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 ...

Study of Chemical and Optical Properties of Biomass Burning Aerosols during Long-Range Transport Events toward the Arctic in Summer 2017

Atmosphere, 2020
Biomass burning related aerosol episodes are becoming a serious threat to the radiative balance of the Arctic region. Since early July 2017 intense wildfires were recorded between August and September in Canada and Greenland, covering an area up to 4674 ...

Growth in Production and Environmental Deposition of Trifluoroacetic Acid Due To Long‐Lived CFC Replacements and Anesthetics

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Trifluoroacetic acid (TFA) is a persistent pollutant with potential long‐term effects on the environment and on health. Recent studies using ice core records report large increases (up to tenfold) in Arctic TFA deposition since the 1970s, and trends suggest long‐lived chlorofluorocarbon (CFC) replacements may be a major source.

Svalbard as a study model of future High Arctic coastal environments in a warming world

Oceanologia, 2017
Svalbard archipelago, a high latitude area in a region undergoing rapid climate change, is relatively easily accessible for field research. This makes the fjords of Spitsbergen, its largest island, some of the best studied Arctic coastal areas.

Population Genomic Structure and Demographic History of Black Guillemots Breeding Across the North Atlantic

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Identifying distinct genetic populations is important for successful species conservation and management. We used double‐digest restriction‐site associated DNA sequencing (ddRADseq) to look at how 172 black guillemots from different regions in the Arctic and North Atlantic oceans differed genetically.

Reconstructing Environmental and Microbial Ecosystem Changes Across the Permian–Triassic Mass Extinction at Lusitaniadalen, Svalbard

Paleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract The Permian–Triassic environmental crisis triggered fundamental changes in marine ecosystems, culminating in the most severe biodiversity crisis of the Phanerozoic. Yet, the environmental and geochemical conditions governing the crisis and ecosystem recovery remain debated.
