Alnus shrub expansion increases evapotranspiration in the Swiss Alps

Regional Environmental Change, 2018
Shrub encroachment is one of the main consequences of abandonment of montane grassland. Higher surface roughness of shrubs leads to stronger aerodynamic coupling. This should increase evapotranspiration (ET), but lower surface temperatures (due to higher ET and reduced aerodynamic resistance) could counter this effect.

Shrub cover in northern Nunavik: can herbivores limit shrub expansion?

Polar Biology, 2014
Recent climate changes have increased the primary productivity of many Arctic and subarctic regions. Erected shrub has been shown to increase in abundance over the last decades in northern regions in response to warmer climate. At the same time, caribou herds are declining throughout the circumboreal regions.

The evidence for shrub expansion in Northern Alaska and the Pan‐Arctic

Global Change Biology, 2006
AbstractOne expected response to climate warming in the Arctic is an increase in the abundance and extent of shrubs in tundra areas. Repeat photography shows that there has been an increase in shrub cover over the past 50 years in northern Alaska. Using 202 pairs of old and new oblique aerial photographs, we have found that across this region spanning ...
