Phenotypic diversity and population dynamics: another look (with particular reference to the common shrew Sorex araneus )

Abstract

Authors studied temporal changes in the level of phenotypic diversity, measured by the total phenotypic variance for several characters of skull morphology, in two populations of the common shrew Sorex araneus Linnaeus, 1758. Authors compared a population from central Siberia having a high-amplitude four-year cycle with a population from southern Finland having noncyclic dynamics.
