Effects Of Ultraviolet Radiation And Visible Light On The Development Of Encapsulated Molluscan Embryos, Rachel Przeslawski, Andrew R. Davis, Kirsten Benkendorff
Faculty of Science, Medicine and Health - Papers: part A
Benthic egg masses laid in intertidal habitats are exposed to numerous environmental stresses including potentially damaging ultraviolet radiation (UVR). We sought to determine the developmental effects of UVR and visible light on molluscan embryos within egg masses from habitats with differential UVR exposure. Capsular and gelatinous egg masses from 23 marine gastropod species were collected from 3 intertidal habitats: (1) full sun, (2) partial shade, and (3) full shade. Egg masses were then divided among 4 spectral treatments: full spectrum, no UV-B, no UV, and dark. An ANOVA confirmed that a significant interaction between original habitat and spectral treatment affected …
