| Desert wood rat, North America | |
| "We review the evolutionary history and systematic status of species and subspecies of the desert woodrat complex of the Neotoma lepida group. Currently, this complex comprises six taxa currently recognized as species from western North America, two “continental” (Neotoma lepida Thomas and Neotoma devia Goldman) and four from islands on both the Pacific and gulf sides of Baja California (Neotoma anthonyi [Todos Santos], Neotoma martinensis [San Martín], Neotoma bryanti [Cedros], and Neotoma bunkeri [Coronados]). In this review, we examined more than 4600 museum specimens for morphological characters, both qualitative and quantitative craniodental, male phallic, and colorimetric variables, analyzed mitochondrial DNA (mtDNA) sequence data for the cytochrome-b gene and allelic variation for 18 nuclear microsatellite loci from more than 1000 individuals, and nuclear DNA sequences (nucDNA) from intron 7 of the -fibrinogen gene (Fgb-I7) from 166 specimens. We analyzed morphological data by a combination of univariate and multivariate methods to define discrete groups in nature and to document patterns of variation across geography. We applied phylogenetic analyses to delineate geographic clusters that are evolutionarily independent and examined the concordance between these lineages and morphological groupings. We used population genetic methods to determine the degree to which there is genetic exchange between phylogenetic and morphological groups where they co-occur in nature. We then used coalescent approaches to develop hypotheses about the timing and processes that underlie diversification of the molecular and morphological groups that we identified. Finally, we examined a set of testable, objective criteria that can be used to bound species groups in nature, and we rearranged the taxonomy of this group of woodrats according to those criteria. Our analyses, applications, and results confirm the inadequacy of the current systematics of the Neotoma lepida group..." | |
