooted is Subboreal. The alder wood was dated to 4770±35 and 3295±35 years BP. The top layers of peat were dated to 4670±40, 4410±35 and 3690±35 years BP. The considerable scatter of the dates indicates the significance of erosional processes during marine transgressions. Radiocarbon dates and pollen analyses indicate that in the late Atlantic – early Subboreal periods, the water level of the Vistula Lagoon was about 3 m lower than it is today. The −2 m level was passed no earlier than c. 3500 years ago; the −1 m level was reached around 2000 years ago.

Opis:: This study combines high-resolution planktonic foraminiferal eco-biostratigraphy and palaeoclimatic data from the high-sedimentation-rate core J PC-26 from the northwestern margin of the Gulf of Mexico (GoM). The eco-biozones recognized (GOMPFE1-12) being correlated with published Mg/Ca-based sea surface temperatures. This updated palaeoclimatic and stratigraphic reference record facilitates correlations with the Greenland ice core events and their climatic relationships, and also provides a solid stratigraphic framework for correlations with other palaeoclimatic and palaeoceanographic records in the circum-GOM/Caribbean region. This multidisciplinary approach underlines the utility of supporting conventional dating methodologies with different constraints, and further reveals a powerful tool for reliably correlating marine records between comparable deep-sea marginal settings and coeval sequences of this region.

Opis:: The glacial history of the Svalbard archipelago is often a hot topic for researches, but the articles usually refer to a particular piece of Svalbard. The authors of this work studied many scientific articles based on the researches to find and collect this history.Svalbard archipelago is located in the Arctic, at the edge of the continental shelf of Europe. The end of shelf boundary noted occurrence of ice caps in the past glaciations. In turn, the main elements of the landscape of the archipelago are glaciers that are currently in a recession. Spitsbergen (the biggest island of the archipelago) sets the limit of Pleistocene glaciations, and the current state of glaciers allows determining the place where the recession is intense.The main aim of the authors in this study is to show this history only from the late Vistulian to the late Holocene (the beginning of 21st century). Interstadials and Stadials start time varies, as their duration in different places, according to various authors. It is very hard to collect all information and describe this history. By knowing the history of glaciation, we can distinguish in the late Vistulian: Last Glacial Maximum (LGM), Bølling/Older Dryas/Allerød and Younger Dryas (YD). LGM was the stadial in which was the maximum extent of ice sheet in late Vistulian. After this period, ice sheet began to retreat from the continental shelf. In turn, YD was the stadial in which the last advance of glaciers took place, about 11 000 years BC. In the Holocene we can distinguish Holocene Climatic Optimum (in the meantime short Cooling Holocene), Revdalen Stadial, Medieval Warm Period, Little Ice Age (LIA) and 20th century warming. The maximum extent of glaciers in Holocene was in LIA. In LIA, the extent of glaciers was bigger than in YD. In 20th century a warming started and continues until now.
Svalbard jest obszarem, gdzie zachowały się w różnym stopniu „ślady” zdarzeń glacjalnych. Dowodami ich wystąpienia są między innymi osady oraz formy glacjalne i fluwioglacjalne (np. Boulton 1979; Boulton i in. 1982; Landvik i in. 1998; Mangerud i in. 1998; Pękala, Repelewska-Pękalowa 1990; Lindner, Marks 1993ab; Ingólfsson, Landvik 2013). Bliskość tego obszaru w stosunku do centrów zlodowaceń powodowała, że kolejne epizody glacjalne „zamazywały ślady” poprzednich, niszcząc je lub przekształcając (np. Landvik i in. 1992; Mangerud i in. 1998; Zagórski 2007). Po deglacjacji następował zazwyczaj okres intensyfikacji działania procesów nieglacjalnych (paraglacjalnych), np. morskich, peryglacjalnych (Mercier, Laffly 2005; Strzelecki 2011; Zagórski i in. 2012). Stąd najlepiej zachowały się pozostałości najmłodszych zdarzeń i epizodów glacjalnych, np. małej epoki lodowej (np. Baranowski 1977abc; Lindner Marks 1993b; Werner 1993; Wójcik, Ziaja 1999; Reder 1996ab; Birkenmajer, Łuczkowska 1997; Svendsen Mangerud 1997; Zagórski i in. 2008, 2012; Rodzik i in. 2013).

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.
