The paper compares food-web structures in tuna spawning habitats of the Gulf of Mexico and Argo Basin, finding higher ecosystem efficiency in the Argo Basin due to differences in zooplankton herbivory and nutrient cycling.

The paper quantifies carbon export and sinking particle characteristics in the eastern Indian Ocean, finding net remineralization in the deep euphotic zone and similar patterns to the Gulf of Mexico.

The paper investigates grazing pathways in tropical oligotrophic waters by analyzing copepod and microzooplankton diets, finding that microzooplankton remove most daily production while copepods show moderate selection for picoplankton.

The paper examines protist export dynamics in subtropical and subantarctic waters, finding taxon-specific patterns in their loss during particle sinking and remineralisation.

The paper measures carbon fixation rates and taxonomic composition of small phytoplankton in different oceanic regions, suggesting phago-mixotrophy may help alleviate iron limitation in certain populations.
