Vestigial structures and variation in the evolution of the marsupial mammal dental development—a study of the woolly opossum Caluromys philander [PDF]

open access: yes, 2022
The pattern of dental replacement in marsupial mammals has received much attention for its derived nature and potential relationship to the life history of the group.

A geometric morphometric analysis of cranial and mandibular shape variation of didelphid marsupials

open access: yesHystrix, the Italian Journal of Mammalogy, 2000
<strong>Abstract</strong> The New World marsupial family Didelphidae is one of the oldest among mammals and is usually regarded as a morphologically conservative group. We analyzed cranial shape variation among six species of the six largest

New records of two marsupials (Didelphimorphia, Didelphidae) and conservation notes from southern Mexico [PDF]

open access: yesNeotropical Biology and Conservation
In Mexico opossums are difficult to find, and much of their natural history, ecology, and behavior are unknown. Through photographic and visual records, we obtained data on the presence of two species of marsupials in southern Mexico.

História natural e biologia reprodutiva de marsupiais no Pantanal, Mato Grosso, Brasil Natural history and reproductive biology of marsupials from Pantanal, Mato Grosso, Brazil

open access: yesZoologia (Curitiba), 2009
Three forested habitats at Pantanal of Poconé (Mato Grosso) were sampled during 17 months, with an effort of 38,635 trap-nights, resulting in a 6.3% of trapping success. Six marsupial and eight rodent species were recorded.

Molecular discrimination of pouched four-eyed opossums from the Mamirauá Reserve in the Brazilian Amazon [PDF]

open access: yes, 2006
Previous cytochrome B (CytB) mtDNA studies have suggested four species for the opossum genus Philander (four-eyed opossums), three (P. mcilhennyi, P. andersoni and P. opossum) from the Amazon and one (P.

A nearly complete juvenile skull of the marsupial Sparassocynus derivatus from the Pliocene of Argentina, the affinities of “sparassocynids”, and the diversification of opossums (Marsupialia; Didelphimorphia; Didelphidae) [PDF]

open access: yes, 2020
“Sparassocynids” are small, carnivorously-adapted marsupials known from the late Miocene and Pliocene of South America, thought to be relatives of living didelphid opossums but of otherwise uncertain phylogenetic relationships.

The parasitism of Ixodes luciae (Acari: Ixodidae) on marsupials and rodents in Peruvian Amazon O parasitismo do Ixodes luciae (Acari: ixodidae) em marsupiais e em roedores na Amazônia Peruana

open access: yesActa Amazonica, 2009
In this work the infestation with I. luciae on Didelphimorphia and Rodentia in different environments of Peruvian Amazon was studied. Didelphimorphia was represented by the family Didelphidae.

Common distribution patterns of marsupials related to physiographical diversity in Venezuela [PDF]

open access: yes, 2014
The aim of this study is to identify significant biotic regions (groups of areas with similar biotas) and biotic elements (groups of taxa with similar distributions) for the marsupial fauna in a part of northern South America using physiographical areas ...

Phylogenetic measures applied to the conservation of Mexican marsupials

open access: yesRevista Mexicana de Biodiversidad, 2015
The didelphimorphs in Mexico are found all over the country except for the Baja California Peninsula. The aim of this study was to use three methods to assess the phylogenetic diversity of the species: Marmosa mexicana, Tlacuatzin canescens, Caluromys ...
