Acting as sensitive and accurate barometers, lake and peat sediment records enable us to acquire an increasingly broader perspective on the mechanisms behind climatic and environmental changes. Over the past two decades, the rising number and amount of data yielded by palaeolimnological studies for the Central–Eastern Europe, in general, and Romani...
Fallout isotope ((210)Pbex,(137)Cs and (241)Am) based dating has been carried out on the near-surface sediment core collected from Lake Bolătău-Feredeu (Bukovina, Romania). The motivation was to improve the chronology of this recent section in connection with significant fluctuations observed in sediment accumulation rates, particle size distributi...
Lake Bolătău-Feredeu is a small (surface: 0.3 ha; catchment area: 31 ha) landslide-dammed lake in Bukovina (Eastern Carpathians, Romania). Elemental concentration, stable isotope composition of carbon and nitrogen, and n-alkane composition of the saturated hydrocarbon fraction of the organic material were analyzed along the sediment profile from La...
Heavy metal pollution in the Danube Delta (in sediments, water and living organisms) has recently received increasing attention due to its impact on ecosystems health and water quality. However, long term records of heavy metal contamination are not available to date. In this study radiometric dating and geochemical analyses for major elements (Al,...
Fires influence basic ecosystem processes, including the distribution, the structure and the composition of vegetation, as well as the carbon cycle and climate at the global scale. Long-term knowledge (i.e., centuries or millennia) of fire regime history and forest fire ecology and dynamic in local environments is necessary for sustainable ecosyste...
The research area is located in the Eastern Carpathians, Romania. This region is rich in various formations and indicates significant potential for paleo-environmental reconstruction. The present research was carried out on sediment cores collected at lake Bolătău-Feredeu, Feredeului Mountains (Eastern Carpathians, Romania). Preliminary examination...
The catchment (bedrock and soil) and sediments of lake Bolătău, Romania were studied by high resolution multi-methodological investigations to characterize paleoenvironmental and formation conditions. Particle size analyses, optical and cathodoluminescence microscopy, FTIR-ATR and Raman spectroscopy, X-ray powder diffraction, and XRF were applied f...
In the present paper we introduce lake Bolatau, located in Obcina Feredeului, Eastern Carpathians (Romania), with seasonally controlled sedimentation and significant potential for generating precipitation sensitive proxy record. Two sediment cores were compared against each other in order to achieve a better understanding of the lateral discontinui...

The paper aims to investigate the distribution and evolution of toponyms derivative of the words „iezer” and “bolătău” (Romanian) and their counterparts in the neighboring countries, where such homologous words/toponyms exist, i.e. Poland, the Czech Republic and Slovenia. We documented that at present the terms where the toponyms originated (“iezer...
Landscape change affects natural ecosystems and poses major challenges to natural resource managers and planners. Studies have shown that streams and rivers are often the ecosystems most affected by stressors associated with urbanization, and composition within a watershed has been found to account for much of the variability in aquatic ecological...
The dynamic of urban landscapes, in terms of land use/land cover change, is strongly influenced by the underlying changes in economical processes and political factors. Consequently, in a territory undergoing transition from state ownership and management of all resources to free market based on individual property, such as the city of Fălticeni po...
