Webb6 aug. 2013 · Finally, we show linkages between physiology and life-history attributes of larks along an aridity gradient; birds from deserts have not only a reduced rate of metabolism but also a small clutch size and slow nestling development. Hence, attributes of physiology are correlated with traits that directly affect reproductive success.

WebbMammals and birds keep their body temperatures between 37°C and 38°C; however there are exceptions (Walsberg, 2000). Maintaining a constant internal temperature requires animals to have mechanisms to regulate their body temperature. This is challenging for desert animals due to the extreme heat and lack of water.
