Published in 2022 at "Journal of Morphology"

DOI: 10.1002/jmor.21508

Abstract: A snake‐like body plan and burrowing lifestyle characterize numerous vertebrate groups as a result of convergent evolution. One such group is the amphisbaenians, a clade of limbless, fossorial lizards that exhibit head‐first burrowing behavior. Correlated… read more here.

Published in 2024 at "Human Reproduction"

DOI: 10.1093/humrep/deae108.504

Abstract: Which technique is more effective for new embryologists in human oocyte Piezo-ICSI: Head-first or tail-first injection? Tail-first injection is superior as it significantly increases fertilization rates without adversely affecting embryo development compared to head-first injection… read more here.

Published in 2025 at "Journal of Zoology"

DOI: 10.1111/jzo.70008

Abstract: Morphological traits of animals have evolved to solve ecological requirements, the optimization of locomotion in each environment being one of the most frequent selective forces shaping morphology. Amphisbaenians are strictly fossorial reptiles that have evolved… read more here.
