Canadian boreal woodlands and forests cover approximately 3.09× 106 km2, located within
a larger boreal zone characterized by cool summers and long cold winters. Warming since …

Abstract Changes in Arctic vegetation can have important implications for trophic
interactions and ecosystem functioning leading to climate feedbacks. Plot-based vegetation …

To assess ongoing changes in high latitude vegetation productivity we compared
spatiotemporal patterns in remotely sensed vegetation productivity in the tundra and boreal …

The ability of many species to adapt to the shifting environmental conditions associated with
climate change will be a key determinant of their persistence in the coming decades. This is …

Strong evidence for a pan-Arctic expansion of upright shrubs comes from analysis of satellite
imagery, historical photographs, vegetation plots, and growth rings. However, there are still …

The expansion of shrubs into tundra areas is a key terrestrial change underway in the Arctic
in response to elevated temperatures during the twentieth century. Repeat photography …

Observing the environment in the vast regions of Earth through remote sensing platforms
provides the tools to measure ecological dynamics. The Arctic tundra biome, one of the …

We review and present a synthesis of the existing research dealing with changing Arctic
tundra ecosystems, in relation to caribou and reindeer winter ranges. Whereas pan-Arctic …

In order to understand the behaviours and subsistence choices of Palaeolithic hunter–
gatherers, it is essential to understand the behavioural ecology of their prey. Here, we …

Roles of intensive reindeer grazing and several additional land use factors in the reduction
in ground lichens (Cladonia spp.) in pastures grazed by the semi-domesticated reindeer …
