We present the postglacial history of vegetation, human activities and changes in lake level context climate change northeast Poland from ~14,000 cal. b.p. to day. The palaeoecological reconstruction is based on results high-resolution plant macrofossil analyses as well records pollen, Cladocera radiocarbon dating. Climate fluctuations activity have caused many vegetation development Jezioro Linówek vicinity this lake. Early Holocene warming that occurred at ~9500 b.c. an increase Betula...

Abstract. Sedimentary charcoal records are widely used to reconstruct regional changes in fire regimes through time the geological past. Existing global compilations not geographically comprehensive and do provide consistent metadata for all sites. Furthermore, age models provided these harmonised many based on older calibrations of radiocarbon ages. These issues limit use existing research into past regimes. Here, we present an expanded database records, accompanied by new recalibration...
Cladocera are one of the most important freshwater biological indicators for a wide range environmental variables. They show strong responses to several factors (e.g., trophic state, water depth, temperature) and very sensitive changes in pH. The main interest this study was evaluate relationship between subfossil community composition properties dystrophic lakes (pH, transparency, conductivity, dissolved oxygen, depth area). We hypothesize that species depends on dystrophication index...
Environmental changes in Wigry Lake during the Late Glacial and Holocene were studied on basis of subfossil Cladocera analysis. are present a long core WZS/03 (Słupiańska Bay), surface sediments. The sediment contains remains twenty-seven species belonging to 5 families. Species composition plankton variability frequency specimens made possible distinguish five phases their development, which well correlated with palynological phases. correlation proves that biological development was...

Los datos obtenidos mostraron que sedimentacion lacustre IV comenzo periodo Glacial tardio continua...
High-altitude lakes are sensitive to modern and past climate changes. Given their low-water temperatures, alkalinity, nutrient levels, small climatic differences can strongly affect water chemistry, and/or biodiversity. In central Mexico, there only two high-altitude lakes, both within the crater of Nevado de Toluca volcano. Here, we present a paleolimnological record from one these lakes: La Luna. Previous paleoenvironmental work showed that it was Little Ice Age (LIA) cooling. Our results...
This study presents the results and interpretations of biological (floral faunal) geochemical (isotopic chemical element composition) investigations Late Glacial Holocene sediment accumulated in Kaniewo palaeolake. These data allowed us to determine indicators environmental changes this lake ecosystem, such as zooplankton vegetation development, trophic state, water temperature, level. We documented three cold periods (Oldest, Older, Younger Dryas) separated by two warm (Bølling, Allerød)....
Oxbow lakes are important habitats for many rare and protected wetland organisms play a role as storage of pollutants in floodplain. Unfortunately, oxbows were destroyed due to drainage works the adaptation riverbeds inland transport. Multi-proxy palaeoecological analyses makes it possible recognise succession flora fauna oxbow over centuries millenia. Insight into history wetlands ecosystems is especially their restoration. We used methods (plant macrofossils, pollen, mollusc, Cladocera,...
Cladoceran communities of two lakes Nevado de Toluca Volcano, Central Mexico, were studied. A new species Aloninae, Alona manueli sp. nov., is described. It was previously confused with Palearctic intermedia Sars, 1862, but clearly differs from it in the morphology postabdomen, head shield and pores, thoracic limbs. Position nov. within genus unclear, did not belong to any species-group s. lato. Other recorded studied are ossiani Sinev, 1998, Alonella pulchella Herrick, 1884, Chydorus...
<p>Cladocera species composition was analyzed in surface sediments of 29 lakes Central America (Guatemala, El Salvador and Honduras). The material studied collected with an Ekman grab autumn 2013 from located lowland, highland mountain regions. study revealed high variability qualitative quantitative subfossil Cladocera. A total 31 Cladocera (5 planktonic 26 littoral) were identified, as well 4 morphotypes that could not be identified (NRR<em> </em>1-4). Planktonic...
Cenotes (sinkholes), formed by the dissolution of carbonate rock, are most common waterbodies on Yucatan Peninsula. Despite their unique features and great amount in region, our knowledge biota cenotes remains fragmentary. Within present study we analysed chironomid from surface sediment ten situated SE Mexico. In total, 20 taxa 17 genera were recorded, total diversity was estimated to ~30 taxa. The Polypedilum (Tripodura) sp., Tanytarsus ortoni-type, Fittkauimyia Labrundinia sp....
The analysis of lake sediment cores have been long used as historical integrators environmental changes. Nutrient poor isoetid lakes remain under studied in the north boreal region. Hence, bottom sediments two Lobelia lakes, located NE Finland were analysed for presence Cladocera and Pediastrum remains. Sediment from littoral zones sampled, sectioned every centimetre aged with 210Pb. number taxa both identified was high, while individuals each taxon low. In Lake Kevojärvi, twenty five...
Abstract Cladocera (Crustacea: Branchiopoda) quickly respond to changes in environmental conditions and their remains are usually found large amounts lacustrine sediments, which make them an important biological proxy paleolimnological studies. Variations species composition have been used infer paleo-climate paleo-environmental variables including lake depth, eutrophication, deforestation. However, despite advantages as bioindicators the study of past conditions, they underutilized research...
Species composition of benthic and planktonic Cladocera was analysed in four lakes ponds located the southern part Spitsbergen Island near Fjord Hornsund. This is first study to provide information on species contemporary subfossil this region. A total eight taxa were found sediments waters that have been chosen for study. The included remains only five species, while seven zooplankton samples. results imply are subject natural transformations driven by fluctuating climate which reflected...
