Michael Power

• Ecology and Environmental Biology

Research completed has applied SIA to determine trophic differentiation in Arctic ciscoes (Muir et al. 2014), Arctic charr (Eloranta et al. 2013) lake whitefish (Fagan et al. 2012) and Atlantic salmon (Dixon et al., 2012), measure critical changes in fish habitat use by resident stocks (Murdoch and Power 2013, Sinnatamby et al. 2013), determine long-term fluctuations in Atlantic salmon trophic positioning (Sinnatamby et al. 2009, Am. Fish. Symposium 69:447) and examined effects of water level fluctuations on lake resident fishes (Eloranta et al. 2016, Kelly et al. 2015). Power also has extensive experience in fish community (Attrill & Power 2002, Nature 417:275) and isotope analysis of estuarine and marine ecosystems (Sasko et al. 2016; Giraldo et al. 2016). Finally Power has been refines and applied otolith isotope methods useful for differentiating habitat use in fishes (e.g., Kelly et al 2015, Minke-Martin et al. 2015, Power et al. 2012).
