Quadrate orientation and joint reaction force underwent correlated evolution during suchian evolution

open access: yesJournal of Anatomy, EarlyView.
The quadrate is the cranial bone of the nonmammalian jaw joint. The quadrate has long been hypothesized to mirror the direction of joint reaction forces (JRF) during feeding. This study uses 3D biomechanical modeling to reveal a striking evolutionary link between quadrate orientation and JRF direction, unlocking new insights into the dynamic forces ...

Assessing the relative influence of island climatic and geographical factors on body size in an endangered iguana species of the French Caribbean

open access: yesJournal of Zoology, EarlyView.
This study examines the influence of climatic and geographical factors on the body size of iguanas in the Lesser Antilles. We show that iguana body size increases with island size and decreases with distance from the mainland, suggesting that geographical conditions have a greater influence on body size compared to climatic conditions.

Parthenogenic hybrid geckos differ from their sexual counterparts in skin microbiomes but not in rates of water loss

open access: yesJournal of Zoology, EarlyView.
Parthenogenic hybrid populations often have differing morphological, physiological, and ecological traits from their parent populations, which alongside clonal reproduction contribute to increased fitness. However, slowed rates of co‐evolution can reduce parthenogens' capacity to outpace parasites, resulting in higher rates of parasitism.
