“…The same is true for variation among beach mice. For example, while Osgood (1909) held an adaptationist interpretation of racial differentiation, he provided no evidence to support his position. Sumner, who initially held a neo-Lamarckian belief, challenged Osgood's view, suggesting that the phenotypic differences were environmentally induced (Provine 1983).…”

Adaptive basis of geographic variation: genetic, phenotypic and environmental differences among beach mouse populations

et al. 2009

A major goal in evolutionary biology is to understand how and why populations differentiate, both genetically and phenotypically, as they invade a novel habitat. A classical example of adaptation is the pale colour of beach mice, relative to their dark mainland ancestors, which colonized the isolated sandy dunes and barrier islands on Florida's Gulf Coast. However, much less is known about differentiation among the Gulf Coast beach mice, which comprise five subspecies linearly arrayed on Florida's shoreline. Here, we test the role of selection in maintaining variation among these beach mouse subspecies at multiple levels-phenotype, genotype and the environments they inhabit. While all beach subspecies have light pelage, they differ significantly in colour pattern. These subspecies are also genetically distinct: pair-wise F ST -values range from 0.23 to 0.63 and levels of gene flow are low. However, we did not find a correlation between phenotypic and genetic distance. Instead, we find a significant association between the average 'lightness' of each subspecies and the brightness of the substrate it inhabits: the two most genetically divergent subspecies occupy the most similar habitats and have converged on phenotype, whereas the most genetically similar subspecies occupy the most different environments and have divergent phenotypes. Moreover, allelic variation at the pigmentation gene, Mc1r, is statistically correlated with these colour differences but not with variation at other genetic loci. Together, these results suggest that natural selection for camouflage-via changes in Mc1r allele frequency-contributes to pigment differentiation among beach mouse subspecies.

“…Sumner 1926;Haldane 1948;Hoekstra et al 2006;Mullen & Hoekstra 2008). However, there are also discrete colour pattern differences among beach mouse subspecies, and it is, in fact, these colour differences that provided the basis for their subspecific designations (Osgood 1909;Howell 1939).…”

“…Only two keys (Osgood, 1909;Hall and Kelson, 1959) are available that include all species in the genus. The degree of geographic variation within many species is such that the characters used in these keys are not useful for species recognition in all geographic areas.…”

“…Haplomylomys has traditionally included at least two species groups: californicus (a species restricted to the California chaparral) and eremicus (including merriami of the Sonoran Desert, eva of the Baja California Peninsular Desert, and the widespread desert species, eremicus). Osgood (1909) included one other desert species (crinitus) within Haplomylomys, which was later transferred to Peromyscus by Hooper and Musser (1964). Up to 9 species restricted to arid islands in the Sea of Cortéz have been included in the eremicus species group: caniceps, collatus (currently considered a subspecies of eremicus), dickeyi, guardia, interparietalis, pembertoni, pseudocrinitus, and possibly stephani and slevini.…”

Phylogeographic relationships among 26 populations from throughout the geographic range of the Peromyscus eremicus species group are described based on sequence data for a 699-bp fragment of the mitochondrial DNA COIII gene. Distance, maximum-likelihood, and maximum-parsimony analyses of phylogenetic trees generated under four separate character-weighting strategies and representing five alternative biogeographic hypotheses revealed the existence of a cryptic species (Peromyscus fraterculus, previously included under P. eremicus) on the Baja California Peninsula and adjacent southwestern California and two distinct forms of P. eremicus, one from the Mojave, Sonoran, and northwestern Chihuahuan regional deserts (West) and one from the remainder of the Chihuahuan Desert (East). Distinctiveness of P. fraterculus is supported by previous morphometric and allozyme analyses, including comparisons with neighboring P. eremicus and parapatric P. eva, with which P. fraterculus shares a sister taxon relationship. Divergence of the eva ؉ fraterculus, West ؉ East eremicus, and P. merriami haplotype lineages likely occurred in the late Neogene (3 Ma), in response to northern extension of the Sea of Corté z and elevation of the Sierra Madre Occidental; divergence of eva from fraterculus is concordant with the existence of a trans-Peninsular seaway during the Pleistocene (1 Ma); and divergence of West from East eremicus occurred during the Pleistocene pluvial-interpluvial cycles, but well before the Wisconsinan glacial interval. The sequence of divergence within the eremicus species group and causal association of geological events of the Neogene and Holocene provide a working hypothesis against which phylogeographic patterns among other arid-adapted species of the warm regional deserts of North America may be compared. © 2000 Academic Press Key Words: biogeography; phylogeography; systematics; North American deserts; mitochondrial DNA; rodents; Peromyscus eremicus; Peromyscus eva; Peromyscus merriami; Peromyscus fraterculus. INTRODUCTIONKnowledge of the diversification and distribution of taxa and biotas through time is fundamentally based on our understanding of the geographic distribution of and relationships among evolutionary lineages. For example, debate over the prevalence of vicariance versus dispersal will reflect the extent to which similarity among populations fails to obscure historical divergence among evolutionary lineages. Reconstructions of biogeographic history will necessarily be wrong if paraphyletic or polyphyletic lineages are erroneously interpreted to be monophyletic.We might expect basic biogeographic patterns in the North American mammal fauna to be relatively well characterized, given a century of intensive systematic and biogeographic investigations that began with the creation of the United States Biological Survey in the late 1800s (Hoffmeister and Sterling, 1994). Instead, molecular-based studies repeatedly reveal cryptic evolutionary lineages embedded within long-recognized species of North Americ...
