| Abstract | Through natural selection, the environment shapes the survival and reproductive traits of species, including marine fishes. The particular set of life history traits a fish species possesses determine its location in a trilateral continuum of life history strategies. These strategies can be used to understand the dominant biological trade-offs affecting that species, in addition to the gradients of environmental disturbance, variability, and predictability to which it is subjected. Life history strategies can be further subdivided into functional groups differentiated by habitat and feeding preferences. Large predatory fishes can be separated into pelagic specialists and demersal generalists, which are influenced by the separation of primary production into pelagic and benthic secondary production. This life history framework and functional type understanding suggest multiple alterations to fish populations under climate change, including shorter life spans, smaller maximum body sizes, reduced fecundity, greater susceptibility to climate variation impacts, and increased reliance on pelagic food chains. |
