Field identification of the White-footed Mouse (Peromyscus leucopus noveboracensis) and Long-tailed Deer Mouse (Peromyscus maniculatus gracilis) is difficult because of their similar external morphology. Peromyscus were sampled by live-trapping during a five-year period (1992-1996) at the Arnot Teaching and Research Forest, Van Etten, New York and identified to species by electrophoresis of their salivary amylase. No electromorphs were shared between P. leucopus and P. maniculatus, thus permitting unambiguous species identification of individuals. Means and ranges of four external measurements (ear, head-body, hind-foot, and tail) and tail to head-body ratio were determined for amylase-genotyped live mice. Although some body measurements did differ on average between the two species (ear, head-body, and tail for adults; hind-foot and tail for juveniles), the ranges of these overlap considerably. When the four external measurements (excluding the tail to head-body ratio) were used to construct two discriminant-function equations, they yielded correct identification of 80% of the adult P. l. noveboracensis and P. m. gracilis assessed excluding juveniles, and 71% of adult and juvenile mice combined. The function reported here allows partial field identification, but genetic analysis remains the only reliable field method for differentiation between live P. l. noveboracensis and P. m. gracilis. Includes erratum for a figure in this article.

The white-footed deer mouse (Peromyscus leucopus) and the North American deer mouse (P. maniculatus) are widely distributed throughout North America, often with overlapping distributions. These species are believed to be sympatric east of the Balcones fault zone in Texas, but records from natural history collections indicate that P. maniculatus is not common from this region. Given that these two species are notoriously difficult to differentiate morphologically, it is possible that specimens have been incorrectly identified and that P. maniculatus may be rare or not present in East Texas. This study aims to determine if P. leucopus and P. maniculatus can be differentiated morphologically east of the Balcones fault zone in Texas. Cranial and external characters from genetically identified specimens representing each species were analyzed using traditional and geometric morphometric methods. Morphological analyses revealed that genetically identified specimens of P. leucopus and P. maniculatus from east of the Balcones fault zone could be differentiated using a suite of morphological characters. Many of the specimens of P. leucopus used in this study were originally misidentified, suggesting that P. maniculatus is rare in East Texas.

Species Specific

This study explores foraging choices made by seed predators (white-footed mouse, Peromyscus leucopus noveboracensis (Fischer, 1829), and woodland deer mouse, Peromyscus maniculatus gracilis (LeConte, 1855)) presented with seeds of two dominant tree species (sugar maple, Acer saccharum Marsh., and red maple, Acer rubrum L.). I hypothesized that both species would prefer A. saccharum seeds, as they are larger and ostensibly contain more energy. Although P. l. noveboracensis consumed more seed than P. m. gracilis, there was also a species-specific difference in preference. Peromyscus maniculatus gracilis clearly preferred A. rubrum over A. saccharum, whereas preferences of P. l. noveboracensis were less specific. Peromyscus leucopus noveboracensis, being a habitat generalist, may demonstrate higher plasticity in response to different food types. Peromyscus maniculatus gracilis may prefer A. rubrum because of differences in nutrition, handling costs, or germination schedules, although this was not explicitly tested. This species-specific difference in preference indicates the common assumption that Peromyscus species are ecologically similar should be made with caution.

Morphometric measurements or biochemical methods are often required to differentiate deer mice, Peromyscus maniculatus (Wagner, 1845), from white-footed mice, Peromyscus leucopus (Rafinesque, 1818), particularly when they are found in sympatry. However, these approaches cannot easily be applied to juveniles, or to degraded or ancient museum specimens. In this paper, we propose a rapid and non-invasive molecular approach to discriminate these cryptic species from one another. This technique relies on species-specific primers designed in the COIII mitochondrial region to amplify fragments of different lengths in each species. The method developed proved useful for the identification of ethanol-preserved, frozen, degraded, or dry museum specimens.
