BACKGROUND Fire has shaped the diversity of life on Earth for millions of years. Variation
in fire regimes continues to be a source of biodiversity across the globe, and many plants …

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 …

The majority of area burned by wildfire are located in Siberia. Mainly low-intensity surface
fires occur in larch forests, whereas in evergreen forests both surface and crown fires are …

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 …

Anthropogenic climate change may result in novel disturbances to Arctic tundra ecosystems.
Understanding the natural variability of tundra‐fire regimes and their linkages to climate is …

Background Earth system models describe the physical, chemical and biological processes
that govern our global climate. While it is difficult to single out one component as being more …

Climatic change is anticipated to alter disturbance regimes for many ecosystems. Among the
most important effects are changes in the frequency, size, and intensity of wildfires. Serotiny …

Recent large and frequent fires above the Alaskan arctic circle have forced a reassessment
of the ecological and climatological importance of fire in arctic tundra ecosystems. Here we …

Time-varying fire-climate relationships may represent an important component of fire-regime
variability, relevant for understanding the controls of fire and projecting fire activity under …

Shrubs are expanding in Arctic ecosystems, and herbivores may be influencing this
expansion by reducing the growth of preferred forage species. We synthesized new and …
