Regional and local patterns of genetic variation and structure in yellow‐necked mice ‐ the roles of geographic distance, population abundance, and winter severity
Abstract The goal of this study, conducted in seven large woodlands and three areas with small woodlots in northeastern Poland in 2004–2008, was to infer genetic structure in yellow‐necked mouse Apodemus flavicollis population and to evaluate the roles of environmental and population ecology variabl...
