Computing Shrub-Depth Decompositions [PDF]
, 2020 Shrub-depth is a width measure of graphs which, roughly speaking, corresponds to the smallest depth of a tree into which a graph can be encoded. It can be thought of as a low-depth variant of clique-width (or rank-width), similarly as treedepth is a low ...

Tundra shrub expansion may amplify permafrost thaw by advancing snowmelt timing
, 2019 The overall spatial and temporal influence of shrub expansion on permafrost is largely unknown due to uncertainty in estimating the magnitude of many counteracting processes.

Browsing and fire decreases dominance of a resprouting shrub in woody encroached grassland.
Ecology, 2019 North American grasslands have experienced increased relative abundance of shrubs and trees over the last 150 years. Alterations in herbivore composition, abundance and grazing pressure along with changes in fire frequency are drivers that can regulate ...

Shrub encroachment decreases soil inorganic carbon stocks in Mongolian grasslands
Journal of Ecology, 2019 Widespread shrub encroachment in global drylands may increase plant biomass and change soil organic carbon stocks of grassland ecosystems. However, the response of soil inorganic carbon (SIC), which is a major component of dryland carbon pools, to this ...

Structural analysis of a fragmented area in Minas Gerais State, Brazil
Anais da Academia Brasileira de Ciências, 2018 The theory of landscape ecology applied to the methods of spatial analysis helps to understand changes in the structure of forest remnants. In view of this theory, the objective of the present study was to analyze the structure of a fragmented area ...

Tundra plant above-ground biomass and shrub dominance mapped across the North Slope of Alaska
, 2018 Arctic tundra is becoming greener and shrubbier due to recent warming. This is impacting climate feedbacks and wildlife, yet the spatial distribution of plant biomass in tundra ecosystems is uncertain.

Implications of evergreen shrub expansion in the Arctic
Journal of Ecology, 2018 Arctic shrub expansion is occurring across large parts of the tundra biome and its potential ecological repercussions have been widely discussed. But while the term “shrub expansion” often implicitly refers to an increase in tall, deciduous species such ...

Frontiers in Forests and Global Change, 2022 Understanding the responses of shrub growth to climate changes is key to accurately predicting the dynamic changes in the boreal forest ecosystem. A shrub-ring network based on 12 sites was established to explore the response of Pinus pumila growth to ...
