In this thesis, I used a multi-level approach (whole animal, organ/tissue and cellular) to determine the functional relationships between maximum cardiac performance, heart morphology, and adrenergic capacity of the winter flounder (Pseudopleuronectes americanus) heart. Further, I studied the capacity of the flounder cardiovascular system to respond to two ecologically relevant environmental stressors: hypoxia and an acute temperature increase. In the first series of experiments, an in situ heart preparation was developed for this species, and in situ cardiac function and in vitro pressure-volume curves were determined. This research showed that maximum stroke volume per gram of ventricle is the highest reported for teleosts, and that this ...
