First Metataxonomic Characterisation of Gut Microbiota of Swordfish (Xiphias gladius). [PDF]

Environ Microbiol Rep
This is the first metataxonomic characterisation of gut microbiota of swordfish using next‐generation sequencing. Findings show significant differences in the alpha diversity among the weight categories and the FAO fishing areas. The phylum Pseudomonadota dominated the swordfish gut microbiota, followed by Fusobacteriota. Photobacterium resulted in the

Almost billfish: convergent longirostry, micro-dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy. [PDF]

J Anat
A fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.

Environmental and human factors shape the trophic ecology of a widespread marine predator. [PDF]

J Anim Ecol
Our study reveals how environmental factors and fishing pressure influence swordfish diet, highlighting trophic shifts under future climate scenarios. We provide a novel framework to strengthen our ability to plan for and manage the redistribution of species under global change ensuring that the energetic needs of predators are met.
