Moss diatoms show regional structuring, high potential endemism, and an inverse latitudinal diversity gradient in the Arctic

Ecography, Volume 2026, Issue 3, March 2026.
Microorganisms perform essential functions in Arctic terrestrial ecosystems. Yet, their ecology and biogeography are poorly understood, despite being necessary to predict microbial responses to future climate change. Here, we provide the first large‐scale floristic and biogeographic study of the moss diatom flora in the tundra regions of the North ...

Predicting potential Arctic kelp distribution and lower‐depth biomass from seafloor irradiance

Limnology and Oceanography: Methods, Volume 24, Issue 3, March 2026.
Abstract Kelps have an extensive distribution in Arctic coastal waters. However, quantifying their role in the Arctic food web and carbon cycle is challenged by the scarcity of documented geographical distribution, standing stocks and production. Here we present a framework based on an empirical function to predict the potential kelp distribution and ...

Addressing biases in sliding window analysis gives new insight into the response of parturition date to weather in a wild mammal

Oikos, Volume 2026, Issue 3, March 2026.
Animal breeding phenology in temperate and high latitude regions is often predicted by weather variables, such as temperature. Much work on this topic has focused on taxonomic groups that employ adaptive plastic responses to annual variation in an environmental cue, with analytical approaches developed to determine when weather has an effect and the ...

Glacier‐Atmosphere Interactions and Feedbacks in High‐Mountain Regions ‐ A Review

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Mountain glaciers are among the natural systems most vulnerable to climate change. However, their interactions with the atmosphere are complex and not fully understood. These interactions can trigger rapid adjustments and climate feedbacks that either amplify or attenuate atmospheric signals, influencing both glacier response and large‐scale ...

The Evolution of a Polar Cap Patch Into a Blob in the Nightside Ionosphere: Direct Observations of Multiple Blob Formation Mechanisms Acting Simultaneously on the Same Plasma

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract A polar cap patch was observed to exit the polar cap to become a blob as it entered the auroral oval on the nightside of the Earth under moderately quiet geomagnetic conditions (Kp = 3−). Auroral particle precipitation led to an increase in the electron density of the blob.

Skredsikring på Svalbard

, 2022
Etter de tragiske ulykkene på Svalbard i 2015 og 2017 ble det satt i gang omfattende arbeider for å sikre lokalbefolkningen mot skred. Det er knyttet usikkerhet til om de lokale forholdene på Svalbard gir opphav til en endring i snøens mekaniske egenskaper, sammenlignet med blant annet Fastlands-Norge og Alpelandene.

Bayesian Approach to Ionospheric Elementary Current Systems Using Differentiable Basis Functions

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Spherical elementary current systems (SECS) have become a widely used tool to model vector fields on spherical surfaces in ionospheric data analysis. The systems were originally formulated using point sources for the divergence and curl of the fields. In this paper we present a flexible alternative formulation, showing how continuous functions

Identifying Thermodynamic Regimes of CO2 Gas Exchange During the Melt Transition on First‐Year Sea Ice Using a Multi‐Sensor Synthetic Aperture Radar Approach

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Few multi‐year observations of CO2 gas exchange exist over melting first year sea ice (FYI). We report 4 years of CO2 flux data during the melt season in Dease Strait, Nunavut, Canada. Utilizing a dried, closed‐path eddy covariance system on an island within the strait, we identify two statistically distinct CO2 flux melt regimes: a pre‐pond ...

The Arctic Coastal Erosion Model: Overview, Developments, and Calibration at Drew Point, Alaska

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Permafrost coastlines are experiencing significant erosion as polar amplification has enhanced the effects of climate change in the Arctic. Warmer temperatures are increasing thermo‐denudation and more energetic oceans are increasing thermo‐abrasion in unlithified, ice‐bonded permafrost coastlines which comprise at least 40% of the circum ...

Biogeography and host associations of Russula subsection Xerampelinae based on large‐scale analysis of UNITE sequence data

New Phytologist, Volume 249, Issue 5, Page 2547-2558, March 2026.
Summary Estimating fungal geographic ranges and niche potential is limited by the ephemeral nature of fruiting bodies. While environmental DNA offers broader insights, species‐level identification remains difficult due to uncertain sequence clustering thresholds, low interspecific variation in barcoding regions, and limited taxonomic resolution.
