Project

Coevolution between Common Cuckoo Cuculus canorus and its hosts adaptations of the Cuckoo chick (IAA6093203)

In this project we intend to examine some prenatal and postnatal adaptations of the brood parasite the Common Cuckoo (Cuculus canorus) facilitating succesfull hatching and development. It has been generally accepted that the hatchin...

A novel system to understand brood parasitism the cuckoo catfish parasitizing African cichlids (GA18-00682S)

Brood parasitism has evolved multiple times in birds and social insect but is remarkably rare in other taxa. An exception is the cuckoo catfish that exploit cost to her brood through predation by early hatching cuckoo catfish offspr...
