2 1 2 3 Pollen grains of Betula exilis, with slightly protruding pores (1) and prominently protruding pores (2); grain sizes and exine thickness vary greatly (3); photos by Larisa Savelieva/Elena Raschke, from: Savelieva et al. (2013)

3 4 5 Pollen grains of Duschekia fruticosa (Alnaster fruticosus, Alnus viridis ssp. fruticosa), with slightly protruding pores and only one, rather incospicuous arcus-like structure between the left and upper-left pores (4), and with prominently protruding pores with two well developed and three incospicuous arcus (5); grain sizes and exine thickness are variable; photos by Larisa Savelieva/Elena Raschke, from: Savelieva et al. (2013)l 6 7 Pollen grains of Ledum palustre (6) and Vaccinium vitis-ideae (7); photos by Larisa Savelieva/Elena Raschke, from: Savelieva et al. (2013)

4 Pollen grains of Larix, pollen from completely developed cones (8, 9, 10) display severe damages including modifications of the pollen grain wall structure; photos by Bastian Niemeyer Pollen grains of Pedicularis lapponica; photos by Larisa Savelieva/Elena Raschke, from: Savelieva et al. (2013) 13 Grain of the pollen type RUBUS CHAMAEMORUS (sensu Beug 2004); from ice-wedge polygon mire Lhc11 near Kytalyk, peat section j20.10, sample at 7 cm depth; stacked photo by Martin Theuerkauf

5 The pollen type RUMEX AQUATICUS T. (sensu Fægri & Iversen 1989), in the Kytalyk area produced by Rumex arcticus; both tricolporate grains (14) and tetracolporate grains occur (15); the pollen grain wall is scabrate (16); from ice-wedge polygon mire Lhc11 near Kytalyk, peat section j20.10, sample at 15 cm depth; stacked photos by Martin Theuerkauf 17 Pollen grain of Valeriana capitata; the echinae are often small and inconspicuous; photo by Larisa Savelieva/Elena Raschke, from: Savelieva et al. (2013)

6 18 Unidentified 3-colpate pollen type with a scabrate wall structure; from ice-wedge polygon mire Lc04 near Chokurdakh, peat section h16; sample at 7 cm depth; stacked photo by Martin Theuerkauf 19 Drawings of four different morphological types of Assulina muscorum tests. Types 1 and 2 have the greatest width in their upper third, and types 3 (asymmetrical) and type 4 (symmetrical) have the greatest width in the centre of the tests; redrawn after Schönborn & Peschke (1990) ASSULINA MUSCORUM TYPE 2 (20) with the largest width in the upper third of the shell, and ASSULINA MUSCORUM TYPE 4 (21) with the largest width in the centre; from ice-wedge polygon mire Lc04 near Chokurdakh, surface sample u23; photos by Martin Theuerkauf

7 22 23 Pollen grains of Saxifraga cernua with a prevailing scabrate pollen wall structure and hardly detectable rugulae/striae; photos by Larisa Savelieva/Elena Raschke, from: Savelieva et al. (2013) Pollen grains of Glyceria declinata with a slightly ovalish shape (24), and with a roundish shape (25); the pollen grains are variable in size; stacked photos by Martin Theuerkauf Beug HJ (2004) Leitfaden der Pollenbestimmung für Mitteleuropa und angrenzende Gebiete.
