Kopalová et. al. published a #newarticle that explores bacterial and diatom diversity in waterbodies across the Antarctic Peninsula. They found significant differences in bacterial, but not diatom, communities: doi.org/10.1080/1523...

Glacier meltwater streams can act as both a carbon sink and source, releasing methane but storing carbon dioxide through mineral weathering. Ragnoli et al.’s #newarticle explores this source and sink behavior in the Eastern Alps: doi.org/10.1080/1523...

Hotaling et al.’s #newarticle took them to Paradise Glacier on the south side of Mount Rainier to collect and study glacial ice worms. Despite living in ice, these worms cannot tolerate freezing: doi.org/10.1080/1523...

Rock glaciers, found in warmer, drier environments than alpine glaciers, are relatively common but their distribution and number are not well known. Fountain et al.’s #newarticle identified 2,257 rock glaciers and their importance to the American West: doi.org/10.1080/1523...

Ice-capped mountains in the western United States are shrinking due to climate change. Hotaling et al. surveyed five of these summits in Washington state and published a #newarticle detailing their findings: doi.org/10.1080/1523...

Check out Thomas Ager’s #newarticle that uses a pollen analysis to reconstruct the landscape and climate of western Alaska during and after the Late Glacial Maximum. Turns out the area was drier and colder than it is today: doi.org/10.1080/1523....

#newarticle Ray & Vidrio analyze the longest study of American pika population dynamics & find dramatic decline in juvenile recruitment within a core of the species' range. Warming summers may reduce the successful dispersal of juveniles even at high elevations: doi.org/10.1080/15230430.2025.2570526

The Ray & Vidrio 2025 pika paper was published in INSTAAR's peer-reviewed journal "Arctic, Antarctic, and Alpine Research" @aaarjournal.bsky.social

Calcareous glacier forefields harbor a rich diversity of Mortierellaceae, typical for high alpine environments. In a #newarticle, Szedlacsek et al. discover that so far undescribed lineages could be isolated from the mountain-sites of Marmolada: doi.org/10.1080/15230430.2025.2555628

#newarticle Hersberger et al.’s paleoecological study of the Pindos Mountains, northern Greece, reports that transhumant pastoralism might have been practiced since at least the Late Bronze Age, possibly the Neolithic, much earlier than previously thought: doi.org/10.1080/15230430.2025.2545038

Comparative use of alder, birch, and upright willow shrubs by passerines in above–tree line regions of Arctic and sub-Arctic Alaska Assessments of passerine–habitat relationships in shrub tundra regions are rare, limiting our understanding of the effects of shrub expansion.
