^b Two samples combined (i.e. sediment interval 1.5 cm instead of 0.5 cm).

Figure 1. Pollen percentage diagram from Lake Öagöl. Black graphs show percentages and grey graphs show exaggeration (× 10). Constrained cluster analysis (CONISS) in Tilia (v.2.0.41) was used to identify local pollen assemblage zones (LPAZs). The pollen sum includes all terrestrial pollen taxa.
