Terrestrial Plant DNA from Lake Sediments
Predicting and anticipating the effects of current and future climate warming on plant communities requires a comprehensive understanding of past ecosystem dynamics. In this context, Palaeoecological studies using sedimentary ancient DNA (sedDNA) offer unique advantages over conventional pollen and...

Predicting and anticipating the effects of current and future climate warming on plant communities requires a comprehensive understanding of past ecosystem dynamics. In this context, Palaeoecological studies using sedimentary ancient DNA (sedDNA) offer unique advantages over conventional pollen and macrofossil methods due to higher taxonomic resolution and better detection of insect pollinated taxa than pollen, and higher detectability than macrofossil. Like macrofossils, sedDNA is mainly deposited within the catchment and thus provide a more geographically constrained catchment area than pollen. To ensure accurate reconstructions, it is vital to comprehend DNA preservation and degradation processes in sediments. Molecular ecology techniques like metabarcoding, shotgun sequencing, and capture probe methods have revolutionized the detection of floral diversity through sedDNA analysis.
