Abstract

We document the isolation and characterization of 14 tetranucleotide microsatellite DNA markers in Preble's meadow jumping mouse (Zapus hudsonius preblei). The identified markers displayed moderate levels of allelic diversity (averaging 4.9 alleles per locus) and heterozygosity (averaging 55.1%). Genotypic and allelic frequencies in a collection of 30 individuals conformed to Hardy-Weinberg equilibrium expectations and indicated no linkage disequilibrium. High levels of cross-amplification (95% overall) among neighbouring subspecies and two congeners (Zapus princeps and Zapus trinotatus) were observed. Multilocus genotypes resulting from these markers appear to provide ample genetic diversity for studies assessing individual- and population-level ecological interactions within Z. h. preblei and evolutionary relationships among neighbouring subspecies (Z. h. campestris, Z. h. intermedius, Z. h. pallidus and Z. h. luteus).
