Selection and trans-species polymorphism of major histocompatibility complex class II genes in the order Crocodylia. [PDF]
PLoS ONE, 2014 Major Histocompatibility Complex (MHC) class II genes encode for molecules that aid in the presentation of antigens to helper T cells. MHC characterisation within and between major vertebrate taxa has shed light on the evolutionary mechanisms shaping the

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs. [PDF]
Anat Rec (Hoboken)Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

Clustering crocodylian dental morphology: Insights into functional adaptations, diet, and ontogeny. [PDF]
J AnatExtant crocodylians may be divided into five clusters based on the residuals of four linear dental measurements (y‐axes) and their variation along the jaw (x‐axes). These clusters correlate to snout shape, prey preference, and feeding ecology, particularly prey size and the degree of processing necessary. Multiple families and subfamilies were found in

The pseudosuchian record in paleohistology: A small review. [PDF]
Anat Rec (Hoboken)Abstract Archosauria originated around the Earth's largest biotic crisis that severely affected all ecosystems globally, the Permotriassic Mass extinction event, and comprises two crown‐group lineages: the bird‐lineage and the crocodylian lineage. The bird lineage includes the iconic pterosaurs, as well as dinosaurs and birds, whereas the crocodylian ...

Early life differences in behavioral predispositions in two Alligatoridae species. [PDF]
Anim Cogn, 2021 Behavioral predispositions are innate tendencies of animals to behave in a given way without the input of learning. They increase survival chances and, due to environmental and ecological challenges, may vary substantially even between closely related ...
