Beskrivning av projektet
Understanding diversity is one of the main goals of evolutionary biology, and the evolution of diversity in aposematic organisms (i.e. those who use warning signals to warn predators of their unprofitability or toxicity) is particularly challenging to explain. Natural selection should favour uniform, bright warning signals since bearing a common signal and being easily recognizable to predators confers a survival advantage. So why, then, do multiple forms of signals persist in aposematic species? The answer could be that evolution rarely acts through a single mechanism like predation. The goal of this proposal is to explore what factors interact to maintain warning signal diversity. I will study colour diversity in the wood tiger moth (Parasemia plantaginis) using the power of population biology, experimental evolutionary ecology, genetics, and theoretical modelling. This study will serve as an example of how complex interactions of evolutionary processes maintain biological diversity.
