Summary

This global meta-analysis synthesises observational data on grassland biomass allocation across multiple continents to elucidate how grazing management intensity and environmental drivers (climate, altitude) shape shoot–root partitioning. The work appears to clarify resource allocation strategies in pastoral systems, with potential implications for understanding forage productivity and soil carbon storage dynamics under contrasting management practices. The analysis likely demonstrates how environmental context and grazing regimes interact to influence above- and below-ground biomass investment strategies.

Regional applicability

Findings from this global meta-analysis may have relevance to UK grassland and pastoral systems, particularly upland grazing contexts where altitude and climate variation are significant. However, direct applicability would depend on whether UK pastoral systems and their climate-altitude gradients were adequately represented in the underlying datasets; transferability should be evaluated against local soil types, vegetation composition, and grazing management intensity.

Key measures

Shoot-to-root biomass ratio, above-ground and below-ground biomass allocation, climate variables (temperature, precipitation), altitude, grazing intensity/management practices

Outcomes reported

The study examined grassland biomass allocation (shoot-to-root partitioning) across continents and grazing practices, measuring how climate, altitude, and grazing intensity influence resource allocation strategies. Outcomes likely included quantification of above- and below-ground biomass fractions under different pastoral management regimes and environmental conditions.
