Phenotypic Plasticity Drives Seasonal Thermal Tolerance in a Baltic Copepod.

ABSTRACT: Seasonal changes in environmental conditions require substantial physiological responses for population persistence. Phenotypic plasticity is a common mechanism to tolerate these changes, but for organisms with short generation times rapid adaptation may also be a contributing factor. Here, we aimed to disentangle the impacts of adaptation from phenotypic plasticity on thermal tolerance of the calanoid copepod Acartia hudsonica collected throughout spring and summer of a single year. We used a common garden (11 °C and 18 °C) design to determine the relative impacts of plasticity versus adaptation. Acartia hudsonica were collected from five time points across the season and thermal tolerance was determined using critical thermal maximum (CT_max) followed by ad
