...Philipp Comanns; Philip C. Withers; Falk J. Esser; Werner Baumgartner ABSTRACT Moisture-harvesting lizards, such as the Australian thorny devil, Moloch horridus , have the remarkable ability to inhabit arid regions. Special skin structures, comprising a micro-structured surface with capillary...

... by an increase in structures supporting oxygen delivery and consumption, such as capillaries and mitochondria. High-load strength-type exercise leads to growth of muscle fibers dominated by an increase in contractile proteins. In endurance exercise, stress-induced signaling leads to transcriptional upregulation...

... of the `total effective surface' of mitochondria and capillaries. According to these models, basal and maximal metabolic rates must scale as M 3/4 . This is not what we find. In 34 eutherian mammalian species (body mass M b ranging from 7 g to 500 kg) we found V̇ O 2max to scale with the 0.872 (±0.029) power...

... kangaroo mitochondrial oxygen consumption at V̇ O 2 max was 4.7 ml O 2 min –1 ml –1 of mitochondria. Also, the inner mitochondrial membrane densities were 35.8±0.7 m 2 ml –1 of mitochondria, which is the same as for placental mammals, and the same pattern of similarity was seen for capillary densities...

... in the rat, averaging a 28 % increase in capillary-to-fibre ratio (C:F) but, as this was balanced by fibre hypertrophy across the whole muscle, there was no change in capillary density (CD). In contrast, the C:F was similar in both groups of hamsters, whereas CD rose by 33 % in line with fibre atrophy...

..., for vascular endothelial growth factor and for glycolytic enzymes, such as phosphofructokinase, together with mitochondrial and capillary densities, increased in a hypoxia-dependent manner. Functional analyses revealed positive effects on V̇ O2max (when measured at altitude) on maximal power output and on lean...
