Sexual size dimorphism in free-living populations of Mus mucsulus: Are male house mice bigger?
Original language description
We studied sexual size dimorphism (SSD) in captive house mice derived from free-living commensal (inhabitants of buildings and stores) and non-commensal (field and/or semidesert dwellers) populations. While females of commensal populations and most strains of laboratory mice are more or less tolerant to each other, females from non-commensal populations are as highly aggressive as their male conspecifics. As body size considerably contributes to fighting success, we addressed the question whether sexualsize dimorphism in commensal mice, with larger males, can be attributed to the switch to the commensal way of life. For this purpose, we performed a laboratory common garden experiment in which non-commensal populations of Mus musculus domesticus from Jordan and SW Iran were compared with Greek commensal mice belonging to the same subspecies. M. m. musculus and natural hybrids of these subspecies from the Czech Republic were also included. Growth was recorded for 102 litters and 592 juv
