Tundra vegetation productivity and composition are responding rapidly to climatic changes
in the Arctic. These changes can, in turn, mitigate or amplify permafrost thaw. In this Review …

Vegetation composition shifts, and in particular, shrub expansion across the Arctic tundra
are some of the most important and widely observed responses of high-latitude ecosystems …

Snow is an important driver of ecosystem processes in cold biomes. Snow accumulation
determines ground temperature, light conditions, and moisture availability during winter. It …

Extreme droughts, heat waves, frosts, precipitation, wind storms and other climate extremes
may impact the structure, composition and functioning of terrestrial ecosystems, and thus …

Recent research using repeat photography, long-term ecological monitoring and
dendrochronology has documented shrub expansion in arctic, high-latitude and alpine …

Terrestrial ecosystems have encountered substantial warming over the past century, with
temperatures increasing about twice as rapidly over land as over the oceans. Here, we …

There has been a recent surge of interest in remote sensing and its use in ecology and
conservation but this is the first book to focus explicitly on the NDVI (Normalised Difference …

Global temperature is increasing, especially over northern lands (> 50° N), owing to positive
feedbacks. As this increase is most pronounced in winter, temperature seasonality (ST) …

Several recent climate impact assessments on polar regions have been undertaken,
including the synthesis report on Snow, Water, Ice and Permafrost in the Arctic (AMAP …

Under climate change, not only the magnitude, but also the frequency of extreme weather
events is predicted to increase. Such repeated climate stress events may cause fundamental …
