Shifts in type 2 vomeronasal receptor expression during postnatal development in the lungfish olfactory organ

open access: yesJournal of Anatomy, Volume 249, Issue 4, Page 978-986, October 2026.
Lungfish possess a lamellar OE and a primitive VNO called as a recess epithelium (RecE). Among the lungfish V2Rs expressed in both the lamellar OE and the RecE in small individuals, some became restricted to the RecE in large individuals. These results suggest functional separation between the lamellar OE and the RecE is still incomplete in juveniles ...

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe Anatomical Record, Volume 309, Issue 9, Page 2315-2330, September 2026.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Stable oxygen isotopes of crocodilian tooth enamel allow tracking Plio-Pleistocene evolution of freshwater environments and climate in the Shungura Formation (Turkana Depression, Ethiopia) [PDF]

open access: yesBiogeosciences
This study adopts a new approach describing palaeohydrology and palaeoclimates based on the interpretation of stable oxygen isotopes (δ18Op) recorded in fossil crocodilian teeth.

In‐vitro puncture experiment using alligator teeth tracks the formation of dental microwear and its association with hardness of the diet

open access: yesThe Anatomical Record, Volume 309, Issue 9, Page 2424-2441, September 2026.
Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

Biophysical processes of morphogenesis in lizard lungs

open access: yesDevelopmental Dynamics, Volume 255, Issue 9, Page 867-880, September 2026.
Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.

A Scoping Review: The Effect of Anthropogenic Noise on Animal Welfare in Zoological Settings

open access: yesVeterinary Medicine and Science, Volume 12, Issue 5, September 2026.
This scoping review was conducted to determine the impact of anthropogenic noise on animal welfare in zoological settings and identify knowledge gaps. Some studies found a negative impact with increased vigilance as a common behavioral change. A small number of studies evaluated physiological changes. Though other factors could be involved.

Fossils as cultural heritage: Scientific, commercial and legislative issues

open access: yesGeology Today, Volume 42, Issue 5, Page 263-272, September/October 2026.
Fossils are among the principal sources for understanding the history of life through ‘Deep Time’ and can inform projections of biotic responses to environmental change. Despite a widespread recognition of the scientific, historical and communication significance of fossils in our culture, their role as part of our cultural heritage is still far from ...

Completing the first molecular and morphological characterised life cycle of a crocodilian-infecting diplostomid, Neofibricola smiti (Digenea: Diplostomidae)

open access: yesParasitology
The life cycles of trematodes infecting crocodilians remain poorly understood, with most species known exclusively from adult stages recovered from definitive hosts.
