First reports on the relationship between the eggshell and bone mineralization in Rhinoclemmys punctularia punctularia embryos

open access: yesThe Anatomical Record, EarlyView.
Abstract Composed of various minerals, the eggshell provides ideal conditions for embryonic development, and understanding its composition and structure is essential for clarifying its relationship with bone formation. This study characterized the structure and mineral profile of the Rhinoclemmys punctularia punctularia eggshell in relation to ...

The effect of the sheep dip pesticide diazinon on behavioural and molecular markers in the freshwater shrimp Gammarus pulex [PDF]

open access: yes, 2012
The purpose of this research was to determine the effects of the organophosphorothioate pesticide diazinon, its metabolite diazinon oxon and diazinon in a commercial formulation on the freshwater amphipod Gammarus pulex. It was found that diazinon in the

Osteohistological evidence for terrestrial adaptation and an extended growth period in mekosuchine crocodylians and its potential role in their extinction

open access: yesThe Anatomical Record, EarlyView.
Abstract The Australasian crocodylian fossil record is dominated by the extinct endemic clade Mekosuchinae, with known members spanning the Eocene‐to‐Holocene. This diverse clade exhibited high morphological disparity, from early members superficially similar to Crocodylus, to more terrestrial forms later in the clade's evolutionary history.

Assessment of intraspecific skull variation in the Campanian baenid turtle Plesiobaena antiqua

open access: yesThe Anatomical Record, EarlyView.
Abstract Baenids are freshwater paracryptodiran turtles with a fossil record ranging from the Early Cretaceous to the Eocene. The baenid Plesiobaena antiqua is the most common turtle in the Campanian (Late Cretaceous) Dinosaur Park Formation in Canada, but the apparent intraspecific variation remains poorly understood.

Morphological plasticity in the dentition of the lungfish Gnathorhiza from the Permian of Brazil: A population‐level geometric morphometric analysis

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental plates are pivotal in the lungfish paleontological record, constituting highly mineralized structures resilient to diagenetic processes. This study provides a detailed description and quantitative shape analysis of 95 newly discovered Gnathorhiza sp. dental plates from the Middle–Late Permian Corumbataí Formation, Brazil.

Investigating the Heat Stability and Inactivation Conditions of Decapod Iridescent Virus 1 (DIV1)

open access: yesAnimal Research and One Health, EarlyView.
Heat treatment effectively inactivates decapod iridescent virus 1 (DIV1) under milder conditions than current WOAH recommendations. DIV1 infectivity was eliminated at 56°C for 30 min, 60°C for 15 min, or 70°C for 1 min, providing optimized heat treatment strategies for aquaculture biosecurity and seafood safety.
