Comparative food-web analysis of bluefin tuna spawning habitats in the eastern Indian Ocean and Gulf of Mexico

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.

Analysis of environmental data during a lagrangian experiment: The influence of vertical movements.

The paper analyzes environmental data from Lagrangian ocean experiments, showing that density surfaces better capture variability than depth, confirming the Lagrangian nature of the experiments.

Optimal Maternal Feeding Isotopic Niche: influence of breeder trophic behaviour on larval growth and survival in bluefin tuna species

This study examines how maternal trophic behavior influences larval growth and survival in bluefin tunas by analyzing isotopic signatures and growth rates across multiple populations.

Phytoplankton community composition in the oligotrophic Argo Basin of the eastern Indian Ocean

The paper describes phytoplankton community composition in the oligotrophic Argo Basin during austral summer 2022, highlighting taxonomic and functional diversity across different depth layers.

Sinking particle export within and beneath the euphotic zone in the eastern Indian Ocean

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.

Trophic specialization enhances growth performance in larvae of southern bluefin, albacore, and skipjack tunas from the eastern Indian Ocean

This study examines how trophic specialization affects larval growth in three tuna species, finding that optimal growth correlates with narrower trophic niches and lower trophic positions.

Exploring the roles of trophic mode and microbial prey size in grazing pathways of tropical oligotrophic waters of the eastern Indian Ocean

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.

Revisiting daily growth and survival insights of Southern bluefin tuna (Thunnus maccoyii) larvae in the eastern Indian Ocean

This study examines growth and survival of Southern bluefin tuna larvae in the eastern Indian Ocean, finding faster growth rates and survival linked to temperature and prey changes.

Primary productivity and N2-fixation in the eastern Indian Ocean: bottom-up support for an ecologically and economically important ecosystem

The paper quantifies primary productivity and nitrogen fixation in the eastern Indian Ocean, showing nitrogen recycling and N2 fixation support ecosystem productivity.

Acidic vacuole-containing organisms are a majority of the eukaryotic microbial community in oligotrophic Argo Basin waters (eastern Indian Ocean)

The paper identifies mixotrophs as a dominant component of the eukaryotic microbial community in oligotrophic Argo Basin waters, with high proportions of acid vacuole-containing microbes.

Phytoplankton community structure and photophysiological strategies in the oligotrophic Indian Ocean spawning ground of Southern Bluefin Tuna

This study identifies Prochlorococcus as dominant in the oligotrophic Argo Basin, revealing photophysiological strategies that enable survival under nitrate limitation and Fe stress, and shows how mesoscale eddies episodically alter phytoplankton communities.

Microbial food web dynamics in tropical waters of the bluefin tuna spawning region off northwestern Australia

The paper quantifies microbial carbon flows in the spawning region of Southern Bluefin Tuna off NW Australia, showing Prochlorococcus dominates production and grazing in the upper euphotic zone.
