Palaeoecological evidence of the Scandinavian Ice Sheet retreat during the last glaciation in north-eastern Poland (Suwałki Lake District)
Two chironomid-inferred mean July air temperature reconstructions in the South Carpathian Mountains over the last 2000 years
We present chironomid-based reconstructions of mean July air temperature changes over the last 2000 years from Lake Latoriței (1530 m a.s.l.) in the Southern Carpathians. A multi-proxy analysis was performed along a 58 cm long sediment core and two training sets were used for quantitative July air temperature reconstructions: the Eastern-European (EE, 212 lakes) and the Finnish-Polish-Carpathian (FPC, 273 lakes). The transfer functions had a coef…
The environmental history of the oxbow in the Luciąża River valley – Study on the specific microclimate during Allerød and Younger Dryas in central Poland
Environmental changes during Mesolithic-Neolithic transition in Kuyavia Lakeland, Central Poland
The Lateglacial and early Holocene climate variability and vegetation dynamics derived from chironomid and pollen records of Lieporiai palaeolake, North Lithuania
Proxy-based 300-year High Arctic climate warming record from Svalbard
We used fossil Chironomidae assemblages and the transfer function approach to reconstruct summer air temperatures over the past 300 years from a High Arctic lake in Hornsund, Svalbard. Our aims were to compare reconstructed summer temperatures with observed (last 100 years) seasonal temperatures, to determine a potential climate warming break point in the temperature series and to assess the significance and rate of the climate warming trend at t…
Comparison of quantitative Holocene temperature reconstructions using multiple proxies from a northern boreal lake
Four biotic proxies (plant macrofossils, pollen, chironomids and diatoms) are employed to quantitatively reconstruct variations in mean July air temperatures ( T jul ) at Lake Loitsana (northern Finland) during the Holocene. The aim is to evaluate the robustness and biases in these temperature reconstructions and to compare the timing of highest T jul in the individual reconstructions. The reconstructed T jul values are evaluated in relation to l…
A 5500-year oxygen isotope record of high arctic environmental change from southern Spitsbergen
The oxygen isotope composition of chironomid head capsules in a sediment core spanning the past 5500 years from Lake Svartvatnet in southern Spitsbergen was used to reconstruct the oxygen isotope composition of lake water (δ 18 O lw ) and local precipitation. The δ 18 O lw values display shifts from the baseline variability consistent with the timing of recognized historical climatic episodes, such as the Roman Warm Period, the Dark Ages Cold Per…
Meteorological validation of chironomids as a paleotemperature proxy using varved lake sediments
In order to improve the reliability of climate models in their projections for the future, spatially and temporally detailed paleoclimate proxy data are needed. In this study, we examined annually laminated sediments from Lake Nurmijärvi (Finland) for their fossil Chironomidae assemblages over a time period with available meteorological observational data (since 1830s). In doing so, we correlated chironomid-based inferences of summer air temperat…
A 2000-year record of lake ontogeny and climate variability from the north-eastern European Russian Arctic
A lake sediment record from the north-eastern European Russian Arctic was examined using palaeolimnological methods, including subfossil chironomid and diatom analysis. The objective of this study is to disentangle environmental history of the lake and climate variability during the past 2000 years. The sediment profile was divided into two main sections following changes in the lithology, separating the limno-telmatic phase between ~2000 and 120…
New evidence of warm early-Holocene summers in subarctic Finland based on an enhanced regional chironomid-based temperature calibration model
Paleoclimate reconstructions based on biological proxies present methodological challenges, especially during non-analog conditions, such as the early Holocene. Here, two chironomid-based training sets from Finland were amalgamated to create a more accurate transfer function of summer air temperature. The aim was to reconstruct Holocene paleoclimate in northernmost Lapland, in an area that has been either too warm or too cold for reliable reconst…
The relationship between water and air temperature in chironomid-based paleoclimate reconstructions
Fossil remains of larval chironomids are one of the most useful paleolimnological proxies to reconstruct Holocene paleoclimate. We investigate the within-lake distribution of chironomids in relation to water temperature and test the usability of intralake calibration in chironomid-based temperature reconstructions. We compare our findings against the traditional multilake calibration technique in Holocene sediment cores from Finland. The results …
Diatom-inferred total phosphorus from dystrophic Lake Arapisto, Finland, in relation to Holocene paleoclimate
A sediment core from Lake Arapisto, Finland, was examined for fossil diatom assemblages to reconstruct changes in Holocene nutrient availability. Our aim was to investigate the long-term relationship between lake trophic status and climate by comparing the diatom-based phosphorus reconstruction with paleoclimatic proxies. Our results showed that the cold early Holocene was characterized by elevated nutrient conditions concurrent with newly expose…
Sedimentary Cladocera as indicators of past water-level changes in shallow northern lakes
The usability of subfossil Cladocera assemblages in reconstructing long-term changes in lake level was examined by testing the relationship between Cladocera-based planktonic/littoral (P/L) ratio and water-level inference model in a surface-sediment dataset and in a 2000-yr sediment record in Finland. The relationships between measured and inferred water levels and P/L ratios were significant in the dataset, implying that littoral taxa are primar…
Do subfossil Cladocera and chydorid ephippia disentangle Holocene climate trends
We used sedimentary records of Cladocera and chydorid (Chydoridae) ephippia to reconstruct Holocene climate trends from Lake Arapisto in southern Finland. The quantitative temperature record ( T JulyCla ) inferred from subfossil Cladocera was compared with a previously published pollen-based mean annual temperature reconstruction ( T Ann ) from the same lake. Furthermore, proportions of total chydorid ephippia (TCE), indicating proportions of ase…
A 700 year record of temperature and nutrient changes in a small eutrophied lake in southern Finland
This study aimed to distinguish natural and anthropogenic environmental changes, mainly in climate and nutrient conditions, during the past c. 700 years in Lake Hampträsk, southern Finland. We used sedimentary assemblages of aquatic organisms and physical properties of the sediment as proxies for the past environmental conditions. The results of diatom-inferred phosphorus reconstruction indicated that the lake was already meso-eutrophic at c. AD …
