Climate change is causing extensive alterations to ecosystems globally, with some more
vulnerable than others. Alpine ecosystems, characterised by low-temperatures and …

Climate warming is expected to induce treelines to advance to higher elevations. Empirical
studies in diverse mountain ranges, however, give evidence of both advancing alpine …

High-elevation trees cannot always reach the thermal treeline, the potential upper range
limit set by growing-season temperature. But delineation of the realized upper range limit of …

The alpine treeline is commonly regarded as being sensitive to climatic warming because
regeneration and growth of trees at treeline generally are limited by low temperature. The …

Among forest ecosystems, the alpine treeline ecotone can be considered to be a simplified
model to study global ecology and climate change. Alpine treelines are expected to shift …

Birch (Betula) trees and forests are found across much of the temperate and boreal zones of
the Northern Hemisphere. Yet, despite being an ecologically significant genus, it is not well …

Global climate change affects the soil microbial community assemblages of many
ecosystems. However, little is known about the effects of climate warming on the structure of …

Treeline shifting in tandem with climate change has widely been reported from various parts
of the world. In Nepal, several impacts of climate change on the physical environment have …

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 …

Physiological and ecological mechanisms that define treelines are still debated. It has been
suggested that the absence of trees above the treeline is caused by low temperatures that …
