The Blood of Carnivorous Marsupials: Low Hemoglobin Oxygen Affinity
Physiological Zoology, 1995We examined the blood of four dasyurid marsupials, all small, active insectivores and/or carnivores, to establish if there were any specializations in oxygen transport. All four species had hemoglobins with a low affinity for oxygen. This was demonstrated by high $P_{50}$'s (the partialpressure of oxygen [PO₂] at which the hemoglobin is half-saturated ...

The response of marsupial carnivores to production forest landscapes and operations
2023In a world increasingly dominated by modified landscapes, finding ways to protect threatened wildlife beyond protected areas is a priority. Forestry can degrade landscapes and impact biodiversity, but production forests often support more biodiversity than other land uses such as agriculture.

Comparison of Skull Shape in Marsupial and Placental Carnivores
Australian Journal of Zoology, 1986A set of 11 measurements on 40 species of placental (Order Carnivora) and marsupial (Order Dasyurida) carnivores is analysed by means of correspondence analysis. Dasyurida have long mandibles and tooth rows, large muscle attachment areas on the mandible, long moment arms of the temporalis and masseter, and a low occiput and short temporal fossa.

Genetic diversity and population structure of Tasmanian devils, the largest marsupial carnivore
Molecular Ecology, 2004AbstractGenetic diversity and population structure were investigated across the core range of Tasmanian devils (Sarcophilus laniarius; Dasyuridae), a wide‐ranging marsupial carnivore restricted to the island of Tasmania. Heterozygosity (0.386–0.467) and allelic diversity (2.7–3.3) were low in all subpopulations and allelic size ranges were small and ...

Gender and parental influences on the growth of a sexually dimorphic carnivorous marsupial
Journal of Zoology, 2008AbstractThe life histories of carnivorous marsupials, or dasyurids, make them useful subjects for studying maternal investment, such as sex ratio and lactational investment. One group of annual breeding dasyurids are male semelparous, strongly sexually dimorphic, produce large litters that weigh two to three times the weight of the mother at weaning ...

Guild structure of the large marsupial carnivores in Tasmania
1995The principal focus of community ecology is to detect patterns in natural assemblages of plants and animals and explain the causal factors that underlie them. For the last 30 years, much of ecological theory has assumed that competition is the primary structuring force in communities.

Tooth enamel structure of some Australian carnivorous marsupials
Alcheringa: An Australasian Journal of Palaeontology, 1999The tooth enamel structure of several specialized marsupial carnivores belonging to the Polyprotodonta and Diprotodonta were studied using scanning electron microscopy and are described in detail for the first time. Within the Polyprotodonta Dasyurus shows a simple schmelzmuster with radial and aprismatic enamel only, whereas the highly specialized ...

Predation of Noisy Pitta nestling by the Subtropical Antechinus, a carnivorous marsupial
Australian Field Ornithology, 2018Direct observations of predators taking birds' eggs and nestlings in Australia are rare, especially those involving mammals, which are largely nocturnal. Here we present photographic evidence of a Subtropical Antechinus Antechinus subtropicus (Marsupialia: Dasyuridae) taking a Noisy Pitta Pitta versicolor nestling from the nest, despite being smaller ...

Dynamics, habitat use and extinction risk of a carnivorous desert marsupial
Journal of Zoology, 2018AbstractAnimals in hot desert environments often show marked fluctuations in population size, persisting in low numbers in refuge habitats during dry periods and expanding after rain when resources increase. Understanding drought‐wet cycle dynamics is important for managing arid ecosystems, particularly if populations of threatened species are present.
