The Role of Functional Traits in Structuring Fish Assemblages Across the Four Macaronesia Archipelagos

open access: yesJournal of Biogeography, Volume 53, Issue 2, February 2026.
ABSTRACT Aim To investigate how functional traits shape the composition and functional structure of coastal fish assemblages across the four North‐East Atlantic archipelagos, providing insights into the ecological drivers of species distributions and trait patterns in oceanic island systems. Location Four North‐East Atlantic oceanic archipelagos within

Niche Differentiation of Aerobic and Anaerobic Ammonia Oxidizers in a High Latitude Deep Oxygen Minimum Zone

open access: yesFrontiers in Microbiology, 2019
To elucidate the potential for nitrification and denitrification processes in a high latitude deep oxygen minimum zone (OMZ) we determined the abundance and community composition of the main microbial players in the aerobic and anaerobic (anammox ...

Diversity and Ecological Potentials of Marine Viruses Inhabiting Continental Shelf Seas

open access: yesAdvanced Science, Volume 13, Issue 1, 5 January 2026.
To the best of the knowledge, this study provides the largest viral genome dataset from a continental shelf sea. It reveals that over half of vOTUs are novel, highlighting the remarkable viral novelty in the eastern continental shelf seas of China (ECSSC).

The Bathypelagic Biome of the Atlantic Ocean: Character and Ecological Discreteness of the Fish Fauna [PDF]

open access: yes, 2012
Recent global synthetic analyses have revealed that marine taxonomic inventories are far from complete, nowhere more so than in the deep-pelagic ocean. At over a billion km3, it is the largest biome on Earth, yet only a tiny fraction of the biogeographic

Deep-water observation of scalloped hammerhead Sphyrna lewini in the western Indian Ocean off Tanzania [PDF]

open access: yes, 2015
A scalloped hammerhead Sphyrna lewini was observed opportunistically from a remotely operated vehicle 1 m off the seabed at 1042 m depth, during hydrocarbon exploration activities in the Ruvuma Basin off Tanzania.

Evaluating Prey Availability for the Rice's Whale (Balaenoptera ricei) Based on Environmental DNA

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
To characterize the prey community of the critically endangered Rice's whale, we employed environmental DNA (eDNA) metabarcoding in its core habitat. Our multi‐marker approach detected significantly greater fish biodiversity than concurrent trawl surveys and revealed a higher prevalence of key prey taxa.

Oceanic adults, coastal juveniles: tracking the habitat use of whale sharks off the Pacific coast of Mexico [PDF]

open access: yes, 2017
Eight whale sharks tagged with pop-up satellite archival tags off the Gulf of California, Mexico, were tracked for periods of 14–134 days. Five of these sharks were adults, with four females visually assessed to be pregnant.

Environmental Gradients and Ecological Processes Are Main Drivers of Eukaryotic Diversity in the Eastern Red Sea

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
Across 266 water column samples, COI eDNA metabarcoding detected 4298 eukaryotic MOTUs spanning 40 phyla in the Eastern Red Sea. Community composition varied strongly across depth and regions, revealing hidden biodiversity patterns and providing a baseline for conservation‐oriented monitoring in a future‐ocean analogue.
