Geographic variation in morphology, genetics and behaviour in the granular poison frog, Oophaga granulifera: PhD project at the University of Veterinary Medicine (TiHo) in Hannover (Germany), in collaboration with the Evolutionary Genetics Group, University of Cambridge (UK). Funded by the Volkswagen Foundation.
I am investigating the phenotypic variation on a spatial scale in the poison frog Oophaga granulifera, in Costa Rica. A key point is to explain why colour polymorphism exists in a toxic species, contrary to the expectations of the Mullerian mimicry theory that predicts phenotypic convergence. An intriguing hypothesis is that aposematic and cryptic colour morphs are coexisting. I am evaluating the possible selective pressures underlying the observed differentiation in colour morphs within the rather small distribution range.
Here at the evolutionary genetics group I am specifically trying to elucidate the genetic basis of colour polymorphism in the model species and to quantify the genetics differences between colour morphs using new generation sequencing.
