SharkTrack: An accurate, generalisable software for streamlining shark and ray underwater video analysis

open access: yesEcological Informatics
Elasmobranchs (sharks and rays) represent a critical component of marine ecosystems. However, they are experiencing global population declines, making effective monitoring essential for their management.

Phylogeny of the Electric Rays of the Family Narcinidae (Gill, 1862): Systematic Review and Evidence of the Dispersal Routes to America

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 6, June 2026.
ABSTRACT The family Narcinidae has a cosmopolitan distribution; however, its systematic composition and phylogenetic position within Torpediniformes remain poorly understood. This study evaluates the evolutionary and biogeographic history of the family Narcinidae and investigates its distribution patterns using molecular systematics.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

The outcomes of integrating biological interactions into rebuilding plans depend on prey specialization

open access: yesEcological Applications, Volume 36, Issue 4, June 2026.
Abstract Ecosystem dynamics can lead to trade‐offs between reaching harvest targets and protecting vulnerable species across fisheries management decisions. However, in the context of rebuilding overfished populations, considering predator–prey interactions might provide opportunities to minimize or reverse these trade‐offs if overfished prey can ...

Reproductive biology

open access: yes, 2005
Several reproductive specializations are found within the elasmobranchs. All elasmobranchs fertilize internally and produce a relatively small number of large eggs. Elasmobranch fecundity generally ranges from one to two offspring produced a year up to a

Evaluating species at risk in data‐limited fisheries: A productivity–susceptibility analysis for marine aquarium fish

open access: yesEcological Applications, Volume 36, Issue 4, June 2026.
Abstract The marine aquarium trade (MAT) is a significant global industry harvesting millions of wild‐caught, live coral reef fishes for public and private aquaria markets in the United States and Europe annually, while supporting fisher livelihoods in the Indo‐Pacific.

Investigating the Predation Risk of Coastal Dolphins via the Presence of Shark Bite Scars Across Southeast Queensland, Australia

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Shark bite scars were analysed on coastal dolphins in southeast Queensland, Australia to compare the predation risk between species and habitats. Australian humpback dolphins (Sousa sahulensis) exhibited the highest bite rates and individuals found in sheltered waters had higher shark bite scar prevalence than open waters.
