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 …

Little is known about how soil properties control tree growth at its upper limit. This paper
reviews the state of knowledge and discusses the results specifically related to ecozones, to …

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

The present investigation aimed to study the regeneration status of tree species and survival
of naturally emerged seedlings along an altitudinal gradient in a protected area of Western …

Grazing by domestic ungulates can have substantial impacts on forests in arid and semi-arid
regions, possibly including severe loss of carbon from the soil. Predicting net livestock …

Andean plant species are predicted to shift their distributions, or 'migrate,'upslope in
response to future warming. The impacts of these shifts on species' population sizes and …

The Andean páramo is a biodiverse and vulnerable tropical high-mountain region, whose
spatio-ecological patterns remain understudied. The lack of general characterization of its …

Altitudinal gradients are expected to heavily influence the general performance of mountain
tree species. For this study we evaluated vitality, radial growth and reproductive efficiency in …

Studies investigating treelines in the Southern Hemisphere are underrepresented in the
global literature, with a strong bias towards Northern Hemisphere treelines. Treelines in the …

Mountain forests deserve special attention from ecologists and conservation biologists given
the ecosystem services they provide to society, and their threat under global change. In the …
