“…There are meadows on the marine shores and near river mouths. The island flora is similar to the neighboring parts of the continent and there are no signs of endemism [21].…”

“…The peat contains marine diatoms that could have been carried onto land during periods of high storm activity associated with the passage of deep cyclones. The pollen spectra, including those from the surface layer of peat, contain a large amount of pollen from fir, pine, and broad-leaved trees that do not currently grow on the Shantar Islands [21]. Further analysis of these pollen distributions can serve as an indicator of the airflow transport from the continent during the growing season.…”

“…Three altitudinal vegetation belts are well pronounced on Bolshoy Shantar Island [21]. Spruce (Picea ajanensis) and larch forests (Larix cajanderi), as well as mixed stone birch (Betula ermanii)-spruce and spruce-larch forests are widespread up to 300-400 m. Communities with species typical for nemoral forests occur locally and are confined to river valleys.…”

Allochthonous biofossil distribution in the blanket peat bog of Bolshoy Shantar Island was used to analyze atmospheric circulation anomalies in the north-western Okhotsk Sea over the last 12.6 ka. The main aim of this study was to determine periods of intensification of deep cyclones and extreme storms. The composition of bioaerosols is significantly influenced by atmospheric zonal and meridional transport anomalies associated with anomalies of the monsoon system of Northeast Asia, atmospheric fronts and cyclone trajectories. Marine diatoms enter the peatland from the sea during extreme storms and record the passage of sea cyclones in the autumn-winter, whereas the distribution of allochthonous pollen indicates the intensity of continental cyclones. We used Pinus pumila pollen as an indicator of heavy snowfalls and winter cyclone activity. Fifteen phases of extreme storms were identified. Changes in ice coverage also played an important role in bioaerosol emission. During cold periods, emissions of bioaerosols mainly occurred in the open sea, whereas during warm periods, emissions occurred near the coast. The recurrence and intensity of cyclones during the cold seasons depends on displacement of the Siberian High and Aleutian Low. Periods of continental cyclones intensified in spring-summer and coincided with periods of active winter cyclogenesis 2212.

“…However, the islands are unique natural systems. The peculiarity of the terrestrial and aquatic ecosystems of the Shantar Islands lies not in the species richness and the endemism of its representatives, but in the existence of the biota of various origins and ecology, which forms ecosystems of complex composition and structure in the limited islands area [ 5 ].…”

This article presents the findings of the authors’ study of the mire ecosystem vascular plants of the island of Bolshoy Shantar, which is the largest island in the Shantar archipelago. Bolshoy Shantar Island is an insular ecosystem, the study of which can provide insight into the natural “polygons” of evolution at work. The botanical research was conducted through the application of traditional techniques of floristic and geobotanical studies. The material for this article was drawn from 73 floristic and 54 geobotanical descriptions made between 2016–2018 in the north-eastern part of Bolshoy Shantar Island on four mire massifs associated with various hypsometric surfaces. The findings of this study indicate that the flora of vascular plants of the mires of Bolshoy Shantar Island reflect the peculiarities of a regional mire type that formed in the insular conditions of the Pacific. The species richness of the vascular flora of the island’s mire ecosystems is evidenced by a total species count of 158, composed of 109 genera and 48 families, which accounts for more than one quarter (26.3%) of the Shantar archipelago’s flora. Over half of these species (63.7%) form the core of the mire flora.
