..., with the dominant species changing from peak to peak. The deer mouse ( Peromyscus maniculatus ) fluctuated irregularly, completely disappearing from the catch for 5 years in the early 1990s. Weasels were rare for the first 25 years of small rodent changes and marten were absent, but since 2000 marten have colonized...

...Peter McDonald; Chris Pavey Populations of Australian desert rodents are known to undergo booms in response to resource pulses following periods of high rainfall. Australia's arid-adapted Tyto owls have been recorded responding functionally and numerically to these small mammal booms, though...

... Tasmania, through the examination of regurgitated pellets. Mammals dominated the diet at all but one of the sites, with introduced rodents (mostly introduced Black Rat Rattus rattus and House Mouse Mus musculus) prominent in the diet at all sites. Bandicoots (mostly the Eastern Barred Bandicoot Perameles...

...Murray Ellis Four large rodent species (Greater Stick-nest Rat Leporillus conditor , Long-tailed Hopping-mouse Notomys longicaudatus . Plains Rat Pseudomys australis and Long-haired Rat Rattus villosissimus ) have been identified among the subfossil remains collected at Mootwingee National Park...

... to the perceived risk it poses to endemic land birds and breeding seabirds. However, its main diet there comprises Rattus rattus and House Mice Mus musculus and because it is proposed to eradicate these rodents from the island in 2019, the owls are also scheduled for removal then due to the likelihood...

... from sea level to over 1000 m, and annual rainfall from 600-1800 mm, but are unified by a dense ground cover and waterlogging red or white sandy clays. Some potential threats to these rodent's populations are postulated including loss of ground cover and clearing of habitat in coastal regions. Despite...

... the borders of New South Wales while eight species are entirely extinct. Most losses (21 species) occurred before 1900, particularly in the arid western region of the State. Overall, State-level extinctions represent 39.3 per cent of native rodents (11 of 28 species), 27.0 per cent of marsupials (17 of 63...

... native mammals) employ periods of daily torpor or prolonged multi-day torpor (hibernation) to conserve energy. Daily torpor is used by dasyurids (e.g. dunnarts, antechinus, quolls), myrmecobiids (numbat), tarsipedids (honey-possum), petaurid possums (e.g. sugar glider), rodents (but only known...

... across a range of global contexts. Here we discuss recent research that demonstrates the power of strategically deploying olfactory misinformation to reduce predation on birds by predators, consumption of vulnerable seedlings by herbivores, and seeds by rodents as well as how multimodal misinformation...

...Steven L. Stephenson; Todd F. Elliott; Kelsey Elliott; Karl Vernes ABSTRACT Little is known about species of myxomycetes associated with vertebrate dung in Australia. In the present study, dung samples of 15 species of mammals (eight marsupials, three native rodents and four domestic or feral...

... and other disturbance events at which time the pair and their offspring were observed to exploit disturbed habitat and newly created forest edges in search of prey. Breeding activity was supported by an increased dietary focus on introduced rodents and other mammals displaced during habitat clearing...

...David Paull; David Milledge; Phil Spark; Sally Townley; Kevin Taylor Habitats where rodents breed and congregate provide key refuge and foraging resources and as such may be important for the survival of local populations. The habitat characteristics at spring-time breeding and congregation sites...

...Kristy Graham; Grant Blackwell; Dieter Hochuli The Hastings River mouse Pseudomys oralis is a rare Australian rodent with a patchy distribution in north-east NSW and southern Queensland. The micro-habitat requirements of the species are poorly known, although the majority of known records...

... the Torrington area, in the western part of the New South Wales New England Tablelands bioregion, is documented. The specimen record comprised an intact fresh skull and was distinguished from other rodent species on the basis of dental and cranial characters. This record is significant as one of the first modern...

... survey protocol (using pitfall traps, Elliott traps and nocturnal and diurnal active searches). The proportion of records of snakes, pygopodids, frogs, two dragon species, the gecko Diplodactylus ciliaris and the rodent Pseudomys delicatulus was markedly greater in the pipeline than in the quadrat-based...

... correlate Riversleigh's local faunas with others from central and eastern Australia; bats correlate them with faunal assemblages in Europe; rodents correlate them with Pliocene assemblages in eastern Australia. Monotremata Marsupialia Chiroptera Muridae Pisces Amphibia Reptilia Aves...

... caused the local extinction of one native rodent and its niche appears to have been partly filled by two other native species. No associations were found between plant structural and floristic diversity and vertebrate diversity at survey sites and results probably reflected the availability of food...

... of decline of mammals, distinguishing animals in the size category of the larger native rodents (the first to decline) and those the size of small wallabies (a subsequent decline). His fieldwork indicated an approximate synchrony in decline of medium-sized mammals at two distant locations (Eyre Peninsula...
