| description | Through six years Lepus flavigularis population density data were analyzed, at two localities south Tehuantepec Isthmus, Oaxaca, Mexico. The fluctuation index (FI) was calculated for this lagomorph in two localities. FI refers to ranges in fluctuations between maximum and minimum population levels evaluated according to the average number of years required for the changes to take place. Density was obtained by the fixed-width transect method. Lepus flavigularis exhibited low density values in both populations. High FI values in Montecillo Santa Cruz indicate high amplitude of change in population’s size in a short period of time. This probably caused by extensive grazing and prescribed burnings. In San Francisco del Mar Viejo L. flavigularis exhibited low FI values, indicating low population changes over the same period of time. This probably because there is slight grazing and no prescribed burns. |

Se analizaron datos sobre densidad poblacional de la liebre de Tehuantepec, Lepus flavigularis durante seis años de monitoreo en las poblaciones de Montecillo Santa Cruz y San Francisco del Mar Viejo, al sur del Istmo de Tehuantepec, Oaxaca, México. Se calculó el índice de fluctuación poblacional (IF) para esta especie de lagomorfo en las dos localidades. Los intervalos en fluctuación entre niveles poblacionales máximos y mínimos fueron evaluados de acuerdo al número promedio de años requeridos para que los cambios ocurran. Se llevó a cabo el método de transecto de ancho fijo para la obtención de valores de densidad. La liebre de Tehuantepec presenta en general, valores en densidad bajos en ambas poblaciones de estudio, con IF altos en Montecillo Santa Cruz, lo que indica que presenta una gran amplitud de cambios en su tamaño poblacional en periodos de tiempo cortos, debido probablemente a las prácticas de uso de suelo de la zona, mismas que incluyen una intensa ganadería extensiva y la aplicación de quemas controladas. En San Francisco del Mar Viejo, zona con menor intensidad de pastoreo y sin quemas, la liebre de Tehuantepec presentó valores de IF bajos, por lo que es probable que en esta población la especie se mantenga más estable a lo largo del tiempo.
