.... To further test hypotheses about traits that represent specializations for scratch-digging, we quantified muscle architectural properties and myosin expression in the forelimb of the groundhog ( Marmota monax ), a digger that constructs semi-complex burrows. Architectural properties measured were muscle...

...Justin F. Shaffer; William M. Kier SUMMARY The speed of muscle contraction is largely controlled at the sarcomere level by the ATPase activity of the motor protein myosin. Differences in amino acid sequence in catalytically important regions of myosin yield different myosin isoforms with varying...
