Dynamic trajectories of growth and nitrogen capture by competing plants
TL;DR: Biomass and N capture trajectories demonstrated that competitive outcomes depend crucially on when and how 'competition' is measured, which potentially compromises the interpretation of conventional competition experiments.

Root-shoot growth responses during interspecific competition quantified using allometric modelling.
TL;DR: Given reasonable assumptions, allometric modelling can analyse competitive interactions in any species mixture, and overcomes a long-standing problem in studies of competition.

A New Hammer to Crack an Old Nut: Interspecific Competitive Resource Capture by Plants Is Regulated by Nutrient Supply, Not Climate
TL;DR: Using isotope pool-dilution, the interactive effects of soil resource limitation and climatic severity between two common grassland species are examined and the results do not entirely support either of the main current theories relating the role of competition to environmental conditions.
Directly quantifying multiple interacting influences on plant competition
TL;DR: The results support the view that measuring resource capture or biomass production tells you different things about how competitors interact with one another and their environment, and that biomass is a longer-term integrative proxy for the outcomes of multiple separate interactions occurring between plants.

Strain Identity of the Ectomycorrhizal Fungus Laccaria bicolor Is More Important than Richness in Regulating Plant and Fungal Performance under Nutrient Rich Conditions
Christina Hazard,Laura M. Kruitbos,Hazel Davidson,Fatou Tall Mbow,Andy F. S. Taylor,Andy F. S. Taylor,David W. Johnson +6 more
TL;DR: The hypothesis that increasing the chemical complexity and forms of soil nutrients would enhance the effects of intraspecific ECM diversity on host plant and fungal productivity is tested and suggests soil nutrient composition does not interact strongly with ECM intraspescific richness.
