AI Article Synopsis
- A study was conducted on 31 eastern quolls, both wild-caught and captive-bred, to evaluate their health after being translocated to a reserve in Australia from 2016 to 2017.
- Six out of 21 quolls tested positive for a specific herpesvirus, showing that seropositive quolls had higher weights and altered biochemical markers compared to seronegative quolls.
- Despite finding various potential pathogens, including ticks, mites, and hemoprotozoans, the overall health of the quolls was good, supporting their translocation and establishment of a viable population.
Article Abstract
We evaluated the health of 31 (eight males, 23 females) founder eastern quolls (), translocated to a fenced reserve in the Australian Capital Territory between February 2016 and July 2017. Quolls were wild caught in Tasmania (16 animals) or captive bred at Mount Rothwell Biodiversity Interpretation Centre, Victoria (15 animals). Quolls were assessed for the presence of selected potential pathogens (, herpesviruses, serovars, hemoprotozoa, and ectoparasites). We assessed the relationships among sex, provenance (captive or free ranging), or herpesvirus infection, weight, and hematologic and biochemical variables. Six of 21 quolls (29%) tested were seropositive for antibodies to . Seropositive quolls weighed significantly more and had significantly lower potassium levels, anion gaps, and urea and triglyceride levels than seronegative quolls had. Eighteen of 31 (58%) combined conjunctival-pharyngeal-cloacal swabs collected from quolls were PCR positive for a newly identified gammaherpesvirus, tentatively named . There were no significant differences among hematologic and biochemical variables or body weights from PCR-positive and PCR-negative quolls. Eighteen of 18 (100%) of rectal-swab samples were culture negative for serovars. Three species of tick (, , and ), two species of mite (, one unidentified), and four species of flea (, , , and ), were detected on wild-caught quolls, whereas a fifth species of flea, , was detected only on captive-bred quolls. Five of 15 blood samples (33%) were positive for hemoprotozoan DNA via PCR, a novel species, a novel species, , and were detected. Despite the presence of several potential pathogens known to be associated with disease in other marsupials, the quolls were considered to be in good general health, suitable for translocation, and a viable population was subsequently established.

Land use influences the faecal glucocorticoid metabolites of multiple species across trophic levels.

Human landscape modification is amongst the greatest drivers of biodiversity loss. Measuring faecal glucocorticoid metabolites (FGM) in wildlife is of great value to measure the impact of human activities on local biodiversity because FGM offer a non-invasive way of measuring an animal's response to changes in its environment in the form of adrenocortical activity. Here, we measure the concentration of FGM in three native Australian mammal species belonging to different trophic levels: the Tasmanian devil () and the spotted-tailed quoll (), both carnivores, and an omnivore that is primarily an arboreal folivore, the brushtail possum (), and compare the FGM concentrations across three major land uses: agricultural, plantation and National Parks.

Article Synopsis
- - The eastern quoll, an endangered marsupial from Australia, has lost its mainland populations and now only exists on two islands, leading to efforts for captive breeding and re-establishment on the mainland.
- - Researchers created a high-quality reference genome for the eastern quoll, aiding in genetic management and providing insight into its demographic history, which shows signs of long-term decline starting in the late Pleistocene.
- - The study also discovered a genetic deletion at the ASIP locus that may explain the color differences in fur between the eastern quoll and the closely related Tasmanian devil.
Human habitat modification, not apex scavenger decline, drives isotopic niche variation in a carnivore community.

Article Synopsis
- Top carnivores, like Tasmanian devils, influence ecological communities through competition and predation, but human habitat disturbance also plays a significant role.
- A study analyzing stable isotopes showed that the decline of Tasmanian devils affected both their own and spotted-tailed quolls' ecological niches, with narrower niches observed in human-altered environments.
- Overall, the research found that anthropogenic disturbances impact mammalian carnivore niches more than the decline of top carnivores themselves, suggesting a complex interplay between these factors.
Wildlife Conservation on Private Land: A Social-Ecological Systems Study.

As human activity accelerates the global crisis facing wildlife populations, private land conservation provides an example of wildlife management challenges in social-ecological systems. This study reports on the research phase of 'WildTracker' - a co-created citizen science project, involving 160 landholders across three Tasmanian regions. This was a transdisciplinary collaboration between an environmental organisation, university researchers, and local landholders.

Among marsupials, the endangered numbat (Myrmecobius fasciatus) is the only obligate myrmecophage with a diet comprised strictly of termites. Like many other specialised myrmecophagous mammals, numbats have a gracile and highly specialised skull morphology with an elongated rostrum and small braincase. Myrmecobiidae is one of four taxonomic families within the Australasian marsupial order Dasyuromorphia, and to date, the muscular anatomy of any member of this group is relatively poorly known.
