We analyze traveling front solutions for a class of reaction-transport Lattice Models (LMs) in order to claim their interest on the description of biological invasions. As lattice models are spatially discrete models, we address here the problem of i

The front dynamics in reaction–diffusion equations with a piecewise linear reaction term is studied. A transition from pushed-to-pulled fronts when they propagate into the unstable state is found using a variational principle. This transition occur

The speed of pulled fronts for parabolic fractional-reaction-dispersal equations is derived and analyzed. From the continuous-time random walk theory we derive these equations by considering long-tailed distributions for waiting times and dispersal d

On the basis of the Cook model, we propose a delayed-growth reaction–diffusion model with an age-dependent disperser–nondisperser transition. We compare the speed of migration fronts between our model and the hyperbolic generalization of the Cook

The effect of the delay time on the speed of wave fronts for interacting–diffusing models is studied analytically and numerically, both for predator–prey and competition models. It is shown that the interaction parameters may be evaluated from th

From the continuous-time random walk scheme and assuming a L\'evy waiting time distribution typical of subdiffusive transport processes, we study a hyperbolic reaction-diffusion equation involving time fractional derivatives. The linear speed selecti

Recently, it has been shown that the speed of virus infections can be explained by time-delayed reaction-diffusion [J. Fort and V. Mendez, Phys. Rev. Lett. 89, 178101 (2002)], but no analytical solutions were found. Here we derive formulas for the fr
