“…Genetic distance measures may be useful for the determination of species boundaries and, in accordance with the hypothesis of cryptic species in small mammals (Bradley and Baker ; Baker and Bradley ), levels of mitochondrial differentiation as those found in this study have been used as criteria for the description of new forms of Peromyscus (Bradley et al. , ).…”

The mountain mice of the Peromyscus mexicanus group currently encompass six known species; however, the limits between species remain uncertain, with two considered monotypic and the other four having multiple associated subspecific names. Based on the most comprehensive sampling of the group throughout its distribution in Nuclear Central America, we used data of the mitochondrial cytochrome b gene to assess its genetic diversity, phylogeny, and main biogeographic and diversification patterns. Our mitochondrial phylogeny only partially reflects the current taxonomy of the group, in agreement with some of the taxonomically recognized species. Specifically, our phylogenetic results show that the group is highly structured, including four main clades with genetic distances ranging from 11 to 8.6%. A remarkable level of differentiation is found at a more local level, defined as 15 different lineages with high nucleotide and haplotype diversity (p = 0.068, h = 0.99), and with divergence and genetic distance values (p-uncorrected = 9.9-2.4%; K2P = 10.8-3.0%) similar to values observed between species within Peromyscus. Accordingly, we propose that the reference name P. mexicanus is polyphyletic and should be restricted to the mountains of central Mexico west of the Isthmus of Tehuantepec. We suggest to limit the other five recognized specific names to equal number of lineages, as monophyletic, and to revalidate three junior synonyms: Peromyscus salvadorensis, P. nicaraguae and P. tropicalis. The Isthmus of Tehuantepec, the Motagua-Polochic-Jocot an fault system, the Maya Highlands and the Honduras Depression are examples of geographic features that are likely associated with the differentiation of main lineages. Some other lineages may represent candidate species, hence the need to review the taxonomic status of the entire P. mexicanus group.

“…Although several recent studies have focused on developing phylogenies for Peromyscus (sensu lato and sensu stricto) and its affiliated genera, for a variety of reasons, none have been able to offer unambiguous taxonomic recommendations. First, Peromyscus is a large genus with new species still being described (Bradley et al 2004a(Bradley et al , 2014; complete taxonomic sampling is often difficult. Second, because several character systems have been studied and analyzed, it presents a challenge to resolve discrepancies when there are conflicting data.…”

The evolutionary relationships between ,, ,, ,, and are poorly understood. In order to further explore the evolutionary boundaries of and compare potential taxonomic solutions for this diverse group and its relatives, we conducted phylogenetic analyses of DNA sequence data from alcohol dehydrogenase (1-I2), beta fibrinogen (-I7), interphotoreceptor retinoid-binding protein (3), and cytochrome- (). Phylogenetic analyses of mitochondrial and nuclear genes produced similar topologies although levels of nodal support varied. The best-supported topology was obtained by combining nuclear and mitochondrial sequences. No monophyletic clade was supported. Instead, support was found for a clade containing, ,, ,, and suggesting paraphyly of and confirming previous observations. Our analyses indicated an early divergence of from (approximately 8 million years ago), whereas most other peromyscine taxa emerged within the last 6 million years. To recover a monophyletic taxonomy from and affiliated lineages, we detail 3 taxonomic options in which, ,, , and are retained as genera, subsumed as subgenera, or subsumed as species groups within . Each option presents distinct taxonomic challenges, and the appropriate taxonomy must reflect the substantial levels of morphological divergence that characterize this group while maintaining the monophyletic relationships obtained from genetic data.

“…Because rodents may have distributions that are restricted to small areas and microhabitats, and because sampling is far from complete, we may be missing species with restricted distributions. Evidence that this is more than speculation is the description of a new species of deer mouse Peromyscus carletoni Bradley et al, 2014, or the pocket gopher Thomomys nayarensis Mathis et al, 2013b from the highlands of Nayarit, in areas very close to SPMRB, and associated to vegetation types that also are present in the basin. The apparent overrepresentation of bats and carnivores might just be the result of the relatively low numbers of recorded rodents, which lowers the percentage of the latter while increasing that of the former.…”

The San Pedro–Mezquital River Basin is located in the southern Sierra Madre Occidental, at the Nearctic– Neotropical transition. The river traverses the Sierra through a canyon that reaches over 1000 m in depth. Based on examination of museum specimens, literature records, and our own collections, we documented the occurrence of 120 species (24.6% of the Mexican terrestrial mammals), 24 endemic to Mexico. Richness was comparable with other megadiverse areas of Mexico, and higher than any other Nearctic–Neotropical transition area, moreover species richness is likely to rise as survey continues. Contrary to expectation, distribution of mammals across the basin not only reflected the Nearctic–Neotropical divide, but a third fauna that is a mixture of tropical, temperate and desert species was identifiable at the canyon. Anthropogenic threats including damming of the river, uncontrolled cattle grazing, and pollution from domestic sources, call for effective management strategies to preserve one of the most biodiverse areas of Mexico.
