| Summary: | In this article we present some aspects related to the population ecology of Mus musculus at the beginning and throughout the course of the dry season in the Lachay lomas. Population abundance in three zones with different altitudes decreased drastically during the dry season. Sex proportions showed that the number of males was always higher than the number of females. Home range was not statistically different between the three analyzed areas. Our results suggest that the presence and/or abundance of plants may be one of the most important in regulating the population this species. In addition our study suggests the hypothesis that females of Mus musculus are more sensitive tha males to the adverse climatic conditions in the Lachay National Reserve during dry season. |
