Global priorities for conservation across multiple dimensions of mammalian diversity [PDF]

open access: yes, 2017
Conservation priorities that are based on species distribution, endemism, and vulnerability may underrepresent biologically unique species as well as their functional roles and evolutionary histories.

Marsupial-specific microRNAs evolved from marsupial-specific transposable elements [PDF]

open access: yesGene, 2009
Using a direct miRNA cloning strategy we previously identified fourteen marsupial- or species-specific microRNAs in the marsupial species Monodelphis domestica. In the present study we examined each of the pre-miRNAs and their flanking sequences and demonstrate that half of these miRNAs evolved from marsupial-specific transposable elements.

Molecular conservation of marsupial and eutherian placentation and lactation

open access: yeseLife, 2017
Eutherians are often mistakenly termed ‘placental mammals’, but marsupials also have a placenta to mediate early embryonic development. Lactation is necessary for both infant and fetal development in eutherians and marsupials, although marsupials have a ...

Marsupials and monotremes sort genome treasures from junk [PDF]

open access: yes, 2016
A recent landmark paper demonstrates the unique contribution of marsupials and monotremes to comparative genome analysis, filling an evolutionary gap between the eutherian mammals (including humans) and more distant vertebrate ...

Disparity of turbinal bones in placental mammals

open access: yesThe Anatomical Record, EarlyView.
Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

The transcriptomic evolution of mammalian pregnancy:gene expression innovations in endometrial stromal fibroblasts [PDF]

open access: yes, 2016
The endometrial stromal fibroblast (ESF) is a cell type present in the uterine lining of therian mammals. In the stem lineage of eutherian mammals, ESF acquired the ability to differentiate into decidual cells in order to allow embryo implantation.

Ontogeny of the malleus in Mesocricetus auratus (Mammalia, Rodentia): Systematic and functional implications for the muroid middle ear

open access: yesThe Anatomical Record, EarlyView.
Abstract The three mammalian auditory ossicles enhance sound transmission from the tympanic membrane to the inner ear. The anterior anchoring of the malleus is one of the key characters for functional classification of the auditory ossicles. Previous studies revealed a medial outgrowth of the mallear anterior process, the processus internus ...

Efficiency of small mammal trapping in an Atlantic Forest fragmented landscape: the effects of trap type and position, seasonality and habitat

open access: yesBrazilian Journal of Biology
Trapping methods can strongly influence the sampling of mammal communities. This study compared the efficiency of the capture of small mammals in Sherman traps in two positions (at ground level and in trees) and pitfall traps in a fragmented landscape ...

Serologic and Molecular Evidence of Vaccinia Virus Circulation among Small Mammals from Different Biomes, Brazil

open access: yesEmerging Infectious Diseases, 2017
Vaccinia virus (VACV) is a zoonotic agent that causes a disease called bovine vaccinia, which is detected mainly in milking cattle and humans in close contact with these animals.

Genetic Structure and Gene Flow in Eastern Grey Kangaroos in an Isolated Conservation Reserve

open access: yesDiversity, 2021
Dispersal is a key process for population persistence, particularly in fragmented landscapes. Connectivity between habitat fragments can be easily estimated by quantifying gene flow among subpopulations. However, the focus in ecological research has been
