Palaeocladocerans as indicators of environmental, cultural and archaeological developments in Eifel maar lakes region (West Germany) during the Lateglacial and Holocene periods

摘要: The use of subfossil cladocerans is rare for understanding environmental, cultural and archaeological developments lakes in Europe. In 2007, we collected a 12-m long sediment core from Lake Schalkenmehrener Maar (SMM), Germany the analyses cladocerans. Dating was based on tephrochronology, radiocarbon pollen stratigraphy. Pollen-based chronostratigraphy indicated decline species richness abundance chydorids during Lateglacial (ca.14500 cal yr bp) with dominant cold preferring taxa Acroperus harpae Baird Alona affinis Leydig. During early Bolling, increased commensurate growth birch (Betula L.) pine (Pinus trees. Except spike Bosmina coregoni Younger Dryas, cladoceran assemblages remained stable Bolling to mid-Atlantic period. Neolithic (ca. 4300 bc), B. sharply reciprocal decrease Daphnia.
