Kent et al. just published a #newarticle and found that Arctic warming and ice-wedge degradation results in a loss of shrubs and a shift towards aquatic moss-dominated vegetation communities. This moss proliferation may be an important climate feedback: 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...

#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

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. Further, previous studies of shrub tundra passerines h...

Plant community nutrient levels and soil biogeochemical responses to sixty-plus years of brown lemming exclusion in Utqiaġvik, Alaska
Small mammal herbivores are crucial drivers of Arctic ecosystem functions, but responses to herbivory depend on context such as land cover and study length. We examined the long-term effects (more ...
