I am an ecophysiologist and I investigate how consumers adapt to their nutritional landscape, especially in the face of global environmental change. I have primarily examined how omega-3 polyunsaturated fatty acids (n-3 PUFAs) move through and are modified by consumers within food webs. While aquatic primary producers are often rich in n-3 long-chain (LC) PUFAs, these compounds are extremely scarce at the base of terrestrial ecosystems. During my PhD, I showed that aquatic insects are much richer in n-3 LCPUFAs than are terrestrial insects and that aquatic insects subsidize riparian birds with these compounds. I also demonstrated that n-3 LCPUFAs improve performance in two species of riparian birds and used field 13C dosing to reveal that their nestlings are inefficient at LCPUFA synthesis. These findings have revealed the unique role that aquatic ecosystems play as sources of critical nutrients for both aquatic and terrestrial consumers and highlight the importance of understanding how processes like climate and land use change are altering the quality, quantity, and phenology of aquatic to terrestrial subsidies. In my current postdoc, I am studying the behavioral and metabolic adaptations that marine fish have used to colonize freshwaters.
