Previous surveys of small mammals in Alaska (Cook and MacDonald 2004, 2006) identified a contact zone between 2 closely related species of the cinereus complex of shrews (Van Zyll de Jong 1991; Demboski and Cook 2003) along the forest-tundra ecotone in northern Alaska.

The Koryaks are native to northeastern Siberia, on the northern part of the Kamchatka Peninsula and on the adjoining mainland, from the Taigonos Peninsula to the Bering Sea, areas that are characterised by sub-Arctic forest-tundra and tundra.

Russia's frigid heart: a near-permanently frozen region of rivers, mountains, tundra and forest enclosed by the Ural Mountains in the west and the Pacific and Arctic oceans in the east, Siberia is a place of extremes.

Moose appeared in the forest-tundra zones in the 1950s, occupied the Ponoy River area in the 1960-1970s, and population growth occurred to the north of the forest zone along the tributaries and rivers flowing into the Barents Sea.

Most well-drained sites in the northern Quebec forest-tundra are colonized by lichen-heath communities and scattered black spruce (Picea mariana (Mill.) BSP.), woodlands, and krummholz (stunted spruce).

Reconstruction of millennial forest dynamics from tree remains in a subarctic tree line peatland

The pollen and macrofossil assemblages of zone F4 are indicative of a shrub-tundra or forest-tundra. The strongest evidence for vegetation response to a severe climatic cooling comes from the abundance of arctic/ alpine or boreal species in the macrofossil record, such as Vaccinium uliginosum, Salix herbacea, and Dryas integrifolia.

Impact of the Younger Dryas cooling event upon lowland vegetation of Maritime Canada

We established eight transects (50-100 m in length) along an elevation gradient in three tree-line zones (forest, forest-tundra, and alpine-tundra) and recorded all species and cover of vegetation in contiguous 1 x 1 m quadrats.

Complex changes in plant communities across a subarctic alpine tree line in Labrador, Canada

To test both hypotheses, we analyzed macrofossil remains across a long transect from forest-tundra to tundra, to determine whether or not the eastern Canadian forest limit shifted in unison with climate change during the late Holocene.
