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.

该项目旨在调查入侵鱼类的健康相关主题。大大脑的进化表明，由于自然选择和性选择，更聪明的个体会有更多的后代。该项目旨在测试执行具有认知挑战性的任务的能力是否可以预测生殖成功。此外，许多生活史特征显示出早期和晚期生活表现之间的权衡。该项目将测试这一预测，看看年轻时具有高于平均水平的认知表现的个体在年老时是否低于平均水平，即更快的“认知衰老”，或者是否有些人在一生中都比其他人相对聪明。
