The fitness consequences of age-dependent changes in cognitive abilities
Description: This project aims to investigate health-related topics in invasive fish. The evolution of large brains suggests that smarter individuals have more offspring due to natural and sexual selection. This project aims to test if the ability to perform cognitively challenging tasks predicts reproductive success. In addition, many life history traits show a trade-off between early and late life performance. This project will test this prediction to see if individuals with above average cognitive performance when young are below average when old, that is faster 'cognitive senescence', or whether some individuals stay relatively smarter than others throughout their lives.
