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 metatherian mammals. [] Key Result These observations, representing evolved differences in diverse functional-morphological systems, together with karyotypic information gleaned from the literature, provide the basis for coding 129 phylogenetic characters that we scored for 44 ingroup and seven outgroup taxa…

Molecular and morphological evidence of the diversification in the gray mouse opossum, Tlacuatzin canescens (Didelphimorphia), with description of a new species

TLDR
The molecular clock estimates indicate that the diversification of this taxon occurred during the Pleistocene, which suggests that climatic changes and the presence of geographical barriers influenced the genetic differentiation of its populations.

New morphological data and phylogenetic position of the rare short-tailed opossum Monodelphis ronaldi (Didelphimorphia: Didelphidae) with new records

TLDR
The authors' analyses recovered M. ronaldi as the sister species of M. handleyi, confirming its position within the subgenus Mygalodelphys .

Craniodental Morphology and Phylogeny of Marsupials

TLDR
The results of separate and combined analyses of these data using a wide range of phylogenetic methods support many currently accepted hypotheses of ingroup (marsupial) relationships, but they also underscore the difficulty of placing fossils with key missing data.

An emerging consensus in the evolution, phylogeny, and systematics of marsupials and their fossil relatives (Metatheria)

Marsupials and their fossil relatives, which collectively comprise Metatheria, have been of scientific interest for centuries, with many aspects of their evolution and systematics subject to intense

Taxonomic status and phylogenetic relationships of Marmosa agilis peruana Tate, 1931 (Didelphimorphia: Didelphidae), with comments on the morphological variation of Gracilinanus from central–western Brazil

TLDR
An emended diagnosis, description and comparisons with congeners for G. peruanus, a marsupials of the family Didelphidae that ranges from central Peru to central Bolivia and western Brazil in the states of Rondonia and northwestern Mato Grosso, where it occurs in sympatry with G. agilis.

Cytogenetics meets phylogenetics: a review of karyotype evolution in diprotodontian marsupials.

TLDR
Karyotypes changes are discussed in the context of current hypotheses concerning centromeres, chromosomal fragile sites, and mobile elements in marsupials and the probable repeated involvement of these elements in karyotypic restructuring.

Molecular Systematics of Mouse Opossums (Didelphidae: Marmosa): Assessing Species Limits using Mitochondrial DNA Sequences, with Comments on Phylogenetic Relationships and Biogeography

TLDR
Preliminary phylogenetic analyses of sequence data from the mitochondrial cytochrome-b gene representing 12 of the 14 morphologically defined taxa recently treated as valid species of Marmosa (Marmosa) in the aforementioned revisionary work support the recognition of M. isthmica and M. simonsi as species distinct from M. robinsoni, and the recognitionof M. waterhousei asspecies distinct fromM.

Mammals from ‘down under’: a multi-gene species-level phylogeny of marsupial mammals (Mammalia, Metatheria)

TLDR
The first Methaterian species-level phylogeny to include 80% of the extant marsupial species and five nuclear and five mitochondrial markers obtained from Genbank and a recently published retroposon matrix is presented, offering a well resolved and detailed tool for comparative analyses.

Species Limits and Phylogenetic Relationships in the Didelphid Marsupial Genus Thylamys Based on Mitochondrial DNA Sequences and Morphology

TLDR
Thylamys species limits are examined, morphological diagnoses are provided, information about geographic distributions is summarized, comment on previous misidentifications, and historical-biogeographic scenarios are briefly considered with a focus on dispersal events across the Andes.

Marsupial and monotreme evolution and biogeography

TLDR
The known fossil record and biogeography of both radiations is summarised, with particular attention given to a recent paradigm shift on monotreme evolution, with the latest research suggesting that monotremes are part of an ancient, Gondwanan radiation of mammals that independently evolved a tribosphenic dentition.

PHYLOGENETIC RELATIONSHIPS OF THE MARSUPIAL GENUS HYLADELPHYS BASED ON NUCLEAR GENE SEQUENCES AND MORPHOLOGY

Abstract Phylogenetic analyses of sequence data from the nuclear gene encoding the interphotoreceptor retinoid–binding protein (Irbp) provide compelling evidence that the recently described Amazonian

A Phylogeny and Timescale for Marsupial Evolution Based on Sequences for Five Nuclear Genes

TLDR
The authors' UBBL estimates of the marsupial fossil record indicate that the South American record is approximately as complete as the Australasian record, and all methods provide strong support for the monophyly of Australidelphia.

PHYLOGENETIC STUDIES ON DIDELPHID MARSUPIALS II. NONMOLECULAR DATA AND NEW IRBP SEQUENCES: SEPARATE AND COMBINED ANALYSES OF DIDELPHINE RELATIONSHIPS WITH DENSER TAXON SAMPLING

TLDR
A combined (simultaneous) maximum-parsimony analysis of both datasets (nonmolecular + IRBP) produced a consensus topology that closely resembled the results of analyzing IRBP separately, and a new genus is described for “Marmosa” canescens.

Relationships among didelphid marsupials based on sequence variation in the mitochondrial cytochrome B gene

TLDR
Variation in the mitochondrial cytochrome b gene is evaluated for 9 genera and 15 species of American opossums in the family Didelphidae, using the American caenolestid rat opossum Lestoros and the New Guinean peroryctid bandicoot Echimypera as outgroups.

The phylogenetic relationships of argyrolagid marsupials

TLDR
Eleven features support the monophyly of Paucituberculata, the following three unique among Marsupialia: small size of the paraconid, procumbent second lower incisor, and supraoccipital without distinct lambdoid crest resulting in globular form of braincase.

Molecular phylogeny of living xenarthrans and the impact of character and taxon sampling on the placental tree rooting.

TLDR
Maximum likelihood and Bayesian phylogenetic analyses of a 47 placental taxa data set resolved the phylogeny of Xenarthra with some evidence for two radiation events in armadillos and provided a strongly supported picture of placental interordinal relationships.

Carnivorous dental adaptations in tribosphenic mammals and phylogenetic reconstruction

TLDR
The molar morphology and structure of seven groups of flesh-eating mammals are compared and character states should be used with extreme care in reconstructing phylogeny and, when possible, associated to cranial features are discussed.

CLADISTIC ANALYSIS OF DASYUROMORPHIAN (MARSUPIALIA) PHYLOGENY USING CRANIAL AND DENTAL CHARACTERS

TLDR
For some groups, notably Dasyuridae and a dasyurid clade inclusive of all modern subfamilies, the synapomorphic nature of some derived features appears to be robust, even where they also are present in some outgroup taxa.
