Bio: John Smout (research technician)

John is now a research technician contributing to our NERC Pushing the Frontiers project on the sex-specific fitness consequences of oviparity and viviparity in common lizards

----

John Smout was a PhD student funded through the University of Glasgow’s MVLS Doctoral Training Programme. His PhD project addressed the genetic and cellular basis of oviparity and viviparity using the common lizard, Zootoca vivipara, as a model for the transition between reproductive modes in squamates in other amniotes. John was co-supervised by Mark McLaughlin and Maureen Bain.

My general research interests centre on the application of new technologies and new molecular biology techniques to address important questions in ecology and evolution. I first attended the University of Glasgow as an MSc student in 2017, completing a master’s project with Elmer Lab on field-based qPCR genotyping of common lizards (Zootoca vivipara) in summer 2018. In 2019 I was accepted to join the MVLS DTP and began work on culturing Z. vivipara primary oviduct cells for use in experiments on the genetics of reproductive mode in this species. 

My PhD project addresses the genetic and cellular basis of viviparity (live birth) and oviparity (egg laying) in lizards and other amniotes. The evolution of viviparity from oviparity represents a major innovation in amniote life history, but the cellular and molecular changes that underlie this transition are presently poorly understood. The majority of oviparity-viviparity transitions have occurred in squamate reptiles (snakes, lizards, and their relatives), more than in all other amniote lineages. Z. vivipara is highly unusual as this species is reproductively bimodal, with both oviparous and viviparous lineages, allowing for comparisons between oviparity and viviparity in otherwise genetically similar animals. My research exploits this remarkable model system to study the genetic and cellular foundations of this important evolutionary transition.

NEW PAPER: landscape genomics reveal that oviparous and viviparous lizards have innately different population patterns

Image
In a neat mix of some spatial genetic autocorrelation analyses (which I got excited about during my PhD on leaf litter frogs ) and life history strategies, we have published a new paper on oviparous and viviparous lizards. We find that even in the same environment, ie at the same site, the different parity modes have different scales of dispersal and different population densities. See details below. To do this study we reanalysed population level data collected in the study Hans led on the genomic basis of parity mode phenotypes now looking only at pure ovi/vivi individuals. This is unusual because most often these lineages are found in very different environments, which is a confound if we wanted to explore contrasts in their life histories and demographies. Parity-specific differences in spatial genetics and dispersal in the common lizard Abstract: Dispersal is a key demographic parameter that plays an important role in determining spatial population dynamics and genetic structure....

New paper: Review paper on epigenetics in colouration

Image
 New paper from final year PhD student Nic Strowbridge. Nic's PhD looks at epitranscriptomics in different skin colour of salamanders. Methylation is a top new topic spurred on by advances in sequencing technology (which Nic is also using!) Using that momentum and finding lots of literature gap, Nic led this excellent and topical review paper. Check it out here - Open access!  Nicholas Strowbridge, David R. Vieites, Michael G. Ritchie, Kathryn R. Elmer. 2025. Contributions of epigenomic and epitranscriptomic methylation to animal colouration. Trends in Genetics  Abstract Due to its high variation and its diversity of functional roles, animal colouration has long been a fascinating phenotype for geneticists. While the loci underpinning colour are relatively well known, there remain components of unexplained variation. The contribution of DNA and RNA methylation to these molecular mechanisms of colouration is only now being explored. Recent research has shown that DNA (m 5...

New paper: life-history trade-offs of oviparity and viviparity

Image
Congratulations to Hans and our newest paper - "Differential reproductive investment in co-occurring oviparous and viviparous common lizards ( Zootoca vivipara ) and implications for life-history trade-offs with viviparity". A strength of this study is that it compares oviparity and viviparity reproduction from within the same geographic area and between sister lineages, therefore minimising the effects of environment and phylogeny. The paper is available open access from here, in Oecologia https://rdcu.be/bAGx7 Abstract Live-bearing reproduction (viviparity) has evolved from egg-laying (oviparity) independently many times and most abun-dantly in squamate reptiles. Studying life-history trade-offs between the two reproductive modes is an inherently difficult task, as most transitions to viviparity are evolutionarily old and/or are confounded by environmental effects. The common lizard ( Zootoca vivipara ) is one of very few known reproductively bimodal species, in which...
