Conifer mountain forests influence numerous human populations by providing a host of
critical economic, sociological, and ecosystem services. Although the causes of the …

Recent hypotheses of timberline causation include the possibility that limitations to growth
processes may be more limiting than restrictions on photosynthetic carbon gain, and that …

Although climate warming is generally expected to facilitate upward advance of forests,
conifer seedling regeneration and survival may be hindered by low substrate moisture, high …

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 …

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 …

Background: Seedling germination and survival is a critical control on forest ecosystem
boundaries, such as at the alpine–treeline ecotone. In addition, while it is known that …

Treeline advance has occurred throughout the twentieth century in mountainous regions
around the world; however, local variation and temporal lags in responses to climate …

The importance of seedling establishment to the position ofalpine-treeline is recognized, yet
little is known about factorsaffecting the survival of seedlings of treeline conifers during their …

Understanding plant–plant facilitation is critical for predicting how plant community function
will respond to changing disturbance and climate. In longleaf pine (Pinus palustris Mill.) …

Seedling stage has long been recognized as the bottleneck of forest regeneration, and the
biotic and abiotic processes that dominate at seedling stage largely affect the dynamics of …
