Aquatic turning performance of painted turtles (Chrysemys picta) and functional consequences of a rigid body design by Rivera, Gabriel, Rivera, Angela R V, Dougherty, Erin E, Blob, Richard W

“…The ability to capture prey and avoid predation in aquatic habitats depends strongly on the ability to perform unsteady maneuvers (e.g. turns), which itself…”

Hydrodynamic stability of the painted turtle (Chrysemys picta): effects of four-limbed rowing versus forelimb flapping in rigid-bodied tetrapods by Rivera, Gabriel, Rivera, Angela R V, Blob, Richard W

“…Hydrodynamic stability is the ability to resist recoil motions of the body produced by destabilizing forces. Previous studies have suggested that recoil…”

Forelimb kinematics during swimming in the pig-nosed turtle, Carettochelys insculpta, compared with other turtle taxa: rowing versus flapping, convergence versus intermediacy by Rivera, Angela R V, Rivera, Gabriel, Blob, Richard W

“…Animals that swim using appendages do so by way of rowing and/or flapping motions. Often considered discrete categories, rowing and flapping are more…”

Forelimb kinematics and motor patterns of swimming loggerhead sea turtles (Caretta caretta): are motor patterns conserved in the evolution of new locomotor strategies? by Rivera, Angela R V, Wyneken, Jeanette, Blob, Richard W

“…Novel functions in animals may evolve through changes in morphology, muscle activity or a combination of both. The idea that new functions or behavior can…”
