Dynamics of motor asymmetry profiles in striped field mouse (Apodemus agrarius pall.) populations

Dynamics of motor asymmetry profiles in striped field mouse (Apodemus agrarius pall.) populations 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Ecology Springer Journals

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.
