Aggregated and complementary: symmetric proliferation, overyielding, and mass effects explain fine‐root biomass in soil patches in a diverse temperate deciduous forest landscape
Abstract
Summary Few studies describe root distributions at the species level in diverse forests, although belowground species interactions and traits are often assumed to affect fine‐root biomass ( FRB ). We used molecular barcoding to study how FRB of trees relates to soil characteristics, species identity, root diversity, and root traits, and how these relationships are affected by proximity to ecotones in a temperate forest landscape. We found that soil patch root biomass increased in response to soil resources across all species, and there was little belowground vertical or horizontal spatial segregation among species. Root traits and species relative abundance did not explain significant variation in FRB after correcting for soil fertility. A positive relationship between phylogenetic diversity and FRB indicated significant belowground overyielding attributable to local root diversity. Finally, variation in FRB explained by soil fertility and diversity was reduced near ecotones, but only because of a reduction in biomass in periodically anoxic areas. These results suggest that symmetric responses to soil properties are coupled with complementary species traits and interactions to explain variation in FRB among soil patches. In addition, landscape‐level dispersal among habitats and across ecotones helps explain variation in the strength of these relationships in complex landscapes.
