Anatomische Anpassungen des Atmungssystems des Apothekerskinks (Scincus scincus)

沙鱼（学名：Scincus scincus）是一种蜥蜴，它具有在沙漠中以游泳的方式移动的非凡能力，当淹没在沙子中时，它可以以惊人的速度移动很长的距离。不同的形态、生理和行为特征使其在进化过程中很好地适应了松散的风沙环境。在过去的几年里，我们可以澄清不同方面的摩擦减少和耐磨外皮和运动的沙鱼。这个迷人的动物的一个方面仍然是谜是呼吸。到目前为止，人们还不清楚沙鱼是如何在半米深的细而松散的风成沙中呼吸的。为了阐明这个问题，我们计划测量取决于其运动活动的沙鱼的耗氧量。进而确定风成沙气体交换抑制的定量参数。此外，我们还想弄清楚肺和呼吸道的确切形态，以了解是否发生了特殊的形态适应。所有这些调查都将在沙鱼物种以及密切相关的蜥蜴石蜥（Eumeces schneiderii）上进行，石蜥不进行沙泳。这种比较应该允许确定特定的适应所造成的适应沙游泳。

The sandfish (Scincus scincus) is a lizard having the remarkable ability to move in desert sand in a swimming-like fashion over significant distances at remarkable velocities when submerged in sand. It is well adapted through evolution to live in loose aeolian sand by different morphological, physiological and behavioral features. In the last years we could clarify different aspects of the friction reducing and abrasion resistant integument and of the locomotion of the sandfish. One aspect of this fascinating animal that is still enigmatic is the breathing. It is till now unclear how the sandfish manages to breath in fine, loose aeolian sand at depth down to about half a meter. To shine light on this question we plan to measure the oxygen consumption of the sandfish dependent on its locomotive activity. Furthermore we want to determine quantitative parameters for the hinterance of gas exchange of the aeolian sand. Additionally we would like to clarify the exact morphology of the lungs and of the respiratory duct in order to see if special morphological adaptations have developed. All these investigations will be carried out on sandfish species as well as on the closely related lizard Eumeces schneiderii, which does not perform sand swimming. This comparison should allow determination of specific adaptations caused by the adaptation to sand swimming.
