Philosophers and laymen alike have often used morality to invite misconceptions of human life into ethics, and also of ethics into human life. The Kant/Williams discourse provides a rich backdrop on which to consider these misconceptions. But the misconceptionsof morality involved are just as numerous and just as serious. One thing that the Kant/Williams discourse shows is this: that ethics can be neither contained by nor cultivated without morality. Though much of Williams’ critique of Kantian morality is quite astute, thephilosophical and ethical wisdoms of morality abound in spite of these. Morality understands the fundamental condition of moral loss, and the sometimes irreducible quandaries that this condition places human beings in. It understands the nature of the moral law, and theintricacies that the levels of letter and spirit invite into human life. Perhaps more importantly, it understands the uncompromising relationship between moral loss and moral law, and how the human navigation of this relationship leads into the ethical realm via giving rise to ethical conviction. Finally, for all of its pressures, morality abounds in valuable wisdoms for the one discovering that the human soul occupies a place of ethical significance in the world. It is responsible for pointing out, grounding and providing a framework for some of the most fundamental truths about the world and human beings; and these are essential to any viable ethical theory and sensible conception of human life.

Fluctuations of food availability, habitat quality, and environmental conditions throughout the year have been implicated in the breeding success and survival of migratory birds. Levels of circulating corticosterone, the hormone involved in energy balance and the stress response in birds, are also affected by fluctuations in these variables, and also play a role in self-maintenance and survival. In addition to changes in behaviors and resource allocation, the metabolic effects of corticosterone increase the amount of free radicals in the body, which can cause oxidative stress and damage lipids and DNA. In this thesis, I assessed if diet and physiology during the breeding and non-breeding seasons contributed to the reproductive success, survival, and oxidative stress of a long-lived migratory seabird, Leach’s storm-petrel (Oceanodroma leucorhoa). I tested the hypotheses that 1.) diet and physiology throughout the breeding and non-breeding seasons predict reproductive effort; and 2.) corticosterone affects telomere length, a measure of oxidative damage. Through analyses of stable isotopes, corticosterone, and antioxidant capacity, I found that although there was variation in these measures of diet and physiology within the population, none of these factors during the breeding or non-breeding seasons correlated with reproductive effort or success. I also found that feather and plasma corticosterone did not predict telomere length. The life history strategies of Leach’s storm-petrels appear to be complex, and many factors likely contribute to self-maintenance and the decision to breed. Long-term monitoring of these variables may help identify relationships between trends in oceanographic variables during both the breeding and non-breeding seasons with reproductive effort and success, and survival.
