In this study, we aimed to investigate the effect of aestivation on iliofibularis and sartorius muscle morphology and contractile function of C. alboguttata over a longer, more ecologically relevant time-frame of 9 months. We found that whole muscle mass...

In addition to being greater in wet mass and in cross-sectional area in the males, our data show that the dimorphic muscles...
