The Macedonian mouse (Mus macedonicus) is a species of rodent in the family Muridae and order Rodentia. This rodent lives in the area from eastern Georgia and western Bulgaria to Israel.[2] It is considered part of a Paleoarctic group along with three other types of rodents: M. musculus, M. spicilegus, and M. spretus.[3]

Description[edit]

The Mus macedonicus is a small rodent (15 g).[4] It has very different fur color based upon location. In a study of numerous specimens in Turkey, the Mus macedonicus was found to have back colors ranging from dark brown to pale light brown to dark-reddish brown.[5] There is a distinct line of demarcation along the flanks that separates top and bottom coloration.[5] The bottom coloration ranged from whitish grey, pure white, yellowish white, and reddish white.[5] The ears have tiny white hairs.[5] This rodent has a tail that is dark brown on top and lighter on bottom. [5] The bottoms of the Mus macedonicus' feet are bare while the tops of their feet have white hairs.[5] Mus macedonicus are nocturnal.[4]

Morphology[edit]

The sutura squamalis has distinction from other species because it is smoothed or protrudes slightly forward.[5] The upper portion of the zygomatic arch is also more narrow than the lower portion.[5] Mus macedonicus found in Israel are smaller than their Northern counterparts.[2]

Physiology[edit]

Body mass of Mus macedonicus exposed to short photoperiods increased - essentially they got bigger to stay warmer when it is cold.[4] The short photoperiods also increased their resistance to cold while long photoperiods increased their ability to manage higher temperatures.[4] Food consumption and waste production are lower in the mice that have longer photoperiods.[4] These physiological changes allow Mus macedonicus to be well adapted to the changes that occur in the Mediterranean on a seasonal basis.[4] This mouse also shows a genetic tendency for glial fibrilary acidic protein in their lens epithelial cells.[6] This is a new marker of polymorphism in the Mus Genus.[6]
