The Placental Mammal Ancestor and the Post–K-Pg Radiation of Placentals
TLDR
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).
The evolution of South American endemic canids: a history of rapid diversification and morphological parallelism
TLDR
It is estimated that the most recent common ancestor of South American canids lived around 4 Ma, whereas all other splits within the clade occurred after the rise of the Panamanian land bridge, and a concatenated morphological and molecular analysis put some extinct canid species well within the South American radiation.
Bats of the state of Minas Gerais, southeastern Brasil
Minas Gerais is the largest state in the Southeastern of Brazil, and its location in the transition between the humid coastal Atlantic Forest and the drier Western and central Brazilian countryside
Phylogenetic Systematics of Peccaries (Tayassuidae: Artiodactyla) and a Classification of South American Tayassuids
TLDR
A computer assisted phylogenetic analysis using morphological and molecular data including fossil and extant Tayassuidae, recovering the monophyly and proposing to restrict the generic name to the type species, C. metropolitanus.
NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics.
TLDR
The main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if the xenarthran data is integrated with other data sets of Neotropic Series that will become available very soon.
Upper molar morphology and relationships among higher taxa in bats
TLDR
A standardized terminology for the upper molars of bats is proposed, taking into consideration the nomenclature adopted for tribosphenic mammals, and the tree obtained from parsimony analyses mostly agrees with previous proposals based on morphology.
Carnivores (Mammalia, Carnívora) from the Quaternary of Serra da Bodoquena, Mato Grosso do Sul, Brazil
A report on fossil remains of carnivores from the Quaternary of Serra da Bodoquena (Mato Grosso do Sul, Brazil), recovered from two limestone flooded caves, is presented. A total of six species could
Quaternary Bats from the Impossível-Ioiô Cave System (Chapada Diamantina, Brazil): Humeral Remains and the First Fossil Record of Noctilio leporinus (Chiroptera, Noctilionidae) from South America
TLDR
The first report of fossil bats from the partially submerged Impossível-Ioiô cave system in Bahia is provided, in which six species are recognized based on humeral remains: Furipterus horrens, Chrotopterus auritus, Mormoops cf.
Diversity, morphological phylogeny, and distribution of bats of the genus Molossus E. Geoffroy, 1805 (Chiroptera, Molossidae) in Brazil
TLDR
A hypothesis of phylogenetic relationships within Molossus based on morphology, establishing the morphological characters for diagnosis and identification of species, and update the geographic distribution of Molossus species in Brazil, with range extensions for four taxa are proposed.
Biogeographic scenarios for the diversification of a widespread Neotropical species, Glossophaga soricina (Chiroptera: Phyllostomidae)
TLDR
It is suggested that geographic events causing large scale environmental disjunction, such as the uplift of mountains, are more likely to restrict gene flow amongst populations of tolerant species with broad geographic range than local climate driven environmental changes.
