Intralake data set of fossil midge assemblages from Lake Pieni-Kauro (FIN)

Midge (Insecta: Diptera: Nematocera) assemblages were examined in surface sediment samples from Lake Pieni-Kauro and the Saavanjoki River, eastern Finland, using their sedimentary remains. The aim was first to identify the forcing factors behind midge distribution within an aquatic ecosystem and second to develop new midge-based calibration models for the reconstruction of past environmental conditions, with a special focus on paleohydrology. The third objective was to apply the models to a midge stratigraphy. The effect of sampling-point selection in paleolimnological studies and its possible influence on chironomid-inferred temperature reconstructions was also assessed.
