Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

open access: yesIntegrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Endocranial anatomy of the earliest Cretaceous European neosuchian crocodyliform Pholidosaurus purbeckensis provides new evidence for the ecological evolution of Pholidosauridae

open access: yesJournal of Anatomy, EarlyView.
We present new insights into the internal cranial anatomy of the neosuchian crocodyliform Pholidosaurus purbeckensis, based on CT‐scan data of material from the lowermost Cretaceous Purbeck Limestone Group, southern UK. From the study of the endocast, we obtained new information on the phylogeny and the ecological evolution of the Family ...
