Repatterning of mammalian backbone regionalization in cetaceans
Cetacean reinvasion of the aquatic realm is an iconic ecological transition that led to drastic modifications of the mammalian body plan, especially in the axial skeleton. Relative to the vertebral column of other mammals that is subdivided into numerous

ABSTRACT Major threats to marine species and ecosystems include overfishing, invasive species, pollution and climate change. The changing climate not only imposes direct threats through the impacts of severe marine heatwaves, cyclones and ocean acidification but also complicates fisheries and invasive species management by driving species range shifts.

ABSTRACT The AquaEcOmics meeting brought together 280 scientists applying omics tools to aquatic research in March 2025 (Evian‐les‐Bains, France). We synthesised here the main outcomes from the 167 presentations which were given. A similar number of presentations were about micro‐ and macroorganisms.

ABSTRACT Humpback whale (Megaptera novaeangliae) super‐groups, comprising 20+, tightly aggregated, feeding individuals, form during the austral summer in the southern Benguela ecosystem off the west coast of South Africa. This phenomenon, observed since 2011, is thought to be linked to increased productivity from positive chlorophyll‐a anomalies ...

Metagenomic Insights Into the Role of Gut Microbes in the Defensive Ink “Tsunabi” of Physeteroid Whales [PDF]
Whales of the superfamily Physeteroidea exhibit a unique visual defense mechanism involving the release of dark reddish‐brown feces (locally called “tsunabi‐ink” in Japan) into the water. This study proposes that tsunabi‐ink is a metabolic byproduct of shifts in the gut microbial community, influenced by the host's digestive physiology and foraging ...

ABSTRACT We applied stable carbon and nitrogen isotopes to investigate the trophic ecology of four large pelagic predators from the Fernando de Noronha Archipelago (FNA), northeastern Brazil: spinner dolphin (Stenella longirostris), yellowfin tuna (Thunnus albacares), wahoo (Acanthocybium solandri), and great barracuda (Sphyraena barracuda).

ABSTRACT Assessing the genetic diversity of a population is critical to evaluate its resilience in the face of anthropogenic impacts. This study aimed to assess the genetic diversity and structure of the spinner dolphins (Stenella longirostris) that inhabit the Santos Basin (SB), south and southeast Brazil.

Semi‐Automated Detection of Right Whales (Eubalaena spp.) in Very High‐Resolution Satellite Imagery
ABSTRACT Space‐based detection of whales is proliferating because it shows promise as a monitoring tool, yet tests of its application across taxa and environments are rare. The objective of this study was to develop an end‐to‐end, semi‐automated procedure for detecting two right whale species (Eubalaena glacialis and E. australis) in satellite imagery.
