Plant functional traits affect invertebrate predator diversity via bottom-up effects in a deadwood-based food web

Bottom-up effects play a critical role in shaping community structure and trophic interactions within detritus-based food webs. Coarse deadwood supports high biodiversity and contributes to detrital food webs during its decomposition process. Previous experiments have shown that wood functional traits have significant impacts on detritivore communities. However, this effect has rarely been tested on higher trophic levels, even less so relationships between plant functional traits and predators via detritivores.
In this study, we investigated the effects of wood functional traits, synthesized into the wood economics spectrum (WES), on the abundance and diversity of detritivores and predators throughout the decomposition process of 22 different tree species in eastern China. We hypothesized that the WES has strong direct effects on detritivores and indirect effects on predators as mediated by detritivores.
We found that the WES affected detritivore abundance ..., , # Data from: Plant functional traits affect invertebrate predator diversity via bottom-up effects in a deadwood-based food web

`Ci_et_al_dataset.xlsx` includes the measured data of wood economic spectrums (PC1) based on the wood carbon, nitrogen, and phosphorus concentration, lignin, cellulose concentration, and wood density, and detritivore and predator abundance and richness.
