abstract = {Global-change stressors act under diferent timing, implying complexity and uncertainty in the
study of interactive efects of multiple factors on planktonic communities. We manipulated three
types of stressors acting in diferent time frames in an in situ experiment: ultraviolet radiation (UVR);
phosphorus (P) concentration; temperature (T) in an oligotrophic Mediterranean high-mountain lake.
The aim was to examine how the sensitivity of phytoplankton and bacterioplankton to UVR and their
trophic relationship change under nutrient acclimation and abrupt temperature shifts. Phytoplankton
and bacteria showed a common pattern of metabolic response to UVR× P addition interaction, with an
increase in their production rates, although evidencing an inhibitory UVR efect on primary production
(PP) but stimulatory on bacterial production (HBP). An abrupt T shift in plankton acclimated to UVR and
P addition decreased the values of PP, evidencing an inhibitory UVR efect, whereas warming increased
HBP and eliminated the UVR efect. The weakening of commensalistic and predatory relationship
between phyto- and bacterioplankton under all experimental conditions denotes the negative efects
of present and future global-change conditions on planktonic food webs towards impairing C fux within
the microbial loop.},
