Abstract

We studied a community of small mammals which included five species. Our aim was to examine the niche partitioning in space and time between the species. A secondary aim was to estimate abundance and other demographic parameters. The project was carried out from December 2013 to December 2014 on Crete. The site is a Shrub-land (Phrygana) with light soil coverage over rocky ground and light human disturbance. It is located on a hill at 280 m. above sea level south of the Heraklion Industrial area. Dominant species of vegetation: Calicotome villosa, Sarcopoterium spinosum. Trapping experiments using mark-recapture techniques were conducted for a total of 4600 trap nights. One hundred Sherman live traps were set out per sampling night in a 2 hectare area. The MARK software as well as the methods of Petersen and Schnabel were used to estimate animal abundance. Our results suggests there is competition between Apodemus sylvaticus and each of Mus domesticus and Acomys cahirinus, but not between the two latter. We were unable to safely estimate abundance and other demographic parameters. We propose the use of estimations as population abundance indices. The environmental factors we examined, explained nearly 50% of the catchability for the species Mus domesticus, Acomys cahirinus and Apodemus sylvaticus.
