Technogenic morphological variation of the pygmy wood mouse (Sylvaemus uralensis pall.) in the Urals

Technogenic morphological variation of the pygmy wood mouse (Sylvaemus uralensis pall.) in the Urals Methods of geometric morphometrics have been used to compare the ranges and directions of geographic and technogenic forms of variation in the morphology of the mandible in Ural populations of pygmy wood mice (Sylvaemus uralensis Pall.) exposed to different types of pollutants (radionuclides, fluorides, and toxic petrochemical products). The range of variation in the mandible morphology consequent to chronic radiation exposure in the zone of the Eastern Ural Radioactive Trace is commensurate to the range of geographic variation of the species observed in the Middle and Southern Urals. Unspecific manifestations of variation have been revealed, which apparently result from exposure to technogenic pollutants of different origin. A probable contribution of technogenic variation to rapid morphogenetic rearrangements in populations is discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Ecology Springer Journals

Abstract

Methods of geometric morphometrics have been used to compare the ranges and directions of geographic and technogenic forms of variation in the morphology of the mandible in Ural populations of pygmy wood mice (Sylvaemus uralensis Pall.) exposed to different types of pollutants (radionuclides, fluorides, and toxic petrochemical products). The range of variation in the mandible morphology consequent to chronic radiation exposure in the zone of the Eastern Ural Radioactive Trace is commensurate to the range of geographic variation of the species observed in the Middle and Southern Urals. Unspecific manifestations of variation have been revealed, which apparently result from exposure to technogenic pollutants of different origin. A probable contribution of technogenic variation to rapid morphogenetic rearrangements in populations is discussed.
