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 …

Elevational and polar treelines have been studied for more than two centuries. The aim of
the present article is to highlight in retrospect the scope of treeline research, scientific …

Aim To better understand how climate change drives altitudinal treeline dynamics at large
spatial scales. Location Northern Hemisphere. Time period 1901–2018. Major taxa studied …

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 …

Aim To assess the effects of climate change, past land uses and physiography on the current
position of the tree line in the C atalan P yrenees and its dynamics between 1956 and 2006 …

Willows (Salix) are some of the most abundant shrubs in cold alpine and tundra biomes. In
alpine regions, seed dispersal is not limiting upwards willow expansion, so the upslope shift …

Aim The spatial patterns of tree populations reflect multiple ecological processes. However,
little is known on whether these patterns mediate responses to climate in marginal tree …

The impact of anthropogenic global warming has induced significant upward dispersal of
trees to higher elevations at alpine treelines. Assessing vertical deviation from current …

Purpose Treelines and forest lines (TFLs) have received growing interest in recent decades,
due to their potential role as indicators of climate change. However, the understanding of …

Mountain plant communities are thought to be sensitive to climate change and, thus, able to
reveal its effects sooner than others. The status as sentinels of two plant communities are …
