Potential Warming‐Induced Changes in Stream Water Sources Between Proglacial and Non‐Glacial Streams, South‐Central Alaska

Hydrological Processes, Volume 40, Issue 8, August 2026.
Land cover and elevation are shown to influence the proportion of stream source waters across glacial and non‐glacial streams. Groundwater makes up a large proportion of both early season and late season flow in most glacial and non‐glacial streams, while the timing of snow and ice melt is driven by the presence or absence of a glacier within the ...

Long-term decomposition of above- and below-ground tissue of two Arctic shrub species

Arctic Science
Arctic soils may become a major source of greenhouse gas emissions, as the climate changes. It is thus crucial to understand decomposition dynamics of permafrost soils, which are influenced by a myriad of abiotic and biotic factors including changing ...

Between birch and berries: seasonal dietary niche partitioning among sympatric alpine herbivorous birds

Oikos, Volume 2026, Issue 8, August 2026.
Niche partitioning is important for the coexistence of closely related species, allowing species to reduce overlap in resource use despite shared ecological requirements. In alpine environments, harsh climatic conditions and low habitat complexity constrain opportunities for ecological segregation, making seasonal resource fluctuation especially ...

Lacking data? No worries! How synthetic images can alleviate image scarcity in wildlife surveys: A case study with muskox (Ovibos moschatus)

Remote Sensing in Ecology and Conservation, Volume 12, Issue 4, Page 593-610, August 2026.
This study investigates the integration of synthetic imagery, created with diffusion‐based models, to supplement limited training data and improve muskox (Ovibos moschatus) detection in zero‐shot (ZS) and few‐shot (FS) settings. ZS models detected more than 80% of muskoxen in real images, confirming the potential of synthetic data as a substitute for ...

Assessing the Vulnerability of an Inuit Archaeological Site in a Changing Periglacial Environment: A Novel Multimethod Geophysical Approach in Arctic Geoarchaeology

Archaeometry, Volume 68, Issue 4, Page 620-632, August 2026.
ABSTRACT With northern regions warming at twice the global rate, assessing the state of archaeological sites in these areas is critically important. In this study, we used a multimethod geophysical approach (ERT, GPR, and EMI) to characterize the current geocryological conditions of an Inuit archaeological site on South Aulatsivik Island (Labrador ...

Alpine flora of Kashmir Himalaya: floristic assessment, life history traits and threat status

Nordic Journal of Botany, Volume 2026, Issue 7, July 2026.
Alpine ecosystems in the Himalaya are considered to be at a higher risk to anthropogenic global change drivers. The Kashmir Himalaya, located in the north‐western side of the Himalayan biodiversity hotspot, harbors a diverse alpine flora, which remains systematically little investigated.

Shrub Expansion Can Counteract Carbon Losses From Warming Tundra [PDF]

Arctic warming is causing substantial compositional, structural, and functional changes in tundra vegetation including shrub and tree‐line expansion and densification.

Multi-index analysis reveals complexity of tundra greening and shrubification on Yamal Peninsula

Environmental Research: Ecology
Arctic vegetation cover is undergoing rapid structural and spatial change under a warming climate. Shrubification is a major component of these changes, whereby shrubs grow outwards and upwards, infilling existing patches and spreading into new areas ...

Harmonising digitised herbarium data to enhance biodiversity knowledge: Major steps towards an updated checklist for the flora of Greenland

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1195-1209, July 2026.
Herbaria worldwide hold centuries of plant data that are key to understanding and protecting biodiversity; however, even with increased digital access, differences in plant naming systems make it difficult to compare records. We developed a semi‐automated workflow that standardises species names and organises herbaria records from multiple institutions
