The possibility that the Peromyscus maniculatus complex of deer mice arose via the process described as "centrifugal speciation" (Brown, 1957) has been discussed by Bowers et al., 1973, Lawlor, 1974, Baker et al., 1975, and Greenbaum et al., 1978. This study was designed to yield additional data on the cytogenetics of three species of this complex in order to evaluate the "centrifugal speciation" model as a viable explanation of the evolutionary origin of the complex. Peromyscus melanotis and P… 
CHROMOSOMAL VARIATION IN PEROMYSCUS MANICULATUS POPULATIONS ALONG AN ELEVATIONAL GRADIENT
TLDR
The present study was undertaken to determine the Q-banded karyotypes of mice from all the altitudes sampled, and to determine whether there were mice heteromorphic for an inversion in chromosome 6, and if gene flow exists among the different altitudes, some hybrid individuals for chromosome pair 6 are expected.
Evolutionary implications of microsatellite variation in the Peromyscus maniculatus species group
TLDR
Theoretical predictions and empirical studies indicate that phylogenetic analyses based on microsatellite primers isolated from a focal species may be subject to ascertainment biases that can be expected to degrade the efficacy of this approach with increasing phylogenetic depth between the species from which the microsatellites were isolated and those to which these loci are being compared.
EXTENSIVE GENETIC VARIATION IN MITOCHONDRIAL DNA'S AMONG GEOGRAPHIC POPULATIONS OF THE DEER MOUSE, PEROMYSCUS MANICULATUS
TLDR
The data presented in this paper are of considerable significance to two different but closely interrelated aspects of mtDNA evolution: the use of restriction endonucleases to measure mitochondrial DNA sequence relatedness in natural populations and the observation that samples from Colorado and southern Michigan were very similar in mtDNA sequence.
Mitochondrial DNA differentiation during the speciation process in Peromyscus.
TLDR
The theoretical and empirical results for mtDNA in maniculatus and polionotus appear to conform closely to case III, and it is suggested that the distribution patterns of mtDNA sequence variation within and among extant species should be of considerable relevance to the particular demographies of speciation.
A new sibling species of Taterillus (Muridae, Gerbillinae) from West Africa
TLDR
It is illustrated how cytogenetics can contribute to the description of sibling species and hence to biodiversity as well as important issues in applied research such as in conservation biology or pest species control.
Mitochondrial-DNA Analysis of the Systematic Relationships within the Peromyscus maniculatus Species Group
TLDR
The parsimony and distance-based phylogenetic analyses of sequence data from three mitochondrial DNA genes revealed that, as currently recognized, the Peromyscus maniculatus species group is polyphyletic and that P. coolidgei is closer to P. sejugis than to the other subspecies of P. manicuatus examined.
New developments in vertebrate cytotaxonomy VII
TLDR
The results presented show that the contribution of banding methods to cytotaxonomic analysis is considerable and the problem of interspecific phyletic relations will be stated in terms of genomic organization, DNA diversity, chromatin nature and repartition of different genome fractions, the relative value of the numerical criteria having consequently diminished.
Microsatellite variation and evolution in the Peromyscus maniculatus species group.
TLDR
Significantly lower levels of variation and the distribution of alleles in the two populations of the insular-endemic P. sejugis were consistent with the expectation of substantial founder effect and suggest a lack of recent gene flow between these populations, but microsatellite data do not support the hypothesis that P. leucopus should be considered conspecific with P. maniculatus.
Patterns of karyotype evolution in complexes of sibling species within three genera of African murid rodents inferred from the comparison of cytogenetic and molecular data
TLDR
The analysis of three rodent sibling species complexes belonging to the African genera Arvicanthis, Acomys and Mastomys revealed that each complex is characterized by a distinct pattern of karyotype evolution (karyotypic orthoselection), and a specific mutation rate, and the general pattern may be considerably modified in the course of evolution within the same species complex.
Chromosomal evolution of the brown mice, genus Scotinomys (Rodentia: Cricetidae)
TLDR
Ch Chromosomally, golden mice (Ochrotomys) were found to be most similar to Scotinomys, this association based on two apparent synapomorphic G-banded chromosomes supports a hypothesis that treats Scotinoms, Ochrotomsys, and perhaps Baiomys as a rather loosely associated assemblage of genera that are phylogenetically intermediate between the relatively complex pene, primarily South American cricetine rodents.

CHROMOSOMAL HOMOLOGY AND DIVERGENCE BETWEEN SIBLING SPECIES OF DEER MICE: PEROMYSCUS MANICULATUS AND P. MELANOTIS (RODENTIA, CRICETIDAE)
TLDR
The chromosomal homologies and types of chromosomal rearrangements between two members of this complex, P. melanotis and P. maniculatus, are determined by Gand Cband comparisons.
ECOLOGICAL FACTORS IN SPECIATION OF PEROMYSCUS
TLDR
The purpose here is to summarize what is presently known about geographic differentiation and speciation in Peromyscus and to indicate some major evolutionary problems to which work in this group may offer an eventual solution.

CHROMOSOMAL, ELECTROPHORETIC, AND BREEDING STUDIES OF SELECTED POPULATIONS OF DEER MICE (PEROMYSCUS MANICULATUS) AND BLACK‐EARED MICE (P. MELANOTIS)
TLDR
The deer mouse, Peromyscus maniculatus, has the widest geographic distribution of the native species of rodents in North America and an analysis of genetic relationship of such populations provides a valuable approach to the study of mammalian evolution.
Genetic compatibility of Peromyscus maniculatus and Peromyscus melanotis, as indicated by breeding studies and morphometrics.
TLDR
Comparisons ofroductive compatibility, skull morphometrics, color of pelage, and size and structure of bacula and sperm were compared in nine populations of Peromyscus maniculatus and P. melanotis from the southwestern United States and Mexico, finding no basis for subspecies distinction can be found.
REPLY TO COMMENTS ON “CHROMOSOMAL EVOLUTION IN PEROMYSCUS”
TLDR
It is admitted that in the majority of systems where the fundamental number remains constant the direction of change will more often prove to be the result of fusions than fissions, but how much the balance will favor fusions remains unclear to us.

Chromosomal polymorphism in Peromyscus polionotus.
TLDR
A structural polymorphism involving a moderately small pair of auto-somes was detected in oldfield mice, Peromyscus polionotus, and could be attributed to a single inversion widely distributed in the species.
Standardized karyotype of deer mice, Peromyscus (Rodentia)
TLDR
A standard G-band karyotype is proposed for the genus Peromyscus and its chromosomes are numbered and arranged according to chromosome number.
