Resumen:
Wave propagation can be clearly discerned in data collected on mouse populations in the Cibola
National Forest (New Mexico, USA) related to seasonal changes. During an exploration of the
construction of a methodology for investigations of the spread of the Hantavirus epidemic in mice
we have built a system of interacting reaction diffusion equations of the FisherKolmogorov
PetrovskiiPiskunov type. Although that approach has met with clear success recently in explaining
Hantavirus refugia and other spatiotemporal correlations, we have discovered that certain observed
features of the wave propagation observed in the data we mention are impossible to explain unless
modifications are made. However, we have found that it is possible to provide a tentative explanation/
description of the observations on the basis of an assumed Allee effect proposed to exist in the
dynamics. Such incorporation of the Allee effect has been found useful in several of our recent
investigations both of population dynamics and pattern formation and appears to be natural to theobserved system. We report on our investigation of the observations with our extended theor
