Phylogenetics of Sigmodontinae (Rodentia, Muroidea, Cricetidae), with special reference to the akodont group, and with additional comments on historical biogeography
TLDR
This is the first cladistic analysis of sigmodontine rodents (Cricetidae, Sigmodontinae) based on nuclear and mitochondrial DNA sequences and it is shown that Euneomys is not a phyllotine and that the Reithrodon group is not monophyletic.
Species groups and the evolutionary diversification of tuco-tucos, genus Ctenomys (Rodentia: Ctenomyidae)
TLDR
The most comprehensive study to date of species groups in Ctenomys (tuco-tucos), a species-rich genus of Neotropical rodents, estimates that most species groups originated approximately 3 million years ago.
Genetic footprints of late Quaternary climate change in the diversity of Patagonian-Fueguian rodents.
TLDR
demographic instability in response to historical climate change has been widespread in the Patagonian-Fueguian region, and is generally more pronounced at high latitudes in both southern and northern continents; but in situ differentiation has also contributed to species diversity.
A phylogenetic appraisal of Sigmodontinae (Rodentia, Cricetidae) with emphasis on phyllotine genera: systematics and biogeography
TLDR
A comprehensive phylogenetic analysis based on nuclear and mitochondrial DNA sequences of rodents of the subfamily Sigmodontinae suggests that the historical biogeography of the sigmodontine rodents is far more complex than earlier envisioned.
Rodent systematics in an age of discovery: recent advances and prospects
TLDR
An overview of changes in the understanding of the systematics of living rodents, including species recognition and delimitation, phylogenetics, and classification, with emphasis on the last three decades is provided.
Taxonomy based on science is necessary for global conservation

Mitogenomics of southern hemisphere blue mussels (Bivalvia: Pteriomorphia): Insights into the evolutionary characteristics of the Mytilus edulis complex
TLDR
The phylogenetic analyses supported the monophyly of Pteriomorphia and fully resolved the phylogenetic relationships among its five orders and the low genetic divergence of specimens assigned to M. chilensis and M. platensis suggests that these South American marine mussels represent conspecific variants rather than distinct species.
DEFINITION AND DIAGNOSIS OF A NEW TRIBE OF SIGMODONTINE RODENTS (CRICETIDAE: SIGMODONTINAE), AND A REVISED CLASSIFICATION OF THE SUBFAMILY
TLDR
A new tribe of sigmodontine rodents is formally defined and diagnosed that presents a unique combination of characters including nasals and premaxilla usually projected anterior to the incisors, moderately trumpeted and zygomatic plate with upper free border reduced or obsolete.
