The paper analyzes Species Abundance Distributions (SADs) in marine plankton communities from surveys and simulations, finding invariant scaling despite environmental and taxonomic variation.

The paper compares implicit and explicit representations of viral dynamics in marine ecosystem models, finding that explicit models better capture virus-induced mortality effects on phytoplankton blooms.

The paper models viral impacts on ocean productivity and biogeochemistry, showing that high viral shunt efficiency enhances productivity across much of the global ocean.

The paper estimates phytoplankton elemental composition and shows how cellular-level changes affect global ocean oxygen consumption and hypoxic zone expansion.

DAR1 is a framework that simplifies complex ocean models for ecological testing and analysis.
