As part of a monitoring program used to evaluate the status of the zacatuche rabbit's populations within this PNA, we estimated its distribution by using direct (sightings) and indirect methods (latrines) during visits performed to all the available habitats. Additionally, we estimated the annual density of the zacatuche rabbit using a line transect method, sampling eight, one-kilometer-long transects monthly during one year. Based on 101 latrine records and 48 sightings, a distribution map was prepared for the region using the convex polygon method in ArcView. Most of this distribution (166.43 km2) represents an area that had not been previously reported in the literature for the zacatuche rabbit. Using the half-normal model that best fit the data, we estimated a density of 4.2 rabbits/ha. Our results suggest that the Corredor Biológico Chichinautzin meets the criteria necessary to be cataloged as a core distribution area for the zacatuche rabbit. Therefore, we suggest that both management and conservation of this habitat within the PNA should be made a priority.]]></p></abstract>

Como parte de un programa de monitoreo para evaluar el estado de las poblaciones del conejo zacatuche en esta ANP, estimamos su distribución utilizando métodos directos (avistamientos) e indirectos (letrinas) durante visitas a todos los hábitats disponibles. Además, se estimó su densidad anual utilizando el método de transectos lineales, muestreando cada mes ocho transectos de un km de largo durante un año. Con base en los registros de 101 letrinas y 48 avistamientos, se elaboró un mapa de distribución para la región mediante el método del polígono convexo en ArcView. La mayor parte de esta distribución (166,43 km2) representa un área que no habían sido previamente reportada en la literatura para el zacatuche. Usando el modelo half-normal que fue el mejor que se ajustó a los datos, se estimó una densidad de 4.2 conejos/ha. Nuestros resultados sugieren que el Corredor Biológico Chichinautzin cumple con los criterios necesarios para ser catalogado como un área núcleo de distribución para el zacatuche. Por lo tanto, sugerimos que el manejo y la conservación de este hábitat en el ANP deben ser una prioridad.]]></p></abstract>
