Remote sensing characterisation of the forest-tundra ecotone
The transition zone between the boreal forest and Arctic tundra, the Forest-tundra ecotone (FTE), is an area of high ecological and climatological significance. Satellite remote sensing has the potential to enable accurate circumarctic mapping and characterisation of both latitudinal and …

Fine-Scale Mechanisms Influencing Germination Success, Seedling Growth and Survival in an Alpine Forest-Tundra Ecotone
… and seedling survival in the alpine treeline ecotone? Four specific investigations were used to answer these questions, each one addressing a key aspect of seed production, germination, and seedling growth: (1) Seed production, dispersal, and predation were quantified across the treeline …

Holocene variations in summer temperature and effective moisture: Understanding the causes of vegetational dynamics in Alaska
… on soil carbon pools. However, responses of the forest—tundra ecotone to the modern warming trend are spatially heterogeneous because controls other than temperature limit tree growth and seedling establishment near tree line. Paleo-investigations can address the sensitivity of the forest—tundra …

Spruce bark beetle disturbance in the forest-tundra ecotones of southwest Yukon: impacts and predisposing factors
As climate warms, phytophagous forest insects are expected to advance into previously unoccupied regions and/or experience population eruptions within their extant ranges. Already stressed by abiotic factors, arctic and alpine treeline environments will therefore become increasingly vulnerable to …
