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 …

The structure, physiology, and endocrinology of the yolk sac placenta of different marsupial
groups is compared and phylogenetically analyzed to provide information on placental …

A review of paleontological, phyletic, geophysical, and climatic evidence leads to a new
scenario of land mammal dispersal among South America, Antarctica, and Australia in the …

We review past DNA-hybridisation studies of marsupials and present a reanalysis of the
data, utilising results from our and additional studies to formulate and rationalise a new …

The phylogenetic relationship among primates, ferungulates (artiodactyls+ cetaceans+
perissodactyls+ carnivores), and rodents was examined using proteins encoded by the H …

Higher-level relationships within, and the root of Placentalia, remain contentious issues.
Resolution of the placental tree is important to the choice of mammalian genome projects …

The dynamic onset of DNA fragmentation in mammalian sperm populations varies widely in
different species when the spermatozoa are incubated in vitro at body temperature for …

Comparative studies require information on phylogenetic relationships, but complete
species-level phylogenetic trees of large clades are difficult to produce. One solution is to …

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 …

Phylogenetic relationships among marsupial taxa have proven to be more complex than the
simple grouping of species by continent. Recent marsupials are distributed across the New …
