WILD 3580 1st Edition Lecture 26Outline of Last Lecture I. Sex DeterminationII. Parthenogenesis III. Thermoregulation Outline of Current Lecture I. Behavioral ThermoregulationII. LocomotionCurrent LectureI. Behavioral Thermoregulation- Examples:- Digestion- Reproductive status - Health status- behavioral fever to decrease infection and increase immune response II. Locomotion - Turtles, lizards, and crocodilians o Quadrupedal locomotion- moving on four legs Lizards and crocs: sprawling limb posture - Advantages: stable, wide base- Disadvantages: not fast, not suitable for heavy body weights o Bipedal locomotion- hind limbs Some lizards (ex. Basalisk lizards) o Turtle locomotion is limited by fused vertebrae and carapace space Spine does not move- Snakes o Types of movements 1. Rectilinear/caterpillar- straight forward movementThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute. Sequential movement of scales moving from the underside Most snakes 2. Serpentine/ lateral undulation: curves of the snake are pushing of the ground surface using the movement of the body Needs high friction surface Also used for swimming 3. Concertina movement: tail pushes front of the body forward, then pushes head to push tail forward Used in areas of low friction surfaces and small spaces4. Sidewinding movement: head and tail pick up the rest of the body; crabby like locomotion In very unstable substrate like sand Fairly
