Understanding how growth and reproduction will adapt to changing environmental conditions is a fundamental question in evolutionary ecology, but predicting the responses of specific taxa challenging. Analyses physiological effects climate change upon life history evolution rarely consider alternative hypothesized mechanisms, such as size-dependent foraging risk predation, simultaneously shaping optimal patterns. To test for interactions between these we embedded state-dependent energetic model an ecosystem size-spectrum ask whether prey availability (foraging) predation experienced by individual fish can explain observed diversity histories fishes. We found that asymptotic emerged from size-based reproductive mortality patterns context food web interactions. While more productive ecosystems led larger body sizes, temperature on metabolic costs had only small size. validate our model, ran it abiotic scenarios corresponding ecological lifestyles three tuna species, considering environments included seasonal variation temperature. successfully predicted realistic growth, reproduction, all species. individuals grew when varied seasonally, spawning was restricted part year (corresponding their migration temperate tropical waters). Growing advantageous because opportunities were seasonally constrained. This mechanism could gigantism tunas. Our approach addresses well processes offers promising understand life-history ocean conditions.
