Open‐top designs for manipulating field temperature in high‐latitude ecosystems
Passive open‐top devices have been proposed as a method to experimentally increase temperature in high‐latitude ecosystems. There is, however, little documentation on the efficacy of these devices.…

Warming increased height and cover of deciduous shrubs and graminoids, decreased cover of mosses and lichens, and decreased species diversity and evenness, which predict that warming will cause a decline in biodiversity across a wide variety of tundra, at least in the short term.
RESPONSES OF TUNDRA PLANTS TO EXPERIMENTAL WARMING:META‐ANALYSIS OF THE INTERNATIONAL TUNDRA EXPERIMENT
Results indicate that key phenological events such as leaf bud burst and flowering occurred earlier in warmed plots throughout the study period; however, there was little impact on growth cessation at the end of the season.
Global assessment of experimental climate warming on tundra vegetation: heterogeneity over space and time.
The results indicate that tundra vegetation exhibits strong regional variation in response to warming, and that in vulnerable regions, cumulative effects of long-term warming on tundRA vegetation - and associated ecosystem consequences - have the potential to be much greater than the authors have observed to date.
Tundra plants and climate change: the International Tundra Experiment (ITEX)
The International Tundra Experiment (ITEX) was established in late 1990 at a meeting of arctic tundra ecologists as a response to predictions that the human‐enhanced greenhouse warming would occur…
Plot-scale evidence of tundra vegetation change and links to recent summer warming.
Temperature is increasing at unprecedented rates across most of the tundra biome(1). Remote-sensing data indicate that contemporary climate warming has already resulted in increased productivity ov…
Continent-wide response of mountain vegetation to climate change
Climate impact studies have indicated ecological fingerprints of recent global warming across a wide range of habitats1, 2. Although these studies have shown responses from various local case…
Recent Plant Diversity Changes on Europe’s Mountain Summits
Recent changes in vascular plant species richness observed in a standardized monitoring network across Europe’s major mountain ranges are presented and indicate that high-altitude species, and in particular the rich endemic alpine flora of many Mediterranean mountain ranges, will come under increasing pressure in the predicted warmer and drier climates in this region.
Global negative vegetation feedback to climate warming responses of leaf litter decomposition rates in cold biomes.
It is demonstrated that longer-term, large-scale changes to leaf litter decomposition will be driven primarily by both direct warming effects and concomitant shifts in plant growth form composition, with a much smaller role for changes in litter quality within species.
Relationships between flowering phenology and life history strategies in tundra plants.

Temperate plants show high correlations between life history strategies, mating systems, and mating systems in terms of pollen: ovules, seed: ovule, and fruit: flower ratios.
