Anatomical characterisation of the kidneys of Didelphis aurita (Didelphimorphia: Didelphidae)
Folia Morphologica, 2020 BACKGROUND: Didelphis aurita is a marsupial with wide distribution in the South American continent and highly adapted to urban centres. The objective of this study was to describe the measurements and skeletopy of the kidneys and renal vascularisation of

Second-order elasticities for ecology and evolution: Unraveling nonlinear fitness responses to perturbations. [PDF]
EcologyAbstract In ecology and evolutionary biology, understanding the relationship between vital rates (e.g., survival, development, reproduction) and population growth is essential to elucidate how life history strategies are shaped by natural selection. Yet most established demographic methods rely on linear assumptions that rank the importance of vital ...

Ultrastructure of the Epithelium of the Vaginal Complex During the Proestrus and Luteal Phases of the Estrous Cycle in the White-Eared Opossum (Didelphis albiventris). [PDF]
Anat Histol EmbryolABSTRACT The white‐eared opossum (Didelphis albiventris) is a Neotropical opportunistic marsupial widely distributed in the Brazilian territory, occupying both open and forest formations. The anatomy of the marsupial female genital tract consists of two ovaries, oviducts, double uterus, two lateral vaginae, vaginal sinus and a urogenital sinus. The two

Evolution, divergence, and convergence in the mandibles of opossums (Didelphidae, Didelphimorphia). [PDF]
Curr Zool, 2023 Abstract Didelphid marsupials are considered a morphologically unspecialized group with a generalist diet that includes vertebrates, invertebrates, and plant matter. While cranium and scapula variation has already been examined within Didelphidae, variation in mandible shape, usually associated with diet or phylogeny in other mammalian ...

Thylamys pallidior (Didelphimorphia: Didelphidae) [PDF]
Mammalian Species, 2010 Abstract Thylamys pallidior (O. Thomas, 1902) is a didelphid marsupial commonly called the white-bellied fat-tailed mouse opossum. A small mouse opossum, with tricolored pelage and a white venter, it has a seasonally incrassated tail, where fat deposits, primarily at the tail base, function in food storage.

The Southernmost Known Population of the Monito Del Monte, <i>Dromiciops gliroides</i>. [PDF]
Ecol EvolA range extension for a relict south American marsupial. ABSTRACT The monito del monte (genus Dromiciops) is a small arboreal marsupial endemic to the temperate rainforests of southern South America, and the sole extant representative of the order Microbiotheria. This lineage, considered a sister group of Australian marsupials, is of great evolutionary,

Orbit orientation in didelphid marsupials (Didelphimorphia: Didelphidae) [PDF]
Current Zoology, 2016 Usually considered a morphologically conservative group, didelphid marsupials present considerable variation in ecology and body size, some of which were shown to relate to morphological structures. Thus, changes on orbit morphology are likely and could be related to that variation.
