“…inhabit various ecotopes, including northern taiga regions of the Extreme North, and are considered vulnerable elements of natural ecosystems. Numerous studies, conducted in Komi Republic and bordering territories [1][2][3][4], show that orchids, and genus Dactylorhiza specifically, are sensitive to changes in the environment especially to technogenic factors. This is caused by the peculiarities of their biology and ecology, such as myco-symbiotes, low competitive capacity, high specialism of pollination, and etc.…”

Dactylorhiza maculata (L.) Soó is rare and protected in 25 districts of Russian Federation; it is also included in the IUCN Red List of threatened species. In studied conditions populations of D. maculata are confined to herbaceous and sedge-gramineous marshy meadows of different anthropogenic disturbance. In studied communities the species is characterized by medium quantity and relatively high variability of age groups. Average age spectrum of studied coenopopulations of D. maculata is incomplete double-humped with maximum on immature plants and local peak on generative plants. It was defined that young individuals prevail in ontogenetic spectrum of D. maculata and post-generative fraction is absent. Probably, the peculiarity is one of adaptive mechanisms of the species in conditions of anthropogenic influence and ecological status of typical biotopes in the North-East of Russia. Relatively high values of demographic and morphological parameters are defined for the plants on overgrowing technogenic area with medium disturbance. According to the hemeroby parameter, D. maculata is a species capable of tolerating moderate human impact. The results obtained in studied populations of D. maculata prove favorable conditions for the species in northern taiga ecosystems exposed to moderate or significant recreational stress, as well as sufficient reserves of the species’ stability towards anthropogenic and abiotic factors. Further monitoring of D. maculata is an essential measure necessary for determining ecological-biological peculiarities and range of the species’ tolerance towards different impacts in close-to-critical environmental conditions, which will promote conservation of the populations.

“…Many studies have been carried out concerning the biology of D. fuchsii in anatomy (Aybeke et al 2010;Naczk et al 2010), morphometry and biostatistics (Dufrêne et al 1991;Tyteca and Gathoye 1999;Sumbembayev et al 2021), ontogenesis (Vakhrameeva 2006;Jacquemyn et al 2012), micropropagation (Jakobsone 2008;Jakobsone et al 2010), geographic distribution (Đorđević et al 2014), and genetics (De Hert et al 2012;Box et al 2012;Efimov et al 2016;Wróblewska et al 2019). At the same time, a limited number of population studies of the species were carried out (Bateman and Denholm 1989;Dufrêne et al 1991;Janečková et al 2006;Kirillova and Kirillov 2013;Kotukhov et al 2018;Kosolapova et al 2021;Taraška 2021), especially in the peripheral part of the range. Special studies on the study of populations of D. fuchsii, the ecological characteristics of communities and the floristic composition of these populations in the territory of the Kazakhstan part of the Altai mountainous country have not been previously carried out.…”

Abstract. Sumbembayev AA, Tergenbaeva ZHT, Kudabayeva GM, Tashmetova RS, Genievskaya YA, Szlachetko DL. 2022. Title. Biodiversitas 23: 4385-4399. The article presents the results of studying the current state of populations of a rare species - Dactylorhiza fuchsii in the Kazakhstan Altai. As a result of expeditionary studies, four main regions were identified, which were represented by 12 populations. Floristic plasticity according to the Jaccard coefficient (12-24%) showed a high heterogeneity of the studied populations. The cluster population dendrogram showed a clear dependence of the floristic composition of accompanying species on geographic location in terms of species similarity and difference of communities. External similarity was studied according to 10 morphometric features. The PCA analysis shows that the external structure is influenced by vertical zoning. Pearson's correlation analysis showed a stable direct and inverse dependence of morphometric characteristics on some environmental conditions (0.74-0.95). According to the data ANOVA disperse analysis, among studied environmental factors, soil nutrient richness (N) and humidity (F) had demonstrated the broadest significant effects (P-values from < 2e-16 to 0.001 for N and from 8.02e-09 to 0.02 for F) on plants morphology influencing eight out of ten morphological traits. Distribution regions of D. fuchsii have low vitality, and most populations are characterized as depressed. The results harmoniously complement the fundamental research on the state of D. fuchsii populations throughout the distribution range of the species.
