Evolutionary Links Between Skull Shape and Body Size Suggest Allometric Forces and Selection at Work in a Generalist Group of Lizards

Ecology and Evolution, Volume 14, Issue 11, November 2024.
We use geometric morphometrics and phylogenetic comparative methods to study skull shape evolution in Sceloporus lizards. We found that overall body size is driving shape evolution; however, sexual selection seems to play a role. Moreover, the skull has evolved as a single unit with little modularity occurring.

Macroevolutionary diversification of glands for chemical communication in squamate reptiles [PDF]

, 2017
Chemical communication plays a central role in social, sexual and ecological interactions among animals. However, the macroevolutionary diversification of traits responsible for chemical signaling remains fundamentally unknown.

Arthropods to Eutherians: A Historical and Contemporary Comparison of Sparse Prenatal Microbial Communities Among Animalia Species

American Journal of Reproductive Immunology, Volume 92, Issue 2, August 2024.
ABSTRACT Since the advent of next‐generation sequencing, investigators worldwide have sought to discern whether a functional and biologically or clinically relevant prenatal microbiome exists. One line of research has led to the hypothesis that microbial DNA detected in utero/in ovo or prior to birth/hatching is a result of contamination and does not ...

Factors affecting microhabitat use in two agamid species from south‐eastern Australia

Austral Ecology, Volume 49, Issue 7, July 2024.
Radio‐tracking of mallee tree dragons (Amphibolurus norrisi) and painted dragons (Ctenophorus pictus) revealed rare insights into the factors influencing microhabitat use. We document shifts in microhabitat use associated with varying thermal environments and identified a possible ontogenetic shift in mallee tree dragons, where juveniles begin their ...
