    "abstract": "We analyze data from a long term field project in New Mexico, consisting of\nrepeated sessions of mark-recaptures of Peromyscus maniculatus (Rodentia:\nMuridae), the host and reservoir of Sin Nombre Virus (Bunyaviridae:\nHantavirus). The displacements of the recaptured animals provide a means to\nstudy their movement from a statistical point of view. We extract two\nparameters from the data with the help of a simple model: the diffusion\nconstant of the rodents, and the size of their home range. The short time\nbehavior shows the motion to be approximately diffusive and the diffusion\nconstant to be 470+/-50m^2/day. The long time behavior provides an estimation\nof the diameter of the rodent home ranges, with an average value of 100+/-25m.\nAs in previous investigations directed at Zygodontomys brevicauda observations\nin Panama, we use a box model for home range estimation. We also use a harmonic\nmodel in the present investigation to study the sensitivity of the conclusions\nto the model used and find that both models lead to similar estimates.",
