This project plans to examine the novel hypothesis that mammals and birds can control and minimise their evaporative water loss in dry environments. Water balance is fundamental for the survival of mammals and birds. As a large component of total water loss, evaporative water loss is particularly critical for species in arid habitats and areas undergoing desertification and other habitat modifications. Control of water loss is a previously unappreciated ability in mammals and birds. Determining the mechanistic basis for evaporative homeostasis would fundamentally change our knowledge of animal function, and may help us to predict and understand the effects of environmental change on survival and distribution limits for Australian fauna.

这个项目计划检验一种新的假设，即哺乳动物和鸟类可以在干燥环境中控制和最小化它们的蒸发水分损失。水平衡对哺乳动物和鸟类的生存至关重要。作为总水分损失的一个重要组成部分，蒸发水分损失对干旱生境和正在经历荒漠化和其他生境改变的地区的物种尤其重要。哺乳动物和鸟类控制水分流失的能力以前没有得到重视。确定蒸发稳态的机制基础将从根本上改变我们对动物功能的认识，并可能帮助我们预测和理解环境变化对澳大利亚动物群生存和分布限制的影响。
