Experimental evolutionary studies are excellent approaches to study the coadaptation of the musculoskeletal with locomotor behavior in real time. My dissertation examines mice from 4 replicate High Runner (HR) lines bred for voluntary wheel running as young adults and their 4 no…

The majority of previous research investigating the role of vision in controlling adaptive gait has predominantly focused on over-ground walking or obstacle negotiation. Thus there is a paucity of literature investigating visuomotor control of step descent. This thesis addressed…
Birds are a diverse group of vertebrates, with over 10,000 extant species. Diversification into volant, aquatic and terrestrial environmental niches has precipitated a remarkable morphological diversity between species. Birds have a unique respiratory system consisting of a rigi…
Previous attempts to understand the factors affecting the energetic cost of locomotion have found a direct link between the energetic cost and the mechanical work done during periods when the limb is in contact with the ground. However, when the limb is not in contact with the g…
An illustrated ethogram describes the behavioral ecology and skin components of Abdopus aculeatus studied on Sulawesi, Indonesia and Queensland, Australia. These octopuses aggregated on intertidal reef flats and foraged for crustaceans during diurnal mid and low tides. Mating by…
Biological locomotion control systems provide an ideal research platform for the development of control theories for robotic locomotion. Two properties of significant practical value, adaptability and energy efficiency, are observed in biological systems. Systems-level modeling …
Autotomy is the shedding of a body part as a means of secondary defense against a predator that has already made contact with the organism. This defense mechanism has been widely studied in a few model taxa, specifically lizards, a few groups of arthropods, and some echinoderms.…
