Invariant scaling of the Species Abundance Distribution in observed and simulated marine plankton communities

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

Implicit representation of viruses fails to capture impacts of virus-induced mortality in global marine ecosystem models

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.

Viral impacts on plankton standing stocks, primary productivity, and biogeochemistry in a model ocean

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

Cellular-level control on global ocean deoxygenation driven by phytoplankton ecophysiology

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