Influence of Pacific Salmon on Stream Ecosystems
Dominic Chaloner

Research Interests:

There are two elements to my research: Pacific salmon and teaching. The focus of the salmon research is understanding the ecological consequences of migrating salmon, especially when they spawn in Southeast Alaska streams and Upper Great Lakes tributaries. Salmon spawners provide both a resource subsidy, through nutrients in their carcasses and eggs, but are also ecosystem engineers, through disturbance imparted during nest building. Most recently, I’ve been interested in salmon as biotransporters of contaminants, including persistent organic pollutants and heavy metals. Overall, this research has important implications for both fisheries and contaminant management. The focus of my teaching research is how intellectual virtues can be developed in science students through the courses they take as undergraduates. Intellectual virtues are character dispositions that contribute to human flourishing or well-being, and include such things as intellectual curiosity, humility, honesty, and open-mindedness. Arguably, the development of intellectual virtues results in not only well-educated and successful students but also productive and ethical scientists.
