Nomenclature adjustments and new syntaxa of the arctic, alpine and oro-Mediterranean vegetation [PDF]

open access: yes, 2015
Proposte sintassonomiche e nomenclaturali per la vegetazione della Tundra alpina. Il capitolo riguardante l'alta quota appenninica è il più corposo e propone il nuovo syntaxon Leontopodio-Elynion a livello di alleanza.

Spatio-temporal influence of tundra snow properties on Ku-band (17.2 GHz) backscatter [PDF]

open access: yes, 2015
During the 2010/11 boreal winter, a distributed set of backscatter measurements was collected using a ground-based Ku-band (17.2 GHz) scatterometer system at 26 open tundra sites.

Differential arthropod responses to warming are altering the structure of Arctic communities [PDF]

open access: yesRoyal Society Open Science, 2018
The Arctic is experiencing some of the fastest rates of warming on the planet. Although many studies have documented responses to such warming by individual species, the idiosyncratic nature of these findings has prevented us from extrapolating them to ...

Greening on the Bathurst caribou range in northern Canada: are erect shrubs responsible for remotely sensed trends?

open access: yesArctic Science, 2023
Remote sensing has detected recent trends of increased vegetation productivity on the Bathurst caribou herd’s range. The cause of this spectral greening is unknown but is hypothesized to be the result of a change in the composition, establishment ...

Relationship of cyanobacterial and algal assemblages with vegetation in the high Arctic tundra (West Spitsbergen, Svalbard Archipelago)

open access: yesPolish Polar Research, 2015
The paper presents the results of a study of cyanobacteria and green algae assemblages occurring in various tundra types determined on the basis of mosses and vascular plants and habitat conditions. The research was carried out during summer in the years

Warming-induced permafrost thaw exacerbates tundra soil carbon decomposition mediated by microbial community

open access: yesMicrobiome, 2020
It is well-known that global warming has effects on high-latitude tundra underlain with permafrost. This leads to a severe concern that decomposition of soil organic carbon (SOC) previously stored in this region, which accounts for about 50% of the world’

Effects of multiple environmental variables on tundra ecosystem respiration in maritime Antarctica

open access: yesScientific Reports, 2018
Summertime ecosystem respiration (ER) rates through seven sites were measured at an upland tundra on Fildes Peninsula in maritime Antarctica to investigate effects of topographic gradient, vegetation types and climatic factors on tundra ER rates. Overall

Impacts of active retrogressive thaw slumps on vegetation, soil, and net ecosystem exchange of carbon dioxide in the Canadian High Arctic

open access: yesArctic Science, 2017
Retrogressive thaw slumps (RTS) are permafrost disturbances common on the Fosheim Peninsula, Ellesmere Island, Canada. During the 2013 growing season, three different RTS were studied to investigate the impact on vegetation composition, soil, and growing

Global plant trait relationships extend to the climatic extremes of the tundra biome

open access: yesNature Communications, 2020
The majority of variation in six traits critical to the growth, survival and reproduction of plant species is thought to be organised along just two dimensions, corresponding to strategies of plant size and resource acquisition.

Earlier snowmelt may lead to late season declines in plant productivity and carbon sequestration in Arctic tundra ecosystems

open access: yesScientific Reports, 2021
Arctic warming is affecting snow cover and soil hydrology, with consequences for carbon sequestration in tundra ecosystems. The scarcity of observations in the Arctic has limited our understanding of the impact of covarying environmental drivers on the ...
