Snow is an important driver of ecosystem processes in cold biomes. accumulation determines ground temperature, light conditions, and moisture availability during winter. It also affects the growing season’s start end, plant access to nutrients. Here, we review current knowledge snow cover’s role for vegetation, plant-animal interactions, permafrost microbial processes, biogeochemical cycling. We compare studies natural gradients with experimental manipulation assess time scale difference...
Abstract Arctic and alpine tundra ecosystems are large reservoirs of organic carbon 1,2 . Climate warming may stimulate ecosystem respiration release into the atmosphere 3,4 The magnitude persistency this stimulation environmental mechanisms that drive its variation remain uncertain 5–7 This hampers accuracy global land carbon–climate feedback projections 7,8 Here we synthesize 136 datasets from 56 open-top chamber in situ experiments located at 28 arctic sites which have been running for...
The subarctic region is highly responsive and vulnerable to climate change. Understanding the structure of soil microbial communities essential for predicting response environment To determine composition bacterial community its relationship with properties, we investigated properties surface from moist acidic tussock tundra in Council, Alaska. We collected 70 samples 25-m intervals between sampling points 0–10 cm 10–20 depths. was analyzed by pyrosequencing 16S rRNA genes, following were...
Primary succession after glacier retreat has been widely studied in plant communities, but bacterial is still poorly understood. In particular, few studies of microbial have performed the Arctic. We investigated shifts community structure and soil physicochemical properties along a successional gradient 100-year foreland High Multivariate analyses revealed that time played key role associated during succession. However, environmental filtering (i.e. pH temperature) also accounted for...
Permafrost-underlain tundra soils in Northern Hemisphere are one of the largest reservoirs terrestrial carbon, which highly sensitive to microbial decomposition due climate warming. However, knowledge about taxonomy and functions microbiome residing different horizons permafrost-underlain is still limited. Here we compared taxonomic functional composition between soil cores from a moist tussock ecosystem Council, Alaska, using 16S rRNA gene shotgun metagenomic sequencing. The composition,...
Permafrost soils store vast amounts of organic carbon, and their thawing due to climate warming accelerates the release carbon as methane dioxide, exacerbating global change. Understanding distribution greenhouse gases trapped in these predicting behavior upon is essential for accurately modeling feedbacks. This study presents an integrated biogeochemical microbial dataset from ~1.8 m deep soil cores collected across a 970 km latitudinal gradient Alaskan permafrost regions, spanning boreal...
Abstract In this study, we analyzed the effects of snow cover changes caused by fences (SFs) installed in 2017 Alaskan tundra to examine ground subsidence. Digital surface model data obtained through LiDAR-based remote sensing 2019 and 2022, combined with a field survey 2021, revealed approximately 0.2 m subsidence around SF. To investigate relationship between SF-induced subsidence, geophysical methods, electrical resistivity tomography (ERT) ground-penetrating radar (GPR), were applied...
Abstract Over the past few decades Arctic has warmed up more than lower latitudes. Soil organic carbon (SOC) in is vulnerable to climate change, and dioxide (CO 2 ) produced via SOC decomposition can amplify atmospheric temperature increase. Although composition relevant decomposability, studies on its compositional changes with warming are scarce, particularly Arctic. Therefore, we investigated responses of bacterial community manipulation under Cassiope Salix heath vegetation communities...
