Hopping Hotspots Shaped the Global Biogeography and Diversification of Orectolobiform Sharks

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim In marine biogeography, many clades exhibit their greatest species richness in the Central Indo‐Pacific region, which includes the Indo‐Australian Archipelago. However, there is no consensus that this region was the ancestral cradle of clade's species richness.

Dental crown morphological variation and heterodonty in carcharhiniform sharks

The Anatomical Record
Abstract Elasmobranch teeth are highly mineralized structures that constitute the majority of the fossil record for this group. Despite their taxonomic and evolutionary significance, detailed descriptions of dental morphology remain scarce.

Measuring juvenile habitat quality for fishes and invertebrates

Biological Reviews, Volume 100, Issue 6, Page 2346-2395, December 2025.
ABSTRACT Identifying the role of marine and estuarine habitats in supporting fish and invertebrate populations during vulnerable juvenile life stages is essential to achieve effective conservation and fisheries management. There remains general agreement that: (i) the quality of juvenile habitat is best measured as the contribution of juveniles to ...

Rapid DNA/eDNA‐Based ID Tools for Improved Chondrichthyan Monitoring and Management

Molecular Ecology Resources, Volume 25, Issue 8, November 2025.
ABSTRACT Rapid DNA/eDNA‐based ID tools, which detect specific genetic patterns without requiring sequencing, are essential for biodiversity and wildlife trade monitoring, particularly for species of conservation concern. However, the practical application of these methods remains limited by the availability of standardised protocols, accessibility of ...

The Motion Picture: Leveraging Movement to Enhance AI Object Detection in Ecology

Ecology and Evolution, Volume 15, Issue 8, August 2025.
As AI methods become increasingly popular to automatically analyse ecology data, we investigate using movement information as a means to improve traditional object detection approaches (which are limited to static image information only) on over 35,000 annotated images from 1480 terrestrial, marine and freshwater locations, the most extensive ...
