Highlights:
-
The first integrated analysis of DNA, pollen and macrofossils from permafrost faeces.
-
Successful amplification of up to 28,6 kyr old DNA using long, plant-specific nrITS.
-
High taxonomic resolutions allow detailed insights in extinct megafaunal habitat.
-
Macrofossils and DNA show diverse woolly mammoth diet and use of ‘mammoth steppe'.
