the prevalence of anti-leptospiral agglutinins in sera of wildlife in southeastern australia.anti-leptospiral agglutinins were found in the serum from 18 (7 species) of 419 (25 species) animals sampled from various areas of southeastern australia. positive serologic reactions were observed in 5 of 25 (20%) brush-tailed possum (trichosurus vulpecula), 1 of 26 (3.8%) tammar wallaby (macropus eugenii), 2 of 12 (16.7%) swamp wallaby (wallabia bicolor), 1 of 3 (33.3%) koala (phascolarctos cinereus), 3 of 41 (7.3%) common wombat (vombatus ursinus), 2 of 100 (2%) bush rat (rattus fuscipes) and ...19817241704
redescriptions of the species of physaloptera rudolphi, 1819 (nematoda: spirurida) parasitic in bandicoots (marsupialia: perameloidea) in australia.the species of physaloptera rudolphi, 1819 (nematoda: spirurida) occurring in bandicoots (families peramelidae and thalacomyidae) in australia were re-examined and re-described. physaloptera peramelis johnston & mawson, 1939 was found in perameles nasuta geoffroy and occasionally in isoodon macrourus (gould) in eastern australia. ph. peragale johnson & mawson, 1940 from macrotis leucura (thomas) from the northern territory is treated as a junior synonym of ph. peramelis. ph. thalacomys johnston ...199910619061
serologic-based investigation of leptospirosis in a population of free-ranging eastern grey kangaroos (macropus giganteus) indicating the presence of leptospira weilii serovar topaz.eastern grey kangaroos (macropus giganteus) are one of the most abundant large macropodids sharing the landscape with humans. despite this, little is known about the prevalence of leptospira carriage within this species and the role that they may partake in the transmission of this disease in australia. the sera of 87 free-ranging eastern grey kangaroos, captured in the warragamba catchment area, sydney, australia, from june 2004 to november 2006, were screened against a reference panel of 22 le ...201020688651
deadly intentions: naïve introduced foxes show rapid attraction to odour cues of an unfamiliar native prey.introduced predators have caused declines and extinctions of native species worldwide, seemingly able to find and hunt new, unfamiliar prey from the time of their introduction. yet, just as native species are often naïve to introduced predators, in theory, introduced predators should initially be naïve in their response to novel native prey. here we examine the response of free-living introduced red foxes (vulpes vulpes) to their first encounter with the odour cues of a novel native prey, the lo ...201627416966
observations on graafian follicles and their oocytes during lactation and after the removal of pouch young in the marsupials isoodon macrourus and perameles nasuta.ovaries from 63 bandicoots (isoodon macrourus and perameles nasuta) were collected in order to obtain graafian follicles close to ovulation for light and electron microscopy. during the first 42 days of lactation (lactation c. 60 days), the follicles were less than 1.0 mm in diameter, whereas from 43 to 52 days, some animals had follicles up to 2.0 mm in diameter, or ovulation had occurred and new corpora lutea were present. this ovulation was associated with the lactation estrus that occurred i ...19836837478
skin structure in newborn marsupials with focus on cutaneous gas exchange.a morphological and morphometric study of the skin of a variety of newborn marsupials (dasyurus viverrinus, monodelphis domestica, trichosurus vulpecula, isoodon obesulus, perameles nasuta, phascolarctos cinereus, potorous tridactylus, petrogale penicillata, thylogale thetidi, macropus dorsalis) and of a monotreme hatchling (ornithorhynchus anatinus) was undertaken to assess the possibility of cutaneous gas exchange. additionally, the lungs of some of these species were investigated to assess it ...201829947022
molecular surveillance of piroplasms in ticks from small and medium-sized urban and peri-urban mammals in australia.natural landscape alterations as a consequence of urbanisation are one of the main drivers in the movements of wildlife into metropolitan and peri-urban areas. worldwide, these wildlife species are highly adaptable and may be responsible for the transmission of tick-borne pathogens including piroplasms (babesia, theileria and cytauxzoon spp.) that cause piroplasmosis in animals and occasionally in humans. little is known about piroplasms in the ticks of urban wildlife in australia. ticks from lo ...201829988853
landscapes within landscapes: a parasite utilizes different ecological niches on the host landscapes of two host species.parasites are distributed across populations of hosts, but also across microhabitats on or inside hosts: together the host population distribution and "host landscape" distribution comprise a part of the ecological niche of a parasite. in this paper we examine how a generalist parasite, the tick ixodes holocyclus, is distributed at both the host population and host landscape scales in two species of host (perameles nasuta and rattus rattus) that co-occur. we anaesthetized wildlife to locate tick ...201930807751
elucidating patterns in the occurrence of threatened ground-dwelling marsupials using camera-traps.establishing trends in endangered fauna against management efforts is a key but often challenging enterprise. camera-traps offer a new and literal window into monitoring many different mammalian species. getting it right demands seeking baseline information about how often target species interact with these devices, prior to setting a long-term monitoring strategy. we used a camera-trap array to collect detection data on three species of threatened ground-dwelling marsupials in south-eastern mai ...201931684179
when does an alien become a native species? a vulnerable native mammal recognizes and responds to its long-term alien predator.the impact of alien predators on native prey populations is often attributed to prey naiveté towards a novel threat. yet evolutionary theory predicts that alien predators cannot remain eternally novel; prey species must either become extinct or learn and adapt to the new threat. as local enemies lose their naiveté and coexistence becomes possible, an introduced species must eventually become 'native'. but when exactly does an alien become a native species? the dingo (canis lupus dingo) was intro ...201222355396
marsupial cells in long-term culture.cell lines have been developed from several species of australian marsupials and studied during long-term growth. cell lines developed from macropodid skin or heart tissues all had reproducible finite life-spans. however, cell lines developed from dasyurids showed bariable behavior in culture: lines developed from antechinus stuartii and dasyurus viverrinus had finite life-spans, while lines developed from sminthopsis crassicaudata had indefinite life-spans. s. crassicaudata lines usually became ...1977559639
onchocerca-like lesions induced by the filarioid nematode cercopithifilaria johnstoni, in its natural hosts and in the laboratory rat.histo-pathological analysis of the eyes, ears, skin and associated skeletal muscles of the back of 14 animals infected with a filarioid worm with dermal microfilariae, cercopithifilaria johnstoni: seven rattus fuscipes, of which four were naturally infected, two marsupials, perameles nasuta and isodon macrourus, and five r. norvegicus. this filarioid nematode induces skin and eye lesions in all the infected animals. these lesions are similar to those described earlier with other filarioid specie ...19938154782
hydrological features and the ecological niches of mammalian hosts delineate elevated risk for ross river virus epidemics in anthropogenic landscapes in australia.the current understanding of the landscape epidemiology of ross river virus (rrv), australia's most common arthropod-borne pathogen, is fragmented due to gaps in surveillance programs and the relatively narrow focus of the research conducted to date. this leaves public health agencies with an incomplete understanding of the spectrum of infection risk across the diverse geography of the australian continent. the current investigation sought to assess the risk of rrv epidemics based on abiotic and ...201829554980
novel hepaci- and pegi-like viruses in native australian wildlife and non-human primates.the flaviviridae family of positive-sense rna viruses contains important pathogens of humans and other animals, including zika virus, dengue virus, and hepatitis c virus. the flaviviridae are currently divided into four genera-hepacivirus, pegivirus, pestivirus, and flavivirus-each with a diverse host range. members of the genus hepacivirus are associated with an array of animal species, including humans, non-human primates, other mammalian species, as well as birds and fish, while the closely r ...202033240526
fine-scale habitat heterogeneity influences occupancy in terrestrial mammals in a temperate region of australia.vegetation heterogeneity is an inherent feature of most ecosystems, characterises the structure of habitat, and is considered an important driver of species distribution patterns. however, quantifying fine-scale heterogeneity of vegetation cover can be time consuming, and therefore it is seldom measured. here, we determine if heterogeneity is worthwhile measuring, in addition to the amount of cover, when examining species distribution patterns. further, we investigated the effect of the surround ...201526394327

digestive performance and selective digesta retention in the long-nosed bandicoot, perameles nasuta, a small omnivorous marsupial.bandicoots are opportunistic omnivores that feed on invertebrates, fungi and both epigeal and hypogeal plant parts. we examined the performance of the digestive tract of the long-nosed bandicoot (perameles nasuta) in terms of intake and total digestibility, patterns of excretion of inert digesta markers, and likely sites of digesta retention, on two diets designed to mimic part of their natural plant and insect diets. on the insect diet (mealworm larvae), bandicoots virtually maintained body mas ...19957884066
investigating dental variation in perameles nasuta geoffroy, 1804, with morphological evidence to raise p. nasuta pallescens thomas, 1923 to species rank.the long-nosed bandicoot, perameles nasuta geoffroy, 1804, found on the east coast of australia, has two subspecies, p. n. nasuta geoffroy, 1804 and p. n. pallescens thomas, 1923. until recently, this distinction has remained untested by either morphological or molecular studies. based on a recently published but limited molecular study, two publications have recommended that p. pallescens be treated as a species distinct from p. nasuta. here, the morphological distinction between p. pallescens ...201627395136
