Effects of phylogenetic isolation aboveground (PIA) and
belowground (PIB) on litter decomposition, soil biota and carbon isotope
Loss of mass, C and N . PIA increased C loss after 8 months,
decreased C loss after 14 months and decreased mass loss after 14 months
(Fig. 2). PIB decreased litter C loss after 8 months (Fig. 2). PIA and
PIB did not affect mass loss or N loss after 8 months.
Abundances of decomposers . PIA decreased microbial biomass after
14 months (Fig. 2). PIB decreased microbial biomass and Collembola
abundance after 8 and 14 months, and increased Acari abundance after 8
months (Fig. 2). PIA or PIB did not affect fungal abundance or diversity
after 8 months (Supplementary Figure S1).
Carbon isotope . PIA decreased litter13C/12C after 8 months, while PIB
decreased litter 13C/12C after 14
months of decomposition (Fig. 3).
