Abstract Ecosystems in the North American Arctic-Boreal Zone (ABZ) experience a diverse
set of disturbances associated with wildfire, permafrost dynamics, geomorphic processes …

The boreal zone of Alaska is dominated by interactions between disturbances, vegetation,
and soils. These interactions are likely to change in the future through increasing permafrost …

Abstract Ecosystems across the United States are changing in complex and unpredictable
ways and analysis of these changes requires coordinated, long‐term research. This paper is …

During foraging, moose break stems of numerous saplings in order to lower shoot tips to a
height they can reach. Both stem-breaking and bedding occur throughout the range of …

Changed disturbance regimes could drive biome-level shifts in vegetation structure and
have cascading societal consequences. Expanding and intensifying bark beetle outbreaks …

Forest vegetation management can improve planted seedling survival and growth and is
thus widely used in plantation silviculture. In some jurisdictions, mechanical release using …

Treelines are expected to expand into alpine ecosystems with global warming, but herbivory
may delay this expansion. This study quantifies long-term effects of temporally varying …

Treelines in Alaska are advancing in elevation and latitude because of climate warming,
which is expanding the habitat available for boreal wildlife species, including snowshoe …

Herbivores have the capacity to modify plant community composition and ecosystem
structure and function via browsing. For example, moose and snowshoe hare facilitate …

Herbivores can modify the rate of shrub and treeline advance. Both direct and indirect effects
of herbivory may simultaneously interact to affect the growth rates of plants at this ecotone …
