Manon's profile picture

I am fascinated by the evolutionary mechanisms that shape the natural world. Most specifically by what happens when species become threatened, or populations become isolated. When species adapt to their changing environments, it sometimes happens that nature - oddly enough - "fools" itself as a result of basic, evolutionary principles. Thus, as a PhD candidate I currently work on explaining how a weird, evolutionary flaw in crested and marbled newts of the genus Triturus evolved. My project is a collaboration between Naturalis and the Institute of Biology Leiden (IBL). Next to this project, I am also involved with nature conservation, (genetically) monitoring exotic amphibians and telling the stories of our researches through 'scicomm'.

Balanced
Lethal Systems

Photo of a crested newtI am a member of the Wielstra lab (ERC Starting Grant-funded research), where we study the genomics underlying the best-known case of a balanced lethal system: chromosome 1 syndrome in Triturus newts. Balanced lethal systems are considered an evolutionary failure, because natural selection is unable to get rid of the associated recessive, lethal alleles. I investigate the lethality and evolutionary origin of this system in collaboration with IBL. Are you curious to find out more? Just click here to read about balanced lethal systems!
 

Science
Communication

What is it like to work as a PhD in the field of genomics, for both Naturalis and the University of Leiden? And what do I actually learn from the salamanders - and other animals - that I study? I find it important to share my knowledge and experiences with the world!
