The paper assesses ammonium retention by Amberlite IRC-748 resin, finding it removes metal ions but co-adsorbs NH4+ with concentration-dependent losses, affecting high-precision N analysis.

The paper examines how multitrophic species interaction networks influence ecosystem multifunctionality and finds that network structure, including niche overlap and linkage density, significantly affects ecosystem function.

The paper examines how tree diversity affects microbial investment in nutrient-acquiring enzymes in soil, finding increased investment in nitrogen and phosphorus acquisition with higher tree species richness.
