The article presents materials on the ecological and phytocenotic characteristics of Dactylorhiza fuchsii (Druce) Soo in the southern and middle taiga phytocenoses of the Kirov region. In the course of the study, the typical habitats of the species were established. Vegetation analysis carried out using phytoindication scales by D.N. Tsyganov (1983), made it possible to establish fragments of ecological niches in the conditions of the southern and middle taiga. It was found that in the middle taiga phytocenoses, the species is more sensitive to changes in soil factors given by the researcher than in the southern taiga. Analysis of vegetation in terms of hemerobicity indicates the relative resistance of the species to anthropogenic impact.

– The morphological characters variability structure of two closely related species (Orchis punctulata Steven ex Lindl. and O. purpurea Huds.) in forest and steppe communities was studied. In total, six cenopopulations were researched during 2015–2023. An analysis of the variability of 12 morphological characters in 375 generative individuals of O. punctulata and 356 generative individuals of O. purpurea was carried out. We used the following methods: correlated, principal component, linear discriminant. It was found that growing conditions influence the majority (58%) of O. punctulata morphological characters, and do not influence the vast majority (83%) of O. purpurea characters. Ordination by the methods of principal components and discriminant analysis convincingly separates O. punctulata population samples from forest and steppe communities. Population samples of O. purpurea from forest and steppe communities were morphologically homogeneous. The morphological variability specifics of these two closely related species could be explained by different mechanisms of life strategies formation

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
