Trees with soft wood and thin leaves die of thirst more easily
A study with the participation of researchers from CREAF and the UAB warns that increasing droughts could affect forests’ species composition and structure, making them more vulnerable.

Cities threaten millions of years of bird evolution
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.
Phosphorus, once only a nutrient, has become a contaminant on a global scale
Freshwater ecosystems near densely populated areas have levels of phosphorus which are very high and out of balance with nitrogen levels. This has resulted in altered ecosystem functioning, lower water quality, and has made water conservation more difficult.
