External water exchange of reservoirs of South Ural
IOP 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 ...

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.

ABOUT THE COMPOSITION OF CASSITERITE AND WOLFRAMITE IN ORES FROM THE FAR EAST DEPOSITS [PDF]
МинералогияThe paper presents formulas, which reflect the variations in the composition of cassiterite, wolframite (ferberite and hübnerite) and associated minerals (silicates, phosphates, tantaloniobates, sulfides, etc.) from the Maly Khingan tin deposits (Khingan

A first assessment of genetic variability in the longhorn beetle Rosalia alpina (Coleoptera: Cerambycidae) from the Italian Apennines [PDF]
, 2018 The Rosalia longicorn (Rosalia alpina) is a strictly protected saproxylic beetle, widely distributed in Central and Southern Europe and mainly associated with ancient beech forests. To improve knowledge about the conservation status of R. alpina in Italy,

Geochemical features of groundwater in the South Urals
Известия 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.

Ecography, Volume 2025, Issue 10, October 2025.Pelagic‐feeding seabirds deliver nutrient subsidies that enhance the productivity, biodiversity, and resilience of terrestrial and marine ecosystems, particularly in nutrient‐poor tropical environments. However, the biogeophysical variables governing the fluxes of these nutrients within and among interconnected ecosystems remain poorly understood.

Limnology and Oceanography, Volume 70, Issue 10, Page 2982-2997, October 2025.Abstract Freshwater bivalves are globally distributed, diverse, and common in benthic communities. Many taxa, particularly in the most species‐rich order, Unionida, are declining due to anthropogenic stressors, while a small number of non‐native species have become increasingly abundant and widespread, commonly replacing native bivalve assemblages.

Landscape patterns of shrubification in the Siberian Low Arctic: A machine learning perspective
Journal of Ecology, Volume 113, Issue 10, Page 2813-2831, October 2025.We quantified landscape patterns of Arctic shrub distribution and change in Siberian tundra by applying machine learning to paired satellite images acquired 10–15 years apart. This pipeline quantified shrub occurrence along landscape‐scale gradients in microclimate, soil moisture, and proximity to existing shrubs, revealing landscape settings that ...

Molecular Ecology Resources, Volume 25, Issue 7, October 2025.ABSTRACT In the last three decades, DNA sequencing of ancient animal osteological assemblages has become an important tool complementing standard archaeozoological approaches to reconstruct the history of animal domestication. However, osteological assemblages of key archaeological contexts are not always available or do not necessarily preserve enough

Crop calendars for the US, USSR, and Canada in support of the early warning project [PDF]
New crop calendars are produced for U.S. regions where several years of periodic growth stage observations are available on a CRD basis. Preexisting crop calendars from the LACIE are also collected as are U.S.
