UV BUAM egg RAD MORT No effect <strong>of</strong> UV-A was found on eggs or larvae even at<br />

exposures twice the intensity <strong>of</strong> normal outdoor levels. All<br />

embryos exposed for 30 min or more to UV-B died. Exposure<br />

to UV-B for 15 min or less did not affect hatching success.<br />

Grant <strong>and</strong> Licht 1995<br />

UV BUBO egg RAD HATSUC HYRE had highest photolyase active compared to BUBO <strong>and</strong> Blaustein et al. 1994b<br />

RACS.<br />

UV CNEX adult RAD BEHAV 25-60 CNEX acquired as adults exhibited normal behaviour <strong>and</strong><br />

morphology. Those acquired as juveniles <strong>and</strong> maintained<br />

under Vita-Lite exhibited abnormalities in pelvic <strong>and</strong> caudal<br />

regions.<br />

Behler 1987<br />

UV CNSO hatchlings RAD BEHAV 25-60 Lizards exhibited skeletal deformities <strong>and</strong> suffered<br />

spontaneous vertebral fractures <strong>and</strong> posterior paresis as they<br />

grew.<br />

Behler 1987<br />

UV DIWA juvenile RAD BEHAV 25-60 Lizards exhibited skeletal deformities <strong>and</strong> suffered<br />

spontaneous vertebral fractures <strong>and</strong> posterior paresis as they<br />

grew.<br />

Behler 1987<br />

UV HYRE egg RAD HATSUC Highest activity <strong>of</strong> photolyase was found in HYRE compared<br />

to BUBO <strong>and</strong> RACS.<br />

Blaustein et al. 1994b<br />

UV HYVE egg RAD MORT No effect <strong>of</strong> UV-A was found on eggs or larvae even at<br />

exposures <strong>of</strong> twice the intensity <strong>of</strong> normal outdoor levels. All<br />

embryos exposed 30 min. or more to UV-B died.<br />

Grant <strong>and</strong> Licht 1995<br />

UV PLDU egg RAD HATSUC Photolyase activity= < 0.1, sig. less than AMMA <strong>and</strong> AMGR. Blaustein et al. 1994b<br />

UV PLVE egg RAD HATSUC Photolyase activity= < 1.0, similar to AMGR <strong>and</strong> AMMA. Blaustein et al. 1994b<br />

UV RABR embryo RAD DEVOBS room Results similar to RAJA. In both species, sex ratios were<br />

determined at two stages, the first immediately after<br />

metamorphosis <strong>and</strong> the other when the animals matured, as<br />

based on gonad morphology <strong>and</strong> histology <strong>and</strong> on external<br />

sexually dimorphic characters.<br />

stage)<br />

RAD GENOTOX 20 9.5 0.55-3.3 Gy<br />

(gamma rays)<br />

Increase in number <strong>of</strong> micronucleated erythrocytes; younger<br />

tadpoles more sensitive.<br />

UV RACA tadpoles RAD GENOTOX 20 9.5 2.1 Gy (gamma Increase in number <strong>of</strong> micronucleated erythrocytes in early Krauter et al. 1987<br />

rays) stage larvae.<br />

UV RACL egg RAD MORT No effect <strong>of</strong> UV-A was found on eggs or larvae even at<br />

exposures <strong>of</strong> twice the intensity <strong>of</strong> normal outdoor levels. All<br />

embryos exposed 30 min. or more to UV-B died.<br />

Grant <strong>and</strong> Licht 1995<br />

UV RACS egg RAD HATSUC RACS had sig. lower photolyase activity than BUBO <strong>and</strong><br />

HYRE<br />

Blaustein et al. 1994b<br />

UV RAJA egg RAD DEVOBS 40 - 90 % <strong>of</strong> tadpoles had no germ cells, the gonads with no<br />

or few germ cells were remarkably slender at metamorphosis<br />

<strong>and</strong> showed that they were depressed in their development.<br />
