Vegetation patterns, recent pollen deposition and distribution of non‐pollen palynomorphs in a polygon mire near Chokurdakh (NE Yakutia, NE Siberia)
Fine‐scaled distribution patterns of vegetation and palynomorphs in a polygon mire in NE Siberia were studied in 31 × 31 plots of 1 m 2 (vegetation) and along a transect at intervals of 1 m (palynomorphs). Pollen and non‐pollen‐palynomorph contents clearly reflect differences between polygon ridges...
