Abstract

Climate change challenges marine species with seawater that is warmer, with less oxygen and lower pH. To date, most climate-change studies have focused on organismsí acclimation or shifts in distribution; relatively little is known about the capacity of marine species to respond through evolution. We propose that important insights can be gained from recent studies of fishery-induced evolution (FIE), which show that increased adult mortality from fishing leads to rapid changes in growth and reproduction schedules. These changes consistently involve evolution of "faster" life histories: earlier maturation at smaller sizes and shorter life spans. In the ocean, coupled effects of higher temperatures and reduced oxygen also differentially affect larger or older individuals, so expected evolutionar y consequences of climate change are qualitatively similar to those of FIE. This general pattern will apply to large numbers of marine species and has important implications for conservation and management.
