Changes in vegetation structure, including shrub expansion, occur in forest–tundra ecotones in sub‐arctic regions. However, the community‐level processes driving vegetation change are poorly understood. We aimed to evaluate factors mediating the assembly processes for community initiators of vegetation change and determine the ecological processes driving vegetation changes.

正向相互作用通过森林—苔原交错带的灌木扩张促进了景观的同质化

亚北极地区的森林-苔原交错带发生植被结构的变化，包括灌木的扩张。但是，人们对驱动植被变化的社区级过程知之甚少。我们旨在评估介导植被变化社区发起者的组装过程的因素，并确定驱动植被变化的生态过程。
