Size and skeletal variation in male bank vole along an altitudinal gradient in western Norway

Size showed significant differences along the altitude gradient, and largest bank voles, Clethrionomys glareolus (Schreber, 1780), were found at an intermediate altitude were density also peaked. Individual skeletal variants did not show any uniform pattern of variation, but the overall estimate of divergence increased successively from sea level to treeline. Zbadano zmienność wielkości ciała i ubarwienia futerka oraz niemetrycznych cech szkieletu u samców Clethrionomys glareolus bytujących na różnych wysokościach n.p.m.
