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.

Singing in higher pitches is no guarantee of success for city birds

An international study with participation of CREAF has concluded that singing in higher pitches is no guarantee of success for city birds. This was after observing city-dwelling birds in around 20 cities worldwide, Barcelona being one of them. The researchers compared around 400 species and analyzed whether these were more abundant in their natural habitat or in urban areas.
