Initial density affects biomass–density and allometric relationships in self‐thinning populations of Fagopyrum esculentum
TLDR
Interactions among plants and allometry are more important than internal physiological scaling mechanisms in determining the self-thinning trajectory of crowded stands, and interpopulation scaling patterns do not reflect processes within populations, and this conflation lies behind much of the current debate about size–density relationships in plant populations and communities.
Forage nitrogen yield and soil nitrogen in artificial grasslands with varied Medicago seedling proportion
TLDR
It was concluded that pure Medicago stands led to the greatest forage yield, while medium MedChicago stands could lead to the greater symbiotic N fixation and soil N concentration.
Germination Shifts of C3 and C4 Species under Simulated Global Warming Scenario
TLDR
The results indicate that global warming may favour germination of C4 species, at least for the C 4 species studied in this work, and the divergent effects of asymmetric and symmetric warming on plant germination also deserve more attention.
Responses of growing‐season soil respiration to water and nitrogen addition as affected by grazing intensity
1. Most grasslands in the world, including the semi-arid steppe in China, are threat ened by nitrogen deposition, precipitation change and livestock grazing, which greatly affect soil carbon
Evaluating general allometric models: interspecific and intraspecific data tell different stories due to interspecific variation in stem tissue density and leaf size
TLDR
Allometric models may be useful points of departure within some species, growth forms or taxonomic groups as well as related several traits not commonly collected in plant allometric analyses: shoot volume, leaf number, and mean leaf mass.
Phenotypic Plasticity of Early and Late Successional Forbs in Response to Shifts in Resources
TLDR
Patterns of plasticity traits for late successional species exhibited a complex of Master-of-some and Jack- of-all-trades, reflecting their adaptation to resource-poor early successional soil.
The underlying basis for the trade-off between leaf size and leafing intensity
TLDR
The results support the idea that the trade-off between leaf size and volume-based leafing intensity depends on both biomass investment (leaves vs. stems) and stem bulk density (mass vs. volume), whereas the Trade-off Between Leaf size and mass-based Leafing intensity only depends on the biomass investment.
Allometry of corispermum macrocarpum in response to soil nutrient, water, and population density
TLDR
The results showed that biomass allocation was size-dependent and the plasticity of roots, leaf allocation, and reproductive effort was “true” plasticity, and no plasticity was detected in stem allocation in response to soil nutrient variation.
