Description:
Different studies have demonstrated that solar ultraviolet (UV) radiation can adversely affect survival and development of embryonic and larval amphibians. However, because of among-laboratory variations in exposure profiles (artificial vs. natural sunlight; natural sunlight at different latitudes/elevations under variable weather conditions), it has been difficult to perform quantitative assessments of exposure-response relationships across different species or life stages. The purpose of this work was to develop a test system suitable for generating high quality data for deriving these types of exposure-response relationships. To achieve this, it was necessary that the system quantitatively and qualitatively imic full-spectrum sunlight, and also meet the biological requirements of different stages of different species of amphibians. The basic test system is a commercally-available solar simulator (Q-Sun), with a step-wise diurnal intensity simulation program, that we refined for temperature-controlled aqueous exposures with up to 27 discrete test chambrers. - - -
