Dominic is an Assistant Research Professor associated with two projects: 1) a recently USDA-funded study of the interactions between salmon-derived nutrients from spawning Pacific salmon (Oncorhynchus spp.) and land management in southeastern Alaskan watersheds, and 2) a NOAA-funded project examining the ecological impacts on freshwater ecosystems of ionic liquids, a novel group of ‘green’ solvents. Specifically, Dominic is interested in both ecosystem-level (e.g., production) and community-level (e.g., diversity) responses of freshwater ecosystems to perturbations associated with salmon spawners and pollution, and if and how this information can be incorporated into resource management plans. Dominic is also interested in how ecosystem and community responses might be mediated and modulated by microbial decomposers, such as water molds (Saprolegnia, a mycelial heterotroph), and invertebrate consumers, especially chironomid midges (Diptera: Chironomidae), one of the more important and widely distributed families of aquatic insects. Both groups of aquatic organisms are important colonists of organic material and food source for higher trophic levels, and therefore play a critical role in mediating the effects of salmon spawners and pollution on the rest of the stream food web.
