Climate change could leave freshwater fish with bigger brains but a reduced ability to effectively explore their surroundings, scientists have found.
In order to survive, the world’s aquatic life will need to adapt to the warmer waters which global heating will produce in the coming decades.
New research by University of Glasgow biologists suggests that the physiological changes fish will undergo in warmer rivers might require them to trade brains for brawn, with potentially challenging consequences.
In order to test how living in warmer waters might affect cold-blooded freshwater fish, researchers from the University’s Institute of Biodiversity Animal Health & Comparative Medicine fished minnows from the River Kelvin, close to the University, and split them into two groups.
