Ecological and habitat ranges of orchids in the northernmost regions of their distribution areas: A case study from Ural Mountains, Russia.

The Orchidaceae, which is one of the most interesting families of angiosperms, contains a large number of rare species. Despite their acknowledged importance, little attention has been paid to the study of orchids distributed in northern territories. In this study, we determined the syntaxonomical diversity and ecological parameters of orchid habitats in two of Europe's largest protected areas, the Pechoro-Ilychsky Reserve and the Yugyd Va National Park (northeastern European Russia), and then compared our findings to those in other parts of orchid distribution ranges.

Plant CSR types in the north: comparing the morphological and morpho-physiological approaches.

Unlabelled: Grime's competition-stress-ruderal (CSR) theory is widely used to study plant species' responses to multiple environmental factors. We compared two models to allocate CSR types the global "StrateFy" model (Pierce et al. Funct Ecol, 31:444-457, 2017) and a locally developed morpho-physiological model (Novakovskiy et al.

Changes in mycorrhizal status and type in plant communities along altitudinal and ecological gradients-a case study from the Northern Urals (Russia).

The Ural Mountains (the Urals) are a mountain range on the border between the continents of Europe and Asia. The Urals extend about 2500 km from north to south and run from the coast of the Arctic Ocean to the steppe of northwestern Kazakhstan. In terms of mycorrhizal traits, the vegetation of the Urals has not been studied absolutely compared with the other mountain systems of Europe.
