Within a theme of adaptations to global change, Hobson’s research is at the interface between applied animal ecology/conservation and Biogeochemistry with particular emphasis on the development and use of naturally occurring stable isotopes and other intrinsic markers to answer otherwise intractable questions. This approach has been applied to a broad range of research questions ranging from the ecology of individuals to communities at local to continental scales. Hobson’s most recent emphasis has been on addressing nutrient allocation strategies in birds and full life-cycle conservation of migratory birds and insects through the development and use of isoscapes. This work seeks to examine how anthropogenic changes are influencing migratory organisms throughout their annual cycles and to identify best conservation practices.
