Amphibian decline is not a phenomenon unique to overseas continents and countries. In the long line of research papers addressing this issue in the best science journals (e.g., Nature and Science), Australian frog decline has even been singled out for specific coverage. This project targets the interplay between habitat fragmentation, loss of genetic variation (inbreeding), and its effects on UV and pathogen resistance in a laboratory model system. It integrates three disciplines (immunobiology, evolutionary genetics, and conservation biology) to resolve fundamental aspects of the drastic, ongoing disappearance of the most significant ecological indicator taxa known today (amphibians).

两栖动物的减少并不是海外大陆和国家独有的现象。在最好的科学期刊上发表的一长串研究论文中（例如，《自然》和《科学》），澳大利亚青蛙的减少甚至被挑出来进行专门报道。该项目的目标是栖息地破碎化，遗传变异（近亲繁殖）的损失，其对紫外线和病原体抗性在实验室模型系统的影响之间的相互作用。它整合了三个学科（免疫生物学，进化遗传学和保护生物学），以解决当今已知的最重要的生态指示分类群（两栖动物）急剧，持续消失的基本方面。
