The emergence of molecular analyses based on the sequencing sedimentary DNA has opened up many new areas inquiry in paleolimnology. preserved sediments (SedDNA) offers possibility to consider taxa that were traditionally not accessible because they do leave distinct morphological fossils. Recent applications considered a diversity biological groups (including bacteria, protists, zooplankton, fi...
Zooplankton of the family Bosminidae have a unique paleolimnological record in many Holarctic lakes that provides a near continuous record of morphological change for thousands of years. If this morphological change could be interpreted reliably, then a rarely achieved direct observation of macroevolution would be feasible. We tested paleolimnological predictions derived from morphological vari...
