“…However, this single ecoregional value drove significance of the regression; there was no correlation of testes size with seasonality when it was excluded ( p = 0.82). Greenbaum et al (2017, 2019) elaborated on the phylogenetic position of subspecies P. m. gambelli and P. m. sejugis (an island form), which are restricted to Southern and Baja California and occupy a physiographic context distinct from surrounding populations. The evolutionary distinctiveness of these subspecies, the unique Mediterranean climatic context they inhabit, or both, may contribute to the divergent relationship between testes size and seasonality that we found here.…”

Sex‐specific breeding phenologies in the North American deer mouse (Peromyscus maniculatus)

Effects of global climate change on population persistence are often mediated by life‐history traits of individuals, especially the timing of somatic growth, reproductive development, and reproduction itself. These traits can vary among age groups and between the sexes, a result of differential life‐history tactics and levels of lifetime reproductive investment. Unfortunately, the trait data necessary for revealing sex‐specific breeding behaviors and use of breeding cues over reasonably large geographic areas remain sparse for most taxa. In this study, we assembled and analyzed a new reproductive trait base for the North American deer mouse (Peromyscus maniculatus) from digitized natural history specimens and field censuses. We used the data to reconstruct sex‐specific breeding phenologies and their drivers within and among North American ecoregions. Male and female phenologies varied across the geographic range of this species, with discordance in timing and intensity being highest in regions of lower seasonality (and longer breeding seasons). Reliance on environmental variables as breeding cues also appeared to vary in a sex‐specific manner, being most similar for photoperiod and least similar for temperature (positive male response and negative female response); in addition, model validation indicated that phenological models generalized better for males than for females. Finally, our individual‐level trait data also show that male reproductive investment (quantified as relative testis size) varies across the vastly different abiotic and social (i.e., female breeding) contexts studied here. By harmonizing across a broad set of digital data resources, we demonstrate the potential to uncover drivers of phenological variation within species and inform global change predictions at multiple scales of biological organization.

“…Because the mitochondrial cytochrome-b (Cytb) gene is one of the most frequently amplified and sequenced mammalian markers and is useful for differentiating Peromyscus species (e. g., Zheng et al 2003;Dragoo et al 2006;Lucid and Cook 2007;Gering et al 2009;Kalkvik et al 2012;Greenbaum et al 2017), fragments of this gene were targeted for genetic assessments of specimens included in this study. For DNA extractions of frozen tissues, a 414 base pair (bp) fragment of Cytb was amplified using the primers MVZ04 and MVZ05 (Smith and Patton 1991) following Benedict et al (2019).…”

“…In addition to the remaining unconfirmed species records from 11 counties east of the fault zone, there are several specimens from localities from southern Texas (Figure 6) that may eventually be determined to be either P. leucopus or P. maniculatus. Thus, the Balcones fault zone may limit the distribution of P. maniculatus in Texas, as it does for many other taxa and that different climates, flora, and fauna across the four major regions in Texas (Trans-Pecos, Plains Country, East Texas, and Rio Grande Plains), and may additionally delimit the distribution of cryptic species within P. maniculatus (Bradley et al 2019;Greenbaum et al 2017Greenbaum et al , 2019. Future research with increased sampling is needed to determine the geographic range of "P. maniculatus" species in Texas.…”

Morphological differentiation of Peromyscus leucopus and P. maniculatus in East Texas

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.

Peromyscus sonoriensis is a widespread species ranging from southern Texas to the Yukon, from the Mississippi to the Pacific. Because of this extensive range, there are substantial differences in morphology due to variation in temperature, precipitation, and habitat. We used 2 data sets (n = 4,840 and n = 20,175) to study morphological differences of their crania and appendages. Consistent with Allen’s rule (shorter appendages with colder temperature), both data sets show a strong, positive, correlation between tail length and the average January temperature. However, there was an equally strong, but negative, correlation between tail length and average July temperature. We observed similar results for feet and crania. Ear length had a significant negative correlation with July average temperature but no correlation with January average temperature. When we controlled for temperature, cranial and appendage length increased with latitude, which was opposite of what we expected. Furthermore, longitude had a strong impact as mice trapped further west had longer appendages. When divided into habitats, forest deer mice are more likely than prairie or desert deer mice to demonstrate morphological responses to differences in climate, location, and year trapped. Our results show that P. sonoriensis exhibit notable morphological variation linked to location, habitat, and climate.
