Aim Climatic conditions exert a strong control on the geographic distribution of many
woodland‐to‐grassland transition zones (or 'tree lines'). Because woody plants have, in …

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 …

Most ecologists are not card-carrying members of either individualistic or interdependent
guilds, but our perception of plant community organization, and the way we conduct …

Climate niche models project that subalpine forest ranges will extend upslope with climate
warming. These projections assume that the climate suitable for adult trees will be adequate …

Many tropical alpine treelines lie below their climatic potential, because of natural or
anthropogenic causes. Forest extension above the treeline depends on the ability of trees to …

Although the ecological dynamics of the alpine treeline ecotone are influenced by climate, it
is an imperfect indicator of climate change. Mechanistic processes that shape the ecotone …

Dense herbaceous understorey layers can impact tree regeneration and thereby affect forest
succession. However, the implications of this interaction on large spatial and temporal …

Understanding processes controlling forest dynamics has become particularly important in
the context of ongoing climate change, which is altering the ecological fitness and resilience …

Tree establishment is a potentially important factor affecting tree populations in alpine-
treeline ecotones. Patterns of seedling establishment of Abies lasiocarpa, Pinus albicaulis …

Context Ecotones are boundary zones formed where overlap between neighboring
ecosystems creates an intermediate ecosystem with unique ecological characteristics …
