Pollen rain composition on Kunashir Island (Kuril Islands)

Year: 2020, Number: 2, Pages: 3-37

Pollen rain composition on central part of the Kunashir Island is analyzed. A comparison between the time of appearance of pollen and spores in the wind flow with the phenological data on the timing of flowering of the main forest-forming species was made. It has been established that pollen rain includes pollen that absent in the surrounding phytocenoses, but which are components of the existing vertical-latitudinal zonality of Kunashir Island and vegetation of adjacent territories. The dependence of the appearance of allochthonous pollen and the weather regime during sampling of pollen rain are shown. It has been established that the flow of pollen from remote areas of the island and adjacent territories due to active wind transfer does not significantly change the composition of the pollen rain. The composition of pollen rain was compared with subfossil pollen spectra.
