“…In such ecosystems, R. glacialis grows on coarse grained debris on steep slopes, in places of late snowmelt. Earlier study of Koroleva and Kopeina (2020) ascribed the community type not to snow bed vegetation but to Racomitrium spp. -Ranunculus glacialis of order Androsacetalia alpinae and class Thlaspietearotundifolii.…”

Ranunculus glacialis (L.) A. Löve & D. Löve is a rare species that is included in the Red Data Book of the Murmansk region. It belongs to a group of northern species that, under climate change conditions, will be exposed to a reduction of range and loss of genetic diversity. The objective of this study was to estimate the adaptive potential of this species in the Khibiny Mountains, which is the edge of the eastern limit of its range. Plants growing in natural conditions of the Khibiny Mountains and in the nurseries of the Polar-Alpine Botanical Garden-Institute (PABGI) were compared in terms of leaf mesostructure and pigment content. Under nursery conditions, at higher temperature than in the field, R. glacialis plants showed quantitative rearrangement of leaf mesostructure. Changes associated with increases in internal leaf volume and disturbance of ontogeny, changes in morphometric indicators of assimilating organs (mass and leaf area), reduced productivity and, consequently, reduced resistance to growing conditions were also found in the PABGI-cultivated plants. In this study, we show that this species has a low level of genetic diversity and a limited adaptive potential in the extreme eastern edge of its range in Russia (Kola Peninsula), as evidenced by numerous experiments on acclimatization of R. glacialis under nursery conditions in the Khibiny Mountains.

The Khibiny Mountains are a territory with a high botanic diversity and include value habitat types. We analyzed the representativeness of the herbaria of the Polar-Alpine Botanical Garden-Institute (KPABG) and the Institute of Industrial ecology Problems of the North (INEP) in relation to protected species of vascular plants in the Khibiny. The collections include 34 of 49 protected species recorded in literature. In the course of the analysis, the complete information from the herbarium labels was converted into electronic format and prepared to include into the database of the “Flora of Russian Lapland”. In the absence of precise geographic coordinates on the labels, geo-referencing was performed according to a standardized protocol using topographic maps of the Khibiny Mts at a scale of 1:100,000, archival materials (field diaries and reports) and high-resolution satellite images of the earth’s surface. Most of the regionally protected species in herbaria were collected in the most accessible southern part of the Khibiny, near by the human transformed territories and along a dirt road through the mountain pass. regional botanical Natural Monuments and federal Protected Area Polar-Alpine Botanical Garden-Institute are among the best studied. The herbaria include specimens collected over almost hundred-of-years periods and almost no specimens of protected species from the “Khibiny” National Park.
