A study led by Daniel Sol, CISC researcher based at CREAF, shows that cities preserve 450 million years less evolutionary history compared to natural environments. Birds capable of surviving in highly urbanized environments have undergone recent evolution. The arrival of exotic species does not compensate for poor urban evolutionary diversity.
The data base of the research project EXOCAT, commissioned by the Catalonian government and coordinated by CREAF, has more than 1,100 exotic species registered in Catalonia, 111 of which are considered as invasive. This data base is a benchmark tool for improving policy on biological invasions and their control.
Parrots at public parks and gulls flying landfills. Those are examples of some birds that have found the ideal place to live in our cities. We are increasingly demanding to create urban infrastructures and offer better services to citizens, but we are indirectly creating a new ecosystem for urban birds.
