             abstract = "The increased incidence of solar ultraviolet radiation (UV) due to 
                         ozone depletion has been affecting both terrestrial and aquatic 
                         ecosystems and it may help to explain the enigmatic decline of 
                         amphibian populations in specific localities. In this work, 
                         influential events concerning the Antarctic ozone hole were 
                         identified in a dataset containing 35 years of ozone measurements 
                         over southern Brazil. The effects of environmental doses of UVB 
                         and UVA radiation were addressed on the morphology and development 
                         of Hypsiboas pulchellus tadpole (Anura: Hylidae), as well as on 
                         the induction of malformation after the conclusion of 
                         metamorphosis. These analyzes were complemented by the detection 
                         of micronucleus formation in blood cells. 72 ozone depletion 
                         events were identified from 1979 to 2013. Surprisingly, their 
                         yearly frequency increased three-fold during the last 17 years. 
                         The results clearly show that H. pulchellus tadpole are much more 
                         sensitive to UVB than UVA light, which reduces their survival and 
                         developmental rates. Additionally, the rates of micronucleus 
                         formation by UVB were considerably higher compared to UVA even 
                         after the activation of photolyases enzymes by a further 
                         photoreactivation treatment. Consequently, a higher occurrence of 
                         malformation was observed in UVB-irradiated individuals. These 
                         results demonstrate the severe genotoxic impact of UVB radiation 
                         on this treefrog species and its importance for further studies 
                         aimed to assess the impact of the increased levels of solar UVB 
                         radiation on declining species of the Hylidae family.",
