The pattern and timing of diversification of Philippine endemic rodents: evidence from mitochondrial and nuclear gene sequences.
- S. Jansa, F. K. Barker, L. Heaney
- Medicine, Biology
- Systematic biology
- 1 February 2006
The 22 genera and 64 species of rodents (Muridae: Murinae) distributed in the Philippine Islands provide a unique opportunity to study patterns and processes of diversification in island systems.… Expand
Phylogenetic Relationships and Classification of Didelphid Marsupials, an Extant Radiation of New World Metatherian Mammals
Abstract This report summarizes a decade of morphological and molecular research on the phylogenetic relationships of didelphid marsupials (opossums), a substantially intact radiation of New World… Expand
Phylogeny of muroid rodents: relationships within and among major lineages as determined by IRBP gene sequences.
- S. Jansa, M. Weksler
- Biology, Medicine
- Molecular phylogenetics and evolution
- 1 April 2004
The rodent family Muridae is the single most diverse family of mammals with over 1300 recognized species. We used DNA sequences from the first exon ( approximately 1200bp) of the IRBP gene to infer… Expand
PHYLOGENETIC STUDIES ON DIDELPHID MARSUPIALS II. NONMOLECULAR DATA AND NEW IRBP SEQUENCES: SEPARATE AND COMBINED ANALYSES OF DIDELPHINE RELATIONSHIPS WITH DENSER TAXON SAMPLING
Abstract In order to test the results of a previous study of didelphid marsupial phylogeny based on IRBP nuclear gene sequences (Jansa and Voss, 2000. Phylogenetic studies on didelphid marsupials I.… Expand
On the Contents of Gracilinanus Gardner and Creighton, 1989, with the Description of a Previously Unrecognized Clade of Small Didelphid Marsupials
Abstract Five nominal species of small didelphid marsupials previously referred to Gracilinanus differ conspicuously from the type species (G. microtarsus) and from all of the other valid taxa that… Expand
Phylogenetic relationships in the genus mus, based on paternally, maternally, and biparentally inherited characters.
- B. Lundrigan, S. Jansa, P. Tucker
- Biology, Medicine
- Systematic biology
- 1 May 2002
Several species in the rodent genus Mus are used as model research organisms, but comparative studies of these mice have been hampered by the lack of a well-supported phylogeny. We used DNA sequences… Expand
Phylogenetic Studies on Didelphid Marsupials I. Introduction and Preliminary Results from Nuclear IRBP Gene Sequences
We report and analyze nucleotide sequence variation in the first exon (1158 bp) of the nuclear gene encoding the Interphotoreceptor Retinoid Binding Protein (IRBP) among 21 species representing all… Expand
THE EARLY DIVERSIFICATION HISTORY OF DIDELPHID MARSUPIALS: A WINDOW INTO SOUTH AMERICA'S “SPLENDID ISOLATION”
- S. Jansa, F. K. Barker, R. Voss
- Biology, Medicine
- Evolution; international journal of organic…
- 1 March 2014
The geological record of South American mammals is spatially biased because productive fossil sites are concentrated at high latitudes. As a result, the history of mammalian diversification in… Expand
Molecular Phylogeny and Biogeography of the Native Rodents of Madagascar (Muridae: Nesomyinae): A Test of the Single‐Origin Hypothesis
- S. Jansa, S. M. Goodman, P. Tucker
- Biology
- 1 September 1999
Complete nucleotide sequences from the mitochondrial cytochrome b gene (1143 bp) were used to investigate the phylogenetic relationships among the native rodents of Madagascar. Specifically, this… Expand
Base-compositional heterogeneity in the RAG1 locus among didelphid marsupials: implications for phylogenetic inference and the evolution of GC content.
- Karl F. Gruber, R. Voss, S. Jansa
- Biology, Medicine
- Systematic biology
- 1 February 2007
Although theoretical studies have suggested that base-compositional heterogeneity can adversely affect phylogenetic reconstruction, only a few empirical examples of this phenomenon, mostly among… Expand
