Assessing the extent to which changes in lacustrine biodiversity are affected by anthropogenic or climatic forces requires extensive palaeolimnological data. We used high-throughput sequencing to generate time-series data encompassing over 2200 years of microbial eukaryotes (protists and Fungi) diversity changes from the sedimentary DNA record of two lakes(More)
For several decades, global change has resulted in an increase in runoff in the Sahelian belt, provoking major changes in the quality and quantity of sediments transported by drainage networks. One of the astonishing consequences is the establishment of numerous permanent lakes. The origins of particulate organic matter (OM) preserved within lacustrine(More)
We aim at understanding the influence of climate change on the functioning of two freshwater lakes in South Greenland by combining limnological and paleolimnological methods. The results offer a means of testing the potential use of subfossil chironomid for paleoclimate reconstruction. First, the current ecological status of Lake Igaliku and Lake 95 has(More)
