A Comparative Study Of Eucalanoid Copepods Residing In Different Oxygen Environments In The Eastern Tropical North Pacific: An Emphasis On Physiology And Biochemistry, Christine J. Cass

USF Tampa Graduate Theses and Dissertations

The eastern tropical north Pacific (ETNP) is characterized by one of the ocean's most severe midwater oxygen minimum zones (OMZs), where oxygen levels are often less than 5 µM. The copepod family Eucalanidae is a numerically abundant and diverse zooplankton group in the ETNP, and displays a wide range of vertical distributions related to environmental oxygen concentrations. The goal of this dissertation was to develop a better understanding of the ecology, physiology, and biochemistry of closely related copepod species (family Eucalanidae) that inhabit the ETNP OMZ system. This was accomplished through examining different parameters relating to (1) metabolic rates, (2) …
