LifeMet: Report on the 2024–2025 meteorite recovery expedition in Dronning Maud Land, Antarctica for the study of microbe–meteorite interactions

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 8, Page 1847-1860, August 2026.
Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.

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

open access: yesJournal 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.

External water exchange of reservoirs of South Ural

open access: yesIOP Conference Series: Earth and Environmental Science, 2019
Abstract Reservoirs are building worldwide for the rational usage of water resources. Engineers create reservoirs for redistribution of runoff both in seasonal and multi-annual regime. The duration of stay of river water in slow water exchange condition is one of the major factors which influences the transformation of the river water ...

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

open access: yesPLANTS, 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

open access: yesGlobal 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‐

Late Campanian (74–71 Ma) Arabia–Eastern Anatolia Collision and Its Geodynamic Implications

open access: yesTectonics, Volume 45, Issue 7, July 2026.
Abstract The East Anatolian Plateau is a major collisional feature within the Tethyan realm formed as a late‐stage result of the collision between East Anatolia and the Arabian Platform. The timing of this collision is highly debated, with estimates from the Late Cretaceous to the Miocene.

Biodiversity of Terrestrial Cyanobacteria of the South Ural Region

open access: yesCryptogamie, Algologie, 2018
South Ural is a territory with a unique geographical position and heterogeneous natural conditions. Unexplored biodiversity of the terrestrial cyanobacteria of this territory is very high. We undertook a floristic study covering all botanical-geographical zones of the Bashkiria and Bredinskiy district of the Chelyabinsk region.

Geochemical features of groundwater in the South Urals

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2016
This paper gives an analysis and generalization of the data on groundwater chemical and gas composition, located deep in the largest tectonic structures of the Urals. The distribution of groundwaters by the degree of mineralization and composition is subjected to the normal vertical hydrogeochemical zonation.
