Rana marsupial
(2017)
How forest marsupials are affected by habitat degradation and fragmentation? A meta-analysis
(Springer, 2014)
Habitat fragmentation and degradation are important
biodiversity change drivers worldwide. Their effects have
been described for many animal groups, but little is known
about marsupials. We conducted a meta-analysis ...
"South American" marsupials from the late cretaceous of North America and the origin of marsupial cohorts
(Springer, 2005-12)
Newly described marsupial specimens of Judithian (late Campanian) and Lancian (Maastrichtian) age in the western interior of North America (Wyoming to Alberta) have dental morphologies consistent with those expected in ...
Evolution of diet in extant marsupials: emergent patterns from a broad phylogenetic perspective
(Wiley Blackwell Publishing, Inc, 2020-10)
Extant marsupials are highly diverse, both morphologically and ecologically. As a key ecological factor, diet has been studied in marsupials at the species level. However, a general lack of phylogenetic integration has ...
MARSUPIAL SEX CHROMOSOME BEHAVIOUR DURING MALE MEIOSIS
(SPRINGER, 2010)
The absence of homology between sex chromosomes in marsupials strongly influences their behaviour during male meiosis. The highly differentiated X and Y chromosomes perform a precise and specific meiotic program that ...
Nova Physaloptera parasita de marsupial: (Nematoda: Spiruroidea)
(Fundação Oswaldo Cruz. Instituto Oswaldo Cruz., 2021)
Brain and Behavior of Dromiciops gliroides
(Springer, 2019-01)
AbstractWe have analyzed the internal structure of the brain of the microbiotherian marsupial Dromiciops gliroides and compared it with the brains of American and Australian marsupials. Dromiciops does not have a fasciculus ...
The pairing of X and Y chromosomes during meiotic prophase in the marsupial species Thylamys elegans is maintained by a dense plate developed from their axial elements
(2003)
Unlike eutherian males, pairing of the sex chromosomes in marsupial males during the first meiotic prophase is not mediated by a synaptonemal complex. Instead, a specific structure, the dense plate, develops during pachytene ...
Metabolic, hygric and ventilatory physiology of a hypermetabolic marsupial, the honey possum (Tarsipes rostratus)
(Springer Heidelberg, 2009-08-01)
The honey possum is the only non-volant mammal to feed exclusively on a diet of nectar and pollen. Like other mammalian and avian nectarivores, previous studies indicated that the honey possum's basal metabolic rate was ...
