“…In relation to the conservation issue of R. rosea, it is necessary to study the state of the species' coenopopulations within its natural range. Assessment of the biological features, ontogenetic, ecological, and phytocenotic structure of R. rosea populations has previously been conducted in the southern Urals and in the highlands of eastern Kazakhstan (EK) [10,11]. However, we are presenting the first study of the variability of the morphostructure traits of the aboveground part of the mature plants of this species in natural cenopopulations (CP) in the Altai Republic.…”

Rhodiola rosea L. is a vulnerable species in the Altai Republic (AR) and Russia in general. For the first time on the territory of AR, studies of the adaptive capabilities of the species and genetic differentiation using ISSR markers were carried out in seven cenopopulations (CP) of R. rosea in 2018 and 2020. The research was founded on the notion of conducting a comparative analysis of the morphogenetic structure of Rhodiola rosea populations in various ecological and geographical conditions of AR. The aim of this work is to evaluate the variability of morphometric traits of sexually mature living female R. rosea plants and to conduct a comparative analysis of genetic variability in cenopopulations (CP) both under undisturbed conditions and under stressful conditions of anthropogenic impact (grazing). Of the 8 primers used, HB12 turned out to be the most informative. The percentage of polymorphic loci in the populations between 0 and 88%. Two populations, located in favorable conditions at relatively low absolute altitudes (2000 m above sea level) (masl) in the undisturbed habitats of the Katun and Altai reserves of AR, were characterized by higher polymorphism. The share of polymorphic loci reached 80%. According to the analysis of statistical data, the highest values of morphometric parameters of the aerial parts of R. rosea plants and the highest potential seed productivity were also recorded in these habitats. Representatives of two high-mountain CPs (2400–2500 masl) in the Sailyugemsky National Park (SNP) were characterized by the lowest genetic polymorphism. Their genetic structure is the most homogeneous, since we have not found polymorphic loci. Due to spatial isolation, these individuals are reliably genetically differentiated. In addition, individuals of one type were subjected to stressful anthropogenic impact (grazing). Therefore, the smallest sizes and lowest potential seed productivity were recorded. Our research shows that alpine populations of R. rosea in AR, under conditions of anthropogenic stress, need protection for their gene pool.

“…The stages of morphogenesis of the species and the maximum age of wild populations of R. rosea are also poorly studied (Brinckmann et al 2021 ). The studies of many Russian scientists are devoted to the study of ecological and botanical proper-ties, distribution, ontogeny of populations (Sofronov et al 2016 ; Valuiskih et al 2017 ; Panossian et al 2010 ; Yakubov et al 2019 ; Shadrin et al 2020 ). A relatively fewer population ecological studies of R. rosea were performed in Europe and North America (Olfelt et al 2014; Aiello et al 2013 ), however, the research on genetic diversity and phylogeography of populations are well represented (György et al 2012 ; György et al 2013 ; György et al 2014 ; Soni et al 2010 ; Kozyrenko et al 2018 ).…”

Background Based on world experience, first, a modern assessment of the flora is needed to develop strategies for the conservation of ecosystems of rare and endangered plant species. A regional and global biodiversity strategy should focus on assessing the current state of bioresources. To preserve the biodiversity of the species and its habitat, we evaluated botanical features, ontogenetic phases, the ecological and phytocenotic structure of the rare and endangered of Rhodiola rosea L. (golden rose root) populations from the highlands of Eastern Kazakhstan. Results R. rosea in the study region lives on damp mossy rocks, rocky slopes, overgrown moraines and along the banks of mountain rivers in the upper limit of cedar-larch forests, subalpine and alpine belts, in the altitude limit of 1700–2400 m. In the studied region, R. rosea begins to vegetate in May–June, blooms in June–July, the fruits ripen in August. The species is encountered in the high mountain ranges of the Kazakh Altai and Saur-Tarabagatai. Unfavorable habitat conditions for the species are overgrown by sedge-grass and birch-moss communities. The most common species at sites with R. rosea are: Schulzia crinita, Achillea ledebourii, Doronicum altaicum, Macropodium nivale, Hylotelephium telephium, Rhodiola algida, Carex capillaris, C. aterrima. Ontogenetic study revealed that all age-related phases were present, with the exception of the senile states. Individual life expectancy shown to be 50–55 years. The analysis of the species composition in the communities with R. rosea showed that the leading families in terms of the number of accompanying species are Poaceae, Ranunculaceae, Asteraceae, Rosaceae and Caryophyllaceae, Apiaceae, Fabaceae; while the most dominant genera are: Carex, Aconitum, Dracocephalum, Festuca, Pedicularis, Poa, Salix; the ecological groups are dominated by psychrophytes, mesophytes mesopsychrophytes; the Asian, Eurasian, and Holarctic groups are the most represented groups. Dominant life forms according to Serebyakov were rod-rooted, brush-rooted, short-rooted and long-rooted grasses, while based on Raunkiaer’s groups the overwhelming majority consisted of Hemincryptophytes (74%). Conclusions The R. rosea populations of Kazakhstan represent an important gene stock of the species. Our study provides new insights into the species’ biology thus contributes to the conservation of biodiversity on a wide spatial scale.

Background: Based on world experience, first, a modern assessment of the flora is needed to develop strategies and tactics for the conservation of ecosystems of rare and endangered plant species. A regional and global biodiversity strategy should focus on assessing the current state of bioresources. In this regard, to preserve the biodiversity, the botanical features, the ontogenetic state, the ecological and phytocenotic structure of the rare endangered species Rh. rosea in the highlands of Eastern Kazakhstan were studied.Results: Ten populations of Rh. rosea were identified under various ecological and geomorphological conditions with a detailed description of the structure of the plant community. Systematic analysis of the plant community with Rh. rosea shows that the families Poaceae Barnhart, Ranunculaceae Juss., Asteraceae Bercht, J. Presl, Rosaceae Juss. and the leaders in the number of species are Caryophyllaceae Juss., Apiaceae Lindl., Fabaceae Lindl., Polygonaceae Juss. They make up 97 (69%) of the species in the plant community. Ecological analysis data show that the plant community is dominated by psychrophytes (32%), mesophytes (28%), mesopsychrophytes (11%) and mesoxerophytes (7%). Chorological analysis of plant populations with rh factor. rosea indicates that the Asian group (39%), the Eurasian group (30%), and the Holarctic group (20%) are the most widely represented. In Rh. rosea populations, it is most often found with Schulzia crinita, Achillea ledebourii, Doronicum altaicum, Macropodium nivale, Hylotelephium telephium, Rhodiola algida, Carex capillaris, C. aterrima, C. stenocarpa, Euphorbia pilosa, Trifolium lupinast. In the ontogenesis of Rh. rosea, all age-related conditions were identified, with the exception of the prussic condition, and the life expectancy is 50-55 years.Conclusions: The state of Rh. rosea populations is assessed as satisfactory, capable of self-sufficiency mainly due to vegetative reproduction. Seed renewal is low as a result of seedling death in the early stages of development due to extreme habitat conditions. In communities with Rh. rosea, one - and two-species families predominate, which indicates the complexity of the process of florogenesis in extreme conditions of existence. In general, the distribution of life forms, ecological groups, and species composition of communities with Rh. the participation of the rose is natural for extreme conditions of existence.
