A giant plagiosaurid temnospondyl from Bjørnøya (Svalbard, Norway) and the origin of the plagiosaurid body plan

Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract An articulated temnospondyl skeleton from Middle Triassic deposits of Bjørnøya (Bear Island) in the western Barents Sea is described as a new plagiosaurid genus and species, Arctobatrachus urdensis. With a body length well exceeding 2 m, it represents by far the largest known member of the Plagiosauridae.

Control of the development of the pulmonary surfactant system in the saltwater crocodile,Crocodylus porosus [PDF]

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2002
Pulmonary surfactant is a mixture of lipids and proteins that controls the surface tension of the fluid lining the inner lung. Its composition is conserved among the vertebrates. Here we hypothesize that the in ovo administration of glucocorticoids and thyroid hormones during late incubation will accelerate surfactant development in the saltwater ...

Injuries in deep time: interpreting competitive behaviours in extinct reptiles via palaeopathology

Biological Reviews, Volume 101, Issue 3, Page 1073-1090, June 2026.
ABSTRACT For over a century, palaeopathology has been used as a tool for understanding evolution, disease in past communities and populations, and to interpret behaviour of extinct taxa. Physical traumas in particular have frequently been the justification for interpretations about aggressive and even competitive behaviours in extinct taxa.

eDNA signals improve local predictions of fish abundances in Mediterranean coastal ecosystems

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
This study demonstrates that integrating eDNA metabarcoding data into species distribution models can improve fish abundance predictions, especially for site‐attached and reef‐associated species. This approach provides a scalable and cost‐effective tool for monitoring, impact assessment, spatial planning and adaptive management of marine resources ...

Tracking Fin‐Prints on Reef Flats: A Genus‐Specific eDNA Metabarcoding Assay for Epaulette Sharks (Hemiscyllium spp.) With Field Validation in Raja Ampat

Environmental DNA, Volume 8, Issue 3, May–June 2026.
This study developed and validated the first genus‐specific eDNA assay for epaulette sharks (Hemiscyllium spp.), targeting the NADH4 gene. Field application in Raja Ampat detected H. freycineti at six of seven locations, including one location (Dayan) where daytime visual surveys failed, demonstrating this tool's value for monitoring protected species.

High genetic diversity and demographic history of captive Siamese and Saltwater crocodiles suggest the first step toward the establishment of a breeding and reintroduction program in Thailand.

PLoS ONE, 2017
The Siamese crocodile (Crocodylus siamensis) and Saltwater crocodile (C. porosus) are two of the most endangered animals in Thailand. Their numbers have been reduced severely by hunting and habitat fragmentation.

Using biotelemetry to assess drone effects on whale sharks

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract The use of unoccupied aerial vehicles or drones for wildlife research has proliferated in recent years and they have proven to be a valuable tool for collecting data for population surveys, morphometric and body condition measurements, and for observing behavior.

Genome‐wide identification and solute selectivity of aquaporins in the sharpnose sevengill shark, Heptranchias perlo

Physiological Reports, Volume 14, Issue 8, April 2026.
Abstract The aquaporin genes (aqps) are widely distributed among vertebrates. In cartilaginous fish, aqp3 and aqp10 are duplicated, whereas many species have lost aqp8. While the solute permeability of aquaglyceroporins and Aqp8 exhibits significant diversity, systematic evaluations of their activity within species are limited.

Advancing Environmental DNA Applications in Southeast Asia Through Networking, Adaptable Standard Development, and Capacity Building

Environmental DNA, Volume 8, Issue 2, March/April 2026.
Key challenges for adoption and scalability of eDNA tools in Southeast Asia. ABSTRACT Environmental DNA (eDNA) has become a transformative tool for biodiversity monitoring and conservation across Southeast Asia, one of the world's most critical biodiversity hotspots.
