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.

With a few biological traits we can predict if two species interact

This study, in which the CREAF participated, determined that relationships between species follow a few common patterns, and, therefore, with little data a lot of detail can be understood regarding the ecological networks of ecosystems and predict a species’ evolution in the face of perturbations.
