Soil temperatures near the distribution limit of the mountain birch (Betula pubescens ssp. czerepanovii): implications for seedling nitrogen economy and survival.
TLDR
In this article, the authors describe soil temperature conditions in an area close to the altitudinal and latitudinal distribution limit of the mountain birch and evaluate whether soil temperature is like...Abstract:

A world-wide study of high altitude treeline temperatures
Christian Körner,Jens Paulsen +1 more
TL;DR: At a coarse scale, the treelines of the world's mountains seem to follow a common isotherm, but the evidence for this has been indirect so far, so this work aims at underpinning this with facts.
Journal ArticleDOI
Altitudinal increase of mobile carbon pools in Pinus cembra suggests sink limitation of growth at the Swiss treeline
TL;DR: In this article, the authors analyzed mobile carbon pools in Pinus cembra across the treeline ecotone in the Swiss Alps and concluded that carbon limitation is not responsible for reduced tree growth at the alpine treeline.
Journal ArticleDOI
Another perspective on altitudinal limits of alpine timberlines
TL;DR: A conceptual model of timberline migration is described that invokes a strong dependence on ecological facilitation, beginning with seed germination and continuing through seedling establishment and sapling growth to the stage where trees with forest-like stature form new subalpine forest at a higher altitude.
Journal ArticleDOI
Treeline advance - driving processes and adverse factors
TL;DR: In this article, the effects of varying topography on site conditions and the after-effects of historical disturbances by natural and anthropogenic factors may override the effect of slightly higher average temperatures.
Journal ArticleDOI
Growth response of Mountain birch to air and soil temperature: is increasing leaf-nitrogen content an acclimation to lower air temperature?
Martin Weih,P. S. Karlsson +1 more
TL;DR: In this paper, the growth and nitrogen economy of mountain birch (Betula pubescens ssp. czerepanovii) seedlings were reported in response to temperature change.

A re-assessment of high elevation treeline positions and their explanation
TL;DR: It is hypothesized that the life form “tree” is limited at treeline altitudes by the potential investment, rather than production, of assimilates (growth as such,rather than photosynthesis or the carbon balance, being limited), and root zone temperature, though largely unknown, is likely to be most critical.

Temperature and plant species control over litter decomposition in Alaskan tundra
Sarah E. Hobbie,Sarah E. Hobbie +1 more
TL;DR: In this paper, the effects of increased temperature and litter from different Alaskan tundra plant species on cycling of carbon and nitrogen through litter and soil in microcosms were compared.
Journal ArticleDOI
Arctic ecosystems in a changing climate : an ecophysiological perspective
TL;DR: In this paper, the authors studied the potential for change in the Arctic Flora and Vegetation in a changing climate, and proposed a model for the response of Arctic plants to changing climate.
Journal ArticleDOI
The nutritional status of plants from high altitudes : A worldwide comparison
TL;DR: In this article, the mineral nutrient content of leaves from over 150 plant species from 9 different mountain areas of all major climatic zones were analyzed (Kjeldahl nitrogen in all, phosphate in half of the samples, K, Mg, Mn, Ca in the Alps only).
Journal ArticleDOI
Interspecific and intraspecific variation in tree seedling survival: effects of allocation to roots versus carbohydrate reserves.
TL;DR: There was an approximately linear relationship between carbohydrate reserves and subsequent survival, but no clear relationship between allocation to root structural biomass and subsequent Survival.
