However, remarkably high intra-regional gene flow was observed within the northwest region, perhaps a result of connectivity between populations of this region. In contrast, the central west and east coast region showed unexpected genetic homogeneity. Some frog species use roads as activity corridors,...

We used skeletochronology to estimate age structure of the Omei Wood Frog, Rana omeimontis, from southwestern China. Average age differed significantly between males and females. Age at sexual maturity in both males and females was 1 year. Longevity was 6 and 7 years for males and females, ...
pressure loss, reduce in noise increasing factors, and enhanced in heat dissipating properties by a method wherein a thin-walled cylindrical convection controlling tube is mounted on the frog-type heat sink covering the prescribed scope of the peripheral surface of a frog-type densely bundled pin ...
During takeoff and landing, birds bounce and grab with their legs and feet. In this paper,the lower limb structure of the bionic bird is designed with reference to the function of jumping and grasping, and the PID algorithm based on the development modul
