The paper identifies 25 novel phyla in the eukaryotic tree of life through global environmental DNA surveys and proposes formal names for 150 species.

The paper shows that increasing soil microbiome predator diversity boosts Cannabis sativa biomass more than nitrogen addition, by altering bacterial communities and nutrient cycling functions.

This study shows that top predators in soil food webs increase carbon cycling efficiency by altering microbial communities and reducing heterotrophic respiration.

The paper analyzes global distribution patterns of soil fungal nematode antagonists and identifies environmental drivers influencing their abundance.

This study uses quantitative stable isotope probing (qSIP) to measure in situ growth rates of soil protists across a moisture gradient, revealing significant differences in growth rates and taxa abundance.

The paper investigates patchy potato cyst nematode distribution in fields and identifies microbial communities responsible for local disease suppressiveness.
