Ultraviolet (UV) radiation has detrimental effects on marine ecosystems, in particular in the polar regions where stratospheric ozone reduction causes higher levels of solar radiation. We analyzed two polar species of Euplotes, Euplotes focardii and Euplotes nobilii, for the sensitivity to UV radiation in comparison with two akin species from mid-latitude and tropical waters. Results showed that they face UV radiation much more efficiently than the non-polar species by adopting alternative strategies that most likely reflect different times of colonization of the polar waters. While E. focardii, which is endemic to the Antarctic, survives for longer exposed to UV radiation, E. nobilii, which inhabits both the Antarctic and Arctic, recovers faster from UV-induced damage.

Abstract
Ultraviolet (UV) radiation has detrimental effects on marine ecosystems, in particular in the polar regions where stratospheric ozone reduction causes higher levels of solar radiation. We analyzed two polar species of Euplotes, Euplotes focardii and Euplotes nobilii, for the sensitivity to UV radiation in comparison with two akin species from mid-latitude and tropical waters. Results showed that they face UV radiation much more efficiently than the non-polar species by adopting alternative strategies that most likely reflect different times of colonization of the polar waters. While E. focardii, which is endemic to the Antarctic, survives for longer exposed to UV radiation, E. nobilii, which inhabits both the Antarctic and Arctic, recovers faster from UV-induced damage.File | Dimensione | Formato | |
