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

A recently improved understanding of gut immunity has merged with current thinking in
biological and medical science, pointing to an apparent function of the mammalian cecal …

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 …

The orbital apertures of Primates are among the most convergent (ie, facing in the same
direction) among mammals. It is often assumed that orbit convergence is associated with …

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 …

Even though the marsupial order Diprotodontia is one of the most heavily studied groups of
Australasian marsupials, phylogenetic relationships within this group remain contentious …

Throughout their evolutionary histories, marsupial mammals have been taxonomically and
morphologically less diverse than their sister taxa the placentals. Because of this, it has …

Relationships among the seven extant orders of marsupials remain poorly understood. Most
classifications recognize a fundamental split between Ameridelphia, which contains the …

The anatomy of Arctodictis sinclairi (Sparassodonta, Borhyaenidae) is studied in detail in
this work and constitutes the core of the present contribution. The specimen MLP 85-VII-3-1 …

We combine osteological, dental, and soft tissue data with sequences from three nuclear
and five mitochondrial genes, sampling all major living clades of marsupials plus several …
