Ectotherms typically increase growth and reduce body size when temperature increases. This physiological response to temperature, termed the temperature-size rule (TSR), is often used to predict how rising temperatures with climate change will affect higher levels of organization, i.e. guilds, communities and ecosystems. Here we study whether faster growth and reduction in adult body size are observed with temperature across marine fish in natural communities from polar to tropical regions. We find no effect of increasing temperature on the average asymptotic body length of fish species present in ecosystems and only a limited increase in average growth of fish species in warmer systems.
