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.

[A kinetic lattice model of the chain-melting phase transition in lipid membrane: its experimental calibration and physiological implications].

A kinetic lattice model of chain-melting phase transition has been developed. Its time scale has been calibrated with the acoustic relaxation spectroscopic data. The model presents a tool for the analysis and predictions of kinetic features of those physiological processes in biological membranes whose mechanism is based on the phase transition in the lipid component.
