A Comparative Pattern for Populus spp. and Betula spp. Stand Biomass in Eurasian Climate Gradients

Abstract

Based on the generated database of 413 and 490 plots of biomass of Populus spp. and Betula spp. in Eurasia, statistically significant changes in the structure of forest stand biomass were found with shifts in January temperatures and average annual precipitation. When analyzing harvest data, the propeller-shaped biomass patterns in the gradients of average annual precipitation and average January temperatures are obtained, which are common for both deciduous species. Correspondingly, Populus and Betula forests show a regularity common to the biomass components: in the cold zones the precipitation increase leads to the increase of biomass, and in the warm ones to their decrease. In wet areas, the increase of temperature causes the decrease of biomass, and in dry areas, it causes their increase. In accordance with the law of the limiting factor by Liebig-Shelford, it is shown that both an decrease in temperature in dry conditions and a increase in precipitation in a warm climate lead to a decrease in the biomass of trees.

Vegetation–edaphic correlation and importance value index in himalayan ‘ecotone’ temperate conifer forest using the multivariate technique

“…Variations in vegetation are largely influenced by climate factors like temperature, precipitation, and human interference ( Anees et al, 2022a , Ali et al, 2017 ). Climate change is causing vegetation to respond in a response that is extremely important to emphasize ( Usoltsev et al, 2020 , Andreevich et al, 2020 , Shobairi et al, 2022 , Usoltsev et al, 2022 ). Among the most important environmental factors affecting vegetation are temperature and precipitation ( Ali et al, 2023a , Anees et al, 2022b ).…”
