Temperature and ultraviolet B radiation (UVB, 280?315 nm) are externalstressors that affect organisms in mid and high latitudes in a combined way. Thecombined effects of both variables on natural marine phytoplankton from the BeagleChannel (Argentina) were examined during a 7-day mesocosm experiment. Wetested the hypothesis that increased temperature (HT, +3 °C) will offset negativeeffects on phytoplankton by UVB (natural, NUVB, and high, HUVB, simulating a60% decrease in stratospheric ozone layer thickness). The response of the entire phytoplanktonassemblage, in terms of phytoplankton biomass, community composition,
