**1.** Growth rates directly influence individual fitness and constrain the flow of energy within food webs. Determining what factors alter the energetic cost of growth is therefore fundamental to ecological and evolutionary models. **2.** Here, we used theory to derive predictions about how the cost of growth varies over ontogeny and with temperature...
Our findings suggest that body size distribution, reef area, and temperature are major predictors of species richness and accumulation across scales, consistent with recent theories linking home range to species-area relationships as well as metabolic effects on speciation rates. Based on our results, we hypothesise that in less diverse areas, species are larger and likely more dispersive, leading to larger range sizes and less turnover between sites...
The allocation of metabolic energy to growth fundamentally influences all levels of biological organisation. Here we use a first‐principles theoretical model to characterise the energetics of fish growth at distinct ontogenetic stages and in distinct thermal regimes...
