Variations in Soil Seed Banks in Sedge Peatlands across an Altitude Gradient

Diversity
As a key component of the ecosystem, soil seed banks (SSBs) play a vital role in the evolution and renewal of plant communities. Although the pattern and mechanisms of influence of SSBs along the altitudinal gradient have been reported, most studies have

Relationship Between Community Coverage and Aboveground Biomass in Farming-Withdrawn Grasslands in Loess Hilly-Gully Region

Shuitu baochi yanjiu, 2020
It is of great significance to systematically evaluate the restoration potential of grassland by revealing the relationship between coverage and aboveground biomass of different farming-withdrawn grasslands in loess hilly-gully region.

Intermediate coupling between aboveground and belowground biomass maximises the persistence of grasslands.

PLoS ONE, 2013
Aboveground and belowground biomass compartments of vegetation fulfil different functions and they are coupled by complex interactions. These compartments exchange water, carbon and nutrients and the belowground biomass compartment has the capacity to ...

Synergistic adaptation strategies involving aboveground vegetation and the soil seed bank in the Gurbantunggut Desert

Global Ecology and Conservation
The sustainability of desert ecology depends on synergistic changes in the aboveground and soil seed banks. To explain this process, we undertook fieldwork in the largest fixed-semifixed desert in China, the Gurbantunggut Desert.

Aboveground vegetation and perennial grass seed bank in arid rangelands disturbed by grazing

Rangeland Ecology & Management, 2014
Recruitment by seeds can be an important mechanism for recovery of plant communities following disturbance. Our objective was to assess the density and spatial patterning of perennial grass (highly preferred by herbivores) seeds in litter patches at locations with different aboveground vegetation structure in sites with different grazing history ...

The relative importance of seed competition, resource competition and perturbations on community structure [PDF]

, 2011
While the regional climate is the primary selection pressure for whether a plant strategy can survive, however, competitive interactions strongly affect the relative abundances of plant strategies within communities.

Drought Stress Mediated Changes in Food Crops: Mechanisms and Remediation Strategies

Advanced Science, EarlyView.
This work presents a multi‐scale framework for flavonoid‐mediated drought tolerance in staple food crops, integrating ROS redox regulation, antioxidant defense, rhizosphere microbial interactions, and sustainable agronomic practices. This interdisciplinary model provides core insights to develop climate‐resilient cropping systems and enhance global ...

Rainfall Shapes the Diversity of Soil Nitrogen‐Fixing Microorganisms Worldwide

Advanced Science, EarlyView.
This study reveals the distinctive pattern and mechanism of rainfall driving the global biodiversity and biogeography of soil potential N‐fixing microorganisms, and constructs the theoretical framework. The results guide us on how to maintain ecosystem productivity under future climate changes (e.g., whether a specific region needs more N fertilizers ...

Dynamics of biotic resistance to plant invasions

Biological Reviews, EarlyView.
ABSTRACT Biotic resistance, the reduction in invasion success caused by native communities, plays an important role in the long‐term dynamics of biological invasions. A large body of empirical research on biotic resistance has accumulated since the last comprehensive review on the subject 20 years ago, enabling us to achieve a refined understanding of ...
