Contrasting belowground bud banks and their driving factors between alpine and temperate grasslands in China

Global Ecology and Conservation
Despite playing a fundamental role in plant population dynamics, the considerable variability and control of belowground bud banks in grasslands currently remain unknown globally.

Impact of Road Network Development on the Spatiotemporal Soil Erosion in the Three‐River Source Region

Land Degradation &Development, EarlyView.
ABSTRACT As a vital water conservation region in China, the Three River Source Region (TRSR) plays a critical role in safeguarding regional ecological security and ensuring the sustainable utilization of water resources. In this study, the Revised Universal Soil Loss Equation (RUSLE) was employed to quantify soil erosion in the study area across three ...

Water Table Decline Shifts Microbial Necromass From Particulate to Mineral‐Associated Pools in Peatlands

Land Degradation &Development, EarlyView.
ABSTRACT Microbial necromass carbon (MNC) is a major and stable component of soil organic carbon, yet its fraction‐specific accumulation and stabilization mechanisms remain unclear, particularly in peatlands experiencing hydrological change. We investigated MNC distribution along three independent transects spanning a natural gradient of five ...

Bacterial Community Characteristics of Kengyilia thoroldiana Rhizosphere Soil in Different Topographic Habitats of the Yellow River Source Region and Their Response to Vegetation-Soil Factors

Microorganisms
This study aims to uncover the structural and functional characteristics of rhizosphere soil bacterial communities of Kengyilia thoroldiana under five types of topographic habitats in the source region of the Yellow River, and to explore the interaction ...

Overgrazing‐Induced Root Carbohydrate Depletion During Winter Dormancy Drives the Decline of Stipa purpurea Populations in the Tibetan Alpine Steppe

Land Degradation &Development, EarlyView.
ABSTRACT Plant carbon allocation and physiology are influenced by overgrazing during the growth period. However, the response of plant physiological processes to overgrazing during winter dormancy remains unclear. We analyzed root physiological processes of Stipa purpurea in winter dormancy across three plots: over grazing (FG), exclusions of 2 years ...

Plant Trait‐ and Soil‐Mediated Responses of Herbaceous Aboveground Biomass Across Community Types Along a Degradation Gradient in the Desert Steppe

Land Degradation &Development, EarlyView.
ABSTRACT Grassland degradation profoundly alters the structure and function of desert steppe ecosystems. However, the responses of herbaceous aboveground biomass (Herb‐AGB) to degradation across different plant community types and the underlying mechanisms remain poorly understood.

Topographic and Climatic Determinants of Soil Organic Carbon Across Landscapes: A Meta‐Analysis

Land Degradation &Development, EarlyView.
ABSTRACT The soil is the greatest natural store of organic carbon, holding between 1500 to 1550 Pg C of organic carbon at the top 100 cm of the soil globally—roughly twice the carbon pool in the atmosphere. The spatial distribution of this stock is controlled by a complex chain of controls: topographic position regulates the hydrological redistribution,

Temporal Variability of Precipitation and Biomass of Alpine Grasslands on the Northern Tibetan Plateau

Remote Sensing, 2019
The timing regimes of precipitation can exert profound impacts on grassland ecosystems. However, it is still unclear how the peak aboveground biomass (AGBpeak) of alpine grasslands responds to the temporal variability of growing season precipitation (GSP)

Begonia quadricornualata sp. nov. (Begoniaceae) from India

Nordic Journal of Botany, EarlyView.
A new species of Begonia L. (Begoniaceae) belonging to sect. Platycentrum is described from the Papum Pare District of Arunachal Pradesh, India. This new species is distinguished by its dense, long, red to brown hispid hairs on the adaxial leaf surface of female plants, caducous stipules and bracts, and solitary‐flowered female inflorescence ...

Biomass allocation and productivity–richness relationship across four grassland types at the Qinghai Plateau

Ecology and Evolution, 2020
Aboveground biomass (AGB) and belowground biomass (BGB) allocation and productivity–richness relationship are controversial. Here, we assessed AGB and BGB allocation and the productivity–richness relationship at community level across four grassland ...
