CC-BY 114 WORKSHOP REPORT the projected climatic changes and increasing anthropogenic pressure by the end of this century are generating global concerns about the potential impacts on environment and society. Most environments are currently shaped by the interactions between the changing climate and human disturbances, therefore understanding environmental dynamics cannot be achieved without considering both climatic and anthropogenic drivers (Dearing et al. 2015). An increasing number and diversity of paleoclimatic studies spanning the Holocene have indicated that climate underwent complex developments that rarely followed larger spatial scale patterns (e.g. Wenniger et al. 2009). However, at continental levels the cohesion of climatic shifts was documented to increase, as more and more archives, unevenly distributed across Europe, contributed to the state of knowledge.

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”/”jezero”/”jezioro” and “bolătău”/”blato”/ ”błoto”) are largely regarded as archaic forms, particularly “bolătău”/ ”blato”/”błoto” throughout the study area. However, toponyms based on both words are still in use in a large number of derivative variants (especially in the Slavic-speaking countries), which attest their age and relevance in the toponymical practice, albeit to a different extent and with national and regional variations in terms of occurrence. The study also indicates that, whereas the research topic requires further exploration in the shape of a quantitative approach investigation, given the complexity of toponymical studies within such an extensive area, it can be inferred that currently the vast majority of toponyms based on the two terms do not refer to water bodies, but have been transferred to other elements of the landscap

a b s t r a c tFinely laminated sediment records have been studied from a small landslide-dammed lake (Bol at au) located in Bukovina, Romania. An age-depth model for the Bol at au sediment record was established based on 8 AMS radiocarbon dates from terrestrial macrofossils and the double peaks of the 137 Cs flux (i.e. mid-1960s: global fallout maximum; 1986: Chernobyl accident). The onset of the lacustrine sedimentation is estimated to~5e6.5 ka while the landslide event can be constrained by~6.8e7 ka as an inferior age estimate. The laminated structure is interpreted as organic and clastic type varvite at the lower and upper part of the core, respectively. Major fluctuations found in the coarsely sampled (5 cm) stable carbon isotope data showed remarkable correspondence with nearby palynological records and a lacustrine d 13 C record. It suggests that the sediment record preserves environmental signals with a broader regional relevance. The established timescale provides the necessary chronological basis of the records from Lake Bol at au for further analysis.
