Alpine and Arctic treeline expansion depends on establishment of tree seedlings beyond the
current treeline, which is expected to occur with climate warming. However, treelines often …

Abstract Background The Republic of Georgia (Sakartvelo in Georgian language) is part of
the Caucasus biodiversity hotspot, and human agricultural plant use dates bat at least 6000 …

Christian Körner has been at the forefront of research investigating treelines, and in the late
1990s and early 2000s he proposed a unifying theory to explain the global occurrence of …

The previous chapters have provided a first insight into the heterogeneity, complexity and
great physiognomic and ecological variety of the timberline phenomenon; a heterogeneity …

In this study, we documented traditional plant use in Tusheti, Khevsureti, and Pshavi and
hypothesized that (i) plant use knowledge in general would be higher in isolated high …

Globally, treeline ecotones vary from abrupt lines to extended zones of increasingly small,
stunted and/or dispersed trees. These spatial patterns contain information about the …

Aims Alpine tree line ecotones are harsh environments where low temperatures constrain
tree regeneration and growth. However, the expected upward shift of tree line ecotones in …

Spatial fingerprints of climate change on tree species distribution are usually detected at
latitudinal or altitudinal extremes (arctic or alpine tree line), where temperatures play a key …

For over 100 years, mountain treelines have been the subject of varied research endeavors
and remain a strong area of investigation. The purpose of this paper is to examine aspects of …

The alpine treeline is shifting upward due to climate warming. However, the treeline species
composition and the pace of its upward migration can be mediated by ecological …
