Late Glacial development of lakes and wetland vegetation in a dune area in Central Poland

This study investigated the history of the development of six, paleo-lakes, which are at present filled with sediments, in a dune area in Central Poland, based on multiproxy paleoecological analyses and accelerator mass spectrometry radiocarbon dating. The aims of the paleoecological studies were: i...

The results of the paleobotanical analysis suggested that the reservoirs were shallow, oligo-mesotrophic, inhabited by pioneer calcicole vascular plant species such as: Chara sp., Hippuris vulgaris , Potamogeton natans , Potamogeton fresii , Potamogeton alpinus and Potamogeton filiformis , and mosses such as: Pseudocalliergon trifarium , Calliergon sp. and Calliergonella cordifolium . The area next to the reservoirs was covered with sparse pine forests combined with birch, which is typical of the Late Glacial period. The open areas were dominated by psammophilic and steppe vegetation, including Poaceae, Artemisia and Hippophae rhamnoides . Geochemical analysis revealed that Ca 2+ and Fe 3+ were in high concentrations, which could have influenced the presence of taxa preferring soil with high Ca 2+ content. The accumulation of calcium in sediments confirms that the reservoirs were fed by groundwater originating from the progressive degradation of permafrost associated with thermal changes.
