Soil seed bank dynamics and vegetation composition in raudhat Altinhat, Saudi Arabia: implications for arid ecosystem restoration

Frontiers in Environmental Science
The soil seed bank (SSB) composition is crucial for ecosystem vitality and restoration. The present study aimed to evaluate the SSB and vegetation composition in Raudhat Altinhat, Saudi Arabia, an arid ecosystem.

Seed bank characteristics in a Pinus densata forest and its relationship with vegetation diversity in Southeast Tibet, China

Ecology and Evolution, 2020
Objective We aimed to understand the basic characteristics of the underground seed bank of Pinus densata forest and its relationship with aboveground vegetation, to provide a theoretical basis for vegetation restoration.

GbLMI1 over-expression improves cotton aboveground vegetative growth

Journal of Integrative Agriculture
Leaves are the main organ for photosynthesis and organic synthesis in cotton. Leaf shape has important effects on photosynthetic efficiency and canopy formation, thereby affecting cotton yield. Previous studies have shown that LMI1 (LATE MERISTEM IDENTITY1) is the main gene regulating leaf shape.

Asynchronous Response of Plant Productivity and Soil Aggregate Nutrients to Grazing Exclusion Duration in Alpine Steppe

Land Degradation &Development, EarlyView.
ABSTRACT Grazing exclusion is a critical restoration measure for degraded alpine steppe ecosystems. However, research remains limited on the key factors influencing soil aggregates that affect plant productivity and the mechanisms influencing nutrient distribution across aggregates of different size fractions during long‐term grazing exclusion.

Intraspecific Variation in Plant Defense Alters Effects of Root Herbivores on Leaf Chemistry and Aboveground Herbivore Damage [PDF]

, 2008
Root herbivores can indirectly affect aboveground herbivores by altering the food quality of the plant. However, it is largely unknown whether plant genotypes differ in their response to root herbivores, leading to variable defensive phenotypes.

Afforestation Partially Offsets Losses of Soil Conservation Services and Carbon Stock From Direct and Indirect Urban Expansion in China

Land Degradation &Development, EarlyView.
ABSTRACT Urban expansion has exerted both direct and indirect impacts on natural land and ecosystem services it supports, driven by increasing population and food demand, yet these underlying pathways remain insufficiently distinguished. Here, we quantified the losses of soil conservation services (water erosion regulation and sandstorm prevention) and

Influence of Aboveground Vegetation on Seed Bank Composition and Distribution in a Great Basin Desert Sagebrush Community [PDF]

, 2012
The quantity, composition, and spatial dispersion of seed banks can greatly affect community dynamics. While seed banks of hot deserts have been studied extensively, little is known about seed banks in cold deserts, in particular the relationship between

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.
