“…Although several studies have shown that P. leucopus and P. maniculatus may exhibit significant differences in external traits, measurement ranges often overlap and classification analyses based on external morphology analyses tend to perform moderately or poorly (Rich et al 1996;Kamler et al 1998;Lindquist et al 2003). Indeed, it often appears that reliable and accurate identification of either species requires detailed cranial measurements (Rich et al 1996), or molecular methods such as salivary amylase phenotyping (Aquadro and Patton 1980), and amplification of genetic markers (Tessier et al 2004;Ridenhour and Cramer 2015;Seifert et al 2016). The similarities in morphology, ecology, and life history traits suggest that potential hybridization between both species is possible.…”

“…A method commonly used in recent studies to discriminate between the two Peromyscus species relies on amplification of the mitochondrial COIII marker (e.g., Tessier et al 2004;Ridenhour and Cramer 2015). As a mitochondrial marker, COIII is often employed in phylogenetic studies investigating evolutionary relationships among mammalian species.…”

In some parts of southern Quebec, two closely related rodent species - the white-footed mouse (Peromyscus leucopus) and the deer mouse (Peromyscus maniculatus) - have recently come in contact because of climate-driven changes in the distribution of the former. Both species share similar morphology, ecology, and life history traits, which suggests that natural hybridization may be possible. Hybridization among these two species can have important implications on the ecological roles these rodents play in disease transmission, yet few researchers have attempted to examine this phenomenon and results from previous hybridization experiments have remained inconclusive and conflicting. In this study, we attempt to investigate the occurrence of hybridization among white-footed mice and deer mice in southern Quebec by genotyping wild caught specimens with selectively neutral, polymorphic microsatellite markers. Our analyses suggest that hybridization may be occurring at extremely low frequency between both species in our study area. The presence of such hybridization events, even at low frequencies, may have implications on disease transmission risk in the region and further detailed studies are necessary.
