The Placental Mammal Ancestor and the Post–K-Pg Radiation of Placentals
A phylogenetic tree shows that crown clade Placentalia and placental orders originated after the K-Pg boundary, but phenomic signals overturn molecular signals to show Sundatheria (Dermoptera + Scandentia) as the sister taxon of Primates, a close link between Proboscidea and Sirenia (sea cows), and the monophyly of echolocating Chiroptera (bats).
Phylogenetic Relationships of Oryzomine Rodents (Muroidea: Sigmodontinae): Separate and Combined Analyses of Morphological and Molecular Data

A phylogenetic hypothesis for the tribe Oryzomyini is provided that can be used to understand the diversification and evolution of this group of rodents and to revise the current generic-level classification.
Ten New Genera of Oryzomyine Rodents (Cricetidae: Sigmodontinae)
10 new genera are described for species or species groups previously referred to the polyphyletic genus Oryzomys, and the tribe OryZomyini now comprises 28 genera, which are morphologically diagnosable and have distinct ecogeographic distributions.

A temporal and spatial framework is provided to address key aspects of the historical biogeography and diversification of this diverse mammal group by using mitochondrial and nuclear DNA datasets coupled with methods of divergence time estimation, ancestral area reconstruction and comparative phylogenetics.
A new genus and species of rodent from the Brazilian Atlantic Forest (Rodentia: Cricetidae: Sigmodontinae: Oryzomyini), with comments on oryzomyine biogeography
A new genus and species of cricetid rodent from the Atlantic Forest of Brazil, one of the most endangered eco-regions of the world, is described, which displays some but not all synapomorphies of the tribe Oryzomyini.
STATUS OF PROECHIMYS ROBERTI AND P. ORIS (RODENTIA: ECHIMYIDAE) FROM EASTERN AMAZONIA AND CENTRAL BRAZIL
Results, coupled with phylogenetic analysis of cytochrome-b sequences, indicate that P. roberti is a valid species of the guyannensis group and that the species of this group occurring in eastern Amazon, P. oris, is probably a junior synonym of P.roberti.

Survey of small mammals carried out in the Chapada dos Veadeiros National Park demonstrated that the cerrado has an endemic fauna and a little known diversity of small mammal species.
A newly recognized clade of trans-Andean Oryzomyini (Rodentia: Cricetidae), with description of a new genus
H aphrastus is best regarded as representing a new genus, which is described and named herein and forms a monophyletic group of mainly southern Central American and northern South American taxa primarily restricted to lowland to midelevation montane trans-Andean habitats and possessing a marked ability to cross expanses of salt water.
