Examining Drivers of Post-Fire Seismic Line Ecotone Regeneration in a Boreal Peatland Environment

, 2023
Seismic lines are the dominant anthropogenic disturbance in the boreal forest of the Canadian province of Alberta, fragmenting over 1900 km2 of peatland areas and accounting for more than 80% of all anthropogenic disturbance in this region.

Wildlife species benefitting from a greener Arctic are most sensitive to shrub cover at leading range edges

, 2017
Widespread expansion of shrubs is occurring across the Arctic. Shrub expansion will substantially alter arctic wildlife habitats. Identifying which wildlife species are most affected by shrubification is central to predicting future arctic community ...

Rhizosphere bacteria and fungi are differentially structured by host plants, soil mineralogy, and ectomycorrhizal communities in the Alaskan Tundra

Arctic Science
The rhizosphere contains diverse groups of bacteria and fungi living near plant roots and mycorrhizal hyphae whose composition and function are key drivers of ecosystem and biogeochemical processes.

High-latitude vegetation shifts in the era of global change: Multi-decade ecosystem-level evidence from Northern Europe

Nordia Geographical Publications
Biodiversity is increasingly threatened by human-induced global change drivers that restructure ecosystems. High-latitude ecosystems are particularly vulnerable to climate change, which alters vegetation composition, diversity, and functioning. However,

Introducing shrubs enhances the representation of high-latitude vegetation and carbon cycling in the ORCHIDEE land surface model [PDF]

Biogeosciences
Arctic–Boreal terrestrial ecosystems are rapidly changing under amplified high-latitude warming, including widespread expansion of shrubs, with consequences for regional carbon and energy balances.

Remotely Piloted Aircraft Systems (RPAS) for Monitoring Archaeological Sites in Nunavik in the Face of a Changing Climate

Canadian Journal of Remote Sensing
Over the last century, remote sensing has proven effective in recognizing and studying cultural heritage in various geographic and chronological contexts, and the use of Remotely Piloted Aircraft Systems (RPAS) has become an integral part of ...

DRIVING FACTORS AND SPATIAL PATTERNS OF SHRUBIFICATION: A CASE STUDY OF ALDER THICKETS IN THE SOUTHERN TUNDRA OF WESTERN SIBERIA

Russian Journal of Ecosystem Ecology
The shrub expansion of the tundra is one of the key processes transforming Arctic ecosystems under climate warming. Alder thickets play a significant role in this process. However, their phytocenotic structure and associated soil changes in the southern tundra of Western Siberia remain poorly understood.

Arktisen vuoristotundran pensastumisen vaikutus ympäröivään kasvillisuuteen ja maaperän kosteus -ja lämpötilaoloihin [PDF]

, 2018
Arktiselle alueelle kohdistuu ilmaston lämmetessä huomattava sopeutumispaine ja viileissä ilmastoissa keskeinen kasvillisuuden vaste on ikivihreiden pensasmaisten lajien levinneisyysalueen kasvu. Pensaiden määrän ennustetaan lisääntyvän 50 % vuoteen 2050
