| Resumo: | Through six years Lepus flavigularis population density data were analyzed, at two localities southTehuantepec Isthmus, Oaxaca, Mexico. The fluctuation index (FI) was calculated for this lagomorph intwo localities. FI refers to ranges in fluctuations between maximum and minimum population levelsevaluated according to the average number of years required for the changes to take place. Density wasobtained by the fixed-width transect method. Lepus flavigularis exhibited low density values in bothpopulations. High FI values in Montecillo Santa Cruz indicate high amplitude of change in populationssize 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 changesover the same period of time. This probably because there is slight grazing and no prescribed burns. |
