Seasonal and Latitudinal Variations in Circadian Rhythms of Red-Backed Vole
ABSTRACT. Circadian rhythms of two allopatric species, Clethrionomys gapperi and C. rutilus were studied near their common border at Heart Lake, Northwest Territories, Canada, in winter and spring of 1965-1966. Circadian rhythms of C. gapperi were also studied at Edmonton, Alberta, in the winter and...
