We also examined Myotis annectans from Southeast Asia, and Myotis macropus from Australia. The two species of Cistugo and Myotis annectans represent the only species of Myotis to differ in chromosome number from the common 2n=44 found in >40 species. Our results show that the two species of Cistugo are more divergent from the other species of Myotis than several other well-recognized genera and we recommend elevating Cistugo to full generic rank. Myotis annectans groups well within Myotis, clustering with other Southeast Asian and Japanese species, and thus represents the only species of Myotis known to have diverged from the common 2n=44 karyotype. Myotis macropus clusters within a clade that includes Southeast Asian species.

Nucleotide sequence variation among 22 representatives of 14 families of hystricognathid rodents ... more Nucleotide sequence variation among 22 representatives of 14 families of hystricognathid rodents was examined using an 814-bp region of the mitochondrial 12S ribosomal RNA (rRNA) gene composing domains I-III. The purpose of this study was twofold. First, the phylogenetic relationships among Old World phiomorph (primarily African) and New World caviomorph (primarily South American) families were investigated, with a special emphasis on testing hypotheses pertaining to the origin of New World families and the identification of major monophyletic groups. Second, divergence times derived from molecular data were compared to those suggested by the fossil record. The resultant 12S rRNA gene phylogeny, analyzed separately and in combination with other morphological and molecular data, supported a monophyletic Caviomorpha. This finding is counter to the idea of a multiple origin for the South American families. The most strongly supported relationships within the Caviomorpha were a monophyletic Octodontoidea (containing five families) and the placement of New World porcupines (family Erethizontidae) as the most divergent family. Although comparisons to other data were more equivocal, the most parsimonious 12S rRNA trees also supported a monophyletic Phiomorpha that could be subdivided into two major groups, a clade containing the Thryonomyoidea (Thryonomyidae and Petromuridae) plus Bathyergidae and the more divergent Hystricidae (Old World porcupines). No significant differences in rates of 12S rRNA gene divergence were observed for hystricognathids in comparison to other rodent groups. Although time since divergence estimates were influenced by the fossil dates chosen to calibrate absolute rates, the overall divergence times derived from both transversions only and Kimura corrected distances and calibrations using two independent dates revealed a divergence time between Old and New World groups dating in the Eocene.

Randomly amplified polymorphic DNA (RAPD) and arbitrarily primed PCR (AP-PCR) represent novel DNA... more Randomly amplified polymorphic DNA (RAPD) and arbitrarily primed PCR (AP-PCR) represent novel DNA polymorphism assays that involve the amplification of random DNA segments using PCR and oligonucleotide primers of arbitrary sequence. Products defining the polymorphisms exhibit Mendelian inheritance and thus possess tremendous potential utility as genetic markers in a diverse array of scientific disciplines. Amplification profiles for specific oligonucleotide primers are highly dependent on the specific conditions of the reaction; banding patterns may thus vary extensively because of inconsistencies in a number of reaction parameters. Artifactual variation represents a potential problem in surveys of genetic variation in natural populations and must be discriminated from true polymorphism for the applications of RAPD to be both accurate and reliable.
