Temporal segregation in co-existing Acomys species:the possible role of nest site

Research output: Contribution to journalArticlepeer-review


The co-existence of two species of spiny mouse of the genus Acomys is possible due to temporal segregation. While the common spiny mouse A. cahirinus is nocturnal, the golden spiny mouse A. russatus is diurnal when occurring with the former. An attempt was made to investigate the role of nest site as an environmental resource for competition between these two species. Nine heterospecific pairs of mice of both the same or opposite sexes were tested using an observation pen with two nesting places attached to each side. Each pair tested was observed in the pen over a period of 48h. In eight out of the nine different pairs, A. cahirinus occupied the original nest site of A. russatus. The replacement was found to be not random. The results of this study show that A. cahirinus selects a preferred nest site and its vacated nest sites can be utilized by A. russatus.
