Main climate parameters of the winter season and features of the biological spectrum of vascular plant flora in the Tom River basin.

Pair correlation coefficients have been calculated using the biological spectrum of vascular plants of the Tom River basin, as well as the data on monthly average air temperature during the winter season, snow-cover thickness, and snow-water equivalent. It is determined that the impact of air temperature on different life forms on the plains and in the mountains varies and is displaced in time. The features of the biological spectrum of the flora are largely determined by hydrothermal conditions during the winter. [ABSTRACT FROM AUTHOR]
