About

Variation in venom composition is ubiquitous in snakes, and causes grave problems to snakebite treatment. The underlying drivers and mechanisms of this variation remain poorly understood, particularly the relative importance of diet and gene flow between populations, and the underlying genetic (gene/genome level) mechanisms.

In southwestern USA, the Mohave rattlesnake (Crotalus scutulatus) provides an ideal model system as it displays extreme variation in venom composition across a continuous range. Most populations have venoms rich in highly lethal Mohave toxin (MTX; venom type A), however, some central populations lack MTX but are rich in metalloproteinases (SVMP; type B). Intermediate venom phenotypes are also found (A+B). How and why this variation arises remains insufficiently understood. Together with Wolfgang Wüster and John Mulley, we aim to explore the interaction between venom variation, diet and gene flow, and the underlying genetic mechanisms, particularly whether differences are caused by the presence of absence of toxin genes, or by differences in their expression as toxins.
