To increase the yield and quality of aquaculture feed, the effects of N and P concentrations on biomass productivity and cell composition were examined in the marine diatom Skeletonema costatum. Batch-cultured microalgae in Walne’s medium with 3.5 ± 0.5 mmol L-1 N-NO3- and 0.30 ± 0.05 mmol L-1 P-PO43- …

There is consensus that plant species richness enhances plant productivity within natural grasslands, but the underlying drivers remain debated. Recently, differential accumulation of soil‐borne fungal pathogens across the plant diversity gradient has been proposed as a cause of this pattern. However, …
