Data from: Brain size affects the behavioral response to predators in female guppies (Poecilia reticulata)

Wouter Van Der Bijl, Malin Thyselius, Alexander Kotrschal & Niclas Kolm
Large brains are thought to result from selection for cognitive benefits, but how enhanced cognition leads to increased fitness remains poorly understood. One explanation is that increased cognitive ability results in improved monitoring and assessment of predator threats. Here, we use male and female guppies (Poecilia reticulata), artificially selected for large and small brain size, to provide an experimental evaluation of this hypothesis. We examined their behavioural response as singletons, pairs or shoals of four...
