An Assessment of the Systematics of Arvicanthine Rodents Using Mitochondrial DNA Sequences: Evolutionary and Biogeographical Implications
The identification of the Otomyinae as the sister-taxon to Arvicanthini implies that the former are true murines and should be given only tribal rank within the Murinae, suggesting the possibility of a rapid radiation within this set of species. Expand
Cytogenetics and cladistics.
Chromosomal data have been underutilized in phylogenetic investigations despite the obvious potential that cytogenetic studies have to reveal both structural and functional homologies among taxa. In… Expand
The List of the Chromosome Races of the Common Shrew (Sorex Araneus)
The list of chromosome races of the common shrew (Sorex araneus) was compiled, the vast literature has been scrutinized, and unpublished data have been added. Altogether, 50 chromosome races could be… Expand
Viability of X-autosome translocations in mammals: an epigenomic hypothesis from a rodent case-study
An epigenomic hypothesis is proposed which posits that constitutive heterochromatin is probably selected for in X-autosome translocations since it may protect the inactivated X from spreading to the autosomal part, and allow for the independent regulation of replication timing of the sex and autosomal segments.

Recent radiation in West African Taterillus (Rodentia, Gerbillinae): the concerted role of chromosome and climatic changes

It is hypothesize that the process underpinning cladogenesis most probably involved highly underdominant genomic rearrangements that were fixed following pronounced populational bottlenecks resulting from drastic climatic and subsequent environmental changes. Expand
Threatened rodents in Europe: species status and some suggestions for conservation strategies
A definition of a chromosome race of the common shrew (Sorex araneus) is proposed, and supplemented by rules and conventions to name, group and describe the races.
A molecular perspective on the systematics and evolution of the genus Arvicanthis (Rodentia, Muridae): inferences from complete cytochrome b gene sequences.

- 1 August 1998
The complete mitochondrial cytochrome b gene was sequenced for 20 specimens from throughout the range of the genus to determine the intrageneric genetic structure, construct a molecular phylogeny, and evaluate classical taxonomies. Expand
Comparative genome maps of the pangolin, hedgehog, sloth, anteater and human revealed by cross-species chromosome painting: further insight into the ancestral karyotype and genome evolution of…
These maps demonstrate the conservation of such syntenic segment associations as HSA3/21, 4/8, 7/16, 12/22, 14/15 and 16/19 in Eulipotyphla, Pholidota and Xenarthra and thus further consolidate the notion that they form part of the ancestral karyotype of the eutherian mammals. Expand
Low rate of genomic repatterning in Xenarthra inferred from chromosome painting data
A molecular cytogenetic comparison of chromosomes from the two- toed and three-toed sloth species and an anteater and sloth genomes provides a glimpse of a likely ancestral karyotype for the extant Xenarthra, a pivotal group for understanding eutherian genome evolution. Expand
Karyotype evolution and phylogenetic relationships of hamsters (Cricetidae, Muroidea, Rodentia) inferred from chromosomal painting and banding comparison

- 10 May 2007
Based on results of chromosome painting and G-banding, comparative maps between 20 rodent species have been established and demonstrate a high level of karyotype conservation among species in the Cricetus group with Tscherskia as its sister group. Expand
