Subfossil Coleoptera from Eifel maar sediments as indicators of the environmental evolution in Central Europe over the last 60,000 years
A reconstruction of landscape and paleotemperatures is presented from a composite drill core from the Eifel maar lakes of Auel and Holzmaar, Germany. The compositecore is 112 m long and covers the last 60,000 years (Marine Isotope Stages MIS 3, 2, and 1) based on the new ELSA-20 stratigraphy. Findin...

A reconstruction of landscape and paleotemperatures is presented from a composite drill core from the Eifel maar lakes of Auel and Holzmaar, Germany. The compositecore is 112 m long and covers the last 60,000 years (Marine Isotope Stages MIS 3, 2, and 1) based on the new ELSA-20 stratigraphy. Findings are based on an analysis of arthropod remains, with moisture-dependent, riparian or (semi)aquatic Staphylinidae representing the majority of beetle sclerites in the assemblages, especially during cold intervals. Assemblages change corresponding to climate and vegetation, with a greater variety of taxa during the woodland phases (60,000–44,000 yr b2k, i.e. years before 2,000 CE) versus cold adapted taxa during late MIS 3 and early MIS 2 (28,500–23,500 yr b2k).
