The allometry of predator-prey relationships

• Francis Juanes

Abstract
My overall goal is to infer ecological generalities from a quantitative description of predator-size prey-size relationships. New analytical and statistical tools will allow me to describe the edges of these data scatters which will provide information about the ontogeny of predation, the onset of prey shifts and the constraints of relative prey size. I will focus on piscivouous fishes because they are at the top of many aquatic trophic webs, show distinct ontogenic diet shifts and exhibit much variationin predator-prey relationships.
