Сommunities of xerotheme shrubs of South Urals

Vegetation of Russia
Communities of shrubs such as Prunus fruticosa, Spiraea crenata, S. hypericifolia, Caragana frutex (Lavrenko, 2000) are widespread in the Eurasian steppe region. Currently, science has a special interest in the study of shrub communities and some species of shrubs due to their expansion into grass ecosystems.

Reidite Formation From Zircon Subjected to 20, 40, and 60 GPa Shock Experiments

Journal of Raman Spectroscopy, Volume 57, Issue 8, Page 1392-1406, August 2026.
Structure disordering as a result of shock pressure: In zircon shocked from 20 to 60 GPa, the shock‐induced structural disorder increases with increasing shock pressure (gray area). Shock disorder of zircon is an integral part of its transformation to reidite: Reidite occurs after amorphous material.

Resident and Migratory Falcons' Breeding Phenology and Productivity Respond Differently to Weather and Climate Change Across the Arctic

Global Change Biology, Volume 32, Issue 8, August 2026.
Climate change is altering breeding phenology and productivity of peregrine falcons and gyrfalcons across the circumpolar Arctic. Long‐term monitoring shows that responses vary among study areas and Arctic regions, with some populations advancing hatch dates while others show weaker or contrasting trends, highlighting spatially variable effects of ...

GENETIC DIVERSITY OF SIBERIAN STONE PINE UNDER INTRODUCTION IN THE SOUTH URALS AND BASHKIR CIS-URALS

Сибирский лесной журнал, 2016
Allozyme polymorphism of Siberian stone pine Pinus sibirica Du Tour has been studied in 14 artificial stands in the South Urals and Bashkir Cis-Urals on the base of 7 gene-enzyme system analysis. The following values of genetic diversity are determined: mean number of alleles per locus (A) constitutes 1.69±0.08; portion of polymorphic loci (P95) – 50.0
