Greenhouse- and field-measured plant-soil feedbacks are not correlated

摘要: Plant-soil feedbacks (PSFs) have become a commonly invoked mechanism of plant coexistence and abundance. Yet, most PSF experiments been performed in greenhouse conditions. To test whether or not greenhouse-measured values are similar magnitude positively correlated with field-measured PSFs, we compared from five different studies that measured both field For 36 species, were larger than values. Similarly, these species produced 269 soil-specific values, for each site there was no positive correlation between greenhouse- While PSFs observed conditions, results provided support at the soil, level exists PSF. Further, appear to overestimate Although studies, strongly suggest needed understand role communities natural settings.
