Population and community dynamics: The dynamics of structured populations with respect to intra- and interspecific interactions such as predation, cannibalism, competition, and the effect of abiotic environmental factors, specifically temperature.
Life-history traits: Selective pressures shaping life-history evolution, for instance the evolutionary response of populations to increased mortality rates caused by exploitation or pathogens.
Ecological diversification: Ecological factors facilitating evolutionary divergence and the traits involved in adaptive diversification, particularly metabolic adaptation along environmental temperature gradients.
Metabolic scaling: Effects of temperature on the scaling of metabolic rate with body mass, and how fish species differ in metabolic scaling exponents.
Swimming energetics: The energetics of fish swimming, especially the effects of temperature, body size and morphology on standard and active metabolic rates.
