The paper develops an eco-physiological model of phytoplankton that incorporates respiration as a key process for nutrient uptake and shows a growth-maintenance tradeoff affecting nutrient-limited growth.

This study compares biodiversity-temperature relationships across space and time using planktonic foraminifera data, finding that space-for-time substitution captures the direction but not the magnitude of biodiversity change.

The paper quantifies how biodiversity affects ecosystem stability using simulations and experiments, finding stability often exceeds expectations due to diversity.
