Morphological and molecular studies have consistently suggested that Sminthopsis , as currently defined, is rendered paraphyletic by the kultarr (Antechinomys laniger). They have also suggested a sister relationship between the kultarr and the long-tailed dunnart. Based on DNA sequence data from multiple mitochondrial and nuclear gene loci we reassign the long-tailed dunnart (formerly Sminthopsis longicaudata) to Antechinomys. Although there is good evidence of genetic structure within the kultarr (A. laniger), it does not correspond to the two currently recognised subspecies, viz A. laniger laniger and A. l. spenceri. We conclude that Antechinomys consists of two species, A. laniger and A. longicaudatus , consistent with morphology. We suggest that the observed genetic and morphological variation within A. laniger merits a more thorough investigation of more samples from across its range to resolve the taxonomy. Kultarrs are widespread over much of inland Australia. Although only two subspecies are currently recognised, we show that a third may be present in Western Australia. We also suggest that the long-tailed dunnart be recognised as a second species of Antechinomys as A. longicaudata. [ABSTRACT FROM AUTHOR]

Zoological consultants in Western Australia survey northern quolls (a small, cat-like marsupial) for environmental impact assessment. Confronted by habitat destruction and on the verge of extinction, northern quolls are protected as a conservation significant species, yet their precarious ecological position is made visible only through zoological work. This article explores how consultative zoologists negotiate relationships between themselves and northern quolls in order to both craft detailed population studies and mobilise the species’ power to reframe human development. Traversing environmental legislation, zoologists nurture (rather than take for granted) quoll relations, manifesting an attentiveness that entangles the animal in fact-making and modes of environmental protection. Drawing from a growing compendium of multispecies scholarship, this article questions how attentiveness can bring new entanglements into being, and how these entanglements can be managed in order to both make sense of the world and level the playing field for those nonhumans who inhabit it.

Attempts to raise the concentration of milk iron in the quokka by parenteral administration of iron. Discussion of the experiments made with iron injected intraperitoneally and infused intravenously; Changes in blood components during intravenous infusion; Discovery of the fact that the rise in milk iron was not associated with a rise in plasma iron concentration.
