A serological survey of zoonotic infections in Yakutia

Якутский медицинский журнал
The article analyzes the outcomes of three field surveys concerning the seroepidemiology of various zoonoses in the Sakha Republic (Yakutia). These studies were carried out from 2007 to 2018 in Artic (Verkhoyansk area) and subarctic (Vilyuysk area then ...

Quantifying Changing Groundwater Exfiltration at a High Arctic Site due to Climate Change

Hydrological Processes, Volume 39, Issue 8, August 2025.
To understand how climate change is affecting northern hydrology, we use a combination of climate model results and numerical groundwater models to project future groundwater discharge rates to an arctic lake. We find that the active layer thickens and stays open longer, leading to increased groundwater flow to the lake.

Probable multi-year trends of degradation of post-pyrogenic forest soils in Russia

Бюллетень Почвенного института им. В.В. Докучаева
A comparison of soil-geographical units of the Unified State Register of Soils of Russia with a database on the disappearance of woody forest vegetation for the period from 2000 to 2021, built on Landsat satellite data, made it possible to identify soil ...

Surface displacement revealed by L-band InSAR analysis in the Mayya area, Central Yakutia, underlain by continuous permafrost

Earth, Planets and Space, 2020
Recent increases in global temperature have stimulated permafrost degradation associated with landform deformation caused by the melting of excess ground ice (thermokarst).

Vegetation and environmental dynamics in the central part of the Kola Peninsula during the past 13.3 ka as reflected by ancient plant DNA on sediments from Lake Imandra

Journal of Quaternary Science, Volume 40, Issue 6, Page 1070-1096, August 2025.
ABSTRACT The first high‐resolution reconstruction of the vegetation and environmental changes during the last ca 13 300 cal a BP in the central part of the Kola Peninsula (NW Russia) was reconstructed based on sedimentary ancient DNA (sedaDNA) metabarcoding on sediment core Co1410 from Lake Imandra.

Environmental changes on the northern Taymyr Peninsula (Russian Arctic) during the last 62 ka inferred from the lacustrine pollen record

Boreas, Volume 54, Issue 3, Page 431-446, July 2025.
Environmental changes on the northern part of Taymyr Peninsula during the last 62 ka were reconstructed based on pollen assemblages throughout a 46‐m‐long sediment core from Lake Levinson‐Lessing (74°27′54″N, 98°39′58″E). Environmental changes on the northern Taymyr Peninsula were reconstructed based on a new pollen record from a 46‐m‐long sediment ...

Picroilmenite from Kimberlite Pipes of Central Yakutia

IOP Conference Series: Earth and Environmental Science, 2020
Abstract Picroilmenite is one of the most important indicator minerals of kimberlite rocks, which can be used in solving petrological problems and in the search for diamond deposits. The present study shows the results of studying picroilmenite grains from the Manchary and Aprelskaya pipes within the Khompu-May kimberlite field (Central ...

Hydroclimatic development from the Early Holocene to anthropogenic times: a comparative study of diatom oxygen isotope records and multiproxy data from Lake Khamra, eastern Siberia

Boreas, Volume 54, Issue 3, Page 447-467, July 2025.
Northern Eurasia underwent major hydroclimatic changes since the beginning of the Holocene interglacial. A rapid warming period reaching the Holocene Thermal Maximum (HTM), followed by a general cooling trend until recent times, was observed in Eurasian lacustrine diatom oxygen isotope (δ18Odiatom) records.

Hepatic Phenotype in NBAS‐Associated Disease: Clinical Course, Prognostic Factors and Outcome in 230 Patients

Liver International, Volume 45, Issue 7, July 2025.
ABSTRACT Background and Aims Since described in 2015, NBAS‐associated disease has emerged as an important cause of acute liver failure (ALF) in children. We analysed the variable expression, genotype–phenotype association, outcome and prognostic factors of the hepatic involvement.

Thermokarst Lakes in Central Yakutia (Siberia) as Habitats of Freshwater Ostracods and Archives of Palaeoclimate [PDF]

, 2008
Thermokarst lake deposits are useful archives of climatic and environmental changes in the past, and can contain palaeo-bioindicators such as pollen, plant macro-fossils, diatoms, chironomids and also ostracods. Nevertheless, such studies from permafrost
