We will consider the effects of diffusion and advection on principal  eigenvalue of elliptic operators. Various asymptotic behaviors of the principal eigenvalue, as diffusion or advection coefficients approach zero or infinity, are discussed. Motivations of these studies come from the speedup of front propagation and enhancing invasion of populations.
