Chromitite deposits of Ufaley ultramafic massif (South Urals)
Georesursy, 2022 Data on the morphology, composition, textural and structural features of chromite deposits of the Ufaley ultramafic massif are presented. The mineralogical and compositional features of the host ultramafic rocks allow us to interpret them as depleted restite from partial melting of mantle peridotites.

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

El Niño Events Enhance Melting of Sea Ice in the West of Greenland
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Using reanalysis data sets and numerical simulations, this study investigates the linkage between El Niño events and spring Arctic sea ice melt rate (AMR) in the west of Greenland. The results indicate that the accelerated spring AMR often corresponds to the previous winter's El Niño–like sea surface temperature anomalies.
