Climate change is expected to change temperature regimes though multiple avenues such as increasing maximal environmental temperatures as well as frequency of daily maximum temperatures, which has been relatively understudied to the former. This study examines the chronic effect of heat stress due to higher frequencies of current daily maximum temperature on lifespan of two populations the intertidal marine copepod Tigriopus californicus with vastly different thermal tolerances. This study applied different heat stress regimes to the two populations and monitored their survival for the entirety of their lifespan. Our results show that frequency of heat stress impacts lifespan.
