The lake is very sensitive to both climate changes and human impacts. Surroundings have been inhabited since the Stone Age; however, heavy human impact can be recognized during the past 6000 years. In this study, we established three different stages for and reconstructed water level changes of Lake Balaton by geochemical data, subfossil Cladocera and diatom remains in the sediments of the Zalavári Pond, a part of the Kis-Balaton wetland. In 9900–8600 cal. year BP, climate was dry, water level was low, and there was a wetland in this area. Although organic matter content was low in the sediment, the ratio of Fe/Mn was high. Between 5600 and 5000 cal. year BP, water level increased, Fe/Mn ratio shows that oxygen conditions of sediments was improved in agreement with the relatively low number of diatom remains and dense chydorid remains. About 5000 cal. year BP, water level of Lake Balaton decreased as indicated by high organic content with low carbonate and high Fe/Mn ratio in the sediments (oxygen depletion). At the bottom of this section, high Fe and S concentrations showed accumulation of pyrite (FeS2) that is common in wetlands with very low redox potential. Low abundance of Cladocera remains together with rich and diverse diatom flora confirm the low water level hypothesis. Our data support that the water level of Lake Balaton was higher between 8600 and 5000 cal. year BP than it is at present.}, year = {2010}, eissn = {1573-5117}, pages = {225-244}, orcid-numbers = {Korponai, János/0000-0003-0211-192X; Papp, István/0000-0002-0006-9919} } @article{MTMT:1477813, title = {Will dry events occur more often in Hungary in the future?}, url = {https://m2.mtmt.hu/api/publication/1477813}, author = {Gálos, Borbála and Lorenz, Ph and Jacob, D}, doi = {10.1088/1748-9326/2/3/034006}, journal-iso = {ENVIRON RES LETT}, journal = {ENVIRONMENTAL RESEARCH LETTERS}, volume = {2}, unique-id = {1477813}, year = {2007}, eissn = {1748-9326} } @article{MTMT:1102195, title = {Changes in the mosaic-like water surfaces of the Lake Velence as reflected by reed periphyton studies}, url = {https://m2.mtmt.hu/api/publication/1102195}, author = {Ács, Éva and Buczkó, Krisztina and Lakatos, Gyula}, journal-iso = {STUD BOT HUNG}, journal = {STUDIA BOTANICA HUNGARICA}, volume = {25}, unique-id = {1102195}, issn = {0301-7001}, year = {1994}, pages = {5-19}, orcid-numbers = {Ács, Éva/0000-0003-1774-157X} }
