Growth and carbon relations of temperate deciduous tree species at their upper elevation range limit
Armando Lenz, Auteur ; Yann Vitasse, Auteur ; Guenter Hoch, Auteur ; Christian Koerner, AuteurTemperature is one of the most important drivers of range limits in plants. Here, we aimed at disentangling the direct effect of low temperature and the indirect temperature effect via the length of the growing season on radial growth and carbon[...]
Article
Nicole Inauen, Auteur ; Christian Koerner, Auteur ; Erika Hiltbrunner, Auteur1. Large areas of alpine pastures and meadows currently face declining land use or abandonment, which leads to tall-grass transition ecosystems with higher leaf area index (LAI), potentially increased evapotranspiration (ET) and thus, reduced wa[...]

Melissa A. Dawes, Auteur ; Stephan Haettenschwiler, Auteur ; Peter Bebi, Auteur ; Frank Hagedorn, Auteur ; Ira Tanya Handa, Auteur ; Christian Koerner, Auteur ; Christian Rixen, Auteur1. Using experimental atmospheric CO(2) enrichment, we tested for tree growth stimulation at the high-elevation treeline, where there is overwhelming evidence that low temperature inhibits growth despite an adequate carbon supply. We exposed Lar[...]

Christian Koerner, AuteurDans AMBIO (41 JUL 2012)Trees are taller than shrubs, grasses, and herbs. What is the disadvantage of being tall so that trees are restricted to warmer regions than low stature life forms? This article offers a brief review of the current state of biological treeline t[...]
