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 …

In the absence of broad‐scale disturbance, many temperate coniferous forests experience
successful seedling establishment only when abundant seed production coincides with …

Significant treeline advance can only occur with successful establishment, growth, and
survival of new seedlings. Several studies have examined microsite factors at single …

Alpine treelines are expected to move upslope with a warming climate. However, so far
treelines have responded inconsistently and future shifts remain difficult to predict since …

Microsites, local features having the potential to alter the environment for seedling
regeneration, may help to define likely trends in high-elevation forest regeneration pattern …

Questions We investigated the importance of climate and herbivory on native and alien
conifer colonization of the birch‐dominated Fennoscandian tree line by addressing the …

Subject to a long research tradition, the tree line is considered an important biogeographic
indicator of climate changes and associated range shifts. Realized tree line positions and …

In some internal valleys of the northern Andes, precipitation at treeline elevation is seasonal,
with one or two dry periods that could exert a strong control on tree seedling survival …

The sensitivity and response of climatic treelines in the Himalayas to climate change is still
being debated. Regeneration of tree species in the treeline ecotone is considered a …

Fine-scale disturbance can increase seed access to suitable substrates, facilitating
germinant emergence and survival, which are necessary elements for treeline advance. We …
