Mary Alice McWhinnie also conducted a significant amount of research into the field of Crustecdysone Mediated Changes in Crayfish. One of these noted changes is that of molting. McWhinnie noted that the molting process of crayfish is needed for growth in the organism, and results in lower levels of organic material present during the stages of premolt. She also was careful to discern that premolt crayfish regularly have higher levels of amino acids in their various tissues than they do during the intermolt stage.

McWhinnie also focused a lot of her research on the respiration processes of the antarctic copepod. Also known as, Rhincalanus gigas. During an austral winter, McWhinnie measured the procurement of oxygen and the production of carbon dioxide from the R. gigas. With the discovery that oxygen levels were lower than those from lower latitude specimens, Mary Alice McWhinnie began to believe that new type of metabolic adaptation had been developed in order to effectively create two periods of reproduction for R. gigas. http://onlinelibrary.wiley.com/doi/10.4319/lo.1976.21.5.0763/full
