Modern Pollen and Conifer Stomates from North-central Siberian Lake Sediments: Their Use in Interpreting Late Quaternary Fossil Pollen Assemblages

To determine the modern relationship between pollen and stomate deposition and vegetation, surface sediments from 26 lakes along the Lena River in northeastern Siberia were analyzed for pollen and conifer stomate content. The lakes sampled, crossed a vegetation gradient from tundra, forest-tundra, to closed boreal forest. The pollen spectra of tundra lakes are dominated by Betula and Alnus. Cyperaceae and Poaceae are also abundant. …
