Sandblasting promotes shrub encroachment in arid grasslands

New Phytologist, 2023
Summary Shrub encroachment is a common ecological state transition in global drylands and has myriad adverse effects on grasslands and the services they provide. This physiognomic shift is often ascribed to changes in climate (e.g. precipitation) and disturbance regimes (e.g. grazing and fire), but this remains debated. Aeolian processes are known to

Effects of vegetation on bacterial communities, carbon and nitrogen in dryland soil surfaces: implications for shrub encroachment in the southwest Kalahari [PDF]

, 2020
Shrub encroachment is occurring in many of the world's drylands, but its impacts on ecosystem structure and function are still poorly understood. In particular, it remains unclear how shrub encroachment affects dryland soil surfaces, including biological

Effects of shrub encroachment on soil organic carbon in global grasslands. [PDF]

Sci Rep, 2016
AbstractThis study aimed to evaluate the effect of shrub encroachment on soil organic carbon (SOC) content at broad scales and its controls. We conducted a meta-analysis using paired control data of shrub-encroached grassland (SEG) vs. non-SEG collected from 142 studies worldwide.

Effects of shrub encroachment on soil aggregates and organic carbon vary in different grasslands in Inner Mongolia, China

Ecosphere, 2021
Widespread shrub encroachment in grasslands can lead to changes in soil aggregates and soil organic carbon (SOC), especially in deep soils. Soil aggregates physicochemically protect SOC and thus affect soil carbon sequestration.

Effect of Shrub Encroachment on Alpine Grass Soil Microbial Community Assembly

Frontiers in Soil Science, 2022
Shrub encroachment is a common phenomenon in grasslands all over the world. However, little is known about the consequences of shrub encroachment on soil microbial community structure in different layers. We investigated the effects of three common shrub

Effect of shrub encroachment on leaf nutrient resorption in temperate wetlands in the Sanjiang Plain of Northeast China

Ecological Processes, 2022
Background Nutrient resorption is an important plant nutrient conservation strategy in wetlands. However, how shrub encroachment alters plant nutrient resorption processes is unclear in temperate wetlands.

Modelling the shrub encroachment in a grassland with a Cellular Automata Model [PDF]

Proceedings of the International Association of Hydrological Sciences, 2014
Arid and semi-arid grasslands of southwestern North America have changed dramatically over the last 150 years as a result of shrub encroachment, i.e. the increase in density, cover and biomass of indigenous shrubby plants in grasslands.

Is shrub removal an appropriate management strategy in shrub-encroached woodlands? [PDF]

WIT Transactions on Ecology and The Environment, 2011
Encroachment of shrubs into open woodland is a global phenomenon affecting drylands worldwide. Encroachment generally reduces pastoral productivity by reducing grass cover for livestock. Consequently, a range of mechanical methods such as ploughing have been used in an attempt to remove encroaching shrubs.
