Shrub encroachment alters the spatial patterns of infiltration [PDF]

Ecohydrology, 2014
AbstractEncroachment of open woodlands by shrubs is a global phenomenon associated with marked changes in ecosystem structure and function. We measured sorptivity and steady‐state infiltration at two supply potentials under shrubs and grasses and in their interspaces where shrubs were encroaching into grassland.

Data from: Shrub encroachment can reverse desertification in semi-arid Mediterranean grasslands [PDF]

, 2013
The worldwide phenomenon of shrub encroachment in grass-dominated dryland ecosystems is commonly associated with desertification. Studies of the purported desertification effects associated with shrub encroachment are often restricted to relatively few ...

Divergent evapotranspiration partition dynamics between shrubs and grasses in a shrub‐encroached steppe ecosystem [PDF]

New Phytologist, 2018
Summary Previous evapotranspiration (ET) partitioning studies have usually neglected competitions and interactions between antagonistic plant functional types. This study investigated whether shrubs and grasses have divergent ET partition dynamics impacted by different water‐use patterns, canopy structures, and physiological properties in a shrub ...

What are the main climate drivers for shrub growth in Northeastern Siberian tundra? [PDF]

, 2011
Deciduous shrubs are expected to rapidly expand in the Arctic during the coming decades due to climate warming. A transition towards more shrub-dominated tundra may have large implications for the regional surface energy balance, permafrost stability and

Dispersal and fire limit Arctic shrub expansion

Nature Communications, 2022
Shrub encroachment trends are widespread yet complex. Here the authors demonstrate that not considering dispersal and fire leads to overestimating shrub expansion in Arctic tundra and therefore its role as carbon sink.

Humped-back shaped response of plant species richness to increasing shrub encroachment in calcareous grasslands [PDF]

, 2015
In the present study, we examined the effect of shrub encroachment in temperate semi-natural grasslands on plant species diversity. We tested the hypothesis that an initial shrub encroachment leads to enhanced habitat heterogeneity and thereby to a ...

Biotic and abiotic changes in ecosystem structure over a shrub-encroachment gradient in the southwestern USA

, 2010
In this study, we investigate changes in ecosystem structure that occur over a gradient of land-degradation in the southwestern USA, where shrubs are encroaching into native grassland.

Canopy-mediated interspecific competition shapes shrub encroachment in alpine meadows: A basis for adaptive management

Ecological Informatics
Shrub encroachment is transforming grassland ecosystems globally, yet the roles of shrub-herbaceous interactions, especially the independent effects of shrub canopy and root systems, in this process remain poorly understood, impeding effective management.

Sexual Reproduction Is Not Responsible for Caragana Shrub Encroachment in Grasslands

Agronomy, 2023
Shrubs tended to increase their abundance as climatic aridity and grazing intensity increased in the Inner Mongolian grassland. Increasing shrub abundance was believed to be due to enhanced reproduction. However, the effects of climatic aridity and grazing on the sexual reproduction of shrubs in grassland remain largely unclear.
