J. Mizel’s #newarticle studying shrub tundra passerines assesses that the density of shrub-adapted passerines in above-treeline regions of Alaska responds positively to alder and upright willow shrub cover but weakly to birch shrub cover: doi.org/10.1080/15230430.2025.2546175

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...

In a #newarticle, Uccello et al. demonstrate that decades of small mammal herbivore exclusion drive plant community nutrient changes in a Northern Alaskan tundra. This work also shows the importance of including bryophytes in Arctic nutrient research: doi.org/10.1080/15230430.2025.2532885

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 ...
