Diversity and development of the hemibacula of croaking geckos (Sphaerodactylidae: Aristelliger)

open access: yesJournal of Anatomy, EarlyView.
Geckos in the genus Aristelliger exhibit enigmatic mineralized elements in their hemipenes, called hemibacula. We examined hemibacula of every species of Aristelliger using μCT, clearing and staining, and histology. We found hemibacula exhibit lineage‐specific morphology, isometric growth after sexual maturity, and are composed of mineralized ...

Intrapopulational variation in head shape correlates with soil structure heterogeneity in a head‐first burrowing amphisbaenian, Trogonophis wiegmanni

open access: yesJournal of Zoology, EarlyView.
Morphological traits evolve to solve ecological requirements. Amphisbaenians are fossorial reptiles with different snout shapes for burrowing head‐first underground, but how these head shapes have originated is little known. Here, using 2D geometric morphometrics, we found that individual Trogonophis wiegmanni amphisbaenians inside the same population ...

Intraspecific variation and detectability of iridescence in the dorsal coloration of a wall lizard

open access: yesJournal of Zoology, EarlyView.
Wall lizards (genus Podarcis) show substantial intraspecific colour variation and iridescence, which may interact and affect overall colour appearance. Here, we set out to study iridescence in Podarcis liolepis in two localities in which lizards are known to differ in dorsal coloration. Our results show that P.
