The gill-oxygen limitation theory (GOLT) provides mechanisms for key aspects of the biology
(food conversion efficiency, growth and its response to temperature, the timing of maturation …

Economic models predominate in life history research, which investigates the allocation of
an organism's resources to growth, reproduction, and maintenance. These approaches …

Body size determines total reproductive-energy output. Most theories assume reproductive
output is a fixed proportion of size, with respect to mass, but formal macroecological tests are …

Evolution drives, and is driven by, demography. A genotype moulds its phenotype's age
patterns of mortality and fertility in an environment; these two patterns in turn determine the …

Reproduction includes two energy investments—the energy in the offspring and the energy
expended to make them. The former is well understood, whereas the latter is unquantified …

Comparative studies of mortality in the wild are necessary to understand the evolution of
aging; yet, ectothermic tetrapods are underrepresented in this comparative landscape …

Reproductive Biology of Teleost Fishes is the first integrated review of the reproductive
biology of the bony fishes, which are the most species-rich and diversified group of …

Life history theories attempt to explain the evolution of organism traits as adaptations to
environmental variation. A model involving three primary life history strategies (endpoints on …

We develop a model for somatic growth in fishes that explicitly allows for the energy demand
imposed by reproduction. We show that the von Bertalanffy (VB) equation provides a good …

The hypothesized negative relationship between growth rate and lifespan has proved very
difficult to test robustly because of potentially confounding variables, particularly nutrient …
