Characterizing and Modeling Arctic Shrub Expansion on the North Slope of Alaska, USA

open access: yes, 2014
Shrub expansion is one of the most recognized components of terrestrial Arctic change and has been documented in studies involving fine-scale experimental manipulations or broad-scale satellite remote sensing.

Potential of C and X Band SAR for Shrub Growth Monitoring in Sub-Arctic Environments

open access: yesRemote Sensing, 2015
The Arctic and sub-Arctic environments have seen a rapid growth of shrub vegetation at the expense of the Arctic tundra in recent decades. In order to develop better tools to assess and understand this phenomenon, the sensitivity of multi-polarized SAR ...

Susceptibility Map for Shrub Expansion on Tundra in ARCN.

open access: yes, 2015
Susceptibility refers to the proportion of the landscape with soils favorable to the formation of high-volume shrub canopies, and ranges from 1.0 (“High”, green) to 0 (“Low”, red).

Land Use and Land Cover Dynamics in Guraferda District, Southwest Ethiopia

open access: yesBlue Nile Journal of Agricultural Research, 2021
In Ethiopia, land use land cover dynamics is one of the major environmental problems. Agricultural expansion has a great role on the changes of land use and land cover in southwest Ethiopian landscapes. This study was therefore carried out to examine the

Water track distribution and effects on carbon dioxide flux in an eastern Siberian upland tundra landscape

open access: yesEnvironmental Research Letters, 2016
Shrub expansion in tundra ecosystems may act as a positive feedback to climate warming, the strength of which depends on its spatial extent. Recent studies have shown that shrub expansion is more likely to occur in areas with high soil moisture and ...

Shrub expansion in SW Greenland under modest regional warming:disentangling effects of human disturbance and grazing

open access: yes, 2013
Shrub expansion has been observed widely in tundra areas across the Arctic. This phenomenon has been partially attributed to increasing temperatures over the past century.

Enhancing understanding of ecological niche and CSR strategies of woody plants in remnant forests: Exploring the impact of surrounding spatiotemporal urban expansion

open access: yesGlobal Ecology and Conservation
Developing a deeper understanding of how plants respond to urbanization in urban remnant forests can enhance biodiversity conservation efforts. This study investigated woody plants in 120 sample plots located in 15 remnant patches and explored the ...
