Cities threaten millions of years of bird evolution

31 de May 2017Anna Ramon Revilla

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.

Birds that live in changing environments have larger brains

16 de January 2017Albert Naya i Díaz

A large brain increases the capacity to adjust behavior to new circumstances through learning, improving resource-gathering in a changing environment. Greater understanding of this capacity can improve predictions of what species of birds and other animals will be most vulnerable to global change.

Birds provide us with the clues to understanding human creativity

10 de May 2016Anna Ramon Revilla

An analysis of 1018 bird species led by CREAF and CSIC scientists suggests that innovation is not just an adaptation on it own, but emerges with the combination of certain adaptations which developed for dealing with changes in the environment, including having a large brain and being curious. Primates, cetaceans, parrots, and crows innovate because they have long lifespans and are adapted to living in changing environments.

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

20 de November 2015Laia Núñez Casillas

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. What is certain is that species which sing at higher pitches are heard better against the low tones of the city, but there are other abilities which are more important when adapting to urban life, such as finding food and avoiding urban dangers.

Daring to live on the edge

21 de July 2014CREAF

Around the world, invasive animal species are pushing out the natives, sometimes forever altering ecosystems. House sparrows are a prime example, having spread from Europe to most inhabited parts of the world.  Daniel Sol has collaborated in an dissemination article  for the Science journal that have gleaned key traits underlying its incredible success.
