Tree Resource Economics Control Soil Food Web Multifunctionality
A study published in Nature reveals that the resource economics of dominant tree species significantly control soil food web multifunctionality across European forests. Researchers applied a food web energetics approach to demonstrate that tree communities dominated by resource-acquisitive species promote faster rates of multiple soil trophic functions compared to those dominated by resource-conservative species. This effect is primarily driven by higher-quality litter and warmer forest microclimates, which increase the metabolic activity of soil organisms. The study found that tree species composition explains a large portion of variation in soil food web multifunctionality, comparable to biogeographic differences. Conversely, mixtures of three tree species showed weakly negative effects relative to single-species stands, largely due to shifts in energy channeling from living fine roots to litter and a cooling effect on the microclimate. These findings highlight the critical role of plant functional traits in driving belowground ecosystem functioning and suggest that climate-driven shifts in tree community composition could substantially alter forest soil processes, offering new insights for forest management and ecological conservation strategies.
