Environmental Effects On Fish Escape Responses: Impact Of Flow On The Escape Performance Of The Hawaiian Stream Goby, Sicyopterus Stimpsoni, Kelly Diamond
All Theses
The ability of fish to escape from predators is a critical behavior for their survival. Experimental measurements of escape performance in fishes have typically been based on trials conducted in still water; however, such environmental conditions are rare in nature due to waves and currents that expose fishes to unsteady and/or directional flow. I examined the effects of water flow and predator attack direction on the escape behavior of fish, using juveniles of the amphidromous Hawaiian goby Sicyopterus stimpsoni as a model system. In nature, these fish must escape ambush predation by the Hawaiian sleeper, Eleotris sandwicensis, while exposed …
Evaluation Of Isokinetic Single-Leg Cycling As A Rehabilitation Exercise Following Anterior Cruciate Ligament Reconstruction Surgery, Jessica Myers
Evaluation Of Isokinetic Single-Leg Cycling As A Rehabilitation Exercise Following Anterior Cruciate Ligament Reconstruction Surgery, Jessica Myers
All Theses
The anterior cruciate ligament (ACL) is one of the most commonly injured ligaments, with over 250,000 injuries per year in the United States. Its primary function is to limit anterior tibial translation when the quadriceps muscle group contracts to extend the knee. Previous studies have found that ACL-deficient individuals avoid use of the quadriceps in the injured limb as a means of limiting anterior movement of the tibia in the absence of a functioning ACL. This altered gait pattern has been found to persist in the period following ACL reconstruction surgery, and inhibits the ability of patients to return to …
