This project will investigate the physiology and structure of Australian fishes that use gills and breathe air. It will measure the partitioning of oxygen and carbon dioxide exchange between the aquatic (gills) and aerial (lung, swim-bladder or mouth) respiratory organs, in relation to dissolved oxygen in the water and metabolic energy demands by the fish. Rates of gas exchange, biochemical characteristics of the blood, anatomy and physiology of the exchange organs, and respiratory/locomotory coupling will be measured in three selected species during graded exercise. The results will help us understand the factors influencing the evolution of air-breathing.

该项目将研究使用鳃和呼吸空气的澳大利亚鱼类的生理和结构。 它将测量水生（鳃）和空气（肺，鱼鳔或嘴）呼吸器官之间的氧气和二氧化碳交换分配，与水中溶解的氧气和鱼的代谢能量需求有关。 在分级运动期间，将在三个选定物种中测量气体交换率、血液生化特征、交换器官的解剖学和生理学以及呼吸/运动耦合。 这些结果将有助于我们了解影响空气呼吸演变的因素。
