The Critical Role of Coefficients: Updating Allometric Normalisation Constants for Modern Ecology and Modelling

Ecology Letters, Volume 29, Issue 2, February 2026.
Allometry is central to a wide range of ecological research including dynamic food web modelling. Here we updated the often neglected allometric coefficients for metabolism and production, deriving new genus and metabolic group levels estimates with phylogenetic hierarchical modelling providing robust inference.

The muscle-powered bite of allosaurus (dinosauria; theropoda): an interpretation of cranio-dental morphology [PDF]

, 2003
11 pages, 7 figures.[EN] The skull morphology of Allosaurus has been the subject of functional interpretations which imply a predatory behaviour radically different from that recorded in any predatory land vertebrate.

Morphology and paleoecology of a hybodontiform with serrated teeth, Priohybodus arambourgi, from the Late Jurassic of northeastern Brazil

The Anatomical Record, Volume 309, Issue 1, Page 5-32, January 2026.
Abstract Hybodontiformes was a diverse, successful, and important group of shark‐like chondrichthyans known from a variety of ecosystems. Some representatives of the order had a wide palaeogeographic distribution, as is the case with Priohybodus arambourgi. With a multicuspidate crown, P. arambourgi was the first hybodontiform to develop fully serrated

Only One Percent of Important Shark and Ray Areas in the Western Indian Ocean Are Fully Protected From Fishing Pressure

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Delineation of Important Shark and Ray Areas (ISRAs) In the Western Indian Ocean was enhanced by the verification and incorporation of unpublished records. Even with this expanded dataset, ~99% of ISRA coverage fell outside of fully protected, no‐take MPAs.

White Shark or Shortfin Mako? Lamnid sharks identification in an overlapping area of the Equatorial Southwestern Atlantic

Ocean and Coastal Research
Despite their worldwide distribution, the occurrence of Lamnidae species in tropical zones remain poorly understood. In the Equatorial Southwestern Atlantic, the Shortfin Mako, Isurus oxyrinchus, has been captured in commercial fisheries, whereas the ...

A Comparison of DNA Metabarcoding Cloacal Swabs and Stomach Contents for Shark Diet Reconstruction

Environmental DNA, Volume 8, Issue 1, January–February 2026.
Our results indicate that the less invasive, non‐lethal method of DNA metabarcoding cloacal swabs provided higher taxonomic resolution than more common methods for studying shark trophic ecology (i.e., morphological stomach contents identification and trophic biomarkers) with no statistical difference in overall diet description between cloacal swabs ...

Intraguild predation in sympatric seals and the effect on a declining population

Journal of Animal Ecology, Volume 94, Issue 12, Page 2572-2583, December 2025.
This study examined the prevalence, spatial extent, and temporal trends of grey seal intraguild predation (IGP). We demonstrated the utility of integrating disparate datasets to address conservation challenges and highlighted how IGP, while seemingly rare, can hold sympatric species in a predator‐pit and in small populations may contribute to declines.
