How Some Arboreal Salamanders (Genus Aneides) Jump, Glide, And Generate Lift, Christian E. Brown
How Some Arboreal Salamanders (Genus Aneides) Jump, Glide, And Generate Lift, Christian E. Brown
USF Tampa Graduate Theses and Dissertations
The jumping and subsequent aerial behaviors of arboreal lungless salamanders (genus Aneides) had never been investigated or described. The aims of this research were to (1) compare jumping performance within the family Plethodontidae with a special focus on arboreal species from genus Aneides, (2) describe the biomechanics and kinematics of aerial behaviors after a jump or extended fall, and (3) model airflow over the morphology of the most aerially adept salamanders to investigate if they are capable of generating lift. First, I recorded salamanders jumping, locomoting vertically, dropping, and flying in a vertical wind tunnel. Then, I laser-scanned and reconstructed …

Operant (instrumental) conditioning is a laboratory model of voluntary behavior. In its simplest form, performing a particular response, such as a lever press, leads to delivery of a reinforcing outcome (e.g., a sucrose pellet). Operant behaviors can be associated with preceding stimuli (“habits”) or outcomes (“goal-directed actions”). A factor that influences performance of operant behaviors is the context in which they are learned. Contexts can be defined as background stimuli that are present during behavior. For example, eating dessert may occur in the context of a restaurant and the sated feeling of a finished meal. The context for eating dessert, …
