Summary
This review revisits the root economics space concept — a framework organising fine-root functional traits along axes reflecting resource acquisition versus conservation strategies — assessing how the framework has been applied, extended and refined since its introduction. The authors, drawn from multiple European institutions with expertise in root ecology, likely synthesise empirical evidence and identify where the original RES model requires nuance, particularly regarding mycorrhizal interactions, root order distinctions and environmental context. The paper advances understanding of below-ground plant functioning with implications for modelling carbon and nutrient cycling in diverse ecosystems.
UK applicability
Although the paper is likely global in scope, the findings are broadly applicable to UK managed and semi-natural systems, informing understanding of root-mediated nutrient cycling in arable, grassland and woodland contexts relevant to soil health policy and sustainable land management.
Key measures
Fine-root traits (e.g. specific root length, root diameter, root tissue density, mycorrhizal colonisation, root lifespan, nutrient uptake rates); root economics space axes
Outcomes reported
The paper examines the applications, extensions and nuances of the root economics space (RES) framework, likely reviewing how fine-root functional traits relate to resource acquisition, conservation and soil interactions across plant species and ecosystems.
