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.

NEW FINDINGS OF RARE MINERALS IN PEGMATITES OF VISHNEVYE MOUNTAINS IN THE SOUTHERN URALS [PDF]

Минералогия, 2019
In addition to previously known 221 minerals, 11 new rare minerals were identified in alkali pegmatites of the Vishnevye Mountains. Yttrialite-(Y)Y2(Si2O7) and huanghoite-(Ce) aCe(CO3 2F were found for the first time in the Urals.

Response of Boreal Winter Atmospheric Blocking to Topographic Forcing Induced by the Tibetan–Iranian Plateau

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract Employing orographic perturbation experiments from a state‐of‐the‐art climate model, this study investigates the topographic forcing associated with the Tibetan–Iranian Plateau (TIP) in modulating Northern Hemisphere boreal winter blocking frequency.

Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1304-1321, July 2026.
Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...

Land Carbon Sink Distribution in Northern Eurasia Is Driven by Climate Change

Global Biogeochemical Cycles, Volume 40, Issue 7, July 2026.
Abstract Boreal forests are a major contributor to the global land carbon sink under rising CO2 concentrations and a changing climate. Carbon sink estimates for Northern Eurasia from forest inventories, flux mapping, and remote sensing have moved toward convergence over the past decade, although substantial differences remain. Several bottom‐up and top‐

Flexible parental care in a songbird correlates with sex‐specific responses to seasonal phenology, mating opportunity and reproductive success

Journal of Animal Ecology, Volume 95, Issue 7, Page 1178-1193, July 2026.
This population‐comparative study reveals that male and female parents respond differently to social and ecological conditions. This sex‐specific responsive strategy is related to the incongruent parental care systems across populations in Chinese penduline tits.
