title: Spatial structure of Colchicum s. l. (Colchicaceae, Liliopsida) populations in European Russia
abstract: Analysis of the spatial structure of 43 populations of five species of geophytic ephemeroids of European Russia, Colchicum s. l, was carried out in 2021–2024. The distribution patterns of individuals, displayed by the Ripley function L(r)–r, were implemented in the spatstat package for the R programming language. Within the range of the genus, the occurrence frequency of populations with a random distribution type increased from north to south. In C. laetum and C. bulbocodium subsp. versicolor,
