...Gianluca De Rienzo; Francesco Aniello; Margherita Branno; Gaia Izzo; Sergio Minucci SUMMARY Frog relaxin ( fRLX ) belongs to the relaxin/insulin gene family present in the testis of Rana esculenta and is specifically expressed by Leydig cells. Since the expression of fRLX transcript changes during...

...Sandra Nauwelaerts; Peter Aerts SUMMARY Anurans use a saltatorial (jumping) mode of locomotion. A jumping cycle can be divided into four subphases: propulsion, flight, landing and recovery. We studied the landing phase during locomotion in Rana esculenta by measuring the ground reaction forces...

... Rana esculenta , applying digital particle image velocimetry (DPIV) to the frog's wake. The wake showed two vortex rings left behind by the two feet. The rings appeared to be elliptic in planform, urging for correction of the observed ring radii. The rings' long and short axes (average ratio 1.75:1...

.... In this study, we examine the use of the propulsive impulse as a covariate in the comparison of the kinematics of locomotion of a semi-aquatic frog Rana esculenta , across land and through water. We focused on the propulsive phase because it is functionally the most significant phase of the locomotor cycle...
