Most recently, a study on the endangered common smooth-hound shark has documented recurrent parthenogenesis, thereby expanding the spectrum of vertebrates known to utilise this reproductive ...

The Komodo dragon, a venomous giant lizard native to Indonesian islands, faces endangerment with fewer than 6,000 remaining.

Facultative parthenogenesis allows female sharks to ... Chondrichthyans have existed far longer than most other vertebrates, and their diverse reproductive methods may explain their resilience.

Background. Understanding the functional role(s) of the more than 20,000 proteins of the vertebrate genome is a major next step in the post-genome era. The approximately 4,000 co-translationally ...

Challenges in imaging lipid-processing events in live, intact vertebrate models have historically led to reliance on cultured cell studies, thus hampering our understanding of lipid metabolism and ...
