Spatial and temporal structure of the Acer negundo L. cenopopulation in the forest parks of Yekaterinburg

Abstract

The article is devoted to the study of the spatio-temporal structure of Acer negundo L. in the forest parks of Yekaterinburg on the basis of population and organism indicators. Eight fragments of ash-leaved maple cenopopulations in the Uktussky and Southwestern forest parks were examined. For the first time, a quantitative characteristic of the manifestation of organismal indicators in each ontogenetic state of maple was obtained. A feature of the spatial structure of the habitats of Acer negundo is its active introduction into cenoses in the forest parks of Ekaterinburg. An identical expansion of the species in the studied forest parks was established, however, there are also distinctive features of its habitat. In the course of the analysis of variance, the dependence of the dimensional parameters of the maple crown on changes in two factors (forest park, ontogenetic state) and their interaction was shown. The ability of the species to successfully adapt in fragmented and urbanized areas affected by recreational impacts and other forms of pollution and survive in a wide range of environmental conditions has been established. © Published under licence by IOP Publishing Ltd
