Nutrient Peak Shifts in the Arctic: Implications for Migratory Herbivores Under Climate Change

open access: yesJournal of Biogeography, Volume 53, Issue 2, February 2026.
ABSTRACT Aim Quantifying how the timing and spatial variability of Arctic vegetation nutrient peaks are projected to shift under climate change, and assessing potential consequences for migratory herbivores that rely on seasonal synchrony with peak plant quality. Location Circumpolar Arctic, with emphasis on tundra regions.

Contrasting Trends in Cold‐Season Daily Soil Temperature With Climate Warming in Snow‐Affected Settings

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Soil temperature is inextricably linked with hydrological and biogeochemical processes. This study analyzes the long‐term minimum soil temperature (TSMIN) trends at 526 stations located in snow‐affected regions of CONUS. Long short‐term memory (LSTM) are implemented to extend TSMIN beyond the observational period, producing long‐term (1981 ...

Mid‐Proterozoic Transient Oxygenation Events Linked to Enhanced Continental Chemical Weathering: Evidence From Carbonate Lithium Isotopes

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Potential drivers disrupting mid‐Proterozoic (∼1.8–0.8 Ga) environmental stasis remain poorly constrained. Here we examined carbonate Li isotopes from the ∼1.44 Ga Tieling Formation, North China, to evaluate the effects of continental chemical weathering on coeval oxygenation.

Remote Forcing of Super Typhoon Mawar on the 2023 Quebec Wildfires

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Typhoons and wildfires are major global climate and environmental hazards, yet their potential interactions remain poorly understood, particularly through remote atmospheric forcing. Taking the 2023 Quebec wildfires as an example, we investigate how a tropical cyclone can influence wildfire‐favorable conditions.

A New Climatology of Continentality Based on Lagrangian Air Mass Travel Times From the Ocean

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Climate classifications such as the Köppen classification have a long tradition and wide fields of application. An important classification aspect is continentality, for which we present a new metric based on Lagrangian dispersion model calculations.

CHARACTERISTICS OF HUMIC ACIDS OF WEST-SIBERIA PEATS

open access: yesВестник Кемеровского государственного университета, 2014
The paper aims at characterizing the humic acids (HA) of representative peats, selected by V. N. Efimova and M. G. Vasilkova’s method. The botanical composition of the Tomsk region peats is given. On the basis of elemental analysis, 13C-NMR, EPR and infra-red spectroscopy of HA the features of their structures are revealed.
