Why do so many species undergo a metamorphosis during their life where individuals abruptly change their morphology, behavior and habitat? Not only butterflies and frogs have a metamorphosis, also many marine invertebrates, fish species (e.g. flatfish) and crustaceans (e.g. lobsters) drastically change their morphology during their life. Although metamorphosis is widespread in the animal kingdom, it is not well understood under which conditions this strategy has evolved. While metamorphosing species can efficiently exploit multiple habitats during their life, metamorphosis is also very costly. Metamorphosing species are for example often dependent on multiple habitats for their growth and reproduction. When one of the habitats deteriorates the population might go extinct. Some species have lost metamorphosis via the evolution of direct development or paedomorphosis.
I am interested under which ecological conditions metamorphosis can evolve and disappear. Life-history strategies such as metamorphosis, direct development and paedomorphosis evolved millions of years ago. The ecological conditions under which those strategies have evolved have most likely changed since then. I make use of size-structured population models to better understand the ecological conditions that promoted the evolutionary gain and loss of metamorphosis.
