The Patterns of the Distribution of Allergenic Plants in the Plains Biomes of Russia

This article analyzes a set of species of allergenic plants in the lowland biomes of Russia. Their species diversity was revealed, a statistical analysis of the relationships between the number of allergenic plant species in regional biomes and climatic indicators was carried out, and the corresponding maps were built and their analysis was given. It is shown that the distribution of the number of allergenic plant species in the spring reflects their clear predominance in broad-leaved forest and forest-steppe biomes, while in the summer allergenic plants predominate in forest-steppe and steppe biomes. The closest positive relationship has been established between the number of allergenic plant species that bloom in the summer and the average annual air temperature, as well as between all allergenic plant species and the average annual air temperature. However, the relationship between the number of allergenic plant species in the biome and the aridity index turned out to be low.
