- Abstract
The ratios between individuals with different signs of motor asymmetry (right-pawed, left-pawed, and ambidextrous) were estimated in two urban populations of striped field mice. Right-pawed mice were prevailing in both populations. An increase in the stress of regulatory system (stress index) in mice from these populations was accompanied by a shift of the asymmetry profile towards a greater proportion of left-pawed mice. The ratio between the numbers of right-pawed and non-right-pawed animals varied with time with a period close to that of the population dynamics. Apparently, the changes in the asymmetry profiles reflected population rearrangement: dominance of animals with a specific set of physiological, ecological, and behavioral characteristics gave way to an increased proportion of animals with a different set of characteristics. Qualitative differences between right- and left-pawed animals are evidenced by the specific characteristics of behavior and humoral immunity found in animals differing in motor lateralization.
