Patterns of free amino acids in tundra soils reflect mycorrhizal type, shrubification, and warming. [PDF]
Mycorrhiza, 2022 AbstractThe soil nitrogen (N) cycle in cold terrestrial ecosystems is slow and organically bound N is an important source of N for plants in these ecosystems. Many plant species can take up free amino acids from these infertile soils, either directly or indirectly via their mycorrhizal fungi. We hypothesized that plant community changes and local plant

, 2021 Permafrost is warming globally and the extent of this warming is locally variable in space and time due to an array of factors. In the Arctic, vegetation is one of these factors, whichever influenced by climate change is undergoing a transformation through an increase in height and extent of shrubs on the tundra.

Terrestrial Arthropod Responses to Arctic Cryosphere Degradation. [PDF]
Glob Chang BiolChanges in Arctic snow and ice are impacting terrestrial arthropods—for example, thinner snowpacks alter phenological synchrony and soil fauna survival; thawing permafrost increases decomposition, and glacial ice loss leads to the disappearance of adapted specialists; sea ice decline will have many indirect impacts for arthropods.

Simulated rhizosphere deposits induce microbial N‐mining that may accelerate shrubification in the subarctic [PDF]
Ecology, 2020 AbstractClimate change is exposing high‐latitude systems to warming and a shift towards more shrub‐dominated plant communities, resulting in increased leaf‐litter inputs at the soil surface, and more labile root‐derived organic matter (OM) input in the soil profile.

Implications of alder shrub growth for alpine tundra soil properties in Interior Alaska
Arctic, Antarctic, and Alpine Research, 2023 The increase in deciduous shrub growth in response to climate change throughout the Arctic tundra has uncertain implications, in part due to a lack of field observations.

Shrubification of peatlands [PDF]
Science, 2020 Biogeography Soil is a key player in the global carbon cycle. Peatlands are important because they contain more than half of global soil carbon, much of which is sequestered in slow-decaying Sphagnum moss. Hence, there is a need to understand how peatlands will respond to the rapidly changing climate. Malhotra et al.

Environmental Research Letters, 2021 Global warming leads to drastic changes in the diversity and structure of Arctic plant communities. Studies of functional diversity within the Arctic tundra biome have improved our understanding of plant responses to warming. However, these studies still

Environmental Research Letters, 2021 Plant growth and distribution in high-latitude tundra ecosystems is strongly limited by nutrient availability and is critical for quantifying centennial-scale carbon-climate interactions. However, land model representations of plant–nutrient interactions

Rapid Ecosystem Change at the Southern Limit of the Canadian Arctic, Torngat Mountains National Park
Remote Sensing, 2021 Northern protected areas guard against habitat and species loss but are themselves highly vulnerable to environmental change due to their fixed spatial boundaries.

Environmental Research Letters, 2020 Vegetation is responding to climate change, which is especially prominent in the Arctic. Vegetation change is manifest in different ways and varies regionally, depending on the characteristics of the investigated area.
