In order to better understand the diet and digestive morphology of these marsupials, we reviewed the literature, studied the dental morphology, conducted analysis of gastrointestinal contents, and measured the digestive tracts of: Echymipera clara, E. davidi, E. kalubu, E. rufescens, Isoodon macrourus, Microperoryctes ornata, M. papuensis and Peroryctes raffrayana. These species consume a mix of fungi, insects and plant material that is broadly consistent with the omnivorous diet characteristic of most Australian bandicoots; however, morphological observations reveal variation between species that likely reflect finer-scale differences in diet. Dental morphology suggests a wider variety of diets (insectivore, omnivore, frugivore) than on the Australian mainland (mostly omnivore). Dissections and measurements of the digestive tract of seven New Guinean species indicate variation linked to diet. The relatively short caecum in all New Guinean species, but especially in E. clara and E. kalubu, is particularly suggestive of limited consumption of fibrous plant material; the relative length of the large intestine suggests variable capacity for water reabsorption. Our dietary data also suggest that some of these species also play an important role in the dispersal of hypogeous fungi.","PeriodicalId":48851,"journal":{"name":"Australian Mammalogy","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49112789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated burrow use behaviour of bilbies in a translocated population in temperate southern Australia to determine if behaviour differed in this climatic zone. Over a 12 month period, 43 adult bilbies at Venus Bay Conservation Park were spool-and-line tracked to 118 burrows. Active burrow density was 0.55 per ha, and bilbies at the site used multiple burrows (up to 13 for males and 8 for females) and regularly moved between diurnal burrows. Male bilbies had significantly larger burrow ranges (10.2 ± 5.8 ha, MCP100, mean ± s.d.) than females (2.6 ± 1.8 ha), and were similar in size to those recorded in an arid zone population. Males’ burrow ranges tended to overlap with the burrow range of multiple other males and females. The density of burrows in the current study suggests that bilby burrows were likely to have been a common landscape feature within the southern parts of the species range prior to their local extinction. Further research is needed to determine the impact of the loss of bilby burrows from southern Australia on other burrow commensal species.","PeriodicalId":48851,"journal":{"name":"Australian Mammalogy","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48945234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One such species is the northern quoll (Dasyurus hallucatus), a marsupial predator that has recently suffered substantial declines in range and is now listed as Endangered. We conducted a systematic review of all literature relevant to the conservation and ecology of northern quolls. We reviewed 143 studies, including research articles, government and industry reports, theses, and books, and quantified research effort in terms of topic, location, and publication period. We then summarised research relevant to northern quoll taxonomy, genetics, distribution, habitat associations, diet, reproduction, movement, threats, management, and Indigenous knowledge. Research effort was higher between 2011 and 2020 than the previous four decades combined. Northern quolls in the Northern Territory were the most studied, followed by the Pilbara, the Kimberley, and Queensland populations. Most studies focused on northern quoll distribution and habitat, management, and threats – primarily cane toads, predation, and fire. We conclude with a non-exhaustive list of ten future research directions. If pursued, these future research directions should provide information critical to managing and conserving northern quolls.","PeriodicalId":48851,"journal":{"name":"Australian Mammalogy","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49048867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, numerous reported sightings, including some recent, provide some hope that it may still be extant. In 2018 and 2019, we searched for evidence of this species at sites where it had been collected in the 1930s, and at places where people have since reported seeing an animal that fits its description. Our survey, which analysed data from more than 6000 camera trap nights, 536 predator scats and 226 km of spotlight transects, was the most extensive field-based search ever undertaken for this animal; but we found no evidence for its continued existence. However, our work did detect other threatened species including a range extension for the kowari (Dasyuroides byrnei), thereby demonstrating the value of surveys like this one. Because of the vastness and inaccessibility of much of the terrain comprising the supposed distribution of C. campestris, we do not see our null result as definitive for this poorly surveyed animal; we instead hope that it provides a starting point for future surveys aimed at resolving its status.","PeriodicalId":48851,"journal":{"name":"Australian Mammalogy","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43222358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evans","doi":"10.1071/am21006","DOIUrl":"https://doi.org/10.1071/am21006","url":null,"abstract":"The success of carnivorous mammals is determined not only by their ability to locate and kill prey, but also their efficiency at consuming it. Breaking large prey into small pieces is challenging due to the strong and tough materials that make up a carcass (e.g. hide, muscle, and bone). Carnivores therefore require a diverse suite of prey-processing behaviours to utilise their catch. Tasmanian devils are Australia’s only large marsupial scavengers and have the ability to consume almost all of a carcass. To determine how they do this we analysed 5.5 hours of footage from 21 captive and wild devils feeding at carcasses. We documented 6320 bouts of 12 distinct prey-processing behaviours, performed at frequencies that varied throughout feeds and between groups. The time point in the feed influenced the types of behaviours used. This is likely due to changing prey size, as different techniques appear better suited to handling whole carcasses or large pieces (pulling and pinning) or smaller pieces (holding and manipulating). Group size impacted the frequency of social pulling behaviours, which increased with the number of animals. Our findings highlight the range of prey-processing behaviours performed by scavenging devils when handling, breaking down, and consuming a carcass. The devils’ repertoire shares similarities with large carnivores that handle and consume whole carcasses as well as small carnivores that are adept in grasping and handling smaller prey.","PeriodicalId":48851,"journal":{"name":"Australian Mammalogy","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48210680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This trade-off has been demonstrated in several taxa, such that males often host a greater parasite burden compared with female conspecifics. We suppressed testosterone in wild male eastern grey kangaroos (Macropus giganteus) for 10 weeks using a novel gonadotropin-releasing hormone (GnRH) vaccine, Bopriva. We evaluated the impact of testosterone suppression on testes width, parameters of health, tick and worm burden in kangaroos using a before-after-control-impact (BACI) experimental design. Given the potential impact of animal movement on parasite burden, core area use of a subset of males was also determined. Bopriva significantly reduced testosterone in male kangaroos as well as reducing the combined size of testes by 9.6% (P = 0.01). There was no detectable effect of testosterone suppression on parasite burden and core area use in Treated kangaroos compared to Control (placebo) and Before treatment animals. Our results suggest that a duration of suppression longer than 10 weeks may be required to observe changes in parasite burden. Overall, this study provides a suitable framework for future studies to test whether reproductive hormones influence energy allocation, parasitism, and reproductive strategies in marsupials.","PeriodicalId":48851,"journal":{"name":"Australian Mammalogy","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43658010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
