Contemporary ecosystems lack many extinct large-bodied mammals, motivating mechanistic allometric models of megafaunal persistence. Large-bodied trophic interactions can become dynamically infeasible depending on predator-prey mass relationships, predation intensity, resource productivity, and human harvest. Mammalian megafauna are described as intrinsically fragile because they have low densities and slow reproduction.
