Constrained or strategic? Causes and consequences of variation in self-maintenance in wild birds. To live long and healthy lives, animals must defend themselves from diseases and repair damage due to wear and tear. This project will address what prevents animals from achieving optimal defences, and what the consequences are for ageing and survival.
Can consistent individual differences in metabolic rate explain animal personality? Implications for fish and aquaculture in a warming climate. This project will determine if consistent individual differences in metabolic rate affect behaviour, growth, and reproduction in fish. If so, then we need to prepare for the fact that a warming climate will lead to reductions in fish growth and reproduction, because rising temperature directly increases metabolism and therefore maintenance costs.
