Annika Wreth PhD

I am a PhD student in Niclas Kolm´s lab. The overall aim with my PhD project is to investigate variation in brain anatomy and schooling behaviour as potential mechanisms causing individual variation in cognitive ability and thereby, presumably driving cognitive evolution. More specific, I will evaluate how rapid changes in these traits affect especially learning and memory in individual and collective contexts. For this, I will use guppies (Poecilia reticulata) artificially selected for either relative brain size or schooling behaviour.
