Summary of mechanical parameters for Rana esculenta and Rana temporaria
| R. esculenta | R. temporaria | |
|---|---|---|
| T0 (kPa) | 160 ± 4 | 256 ± 17 |
| Chs at T0 (nm MPa−1) | 24.1 ± 0.3 | 19.7 ± 0.9 |
| Chs in rigor (nm MPa−1) | 15.4 ± 0.4 | |
| Cf (nm MPa−1) | 13.0 ± 0.7 | |
| 1/βe (nm MPa−1) | 11.1 ± 0.8 | 6.7 ± 1.1 |
| 1/e (nm MPa−1) | 2.4 ± 0.8 | |
| Ccb (nm pN−1) | 0.37 ± 0.12 | |
| ε (pN nm−1) | 2.7 ± 0.9 | |
| Fraction attached | 0.22 ± 0.06 | 0.36 ± 0.10 |
Data for T0 and Chs at T0 are mean ± SEM of the values reported in the literature. R. esculenta: (Piazzesi et al. 2002a, 2003; Decostre et al. 2005; Brunello et al. 2009; Fusi et al. 2010). R. temporaria: (Piazzesi et al. 2002b, 2007; Reconditi et al. 2004; Brunello et al. 2006; Linari et al. 2009). Chs in rigor is the same in R. esculenta (Fusi et al. 2010) as in R. temporaria (Piazzesi et al. 2007). The value of Cf is the mean of X-ray (this work) and mechanical (Fusi et al. 2014) estimates (see text for details).
